This product may contain chemicals known to the State of California to cause cancer, birth

defects or other reproductive harm.

Some dust created by power sanding, sawing, grinding, drilling, and other construction activities

contains chemicals known to the State of California to cause cancer, birth defects, or other

reproductive harm. Some examples of these chemicals are:

- lead from lead-based paints,

- crystalline silica from bricks and cement and other masonry products, and

- arsenic and chromium from chemically-treated lumber.

Your risk from these exposures varies, depending on how often you do this type of work. To

reduce your exposure to these chemicals: work in a well-ventilated area, and work with approved

safety equipment, such as dust masks that are specially designed to filter out microscopic

particles.

Handling power cords on corded products may expose you to lead, a chemical known to the State

of California to cause cancer and birth defects or other reproductive harm. Wash your hands after

handling.

WORK AREA SAFETY

Inspect the work area before each use. Keep work area clean, dry, free of clutter, and well lit.

Cluttered, wet, or dark work areas can result in injury. Using the tool in confined work areas may

put you dangerously close to other cutting tools and rotating parts.

Page 6 of 30

PERSONAL SAFETY

Stay alert, watch what you are doing, and use common sense when operating the saw. Do not

use the saw while you are tired or under the influence of drugs, alcohol, or medication. A moment

of inattention while operating the saw may result in serious personal injury.

Dress properly. Do not wear loose clothing, dangling objects, or jewelry. Keep your hair, clothing

and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving

parts.

Wear the proper personal protective equipment when necessary. Use ANSI Z87.1 compliant

safety goggles (not safety glasses) with side shields, or when needed, a face shield. Use a dust

mask in dusty work conditions. Also use non-skid safety shoes, hardhat, gloves, dust collection

systems, and hearing protection when appropriate. This applies to all persons in the work area.

Do not overreach. Keep proper footing and balance at all times.

Do not use the saw when tired or under the influence of drugs, alcohol or medication.

Ensure the power switch is off prior to plugging in the tool.

Remove keys or wrenches before connecting the tool to an air supply, power supply, or turning on

the saw. A wrench or key that is left attached to a moving part of the saw may cause personal

injury.

Secure the work with clamps or a vise instead of your hand when practical. This safety precaution

allows for proper tool operation using both hands.

ELECTRICAL SAFETY

Grounded tools must be plugged into an outlet properly installed and grounded in accordance

with all codes and ordinances. Never remove the grounding prong or modify the plug in any way.

Do not use any adapter plugs. Check with a qualified electrician if you are in doubt as to whether

the outlet is properly grounded. If the tools should electrically malfunction or break down,

grounding provides a low resistance path to carry electricity away from the user.

Double insulated tools are equipped with a polarized plug (one blade is wider than the other). This

plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the

plug. If it still does not fit, contact a qualified electrician to install a polarized outlet. Do not change

the plug in any way. Double insulation eliminates the need for the three wire grounded power cord

and grounded power supply system.

Do not allow the product to come into contact with an electrical source. The tool is not insulated

and contact will cause electrical shock.

Avoid body contact with grounded surfaces such as pipes, radiators, ranges, and refrigerators.

There is an increased risk of electric shock if your body is grounded.

Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the

risk of electric shock.

Do not abuse the power cord. Never use the power cord to carry the tools or pull the plug from an

outlet. Keep the power cord away from heat, oil, sharp edges, or moving parts. Replace damaged

power cords immediately. Damaged power cords increase the risk of electric shock.

When operating a power tool outside, use an outdoor extension cords marked “W-A” or “W”.

These extension cords are rated for outdoor use, and reduce the risk of electric shock.

SAW USE AND CARE

Do not force the saw. Products do a better and safer job when used in the manner for which they

are designed. Plan your work, and use the correct product for the job.

Check for damaged parts before each use. Carefully check that the saw will operate properly and

perform its intended function. Replace damaged or worn parts immediately. Never operate the

product with a damaged part.

Do not use the saw with a malfunctioning switch. Any power tool that cannot be controlled with

the power switch is dangerous and must be repaired by an authorized service representative

before using.

Disconnect the power/air supply from the saw and place the switch in the locked or off position

before making any adjustments, changing accessories, or storing the tool. Such preventive safety

measures reduce the risk of starting the tool accidentally.

Store the saw when it is not in use. Store it in a dry, secure place out of the reach of children.

Inspect the tool for good working condition prior to storage and before re-use.

Use only accessories that are recommended by the manufacturer for use with your product.

Accessories that may be suitable for one product may create a risk of injury when used with

another tool. Never use an accessory that has a lower operating speed or operating pressure

than the tool itself.

Keep guards in place and in working order. Never operate the product without the guards in

place.

Do not leave the tool running unattended.

Cutting Hazard. DO NOT operate with guard removed. Keep hands clear of blade.

Be especially careful to keep fingers and hands out of path of blade when using band saw in a

vertical position.

Hold work piece firmly against table.

Electric shock hazard. Be sure equipment is properly grounded.

Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the

risk of electric shock.

Ground fault circuit interrupters. If work area is not equipped with a permanently installed Ground

Fault Circuit Interrupter outlet (GFCI), use a plug-in GFCI between power tool or extension cord

and power receptacle.

Avoid body contact with grounded surfaces such as pipes, radiators, ranges, and refrigerators.

There is an increased risk of electric shock if your body is grounded.

Avoid accidental starting. Ensure the switch is in the off position before plugging tool into power

outlet.

In the event of a power failure, while a tool is being used, turn both the switches off to prevent

surprise starting when power is restored.

When moving the saw, ALWAYS have the head lowered to the horizontal position.

Turn power OFF before servicing.

Grounding

This machine must be grounded while in use to protect the operator from electrical shock. This

drill press is equipped with an electrical cord that has an equipment grounding conductor and a

grounding plug. The plug MUST be plugged into a matching receptacle that is properly installed

and grounded in accordance with ALL local codes and ordinances.

DO NOT MODIFY THE PROVIDED PLUG. If it will not fit the receptacle, have the proper

receptacle installed by a qualified electrician.

CHECK with a qualified electrician or service person if you do not completely understand the

grounding instructions, or if you are not sure the tool is properly grounded.

Grounded Tools: Tools with 3-Prong Plugs

Tools marked with Grounding Required have a 3-wire cord and 3-prong grounding plug. The plug

must be connected to a properly grounded outlet. If the tool should electrically malfunction or break

down, grounding provides a low resistance path to carry electricity away from the user, reducing the

risk of electric shock. (See Figure A.)

The grounding prong in the plug is connected through the green wire inside the cord to the grounding

system in the tool. The green wire in the cord must be the only wire connected to the tool’s grounding

system and must never be attached to an electrically live terminal.

Your tool must be plugged into an appropriate outlet, properly installed and grounded in accordance

with all codes and ordinances. The plug and outlet should look like those in the following illustration.

Double Insulated Tools: Tools with Two-Prong Plugs

Tools marked Double Insulated do not require grounding. They have a special double insulation

system which satisfies OSHA requirements and complies with the applicable standards of

Underwriters Laboratories, Inc., the Canadian Standard Association, and the National Electrical Code.

(See Figure B.)

Double insulated tools may be used in either of the 120 volt outlets shown in the following illustration.

Starting the Saw

Note: The coolant switch is integrated with the motor start switch. The coolant function is ON while the saw is operating, If you do not need the coolant function, turn the rocker switch on the coolant pump OFF.

A Stop button

B Start button

Never operate the saw without the blade guards in place to protect against personal injury.

1. Be sure the blade is not in contact with the work when the motor is started.

2. Start the motor, allow the saw to come to full speed, and then begin the cut by letting the head down slowly onto the work.

DO NOT DROP OR FORCE the cut. Let the weight of the saw head provide the cutting force.

3. The saw automatically shuts off at the end of the cut.

Blade Selection

An 8-tooth per inch, general-use blade is furnished with the saw. Additional blades in 4, 6, 8, and

10 tooth sizes are available.

The choice of blade pitch is governed by the thinness of the work to be cut: the thinner the work

piece, the more teeth advised. A minimum of three (3) teeth should engage the work piece at all

times for proper cutting. If the teeth of the blade are so far apart that they straddle the work,

severe damage to the workpiece and to the blade can result.

Changing the Blade

1. Ensure power is disconnected from saw.

2. Raise saw head to the highest position and open the blade guards (292S and 317S) using the hand wheels.

3. Remove the blade back cover (327).

4. Loosen the tension screw knob (218) sufficiently to allow the saw blade to slip off the wheels.

5. Install the new blade with teeth slanting toward the motor (see Blade Direction of Travel above) as follows:

a. Place the blade in between each of the guide bearings (293S/294S and 315S/316S).

b. Slip the blade around the drive wheel (264) with the left hand and hold in position.

c. Hold the blade taut against the drive wheel by pulling the blade upward with the right hand which is placed at the top of the blade.

d. Remove the left hand from drive wheel and place is at the top side of the blade to continue the upward pull on the blade.

e. Remove the right hand from the blade and adjust the position of the idler wheel (235S) to permit the left hand to slip the blade around the wheel using the thumb, index and little finger as guides.

f. Adjust the blade tension knob clockwise until it is just right enough so no blade slippage occurs. Do not tighten excessively.

6. Replace the blade back cover.

7. Place 2-3 drops of oil on the blade.

Blade Guide Bearing Adjustment

This is the most important adjustment on your saw. It is impossible to get satisfactory work from your saw if the blade guides are not properly adjusted. The blade guide bearings on your band saw are adjusted and power tested with several test cuts before leaving the factory to insure proper setting.

The need for adjustment should rarely occur if the saw is used properly. If the guides do get out of adjustment though, it is extremely important to readjust immediately. If improper adjustment in maintained, the blade will not cut straight, and if the situation is not corrected it will cause serious blade damage.

Because guide adjustment is a critical factor in the performance of your saw, it is always best to try a new blade to see if this will correct poor cutting before beginning to adjust the bearings. If a blade becomes dull on one side sooner than the other, for example, it will not cut straight. A blade simple change should correct this problem, the more difficult guide adjustment will not.

If a new blade does not correct the problem, check the blade guides for proper spacing. There should be from 000 (just touching) to 001” clearance between the blade and guide bearings. The inner guide bearing is fixed and cannot be adjusted. The outer guide bearing is mounted to an eccentric bushing and can be adjusted. To obtain this clearance adjust as follows, referencing the figures below:

1. Adjust the tension of the blade (A) until its back is lightly against the blade wheel.

2. Loosen the nut (E).

3. Turn the eccentric shaft (B) counterclockwise until the bearing (D) touches the saw blade then retighten the nut (E).

4. Loosen set screw (F) and move the blade vertically up or down until it lightly touches the back of the blade then retighten the set screw.

5. The carbide blade guides (L) can also be adjusted so they lightly touch the blade by loosening screws (M), adjusting the guides then retightening the screws.

6. Repeat steps 1 - 5 to adjust the other side's blade guide bearings (G).

If it is necessary to adjust the vise halves perpendicular to the blade, perform steps 7 – 9.

7. Loosen set screw (F).

8. Lower the cutting head frame, adjust the rear jaw vise (H) by loosening screw (I), position the vise with the blade using a scale then tighten the screw.

9. Loosen set screw (K), move the front vise (J) up against the rear jaw vise (H), then retighten the screw.

Blade Track Adjustment

1. Open the blade guard (327).

2. Remove the blade guide assemblies (top and bottom)(327)

3. Loosen the hex head screw in the tilting mechanism to a point where it is loose but snug (216).

4. With the machine running, adjust both the set crew and blade tension knob (218) simultaneously to keep constant tension on the blade. The set screw (264-1) and blade tension knob (218) are always turned in opposite directions, when one is turned clockwise the other is turned counterclockwise.

The blade is tracking properly when the back side just touches the shoulder of the wheel or a slight gap appears near the center line of the wheel. Care should be taken not to over-tighten the saw blade since this will give a false adjustment and limit the life of the blade.

5. Tighten the hex head screw in the tilting mechanism. IMPORTANT: Sometimes in trying to make this critical adjustment it is possible to cause the basic setting to be misaligned. Should this occur, proceed as follows:

a. Loosen the set screw (264-1) and back it out as far as it can go and still remain in the threaded hole.

b. Turn the hex head screw clockwise until it stops (do not tighten)(216).

c. Turn the set screw (264-1) clockwise until it bottoms out, then continue for half a turn and check the tracking by turning on the saw.

d. If further adjustment is required, go back to step 4.

6. Turn off power to the machine.

7. Replace the blade guide assemblies (327)--it may be necessary to loosen the blade tension slightly (216).

8. Adjust the vertical position of blade guide bearing assemblies so that the back side of the blade just touches the ball bearings.

9. Make a final run to check tracking. If required, touch up adjustment (See step 4)

10. Replace the blade guards.

Page 18 of 30

After Each Use

When you finished your work, clean the saw of debris and scraps of metal and spread a thin coat of oil on the surfaces that not painted to prevent rust.

Store the tool when it is not in use. Store it in a dry, secure place out of the reach of children. Inspect the tool for good working condition prior to storage and before re-use.

Maintenance

Maintain the saw by adopting a program of conscientious repair and maintenance in accordance with the following recommended procedures. It is recommended that the general condition of any tool be examined before it is used. Keep your tool in good repair. Keep all cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control. Keep handles dry, clean, and free from oil and grease.

Put both the power switches in the locked or off position before making any adjustments or changing

parts. Such preventive safety measures reduce the risk of starting the saw accidentally.

Daily Maintenance (by operator)

Fill (top off) the gear box with lubricant every day before starting machine.

If the temperature of the spindle causes over-heating or strange noises, stop the machine

immediately to check it for accurate functionality.

Weekly Maintenance

Clean and coat the leading screw with oil.

Check to see if the sliding surfaces and rotating parts lack lubricant. If needed, lubricate any parts

needing it.

Monthly Maintenance

Check all the bolts nuts and fastening fixtures and tighten any that are loose.

Lubricate the bearings, worm, and worm shaft to avoid wear on them.

Yearly Maintenance

Readjust the table to horizontal position to maintain cutting accuracy.

Check the electric cord, plugs, and switches at least once a year.

Change the lubricant in the gear box (see Lubrication below).

Lubrication

Lubricate the following components using SAE-30 oil as noted.

Ball-bearing: none needed

Driven pulley bearing: 6-8 drops a week

Vise lead screw: as needed

The gear box drive gears run in an oil bath and do not require a lubricant change more often than once a year, unless the lubricant is accidentally contaminated or a leak occurs because of

Page 19 of 30

improper replacement of the gear box cover. During the first few days of operation, the worm gear drive will run hot. Unless the temperature exceeds 200ºF, there is no cause for alarm.

The following lubricants may be used in the gear box:

Atlantic Refinery Co, Mogul Cyl. Oil
