To operate this or any power tool safely and effi-ciently, it is essential to become as familiar with itas possible. The time you invest before you beginto use your Model G1071 will be time well spent.

DO NOT operate this machine until you arecompletely familiar with the contents of thismanual. Serious personal injury may occurif used without proper training.

I. INTRODUCTION


II. SAFETY RULES FOR ALL TOOLS

The Model G1071 is inherently dangerous. Using the tool with respect and caution willlessen the possibility of mechanical damage or operator injury. If normal safety precau-tions are overlooked or ignored, serious personal injury may occur.

This machine is specifically designed for wood sanding operations. Modifications orimproper use of this tool can result in damage to the machine and possible operator injury,and will void all warranties. If you are confused about any aspect of this machine, DO NOTuse it until you have resolved any questions you might have. The following are importantsafety rules for all tools:

1. KNOW YOUR POWER TOOL. Readthe owner’s manual carefully. Learn thetool’s applications and limitations, aswell as its hazards.

2. KEEP ALL GUARDS IN PLACE and inworking order.

3. GROUND ALL TOOLS. If an adapter isused to accommodate a two-prongreceptacle, the adapter plug must beattached to a known ground. Neverremove the grounding prong.

4. REMOVE ADJUSTING KEYS ANDWRENCHES. Make it a habit to checkthat keys and adjusting wrenches areremoved from the machine before turn-ing it on.

5. KEEP WORK AREA CLEAN.Cluttered areas and benches inviteaccidents.

6. AVOID DANGEROUS ENVIRON-MENTS. Do not use power tools indamp or wet locations or expose themto rain. Keep your work area well light-ed.

7. KEEP CHILDREN AND VISITORSAWAY. All children and visitors shouldbe kept a safe distance away from yourwork area. Serious injuries could occur.

8. MAKE WORKSHOP CHILD-PROOFwith padlocks, master switches, or byremoving starter keys.

9. DO NOT FORCE TOOL. Tools workbetter and more safely when they areallowed to work at their own speed.

10. USE THE RIGHT TOOL. Do not use atool or an attachment to do a job that itwas not intended to perform.

11. WEAR PROPER APPAREL. Do notwear loose clothing, gloves, neckties, orjewelry that might get caught in movingparts. Non-slip footwear is also recom-mended. Wear a hat or other protectivehead wear if your hair is long.

12. USE SAFETY GLASSES AND EARPROTECTION. Also use a dust mask ifthe sanding operation is dusty.

13. SECURE YOUR WORK. Use clamps ora fixture to hold your work. It is saferthan using your hands and frees upboth hands for operating the tool.

14. DO NOT OVERREACH. Keep properfooting and balance at all times.

15. MAINTAIN TOOLS IN TOP CONDI-TION. Keep tools sharp and clean forbest and safest performance. Followinstructions for lubricating and changingaccessories.


II. SAFETY RULES FOR ALL TOOLS - CONT’D

16. DISCONNECT TOOLS FROMPOWER before servicing and whenchanging accessories such as sandingsleeves.

17. USE ONLY RECOMMENDEDACCESSORIES. Consult the currentcatalog for recommended accessories.Using improper accessories may behazardous.

18. AVOID ACCIDENTAL STARTING.Make sure the switch is in the “OFF”position before plugging in the cord.

19. NEVER STAND OR LEAN ON TOOL.Serious injury could occur if the tool istipped or if the spindle is accidentallycontacted while running.

20. CHECK DAMAGED PARTS. Beforefurther use of the tool, any part or guardthat is damaged should be promptlyrepaired or replaced. Do not operatethe machine until you are certain that itis in perfect running condition. Failureto follow this precaution could result infurther mechanical damage and opera-tor injury.

21. ALWAYS FEED YOUR WORKAGAINST THE DIRECTION OF SPIN-DLE TRAVEL. Workpieces fed in thesame direction as the spindle travelcould be forced out of your control.

22. NEVER LEAVE THE TOOL RUNNINGUNATTENDED - TURN POWER OFF.Do not leave the tool unattended until itcomes to a full stop.

23. DO NOT OPERATE THE TOOLUNDER THE INFLUENCE OFDRUGS, ALCOHOL, OR ANY MED-ICATION. Never operate machinerywhen overly fatigued.

24. DO NOT WORK IN HASTE or operatemachine if you are mentally or physi-cally fatigued.

25. IF THERE IS SOMETHING YOU DONOT KNOW OR UNDERSTAND, DONOT OPERATE MACHINE! Ask forhelp first. Confusion can be dangerous.

26. BAD HABITS ARE DANGEROUS.Review all safety procedures often.

These safety rules, while expansive,may not cover every situation in a wood-shop. Please consider your unique con-ditions when setting up and using yoursander.


III. ELECTRICAL SERVICE REQUIREMENTS

C. GENERAL INFORMATIONIf converting to 220V, it will be necessary toconnect a plug that matches your 220V recep-tacle. If you will be installing a new receptacleand plug, we recommend either of the follow-ing styles.

EXTENSION CORDS: If used, extensioncords must be rated hard service – grade S –or better. Conductor size must be 12 AWG forcords up to 50 feet in length. Your extensioncord must also contain a ground wire and plugpin. Repair or replace extension cords if theybecome damaged.

A. CIRCUIT LOADINGThe G1071 motor will safely draw about 14amps at 110V (7A @ 220V) under load. If youoperate the sander on any circuit that isalready close to its capacity, it might blow afuse or trip a circuit breaker. However, if anunusual load does not exist, and power fail-ure still occurs, have the circuit inspected bya qualified electrician.

CIRCUIT BREAKERS/FUSES: A 15 amp cir-cuit breaker or fuse should be used for a110V undedicated circuit. A 10 amp circuitbreaker or fuse should be used for a 220Vundedicated circuit. The general rule is to usethe lightest breaker or fuse that will holdunder regular loads. Circuit breakers or fusesthat are rated higher may not adequately pro-tect the motor.

B. GROUNDINGThis machine must be electrically ground-ed. We have furnished the sander with a cordsuitable for use with a grounded, domestic110V circuit.

Figure 1 220V plug/receptacles.

In this section we have covered some basicelectrical requirements for the safe opera-tion of your sander. Keep in mind that theserequirements are not necessarily compre-hensive. Further, you must be sure that yourparticular electrical configuration complieswith local and state codes. The best way toensure compliance is to check with yourlocal municipality or licensed electrician.

Please verify that any circuit you intend touse is actually grounded. If the circuit is notgrounded, it will be necessary to run a sep-arate 12 AWG copper grounding wire fromthe machine frame to a grounding terminalin your electric service panel.

If you are not sure about wiring yoursander, don’t take chances: consult theservice department or an electrician.

The Model G1071 has a 1 HP motor thatoperates at 110V/220V. It has been pre-wiredfor 110V, single phase operation. Please con-sult the wiring diagram for information aboutconversion to 220V.


The sander is shipped from the factory in acarefully-packed carton. If you find themachine to be damaged after you’ve signedfor delivery and the truck and driver arealready gone, you will need to file a freightclaim with the carrier. Save the containers andall packing materials for inspection by the car-rier or its agent. Without the packing materi-als, filing a freight claim can be difficult. If youneed advice regarding this situation, pleasecontact us immediately.

When you are completely satisfied with thecondition of your shipment, you should inven-tory its parts.

V. UNPACKING

A. FLOOR LOAD

Your G1071 Sander represents a large weightload in a small footprint. Most commercialfloors are suitable for the Model G1071. Someresidential floors may require additional buildup to support both machine and operator.

B. WORKING CLEARANCES

Working clearances can be thought of as thedistances between machines and obstaclesthat allow safe operation of every machinewithout limitation. Consider existing and antic-ipated machine needs, size of material to beprocessed through each machine, and spacefor auxiliary stands and/or work tables. Alsoconsider the relative position of each machineto one another for efficient material handling.Be sure to allow yourself sufficient room tosafely run your machines IN ANY FORESEE-ABLE OPERATION.

C. LIGHTING AND OUTLETS

Lighting should be bright enough to eliminateshadows and prevent eye strain. Electrical cir-cuits should be dedicated or large enough tohandle combined motor amperage loads.Outlets should be located near each machineso power or extension cords do not obstructhigh-traffic areas. Be sure to observe localelectrical codes for proper installation of newlighting, outlets, or circuits.

IV. SITE PLANNING

The G1071 is a very heavy machine (300lbs. shipping weight). DO NOT over-exert yourself while unpacking or mov-ing your machine – get assistance. Inthe event that your sander must bemoved up or down a flight of stairs, besure that the stairs are capable of sup-porting the combined weight of themachine and the people moving it.


Take a quick inventory of the parts and putthem aside for later assembly.

Since the majority of the spindle sander ispre-assembled at the factory, there aren’t a lotof items to inventory. You should have the fol-lowing items:

• Spindle Sander Unit• Sanding Spindles (10)• Table Inserts (3)• Spindle Wrenches (2)• Allen® Wrench (1)

VI. PIECE INVENTORY

The table is coated with a waxy oil to protect itfrom corrosion during shipment. Remove theprotective coating with common paint thinner(mineral spirits) and paper towels.

VII. CLEAN UP

Follow the safety rules listed belowwhen working with solvents.

1. Read and follow all directions andwarnings on the solvent label.

2. Work only in a well ventilated area.

3. Do not work near any type of openflame (e.g., pilot lights, keroseneheaters, wood stoves and so on).

4. DO NOT smoke while working withflammable material.

5. Paper towels from the cleaningprocess are extremely combustible.Dispose of waste towels so they donot create a fire hazard.

Do not use gasoline or other petroleum-based solvents because of their extremelylow flash points. Do not use acetone orchlorine-based solvents – if you happen tosplash some onto painted surfaces, you’lldamage the sander’s finish.

All die-cut metal parts have a sharp edge(called “flashing”) on them after they areformed. This is removed at the factory.Sometimes, though, a bit of flashingmight escape inspection. Please exam-ine the edges of all die-cut metal partsbefore handling them.


The Model G1071 comes equipped with awrench for spindle removal. It should be keptclose to the machine for easy access. TheModel G1071 features two spindle rackswhich hold spindles in a handy location whenthey are not in use. The spindles are held inplace on the racks by hex nuts.

To install sanding spindles on the ModelG1071:

1. Pick out the appropriate spindle andremove it from the rack.

2. Drop the threaded end of the spindle intothe spindle hole. Make sure the holeand the shaft are lightly greased.

3. Screw the spindle in by hand. Sandingaction will further tighten the spindle so itis unnecessary to over tighten. Figure 2.

4. The spindle is now mounted.

To remove the sanding spindle:

1. Use your spindle wrench provided withthe machine to hold the jam nuts abovethe spindle cover while loosening thespindle retainer nut with another wrench.

2. Unscrew the sanding spindle and return itto the storage rack.

Assembly of the G1071 is straightforward.We have organized the assembly processinto steps. Please follow them in sequence.Review the parts diagrams and lists frequent-ly to become familiar with all of the partsbefore you begin.

A. SPINDLES

Spindle size should be based on needs of theproject. Straight or gently curved surfaces willbe best suited to the largest of the spindles.Tighter, more-intricate workpieces will requirethe smaller spindles. Avoid the temptation toleave the same spindle on until its sandingsleeve wears out. You’ll get much more lifefrom each of your sanding spindles if they areused only for specific jobs.

B. LUBRICATION

Check the gear oil level using the dipstickwhich is located at the front of the machinejust below the table. See Figure 7. This oillevel should indicate full before the intitial runof the machine. See Maintenance Section formore details on lubrication of the SpindleSander.


2. Remove the sleeve from the spindle. Ifyou have worn the sleeve out on one end,you can extend the life of the sleeve byflipping it over and refitting it on the spin-dle. If the entire sleeve is worn out,replace with a new sleeve of the correctdiameter.

3. Re-tighten the hex nut at the top of thespindle (or setscrews at the base) andbegin using again.

E. DUST COLLECTION

The Model G1071 is capable of creating alarge amount of dust while in use. If you havea dust collection system in your shop, youshould create a duct to service the spindlesander. The exhaust hood is designed toaccommodate 4" flexible collection hose. Notethe location of the Dust Port in Figure 3.

If a dust collection system is not available, youmight consider purchasing adapters that willenable you to use your shop vacuum to workas a portable dust collection tool. The Grizzlycatalog provides a wide variety of dust collec-tors and dust collection accessories. See thelatest issue of the Grizzly catalog for moreinformation.

VIII. ASSEMBLY - CONT’D

C. TABLE INSERTS

The three inserts included with the ModelG1071 are sized to provide free sanding spin-dle movement while minimizing the gapbetween the abrasive surface and the tabletop. The holes in the inserts are shaped toallow the sanding spindles to rotate freelyeven when the table is angled to its maximum45° pitch.

Place the insert with the smallest diameterwhich allows free movement of the spindleover the top of the spindle and lower it into thehole in the table top. The insert is fitted withpins which only allow it to fit securely in oneposition on the table. That position allows thetable to tilt without impeding the movement ofthe spindle.

Each insert is fitted with setscrews whichenable you to adjust the insert’s height. Usethose setscrews to adjust the insert to matchthe height of the tabletop. Smooth movementof your workpiece is essential for propersander operation. Make sure your inserts arealigned as closely to the table as possible.

D. SANDING SLEEVES

Grizzly offers sleeves in 60, 80, 100, 120 and150 grit. Please refer to the Grizzly catalogfor ordering information.

To replace the sleeves:

1. Loosen the hex nut at the top of thesanding spindle (spindles 5/8" and small-er have setscrews at their bases thatsecure the sleeves to the spindle).


The Angle Adjustment Levers enable thetable top to be tilted up to 45° to the front and20° to the rear. Figure 3. Both levers must bereleased to allow the table to tilt. The leversare located under the table on both the leftand right sides of the sander. The angle indi-cator shows the degree of pitch.

To calibrate the angle indicator:

1. Use a quality machinist’s square andbring the table perpendicular (90°) to thespindle. Move the square around thesanding spindle to ensure that the tableis square in all directions. Figure 4.

2. Lock the levers down when your table issquare to the sanding spindle. You cannow calibrate the angle indicator arrow(shown in Figure 3) by loosening itsretaining screw and turning the arrowuntil it points directly to “zero” on theangle guide.

There is a positive stop bolt (#54) that, whenadjusted correctly, allows you to return thetable square to the spindle with little effort.The positive stop bolt is a long bolt locatedbelow the table.

To adjust the positive stop bolt:

1. Loosen the jam nut on the positive stopbolt.

2. With the table square to the spindle andtightened securely, adjust the positivestop bolt so it just touches the table.

3. Re-tighten the jam nut.

4. If angling the table over the dust port, firstloosen the jam nut and then remove thestop bolt completely. You can then tilt thetable back to 20°. Don’t forget to re-cali-brate the stop bolt when you put it backin.

X. SANDER SAFETY

9. BE SURE TO OBSERVE ELECTRI-CAL REQUIREMENTS SUCH ASFUSE SIZING, WIRE SIZING, ANDGROUNDING.

10. ENSURE THAT THE SWITCH IS INTHE OFF POSITION BEFORE PLUG-GING THE MACHINE INTO ITSPOWER SOURCE.

11. DO NOT stand directly in line with sand-ing accessories when turning themachine on.

12. DO NOT force the workpiece againstthe spindle during operation. Firmlygrasp the workpiece in both hands andease it against the spindle using lightpressure.

13. DO NOT wear loose clothing whileoperating this machine. Roll up sleevesor button sleeves at the cuff.

14. DO NOT place hands near, or in contactwith sanding sleeve during operation.

15. PERFORM MACHINE INSPECTIONSand maintenance service promptlywhen called for.

16. ANY PROBLEM that is concerned at allwith any moving parts or accessoriesmust be investigated and corrected withthe power disconnected, and aftereverything has come to a completestop.

It cannot be assumed that additional safetymeasures are not needed under particular orexceptional circumstances or conditions.Consider safety at all times.

1. MAINTAIN A SECURE GRIP ON THEWORKPIECE. The spindle rotates atmore than 1700 R.P.M. If control is lost,the workpiece could be shot from themachine at extreme speed.

2. CREATE A SAFETY ZONE AROUNDTHE SANDING SURFACE. If you can'tcontrol your workpiece with your handsat least 6" away from the sandingsleeve, you should create a jig or otherdevice to hold the workpiece safely.

3. DON’T OPERATE THE SPINDLESANDER if the proper insert is not inplace.

4. REPLACE SLEEVES WHEN WORNOR DAMAGED. A torn or damagedsleeve could be unexpectedly expelledfrom the machine if not replaced.

5. KEEP YOUR WORKPIECE SOLIDLYON THE SANDER TABLE. A well-secured workpiece is less likely to losecontrol during sanding operations.

6. INSPECT MATERIALS FORDEFECTS. Knots and splinters canshoot from the machine with greatforce. Make sure defective materialsare not used on the spindle sander.Foreign objects such as nails and sta-ples should also be removed beforesanding.

7. TURN OFF THE SANDER WHEN NOTIN USE. Never leave a machine run-ning unattended.

8. ALWAYS wear eye protection and arespirator.

When the guidelines illustrated in this manualare followed, the Model G1071 is a safe andenjoyable tool to use, even for the novice

woodworker. Please follow these specificsafety rules before beginning to use yourmachine.


XI. OPERATIONS

BEFORE STARTING YOUR SANDER FORTHE FIRST TIME, CHECK OIL LEVEL ANDGREASE POINTS. See MaintenanceSection for more information. Check at leastmonthly thereafter.

Also before starting the sander, be sure youhave followed all the guidelines for set up. Ifeverything checks out, push the “ON” buttonand let the machine run. After a few moments,turn the machine off and use a piece of scrapwood to get a feel for the machine. As wenoted in the sander safety guidelines, youshould be sure that any wood you use is freeof defects and foreign objects.

The Model G1071 is designed to give cleanfinished edges to your work, so when pre-cut-ting with your jigsaw or bandsaw, make ahabit of cutting about 1/16" outside the edges ofyour finished workpiece. Mark a clean linewith a pencil or scribe along the desired out-side edge of your workpiece, or in this case,your test piece.

When you’ve marked your material, turn theModel G1071 on again. Let it reach its work-ing speed and slide the test piece against thesanding surface. The sander requires littlepressure between the spindle and workpiece.

Move your test piece against the rotation ofthe sanding spindle. To achieve the bestresults, remove excess material in severalpasses. Your results will be more even andyou’ll have less chance of accidentally remov-ing too much material or burning your work.Using this method will also decrease wear onyour sanding sleeves.

Now, try bevel sanding. Turn off the machineand tilt the table to the angle of bevel youdesire. Spin the sanding spindle by hand toensure there is free movement. When bevel-ing, always place your scribe marks at theoutside (longest) edge of your bevel, so youcan see the marks from above. After restart-ing the machine, gently press the test pieceagainst the sanding spindle and take severalpasses until your scribe lines are reached.

Placing a 1" or thicker false table over thesander’s table will offer several advantages. Itwill raise the working surface up and makebeveled sanding with the larger spindles eas-ier. It will bring your working surface closer tothe spindle for better control of smaller work-pieces. It will allow you to more fully utilize theentire length of your sanding sleeves, espe-cially when working with thin workpieces. Thefalse table can be moved around on thesander’s table and secured by C-clamps.

Figure 6 Angled or bevel sanding (45°).Figure 5 Flat sanding.


XII. MAINTENANCE

Your Model G1071 Spindle Sander requiresvery little maintenance. Cleaning will increasethe machine’s durability and efficiency byremoving grime which can gum up movingparts. If you find that the machine sands lessefficiently than usual, inspect the sandingsleeves and clean with a gum rubber beltcleaner (available in the Grizzly catalog) orreplace them as needed. An occasional appli-cation of good quality automotive paste wax(one which does not contain silicone or othersynthetics) will keep the sander table andother bare metal parts from rusting and pit-ting.

A. LUBRICATION

Bearings:The Model G1071 features factory-sealedbearings. A sealed bearing requires no lubri-cation during its lifetime.

Should a bearing fail, your spindle sander willprobably develop a noticeable rumble, whichwill increase when the machine is put underload. Bearings must be replaced when thisoccurs. Bearings are standard sizes and canbe replaced through Grizzly.

Gear Oil:Gear oil should be changed yearly (if sanderis used daily) with a high-quality 90 Wt. gearoil. The oil cap w/dipstick is located at thefront of the machine, just below the table.Figure 7. The drain plug is at the base of thegear housing and is accessed through thedoor on the cabinet. The sander takes approx.2.8 quarts.

In addition to yearly replacement, the oil levelshould be checked at least monthly and oiladded when indicated by the dipstick.

The sander is equipped with a breather valveto allow heated vapors to escape from the oilhousing. DO NOT TRY TO ADJUST THE

BREATHER VALVE WITHOUT FIRST CON-SULTING THE SERVICE DEPARTMENT!

Trunnions:The trunnions should be lubricated with medi-um grease as needed to make table adjust-ment easier.

B. SANDING SLEEVE MAINTENANCE

Sanding sleeves should be inspected periodi-cally for wear or damage. Damaged sleevesshould be replaced before further use. Do notallow the rubber portion of the spindle to comein contact with workpieces during operation.Damage to the rubber will occur.
