INTRODUCTION

Thank you for selecting the Excelsior High Speed Veterinary Dental Air Unit. We believe you have selected the best product available for performing basic and advanced dentistry for your veterinary patients. The design of the Excelsior uses state-of-the-art integrated computer technology together with time tested technology. This combination produces a powerful and potent tool against periodontal disease. A reinforced solid aluminum chassis surrounds the internal circuit board and pneumatics, providing a very durable and reliable unit. The dental scaler utilizes an ultrasonic principle of operation. Our state of the art circuitry converts ordinary line voltage to an operating frequency of approximately 18,000, 25,000 or 30,000 Hz. (depending on the unit selected) This frequency is then amplified and delivered to the scaling tip. As a result, the tip vibrates at this ultrasonic frequency with amplitude of 0.001 to 0.004 in. (25.4 um. to 102 um.).

In designing our unique Engler tips, water flows internally through the tip as it vibrates. As the bubbles in the lavage are bactericidal, the energy released collapses and destroys the bacterial cell walls. The water flowing internally through the tip effectively cools the area and assists in removing any debris from the operative site.

The high speed drilling handpiece allows the operator to quickly and efficiently perform the same advanced dental techniques, drilling shaping and cutting to name a few, being taught in the largest teaching hospitals and clinics around the world. The low speed handpiece is used for smoothing and polishing the tooth surface after scaling. The oil-less compressor is designed to provide years of trouble free service with only minimal owner involvement.

Engler Engineering Corporation makes every effort to verify that all parts for the device along with any optional accessories ordered were shipped from our facility in Hialeah, Florida and are included in this shipment. It is imperative that you inspect the contents and if you find any pieces missing or damaged, you must notify us immediately. All claims submitted after fifteen days of receipt will not be valid.

All devices manufactured and/or sold by Engler Engineering Corporation are built and tested to approved standards. Any modification to the device, cables or hoses, initiated by others nullifies all warranty statements. Engler Engineering Corporation will not be held liable for any injury, death or damage of any type, due to non-authorized service and / or improper installation and / or improper use of the device.

HIGH VOLUME VACUUM SYSTEM (H.V.E.)The high volume vacuum system is an air powered, self-contained oral evacuatorSystem. It is supplied with a plastic waste container and a single high-velocity hose.To operate, remove the vacuum head from holder and insert a standard oral evacuator tip into end of head extension.Slide forward the handle on the side of the hose end for vacuum. Waste from the vacuum system will collect in the attached plastic bottle. When thewaste container is 3/4 full it should be emptied. After each use, the vacuumsystem should be cleaned by running clean water or a vacuum system cleanserthrough the evacuator hose and thoroughly cleaning waste bottle.

ELECTROSURGERY HANDPIECEThe Electrosurgery electronics uses solid-state technology. The unit is ready to operate as soon as the power is applied. The unit accepts electrical power from a standard outlet and converts low frequency 60 Hz cycle to a high frequency, high voltage radio wave. This rapid reversal of current means ion positions across cellular membranes do not change. As a result, neuromuscular membranes do not depolarize and there is no danger of cardiac defibrillation at these high frequencies. Neuromuscular stimulation occurs at alternating current frequencies of less than 100,000 hertz.The frequency used in this device is above the range of neuromuscular stimulation and there is no danger of electrical shock to the patient or operator. However, this high frequency waveform produces heat rapidly and is capable of producing burns to tissue. These high frequency radio waves are transmitted from the insulated handpiece into the patient's tissue by the metallic surgical tip electrode. This device is a capacitive coupled device. The current from the surgical electrode is transmitted to the target tissue and then dissipated through the indifferent plate, thus forming a complete circuit. The use of the isolated capacitive coupled circuit is an attempt to reduce the incidence of an alternate site burn inflicted to the patient by incorrect placement of a return pad. Still care must be taken because there exists a chance of alternate site burns related to current taking the pathway of least resistance to ground. When operating, always use plastic suction tips, mouth mirror, etc.

ULTRASONIC SCALER HANDPIECE

Images are for reference only. Style and / or colors may change without notice

The ultrasonic scaler maintains optimum frequency when pressure is applied to the heat treated, flow-through tip by constantly scanning and compensating, using digital micro technology, which eliminates even partial loss of power.

HIGH SPEED HANDPIECE

Your unit may be equipped with a FIBER and NON FIBER OPTIC HIGH SPEED HANDPIECE depending on your model.

NON FIBER OPTIC HIGH SPEED HANDPIECE

This handpiece is used for advanced dentistry, including but not limited to; cutting, sectioning, and shaping cracked or broken teeth, repairing, preparing cavities etc.

FIBER OPTIC HIGH SPEED HANDPIECE

This handpiece is used for advanced dentistry, including but not limited to; cutting, sectioning, and shaping cracked or broken teeth. This handpiece is equipped with fiber optics to illuminate your working area. The Fiber optic light is activated automatically when as the handpiece is activated and the footswitch is pressed.

11

LOW SPEED HANDPIECE

This handpiece will accept all ISO, E-Type attachments. It is used with a straight handpiece and prophy angle to polish the teeth after a scaling procedure. Use only approved polishing compounds. Follow all manufacturers recommendations.Note: The high and low speed handpieces are interchangeable, however handpiece pressure will need to be modified.

THREE-WAY AIR / WATER SYRINGE

The three-way air / water syringe features• Well balanced design, and smooth styling for comfortable use.• Easy release for a speedy exchange of tips.• Fully autoclavable tips.

This handpiece allows the operator the ability to rinse the operative site with a stream of water or mist or dry / blow debris with a stream of air.

WATER BOTTLEThe two liter Heavy-Duty Bottle is specifically engineered to allow the customer to be isolated from city water. The bottled water and irrigating fluids that are commonly used in isolated water supply systems are normally packaged in bottles that are not designed to be pressurized. Transferring the liquids into the Heavy-Duty Bottle assures safety and minimizes the chance of leakage.

GETTING TO KNOW THE CONTROLSMASTER ON-OFF TOGGLETurns on air and water pressure to the systems. This toggle should be turned off whenever the unit is not in use.

WATER FLOW CONTROLSAdjusts the water flow to the handpieces. A water control knob is provided for each handpiece. Turn clockwise to decrease flow, and counter-clockwise to increase flow.Warning: Water should ALWAYS be used when operating the ultrasonic scaler.

AIR HANDPIECE PRESSURE GAUGEGives a visual indication of the air pressure delivered to the handpieces. Warning: To avoid damaged to the handpieces and to the unit, the pressure delivered to the handpieces must not exceed 60 psi.

WATER ON/OFFThe control is equipped with a Wet/Dry Toggle to activate the water flow. Move the toggle up to turn water on.

SCALER ON/OFF & POWER CONTROLThe power knob controls ON/OFF and the amplitude of the scaler tip vibration, from low (slight action) to high (vigorous action). Note: Some piezo tips migh require higher amplitude for water cavitation.

ELECTROSURGERY ON/OFF & POWER CONTROLThe power knob controls ON/OFF, amplitude and waveform of the power delivered to the electrosurgery tip, from low (coag) to high (cut+coag).

EXTERNAL WATER PRESSURE REGULATOR The water pressure regulator is located on the rear of the console. The valve controls the water pressure delivered to the handpieces and is preset at the factory to the proper operating pressure.WARNING:The water pressure regulator is set at the factory and should not be changed. Any unauthorized adjustments to the water pressure valve could increase the risk of unit failure and/or causing serious injury.

FLUSH TOGGLEAllows the operator to flush the water line while steppingon the foot control. Hold the handpieces over a basin. Flip flush togglewhile stepping on the foot control and hold about 5 seconds. Water flows only as long as you hold the flush toggle up and step on the foot control.

FOOTSWITCH CONTROL

The foot control applies air pressure to the selected handpiece. The footswitch is a responsive, high volume, variable flow that can be actuated by pressing any point on the durable, chrome-plated cover. By pressing harder on the footswitch more air pressure will be delivered to the air handpieces.

14

INSTRUCTIONS FOR OPERATION AND MAINTENACEELECTROSURGERY HANDPIECEPrinciples of Electrosurgery:The Excelsior uses a constant waveform, which produces heat very rapidly to enable the operator to vaporize or cut tissue. As tissue conducts heat, always allow 10 to 15 seconds for the tissue to cool before operating on the same area. The only variable that determines whether the Excelsior vaporizes tissue or produces a coagulum, is the rate at which heat is produced. High heat that is produced rapidly will cause vaporization while low heat produced more slowly creates a coagulum.In order to limit migration current into adjacent issue the surgical intervention must be performed in a dry field. Do not use adjacent to metallic restorations due to uncontrollable and unpredictable migration along this alternate path or near bone due to current spread and the danger of osseous necrosis.

Tissue types: Different tissue types have different electrical characteristics. The electrode drags when moving through high impedance (fibrous) tissue, requiring more power. When low impedance (muscle) tissue is encountered a lower power setting should be used. PLEASE NOTE: Excessive tissue damage can occur if the power setting is in excess of what is required to accomplish the task.

IMPORTANT ITEMS TO REMEMBER1. Never use the Electrosurgery side of the Excelsior if you are fitted with any

electrical implant device. All persons in the immediate are of the surgery should be advised of the potential hazards if they have any implant which may be affected.

2. Never use the Electrosurgery unit on a patient fitted with an electrical device, or in the immediate area of any metallic implant.

3. When operating the Excelsior, always use non-conductive implements on the patient. This includes but not excluded to suction, mirrors, probes, etc.

4. For the electrode to work efficiently, it must be kept clean on a regular basis. The best and easiest way to accomplish cleaning is with a damp cloth thick enough so it will not burn your fingers. Tissue comes off easier when the electrode is activated.

5. Suggested power setting for a cut is half to max on the dial. The cut should be without drag on the tissue. Electrodes held in place for over 2 seconds will cause tissue to burn. If you need to work on one area of tissue, always remember to allow sufficient time for the heated tissue to cool, usually 10 seconds.

6. Suggested setting for coagulating should be up to half on the dial. The electrode should be about 1 mm from the tissue surface and very slowly lifted off. The tissue should turn white. If the tissue turns brown, you are burning the tissue, the setting is too high or you are moving too slowly. If you bury the electrode into the tissue, nothing will happen. As coagulating tissue correctly is quite difficult it is suggested that you practice on a piece of steak.

15

7. Because the electrodes are of a delicate nature, they are not covered under warranty except for manufacture defect. If they are used correctly with care, they will last a considerable length of time.

8. Sparking can occur at the point of the electrode. DO NOT use electrosurgery handpiece in the presence of flammable gasses or metallic items.

INDIFFERENT GROUNDThe indifferent ground plug is located in the back of the unit, the indifferent ground pad must always be connected to the indifferent ground plug and the pad must be making good contact with the patient for the electrosurgery to work properly. A complete circuit is necessary for the flow of current. That is, electrons must leave an electrode and return to mother earth to complete the circuit. In a monopolar circuit, current flows between two electrodes held widely apart. These two electrodes are the active electrode, which is small, thereby providing a high power and current density, and the return or indifferent electrode, which is large, thereby providing a low current density. It is important to remember that the indifferent electrode is just as capable of producing injury as the active electrode. The key element in avoiding injury at the indifferent electrode is to have a large surface area of contact. In this manner, the current is dispersed over a large area, thereby reducing the current density. Consequently, the indifferent electrode must be placed over an area that will allow uniform contact with the body. If contact is only partial, current density at the indifferent electrode will be greater and injury can result. The return or indifferent electrode is often referred to as the grounding pad. This however is incorrect. The indifferent electrode carries current back to the generator, not to ground.The path of least resistance is always taken to the indifferent electrode in a monopolar circuit. As a result, consideration should be given to what the operative procedure will be when the indifferent electrode is applied to the patient. The indifferent electrode should always be as close to the operative site as possible to minimize the volume the current will need to travel. For example, the indifferent electrode is better applied to the right flank during gallbladder surgery than to a thigh. The reason is that the distance between the operative site and the indifferent electrode is diminished when applied in the right flank, thereby providing a closer and more direct pathway for the circuit to be completed. This should reduce the likelihood of injury at a site other than that intended because current flow through the body is less.

ULTRASONIC SCALER HANDPIECEThere are three different types of scaler handpieces available for your Excelsior. The 18k Sonus, 25K Marathon, 30k piezo.

The 18K Sonus scaler insert is a two-piece design, it includes removable stack, a white noes cone and interchangeable tips.

The 25K MARATHON scaler uses a removable insert. This insert is a one piece, tip and stack design that cannot be separated. In this design you use interchangeable inserts.

The 30k piezo uses a quick disconnect handpiece that uses interchangeable tips.

For the 18K Sonus handpiece, The transducer (stack) has already been installed into the handpiece. Insert a sterile tip into the nosecone, and rotate the nosecone in a clockwise direction. Firmly hand tighten but DO NOT over-tighten the tips. To remove tips use provided tip wrench. Use for loosening only.

To place an 25K MARATHON insert into the handpiece, there is no alignment necessary; the operator need only drop the insert straight into the handpiece. When the plastic from the insert meets the handpiece, push the two together to create a good seal. To change inserts, the operator need only pull the insert straight out of the handpiece and exchange it for a different one.

The 30k piezo does not have a removable insert, install a insert a sterile tip in the handpiece and firmly tighten the tip using the included tip wrench

With handpiece ready rotate the power control knob to the right, the knob will click “on” and the green LED will illuminate. This indicates that the scaler has standby power and is ready to be used. Adjust the power control knob to the minimum power setting, (counter-clockwise rotation), set the WATER CONTROL to its maximum setting by rotating it counterclockwise, (knob will rotate up to 3 and a half turns for maximum water flow) hold the handpiece over a cuspidor or sink and depress the footswitch until water comes out in a stream. This should take a few seconds. This step is done to insure proper operation of the delayed cavitation feature by removing air that may be trapped in the water lines.Set the power control and the water control to a level where you develop a fine mist at the tip. NOTE: Handpieces, Inserts and tips sent from our facility are not sterilized.IMPORTANT: Keep in mind that higher power levels tend to heat the out-flowing water. Temperature control can be achieved by balancing the power with water flow volume. Thus, high power settings require higher water flow rates and conversely low power requires lower water flow rates. The scaler is now ready for use.

IMPORTANT: Operating this device with insufficient water flow will cause the water to get hot and may cause burns to gums, lips and tongue. If the handpiece begins to get warm, stop and check water temperature. If it is hot, set the power to the lowest setting and the water at a high enough setting to provide a lukewarm mist.

17

Before placing tip into patient’s mouth, activate the scaler over a sink by depressing the footswitch. A fine mist, with the temperature between cool to lukewarm to the touch is recommended. This should be accomplished with minimal power and proper water flow.It is recommended that when a tip is placed into a patient’s mouth, the lips, cheek and tongue be retracted to prevent contact.

Place the tip into the patient’s mouth and depress the footswitch in order to activate the scaler. Bring the tip lightly to the tooth and gently move it over the surface of the tooth with an erasing motion. DO NOT allow the tip to stay in one spot for an extended period of time.A saliva ejector or included H.V.E. is recommended.

Note: This device features delayed cavitation. To avoid internal contamination by back flow this device forces clean water through the lines causing droplets to form and fall from the tip when unit is disengaged.

IMPORTANT: Excessive pressure on the tip is not necessary to remove calculus or tartar. Enamel on the teeth may be damaged or removed when using excessive pressure. The enamel may be damaged if the scaling tip is left to rest in one spot for even a few seconds. Using the tip, as a pry to remove calculus or tartar is strongly discouraged as it may damage the teeth and incidentally change the shape of the tip, which in-turn, changes the frequency. The normal power setting for most procedures should be near mid-range. Since every operator has a different technique, the power may be adjusted to satisfy specific requirements. Ultrasonic Scaling Procedures (Tip Application) is not intended for contact with Soft Tissue.

DENTAL PROCEDURES SHOULD BE PERFORMED ONLY BY QUALIFIED PERSONNEL. THIS EQUIPMENT IS FOR PROFESSIONAL USE ONLY.

CAUTION: Contact with Soft Tissue May Cause Burns.

As with any precision instrument, inserts should be handled carefully. To avoid damage to the insert, please familiarize yourself with the installation. Bent or damaged insert due to excessive force or by being dropped, should be replaced. The use of a facemask is recommended when operating the scaler, to avoid inhalation of bacterially contaminated aerosol (water mist) generated during the scaling procedure.

18

For 18K Sonus and 25K marathon, it is recommended that you do not leave inserts in the handpiece for extended periods, as water and sediment may make it difficult to remove, and cause possible damage to the insert and handpiece. O-rings for inserts may be lubricated wih vaseline.

To achieve optimum performance of your equipment, we recommend that the insert tips and piezo handpieces be replaced every 6-12 months or as needed.

19

Piezo handpiece cleaning and sterilization

Before cleaning, remove the Tip from the Handpiece. Let the Handpiece run for a couple of seconds to drain out the water and any possible contamination left inside the Handpiece. The outer surface of the handpiece should be cleaned with an antiseptic soap or solution. Rinsed off with water and wiped or sprayed with a chemical disinfectant that is compatible with the handpiece material, such as a 1:6 dilute solution of Sporicidin brand disinfectant. A sterile insert or TIP is then reassembled to the handpiece in preparation for the next patient. Warning: Do not put the Handpiece and the extension wire directly into the sterilized fluid. Any left such fluid inside the machine will interfere with the normal operations of the system.

At the end of the day with the Tip remove; the handpiece and cable should be scrubbed with an antiseptic soap or solution and then rinsed off with water. The handpiece should be scrubbed a second time with an antiseptic soap or solution and rinsed off with water.

Warning: The chemical disinfectant should not be allowed to remain on the surface longer the recommended time or material damage may result. NOTE: Components inside the handpiece are highly sensitive, so don't try to open or hit on it; this may short its life or damage it. NOTE: Do not sterilize buy autoclabe. NOTE: The suggested handpiece cleaning frequency will be everyday.

CHASSISThe chassis of your unit should be cleaned at the end of every operating day with a chemical sterilization solution. This procedure could be done by spraying a fine mist of sterilization solution onto the unit, allowing it to remain on the chassis for the length of time recommended by the manufacturer. The surface should be wiped with a clean damp cloth or as suggested by the manufacturer. Dry completely.

IMPORTANT: When using any chemical sterilization solution please follow the manufacturer’s suggested procedures.

CLEANING HANDPIECES, FOOTSWITCH AND POWER CABLESAfter each procedure, or at least once a day, it is suggested that the handpieces and cables be thoroughly cleaned and sterilized. The recommended procedure is as follows: Remove 18k Sonus stack and tip or 25K Marathon insert or piezo handpiece and tip - Sterilize these items as listed above. Clean the outer surface of the handpiece and its cable with an antiseptic soap, rinse with water and sterilize with a chemical sterilization solution. Note: If any chemicals are allowed to get into the handpiece you must flush it out with clean water.Place 18k Sonus stack and tip or 25K Marathon insert or piezo handpiece and tip into handpiece for next patient. The footswitch and power cables should be cleaned regularly by spraying a fine mist of sterilization or cleaning solution on the cables. It should remain on the

20

cables for the length of time recommended by the manufacturer. Wipe the surface with a damp cloth and dry the cables completely. If you are not sure about any of the procedures listed above or you have any questions, please do not hesitate to call us at 800-445-8581.

21

HIGH SPEED HANDPIECE:

In order to always provide the handpiece with clean air, after water is accumulated in the compressor it must be drained out ONCE A DAY. DAILY LUBRICATION IS ABSOLUTELY ESSENTIAL.Operate the handpiece at pressures of 25 to 30 pounds per square inch. The handpiece is engineered to attain speeds of 350,000 RPM at 25 pounds and 400,000 RPM at 30 pounds.Use the brush to remove foreign particles. A fine wire is provided for cleaning the water spray hole and to prevent clogging. Particles can be dislodged by blowing air backward from the contra angle head. NOTE: DO NOT attempt to blow articles from the rear end of the handpiece, as larger particles will be blocked in the water tube.

Sterilization Procedures: (Autoclave and Chemiclave Only)Clean External Surface: Remove bur from handpiece and scrub with a toothbrush or 2” x 2” gauze using warm tap water. DO NOT IMMERSE HANDPIECE.Dry: Thoroughly dry handpiece using gauze, paper towel or air syringe.Clean/Lubricate Internal Surface: Using a combination cleaner/lubricant or DCL 90, spray handpiece in drive air hole and in chuck.Expel Cleaner/Lubricant: Reinsert bur into handpiece head, connect handpiece to tubing and run for 5 seconds to thoroughly expel debris and excess lubricant.THE HANDPIECE MUST BE OPERATED ONLY WITH A BUR OR BUR BLANK. DO NOT OPERATE EMPTY.Clean Fiber optic Bundle: Using a cotton swab with isopropyl alcohol, wipe the surface on both ends of handpiece.Bag and Cycle in Autoclave: Place handpiece into autoclave bag or pouch. Cycle as per autoclave/ chemiclave manufacturer’s instructions. DO NOT EXCEED275° F (135° C).Cool Down and Lubricate: Allow handpiece to return to room temperature. Lubricate handpiece as per instructions listed above. Expel excess lubricant as per previous instructions.

22

DO_ Use warm tap water to scrub the exterior of handpiece._ Expel excess lubricant from handpiece by running it for 5 seconds after cleaning and lubricating._ Use separate cans of lubricant before and after sterilization to prevent contamination._ Clean both ends of fiber optic bundle with a cotton swab dipped in isopropyl alcohol._ Use autoclave bags and pouches with indicators to protect handpiece.

DON’T_ DON’T immerse handpiece in water or chemical disinfectants/sterilants._ DON’T use any type of disinfectant on handpiece._ DON’T sterilize handpiece with bur inserted._ DON’T exceed 275° F (135° C) in autoclave or chemiclave._ DON’T dry heat or heat transfer sterilize._ DON’T operate handpiece without bur inserted in chuck.

Do-It-Yourself Handpiece Repair (Simple Stuff)A. Handpiece has low torque or power (could be lack oflubrication or too much debris)

1. Try heavily spraying “correct” drive air tube with acombination cleaner/lubricant like DCL-90 and runhandpiece for a minute.2. Remove turbine and clean out head, lubricateturbine directly, and spin bearings with fingers. Blowcompressed air in head of handpiece to clear airtube. Return turbine to handpiece and run.3. Check air pressure on dental unit.

B. Burs are sticking inside of turbine or falling out1. Flush the spindle with a handpiece cleaner wherethe bur would normally be inserted.2. Ensure that burs are not less than .0625” orgreater than .0630” in diameter or are worn,which can damage spindle.

C. Water spray is weak or completely stopped1. Insert small wire into water tube from head of handpiece to remove debris.2. Use our Smart Cleaner to clear clogged tube.

If these simple solutions fail, more serious problems are likely affecting the handpiece, which should be sent to a reputable repair service provider.

INSERTING A BUR/DIAMOND INTO THE HANDPIECE: CHANGING BURSLares highspeed handpieces may be used with friction grip burs or diamonds with shank diameters that conform to ISO and ADA size standards. Neveruse burs with carbide shanks.Reference the chart below for recommended bur and diamond lengths for each handpiece model:Model Recommended Optional757Euro Standard (19.0 mm) Surgical Length (26 mm) 757 Euro

1. Hold handpiece handle as shown and position end of thumb on push button with index finger wrapped around underside of handpiece neck for support.

Figure 2.2. To insert a bur, first be sure bur is clean and free of external debris or corrosion. Without depressing push button, gently insert bur into handpiece as far as possible. Then fully depress push button hard and fast while simultaneously inserting bur into chuck the rest of the way until fully seated. Release push button and insertion is completed.

Caution: Be sure to tug firmly on the bur/diamond immediately after completing the insertion procedure described above to verify full seating and secure retention of the bur/diamond before operation.

3. To remove a bur, fully depress push button hard and fast while simultaneously pulling bur until removed from chuck.

Figure 2. Push button may then be released until next bur is inserted.Caution: Never force bent, rusted or oversize bur into chuck or damage may occur voiding warranty. Never depress push button during handpiece operationor while turbine is still rotating. Be sure to remove bur at end of day.

CONNECTING HANDPIECE TO SWIVEL COUPLER1. Lubricate the handpiece (See Maintenance and Infection Control).2. Attach the coupler to the dental unit hose securely.

A. Align pins on the coupler with the tubing.B. Thread the hose nut onto the couplerC. Fit the coupler wrench to the flats and tighten the hose nut.

Figure 3.

24

3. Holding the swivel coupler in straight alignment with the back of the handpiece, gently insert the swivel coupler into the back of the handpiece, pushing more firmly when fully inserted until the coupler snaps with a “click” sound on the back end of the handpiece indicating complete engagement. Never force engagement or swivel coupler will be damaged.

Figure 4.4. With bur engaged, operate handpiece to expel excess lubricant. Wipe off

any excess lubricant expelled with a towel or cloth.

ADJUSTING SPRAY PATTERNOn a properly adjusted delivery system, the spray pattern of your Lares handpiece covers all bur/diamond lengths with a consistent, homogeneous air/water mixture.Holding handpiece over cuspidor, depress the foot control to test spray pattern. To increase or decrease the amount of water present in the spray, adjust the coupler water flow ring as needed.

Figure 5.Your handpiece is now ready to operate. Be sure to follow the maintenance instructions that follow.

INITIAL MAINTENANCEClean, lubricate and sterilize a new handpiece before its first use. Follow the maintenance and infection control procedure on pages 7-9.

OPERATIONLares highspeeds should be operated using the same techniques and procedures used with other highspeed handpieces. There are, however, severalunique procedural tips that can significantly extend problem-free operating life.

TO EXTEND OPERATING LIFE1. Detach swivel handpiece from swivel coupler at the end of each day and

prior to other extended periods of nonuse to avoid water mineral deposit freeze up. Cover swivel coupler with dust cap when handpiece is detached.

2. Remember to follow all recommended maintenance and operation procedures religiously. Like most ultra high performance machinery, highspeed handpieces are intolerant of maintenance neglect and improper operation.

25

IMPORTANT SAFETY PRECAUTIONSAll highspeed handpieces are potentially dangerous if safety precautions are not followed. Be sure to read and observe the following precautions.Caution: Never use the back of the handpiece for tissue retraction, or otherwise cause push button to be depressed during operation. Doing so may resultin button getting hot and burning the patient.

1. Never operate handpiece with a bent or damaged bur/diamond engaged in chuck.

2. Never insert or remove handpiece from oral cavity before rotation of bur/diamond is completely stopped.

3. Never operate handpiece at air pressure in excess of recommended maximum settings.

4. Never operate handpiece after turbine cartridge replacement without double checking that head cap is tightened securely.

5. Never depress push button during operation.6. Never operate handpiece without fully inserting bur in chuck. Do not

extend burs.7. Never use burs that do not conform to I.S.O. and ADA shank diameter

standards or utilize carbide shanks.8. Do not use this or any other highspeed handpiece for surgical procedures

including, but not limited to, the removal of bone, dividing a tooth for extraction, or any other procedure that must be performed in the presence of an open wound. Doing so may result in subcutaneous emphysema and accompanying serious patient health hazards, including permanent disability or death. For cutting procedures that must be performed in the presence of an open wound, a surgical handpiece specifically indicated for this purpose and designed to exclude the escape of air from the surgical field must be used.

9. Do not use this handpiece without heat sterilizing between patients to prevent cross-contamination which could result in serious illness or even death from infectious organisms such as HIV (the virus that causes AIDS) or hepatitis B.

MAINTENANCE AND INFECTION CONTROLBe sure to use only Lares Handpiece Conditioner for this handpiece. Use of lubricants/conditioners other than Lares approved conditioner or failure to followthe maintenance schedule described above will automatically void the limited warranty for this product.All Lares Highspeed Handpieces may be steam autoclaved or chemiclaved.How you treat your highspeed handpieces before and after autoclaving/chemiclaving will have a dramatic impact on how well they withstand repeated cycles.Prior to cycling, be sure to have available a Lares Handpiece Conditioner can with the required nozzle hardware attached.

PROCEDURE AFTER EVERY PATIENTThis procedure should be performed after every patient to prevent cross-contamination and to assure long, trouble-free operation.

26

1. Detach handpiece from swivel coupler. (Do not autoclave/chemiclave swivel coupler). Clean external surface of handpiece thoroughly to remove saliva, blood, and other organic soil. Scrub handpiece with small brush under running water. Rinse and dry thoroughly. CAUTION: NEVER Submerge Components In Any Cleaning Or Disinfecting Solution DO NOT Use Ultrasonic Cleaners

2. Apply Lares Handpiece Conditioner. Follow specific instructions detailed on can.

3. Remove bur from chuck.4. Place handpiece in autoclave bag. The use of autoclave bags dramatically

reduces fiber optic light output deterioration and handpiece cosmetic damage.

5. Load autoclave bag containing handpiece into autoclave or chemiclave. Be sure to load autoclave bags for maximum penetration of steam or chemical vapor.

6. Cycle the handpiece according to the autoclave/chemiclave manufacturer’s instructions. Do not exceed 275°F (135°C).

CAUTION: DO NOT Autoclave or Chemiclave For Extended/Unusual Periods Of Time (Such As Overnight). DO NOT Leave Handpiece Components In Sterilizer After Cycle Is Completed.

7. Immediately remove handpiece from autoclave or chemiclave. Allow to cool sufficiently prior to handling.

8. As soon as handpiece is cool enough to handle, wipe fiber optic light transmitting surfaces clean at front and back ends of handpiece with isopropyl alcohol and cotton swab. This step is particularly critical to maintaining light output.

WEEKLY CLEANING OF SWIVEL COUPLER ROTATING SURFACEOnce each week prior to application of Lares Handpiece Conditioner remove swivel handpiece from swivel coupling and clean external surface of maleswivel connection with isopropyl alcohol and gauze pad. This will keep swivel rotating freely.

DRYERS AND FILTERSBe sure to periodically check and maintain your dental unit air filter and dryer to assure a steady supply of clean, moisture free air which allows longerbearing life.

FIBEROPTIC BULB CHANGINGCaution: Electrical shock and burn hazard. Before removing bulb, be sure swivel coupler is detached from hose for 3 minutes.

1. Grasp metal sheath covering bulb and rotate counterclockwise (when viewed from end of bulb) to loosen and remove.

2. Pull bulb straight out to remove from coupler.3. Reinstall bulb by carefully aligning bulb pins with holes in coupler bulb

socket and fully inserting bulb into socket. Then slide metal bulb sheath

27

over bulb, threaded end first. Rotate clockwise (when viewed from end of bulb) tighten sheath into coupler.

DIFFUSER CHANGING

1. Unscrew the diffuser using the wrench (Item # 10109) by aligning the posts on the wrench with the holes on the diffuser.

2. Clean the surfaces of the head and diffuser. Do not leave the o-ring inside the head. When refitting, position the oring on the diffuser, then fit the threads into the head and tighten moderately.

LOW SPEED HANDPIECE:

What is a Low (Slow) Speed Handpiece?

• A hand held motor, usually air-driven, that spins a cutting bur or prophy cup at 20,000 RPM or less.

• Used for removal of caries, refining a cavity preparation, performing prophylaxis, and other endodontic and implant procedures.

• Straight attachments that use handpiece

How Does a Low Speed Handpiece Work?• An airline is attached to the back end of the handpiece, similar to a high-

speed handpiece.• When air is introduced into the handpiece (via the chair unit foot pedal), air

is forced over the vanes of the rotor (consisting of vanes or blades), which causes it to spin.

• After the air moves around the rotor, it is forced out through the handpiece’s back end exhaust port.

E-Type Low Speed Handpieces

• Multi-piece handpieces consisting of a motor and various attachments (the motor cannot be used without an attachment).

• E-Type is an international standard for how attachments are placed on a motor; most E-Type motors and attachments are interchangeable, like

28

KaVo, NSK, W&H, and Bien Air. However, Midwest and Star brands have proprietary designs.

• 2 primary types of attachments:NOSE CONE/STRAIGHT ATTACHMENT

• Can accept straight handpiece burs, mandrels, prophy angles, and doriot/U-Type contra angles.

• Come either as a 1:1 transmission, which maintains the motor speed, or as a 4:1 gear reduction, primarily used with prophies to reduce the handpiece speed to a rate that reduces the splatter of paste and the potential to burn a patient.

INSTALLATION

1. Slide the Straight Handpiece down over the top of the low speed. 2. Line up the notch of the Prophy Angle with the Aligning Pin on the Straight

Handpiece, and then push the shaft of the Prophy Angle into the chuck of the Straight Handpiece.

3. Rotate the Lock Ring clockwise, until it clicks and locks the prophy angle in place.

4. Place a disposable rubber-polishing cup on the end of the prophy angle by snapping it on. The Prophy Angle is now secured and ready for operation.

5. Rotate the selector knob on the front of unit to either forward or reverse operation.

POLISHER OPERATION: 1. Dampen the rubber cup and place a small amount of polishing paste on it.2. Depress the footswitch and the rubber cup will begin to rotate. The speed

of rotation may be adjusted to your desired level depending on how hard you press on the footswitch.

3. To keep the paste from flying off the cup, gently bring the cup up to the toot and then maintain a low footswitch pressure to keep a low speed.

IMPORTANT: The prophy angle is only rated to rotational speeds of 5,000 RPM - therefore, in order to prevent premature failure of the angle keep the unit set in the prophy range whenever the prophy angle is attached to the straight handpiece.

4. High-speed settings may throw the polishing paste off of the rubber cup. Always start with a low speed and then adjust to a higher speed as required. Place the end of the angle into the patients’ mouth and gently apply the rubber cup to the surface of the tooth with a circular motion. Do not allow the rubber cup to remain stationary on one area for an extended period of time.

29

THREE-WAY AIR / WATER SYRINGEThis handpiece allows the operator the ability to rinse the operative site with a stream of water or mist or dry / blow debris with a stream of air. The button on the left controls water flow. The button on the right controls airflow. Pressing both buttons at the same time provides mist. The air / water syringe works independently of the other handpieces and can be used alone or with the other handpieces.The syringe features quick-change autoclavable tips: To remove a tip, presson the locking collar surrounding the tip socket and pull the used tip straight out of the socket. To insert a new tip, press locking collar and push tip intosocket as far as it will go. Release collar and gently tug on tip before using toensure that tip is securely locked into socket.

Syringe Tip Sterilization:1) Remove contaminated syringe tip.2) Remove all visible signs of contamination before autoclaving.3) Autoclave tip at 132° C (270° F) for ten minutes.4) Sterilize between each patient use.NOTE: Since only the tips can be autoclaved, it is recommended that the air/water syringe be bagged with adisposable, single-use plastic sleeve between each patient use.

WATER BOTTLEIf there is no input water or you want to use serum or distilled water for handpieces or syringe, you can use the water bottle.Fill the bottle up to ¾ of its capacity and connect it to the prepared socket. Then turn master switch ON so that the air comes into the tank and pumps out the liquid stored in the tank to the unit. In the back if the unit there is a switch for selection between external water bottle and water bottle. To select the water bottle, turn the switch to the bottle.Before removing the bottle for refilling, it must be depressurized by turning the bottle 1/4 turn counterclockwise and slightly sideways. The bottle is removed by rotating it from its quick disconnect mount at the bottom right of the chassis and then pulling down. After the tank is filled, insert it onto the quick disconnect mount and twist. The bottle will feel loose until pressurized. Cleaning and sanitation of the bottle is recommended between uses. Warning: Failure to depresurize the water bottle before removal might cause injury.

Warning: Distilled water Is strongly recommended. Engler Engineering Corporation is not responsible for damages caused by water pollutants.

SEAL-TIGHT PROPHY ANGLE

The Seal-Tight prophy angle comes standard with every Polisher. This prophy angle is a precision-engineered dental device. All of the gears and shaft assemblies are made of high-grade stainless steel, which when kept clean and properly lubricated, will provide long, trouble-free service.

General CautionsWhen operating the prophy head always consider the safety of the patient. Should the prophy head function abnormally, cease operation immediately. See below for maintenance instructions. If you need further assistance contact Engler Engineering Corporation for instructions.Do not drop the prophy head.Before use, always confirm that the brush or rubber cup is correctly seated in place.If end cap unscrews by itself during a procedure;Switch the direction of the micromotorCheck that head and end cap are screwed together firmly. A poor fit between the head and end cap requires replacement of the entire prophy angle.

IMPORTANT: The prophy angle is rated for no more 3,000 R.P.M. –High speeds will result in the polished surface heating up, spattered polish, and shorter prophy angle life. Keep the unit set in the prophy range whenever using the prophy angle. Always start with a low speed and then adjust to a higher speed as required.

INSTRUCTIONS FOR USEDampen rubber cup. Dab a small amount of polishing paste onto the rubber cup.Place the prophy angle into the patients’ mouth and gently apply the rubber cup to the surface of the tooth with a circular motion. Always begin the procedure using the lowest possible R.P.M., increase speed as necessary. Do not allow the rubber cup to remain stationary on one area for an extended period of time. Keep rotating the direction of the prophy cup, so as not to overheat one area. Add polish as needed. Move over all tooth surfaces. When finished, rinse the patient’s mouth thoroughly with plenty of water.

CLEANING AND MAINTENANCE

ENGLER ENGINEERING CORPORATION STRONGLY RECOMMENDS PERFORMING THIS STEP AFTER EACH PATIENT OR A MINIMUM OF ONCE PER DAY.Remove prophy angle from straight handpiece.Rinse under running water to remove any loose debris.Unscrew the “end cap” by turning counterclockwise either by hand or with end cap wrench provided with each prophy angle.Using a mild soap and a toothbrush, gently scrub any debris and foreign matter from the gear of the end cap. Use the toothbrush to clean the orifice inside the “head” of the prophy angle specifically the inside gear. Rinse thoroughly.Allow head and end cap to dry completely. Flushing with alcohol will hasten drying.Place 2-3 drops of oil on the gear of the end cap and inside the prophy head on the crown gear inside the head. Use the oil that is supplied with your Son-Mate. Sewing machine oil or 3-in-one oil is also acceptable.Wipe away any excess oil once assembled.DO NOT use cotton swabs, tissue paper, paper towels or cloth to wipe out the prophy head as fibers may get stuck in the gear. Should the crown gear become jammed with fibers, replacement of the entire prophy angle will be necessary as there are no replacement parts for the prophy angle.

STRAIGHT HANDPIECE

LUBRICATION:The spray nozzle oiling method is optional but highly recommended because it cleans as well as lubricates. The alternate method is to place 1 drop of approved oil in the chuck hole. Lubrication of the straight handpiece is required at least once a week.

Lubrication by spray lubricant:1. Make sure that the straight handpiece is in the unlocked position prior to

lubricating. 2. Install the E-Type nozzle by pushing it onto the top of the spray can. To

lubricate, insert the E-Type nozzle into the bottom of the handpiece. Holding the two together tightly, with can in the upright position, push spray button for 2 to 3 seconds.

NOTE: If spray time is too short oil may not be propelled into all areas of the handpiece.

33

CLEANING AND STERILIZATION

Cleaning:1. Wipe the handpiece clean with an alcohol-soaked soft tissue. 2. Never clean the handpiece in boiling water, chemical solutions, in an

ultrasonic cleaner, or with wire brushes.

Sterilization:1. Autoclaving is recommended for the Engler Straight Handpiece.2. Clean the Handpiece as described above.3. Lubricate the Handpiece as described in the lubrication section of this

manual.4. Place the Handpiece in an autoclaving pouch and seal it in 5. accordance with the instructions on the pouch.6. Autoclave for no more than 20 min. at 132 °C (270 °F).

Keep the straight Handpiece away from water vapor or mist that may settle and cause premature damage to the bearings.

IMPORTANT: If you experience problems during operation, call our repair department. DO NOT attempt to repair the straight Handpiece by removing any screws. Doing so will shift the internal springs and may cause permanent damage to the unit and will void your warranty.

34

MAIN UNIT MAINTANANCE

Flush ModeThe flush function is used to evacuate leftover water from the handpiece hoses. This procedure should be performed at the end of each day or when the Excelsior will be placed in storage for any length of time.

Using Flush:To flush the Excelsior, follow these steps with the compressor ON:

1. Disconnect (remove) the low and high-speed handpieces from their hoses by unscrewing the collar where the hose meets the handpiece.

2. If your unit is equipped with an 18k and 25k handpiece, Remove insert from scaler handpiece, DO NOT attempt to unscrew the scaler handpiece.

3. If your unit is equipped with piezo, remove the handpiece by unpluging the quick connect close to where the hose meets the handpiece .

4. Place hoses (and ultrasonic handpiece for 18k and 25k) back to their cradle.

5. Remove one handpiece hose at a time, lifting the hose from its cradle will enable the flush.

6. Flip the flush switch to the up position and press the footswitch. Air and water will now blow out through the hose. Please be sure to point the hose down into a sink or thirsty towel.

7. Once complete flip the flush switch to the down position.8. Repeat steps 5, 6, and 7 for every handpiece.9. Reinstall the handpieces and scaling insert.

Warning: When you use flush, high-pressure water and air will blow out of the handpiece connector. Place the handpiece hose end or ultrasonic handpiece end in a discharge container, a sink, or a towel. Point away from people and pets.

35

Filters

The excelsior is equiped with several filters.The Input Air filter, external water filter, water bottle filter.The Input Air filter, external water filter are located next to the water bottle.The Air and external water filter must be kept cleaned or replaced when needed.To open the Air and external water filter unscrew in the direction shown by black arrow (counterclockwise).

The water bottle filter is located inside the water bottle.The water bottle filter may be inspected and if dirty, it should be replaced. The water filter assembly is available at Engler Engineering Corporation.

To replace filter unscrew quick connect as shown, then screw in the new filter.

COMPRESSOR MAINTANACEThe compressor mechanism is oil free and maintenance free, howeverwater must be drained daily from the white water separator tank. This is necessary as air releases water when it is compressed and decompressed.

DIRECTIONS:

1. Remove pump and cap assembly. 2. Fill tank with water or medicated solution up to the

“FILL LINE” mark. Do NOT fill beyond this line.3. Replace pump and cap assembly and tighten

securely.4. Pressurize tank by pumping it approximately 10-20

times (depending on the amount of liquid used). Ifa hissing sound is detected, tank is over-pressurized. Stop pumping. Leave tank on a levelsurface until hissing stops. Insert the male quickdisconnect on the end of the waterline from scalerinto female quick disconnect provided on tank.

WATER TANK CARE & MAINTENANCE:

NOTE: A small amount of care will repay in long life and efficient operation.

a. RELEASE AIR PRESSURE by turning knob of pressure relief valve. Pull out fully and allow air to escape.

b. Loosen cap slowly. Remove pump & cap assembly. Pour out any remaining liquid & rinse all parts thoroughly with clean water.

c. Always store tank empty and with tank cap loose, upside down.

38

TROUBLESHOOTING:

PROBLEM: TANK FAILS TO PRESSURIZE.

a) Be sure cap is tight. b) Check to see if pressure relief valve is in safety position. c) Remove the pump from the tank. Turn pump handle counterclockwise and lift

handle to unlock. On top of the pump cap there is an opening that says “oil here”. Place 2 or 3 drops of oil (20 weight, household vegetable oil, etc.) into the opening. Pump several times to work the oil into the walls of the pump until it moves freely. Repeat if necessary. Screw the pump back into the tank and resume normal operations. This process should be repeated often depending on usage, or when pump starts to work harder.

d) Black particles found in water, the pump assembly is deteriorating. Order new pump assembly from Engler Engineering.

Pump assembly has been pre-lubricated...DO NOT TAKE THIS ASSEMBLY APART TO CLEAN INSIDE PUMP.

WARNING:READ AND FOLLOW ALL INSTRUCTIONS.ALWAYS INSPECT your pump before each use.ALWAYS RELEASE AIR pressure before removing pump or servicing tank, by pullingpressure relief valve knob out fully.ALWAYS TIGHTEN CAP securely, a loose cap could be forcibly ejected & cause injury.DO NOT use mechanical devices to pressurize the tank .They can create excessive anddangerous pressure which could cause the tank to explode.DO NOT STAND over pressurized tank while using it or pumping itDO NOT USE solutions hotter than 105F.D0 NOT damage or alter the functions of the pressure relief valve or plug the pressure relief valve hole, as this could cause the tank to explodeDO NOT pressurize the tank until ready for use.DO NOT lift or carry the tank by waterline, extension rod or pump handle unless it is securelylocked in place.

CARE AND MAINTENANCE OF YOUR PORTABLE WATER TANKTo keep slime from forming inside the tank and eventually getting into the dental unit: Every two weeks dispose of water in tank. Pour 1/2 cup of bleach and one quart of hot water into tank and swirl the liquid thoroughly inside the tank. DO NOT PLACE pump assembly in tank with Clorox solution as lubrication inside the assembly may react with the mixture. Dispose of the bleach mixture and rinse the tank out. You can allow the tank to dry overnight or fill it again with distilled water. Clean the outside of the pump assembly with paper towels and alcohol. The pump assembly has been pre-lubricated. DO NOT TAKE THIS ASSEMBLY APART.

FREQUENTLY ASKED QUESTIONS

How often should I lubricate my highspeed handpiece?• We recommend that you only lubricate with Lares Handpiece Conditioner

prior to sterilization.

How Fast Does a Low Speed Handpiece Run?• The speed depends upon the pressure (PSI) of the air supply, the

configuration of the rotor components, and the gears inside the motor.• Low speed handpieces are designed to handle much more air pressure

than high speed handpieces.• Typical low speed motors, without gear reductions, running at 40 PSI

should spin at approximately 20,000 rpm.• Speed reducing gears allow the handpiece to generate significantly more

torque.• Hygienist handpieces and low speeds used for prophylaxis generally

operate at 5,000 RPM.• Endodontic and implant procedures use attachments to reduce the speed

to 1,500 rpm or less and generate very high levels of torque for optimal control.

How Long Will a Low Speed Handpiece Last?• Slow speed handpieces can have long life spans due to the low operating

speeds and design differences (compared with high speed handpieces.)• The handpieces can be repeatedly overhauled but should have

professional maintenance conducted every 6-12 months.

What Type of Handpiece Connections and Tubing Compatibility Does a Low Speed Handpiece Have?

• Similar to high speed handpieces, low speed handpieces can be either fixed back or quick disconnect style, with 2 different tubing configurations: 2 hole and 4 hole.

• Because low speed handpieces operate at significantly lower speeds than high speed handpieces, there is less need for cooling the tooth with air and water spray.

• Therefore, most low speed motors are configured so that no water is transferred through the water tubes; however, low speed handpieces still maintain the international standard backends that high speed handpieces have, for the sake of compatibility with tubing.
