When machine is not being used, disconnect power, remove switch keys, or lock-out machine to prevent unauthorized use—especially around children. Make your workshop kid proof!

DANGEROUS ENVIRONMENTS. Do not use machinery in areas that are wet, cluttered, or have poor lighting. Operating machinery in these areas greatly increases the risk of accidents and injury.

MENTAL ALERTNESS REQUIRED. Full mental alertness is required for safe operation of machinery. Never operate under the influence of drugs or alcohol, when tired, or when distracted.

ELECTRICAL EQUIPMENT INJURY RISKS. You can be shocked, burned, or killed by touching live electrical components or improperly grounded machinery. To reduce this risk, only allow qualified service personnel to do electrical installation or repair work, and always disconnect power before accessing or exposing electrical equipment.

DISCONNECT POWER FIRST. Always disconnect machine from power supply BEFORE making adjustments, changing tooling, or servicing machine. This prevents an injury risk from unintended startup or contact with live electrical components.

EYE PROTECTION. Always wear ANSI-approved safety glasses or a face shield when operating or observing machinery to reduce the risk of eye injury or blindness from flying particles. Everyday eyeglasses are NOT approved safety glasses.

WARNING

WEARING PROPER APPAREL. Do not wear loose clothing, gloves, neckties, or jewelry that can become entangled in moving parts. Always tie back or cover long hair. Wear non-slip footwear to reduce risk of slipping and losing control or accidentally contacting cutting tool or moving parts.

HAZARDOUS DUST. Dust created by machinery operations may cause cancer, birth defects, or long-term respiratory damage. Be aware of dust hazards associated with each workpiece material. Always wear a NIOSH-approved respirator to reduce your risk.

HEARING PROTECTION. Always wear hearing protection when operating or observing loud machinery. Extended exposure to this noise without hearing protection can cause permanent hearing loss.

REMOVE ADJUSTING TOOLS. Tools left on machinery can become dangerous projectiles upon startup. Never leave chuck keys, wrenches, or any other tools on machine. Always verify removal before starting!

USE CORRECT TOOL FOR THE JOB. Only use this tool for its intended purpose—do not force it or an attachment to do a job for which it was not designed. Never make unapproved modifications—modifying tool or using it differently than intended may result in malfunction or mechanical failure that can lead to personal injury or death!

AWKWARD POSITIONS. Keep proper footing and balance at all times when operating machine. Do not overreach! Avoid awkward hand positions that make workpiece control difficult or increase the risk of accidental injury.

CHILDREN & BYSTANDERS. Keep children and bystanders at a safe distance from the work area. Stop using machine if they become a distraction.

GUARDS & COVERS. Guards and covers reduce accidental contact with moving parts or flying debris. Make sure they are properly installed, undamaged, and working correctly BEFORE operating machine.

FORCING MACHINERY. Do not force machine. It will do the job safer and better at the rate for which it was designed.

Additional Safety for Spindle Sanders

⚠WARNING

Serious injury or death can occur from fingers, clothing, jewelry or hair getting entangled in rotating spindle or other moving components. Abrasion injuries can occur from touching rotating sanding drum with bare skin. Workpieces thrown by drum can strike operator or bystanders with moderate force, causing impact injuries. Long-term respiratory damage can occur from using sander without proper use of a respirator. To reduce the risk of these hazards, operator and bystanders MUST completely heed the hazards and warnings below.

HAND PLACEMENT. Rotating sanding drums can remove a large amount of flesh in a few seconds. Always keep hands away from drum during operation. Never touch moving drum on purpose. Use a brush to clean table of sawdust and chips.

FEEDING WORKPIECE. Forcefully jamming workpiece into sanding surface could cause workpiece to eject back at operator or damage machine. Always allow spindle to reach full speed. Firmly hold workpiece with both hands and ease it against spindle using light pressure.

DRUM DIRECTION. Feeding workpiece incorrectly can cause it to be thrown from machine, allowing your hands to slip into the rotating drum or striking yourself or bystanders. To reduce these risks, feed workpiece against direction of rotation, and never sand tapered or pointed stock with point facing feed direction.

SANDING SLEEVE CONDITION. Worn or damaged sanding sleeves can tear apart and become entangled in spindle, resulting in subsequent injuries from operator loss of workpiece control. Replace worn or damaged sanding sleeves promptly.

SANDING DUST. Sanding creates large amounts of dust and flying chips that can lead to eye injury or serious respiratory illness. Reduce your risk by always wearing approved eye and respiratory protection when using sander. Never operate without adequate dust collection system in place and running. However, dust collection is not a substitute for using a respirator.

AVOIDING ENTANGLEMENT. DO NOT wear loose clothing, gloves, or jewelry, and tie back long hair. Keep all guards in place and secure.

WORKPIECE INSPECTION. Nails, staples, knots, or other imperfections in workpiece can be dislodged and thrown from sander at high rate of speed into operator or bystanders, or cause damage to sanding sleeves or drum. Never sand stock that has embedded foreign objects or questionable imperfections.

TABLE INSERTS. A pinch point for fingers and workpieces exists in the gap between table and oscillating drum. Always use table insert that fits closest to diameter of installed drum to keep this gap as small as possible and reduce risk of injury.

POWER DISCONNECT. An accidental startup while changing sleeves can result in entanglement or abrasion injuries. Always disconnect machine from power source before changing sanding sleeve to avoid this risk.

WORKPIECE INTEGRITY. Sanding fragile workpieces can result in loss of control, resulting in entanglement, impact injuries, or damage to the sanding sleeve or drum. Only sand solid workpieces that can withstand power sanding forces. Make sure shape of workpiece is properly supported; avoid sanding workpieces without flat bottom surfaces unless some type of jig is used to maintain support and control when sanding force is applied.

SECTION 2: POWER SUPPLY

Availability

Before installing the machine, consider the availability and proximity of the required power supply circuit. If an existing circuit does not meet the requirements for this machine, a new circuit must be installed. To minimize the risk of electrocution, fire, or equipment damage, installation work and electrical wiring must be done by an electrician or qualified service personnel in accordance with all applicable codes and standards.

Full-Load Current Rating

The full-load current rating is the amperage a machine draws at 100% of the rated output power. On machines with multiple motors, this is the amperage drawn by the largest motor or sum of all motors and electrical devices that might operate at one time during normal operations.

G1071 Full-Load Current Rating at 120V ..12A

• G1071 Full-Load Current Rating at 240V ........ 6A G1071Z Full-Load Current Rating at 120V...15.5A

The full-load current is not the maximum amount of amps that the machine will draw. If the machine is overloaded, it will draw additional amps beyond the full-load rating.

If the machine is overloaded for a sufficient length of time, damage, overheating, or fire may result—especially if connected to an undersized circuit. To reduce the risk of these hazards, avoid overloading the machine during operation and make sure it is connected to a power supply circuit that meets the specified circuit requirements.

Circuit Information

A power supply circuit includes all electrical equipment between the breaker box or fuse panel in the building and the machine. The power supply circuit used for this machine must be sized to safely handle the full-load current drawn from the machine for an extended period of time. (If this machine is connected to a circuit protected by fuses, use a time delay fuse marked D.)

CAUTION

For your own safety and protection of property, consult an electrician if you are unsure about wiring practices or electrical codes in your area.

Note: Circuit requirements in this manual apply to a dedicated circuit—where only one machine will be running on the circuit at a time. If machine will be connected to a shared circuit where multiple machines may be running at the same time, consult an electrician or qualified service personnel to ensure circuit is properly sized for safe operation.

Circuit Requirements for 120V

This machine is prewired to operate on a power supply circuit that has a verified ground and meets the following requirements:

• Nominal Voltage ........ 110V, 115V, 120V
• Cycle ........ 60 Hz

• Nominal Voltage ........ 208V, 220V, 230V, 240V
• Cycle ........ 60 Hz
• Phase ........ Single-Phase
• Power Supply Circuit ........ 15 Amps
• Plug/Receptacle ........ NEMA 6-15

Grounding Requirements for 120V

This machine MUST be grounded. In the event of certain malfunctions or breakdowns, grounding reduces the risk of electric shock by providing a path of least resistance for electric current.

For 120V operation: This machine is equipped with a power cord that has an equipment-grounding wire and a grounding plug (see following figure). The plug must only be inserted into a matching receptacle (outlet) that is properly installed and grounded in accordance with all local codes and ordinances.

Figure 5. Typical 5-15 plug and receptacle.

CAUTION

SHOCK HAZARD!

Two-prong outlets do not meet the grounding requirements for this machine. Do not modify or use an adapter on the plug provided—if it will not fit the outlet, have a qualified electrician install the proper outlet with a verified ground.

Model G1071

Grounding Requirements for 240V

For 240V operation: The plug specified under "Circuit Requirements for 240V" on the previous page has a grounding prong that must be attached to the equipment-grounding wire on the included power cord. The plug must only be inserted into a matching receptacle (see following figure) that is properly installed and grounded in accordance with all local codes and ordinances.

Figure 6. Typical 6-15 plug and receptacle.

Improper connection of the equipment-grounding wire can result in a risk of electric shock. The wire with green insulation (with or without yellow stripes) is the equipment-grounding wire. If repair or replacement of the power cord or plug is necessary, do not connect the equipment-grounding wire to a live (current carrying) terminal.

Check with a qualified electrician or service personnel if you do not understand these grounding requirements, or if you are in doubt about whether the machine is properly grounded. If you ever notice that a cord or plug is damaged or worn, disconnect it from power, and immediately replace it with a new one.

Extension Cords

We do not recommend using an extension cord with this machine. If you must use an extension cord, only use it if absolutely necessary and only on a temporary basis.

Extension cords cause voltage drop, which can damage electrical components and shorten motor life. Voltage drop increases as the extension cord size gets longer and the gauge size gets smaller (higher gauge numbers indicate smaller sizes).

Any extension cord used with this machine must be in good condition and contain a ground wire and matching plug/receptacle. Additionally, it must meet the following size requirements:

• G1071 Minimum Gauge Size ........ 14 AWG
• G1071Z Minimum Gauge Size ........ 12 AWG
• Maximum Length (Shorter is Better) ........ 50 ft.

Converting to 240V (G1071 Only)

The voltage conversion MUST be performed by an electrician or qualified service personnel.

The voltage conversion procedure consists of rewiring the motor and installing the correct plug. A wiring diagram is provided on Page 38 for your reference.

IMPORTANT: If the diagram included on the motor conflicts with the one on Page 38, the motor may have changed since the manual was printed. Use the diagram provided on the motor junction box instead.

Items Needed

• Phillips Head Screwdriver #2 ........ 1
• Electrical Tape ........ As Needed
• Wire Nut (16 AWG x 3) ........ 1
• 6-15 Plug ........ 1

Cleanup

The unpainted surfaces of your machine are coated with a heavy-duty rust preventative that prevents corrosion during shipment and storage. This rust preventative works extremely well, but it will take a little time to clean.

Be patient and do a thorough job cleaning your machine. The time you spend doing this now will give you a better appreciation for the proper care of your machine's unpainted surfaces.

There are many ways to remove this rust preventative, but the following steps work well in a wide variety of situations. Always follow the manufacturer's instructions with any cleaning product you use and make sure you work in a well-ventilated area to minimize exposure to toxic fumes.

Before cleaning, gather the following:

• Disposable rags
• Cleaner/degreaser (WD•40 works well)
• Safety glasses & disposable gloves
• Plastic paint scraper (optional)

Basic steps for removing rust preventative:

1. Put on safety glasses.
2. Coat the rust preventative with a liberal amount of cleaner/degreaser, then let it soak for 5–10 minutes.
3. Wipe off the surfaces. If your cleaner/degreaser is effective, the rust preventative will wipe off easily. If you have a plastic paint scraper, scrape off as much as you can first, then wipe off the rest with the rag.
4. Repeat Steps 2–3 as necessary until clean, then coat all unpainted surfaces with a quality metal protectant to prevent rust.

WARNING Gasoline and petroleum products have low flash points and can explode or cause fire if used to clean machinery. Avoid using these products to clean machinery.

CAUTION Many cleaning solvents are toxic if inhaled. Only work in a well-ventilated area.

NOTICE Avoid harsh solvents like acetone or brake parts cleaner that may damage painted surfaces. Always test on a small, inconspicuous location first.

Site Considerations

Weight Load

Refer to the Machine Data Sheet for the weight of your machine. Make sure that the surface upon which the machine is placed will bear the weight of the machine, additional equipment that may be installed on the machine, and the heaviest workpiece that will be used. Additionally, consider the weight of the operator and any dynamic loading that may occur when operating the machine.

Space Allocation

Consider the largest size of workpiece that will be processed through this machine and provide enough space around the machine for adequate operator material handling or the installation of auxiliary equipment. With permanent installations, leave enough space around the machine to open or remove doors/covers as required by the maintenance and service described in this manual. See below for required space allocation.

Children or untrained people may be seriously injured by this machine. Only install in an access restricted location.

Physical Environment

The physical environment where the machine is operated is important for safe operation and longevity of machine components. For best results, operate this machine in a dry environment that is free from excessive moisture, hazardous chemicals, airborne abrasives, or extreme conditions. Extreme conditions for this type of machinery are generally those where the ambient temperature range exceeds 41°–104°F; the relative humidity range exceeds 20%–95% (non-condensing); or the environment is subject to vibration, shocks, or bumps.

Electrical Installation

Place this machine near an existing power source. Make sure all power cords are protected from traffic, material handling, moisture, chemicals, or other hazards. Make sure to leave enough space around machine to disconnect power supply or apply a lockout/tagout device, if required.

Lighting

Lighting around the machine must be adequate enough that operations can be performed safely. Shadows, glare, or strobe effects that may distract or impede the operator must be eliminated.

Figure 12. Minimum working clearances.

1. Secure dust chute to trunnion assembly with pre-installed hex bolts, lock washers, and hex nuts (see Figure 13).

Figure 13. Dust chute installed.

2. Loosen both table lock levers (see Figure 14) and tilt table to 45°, then tighten levers.

3. Thread 3/8"-16 hex nut (jam nut) onto 3/8"-16 x 6-1/2" hex bolt (stop bolt), then thread bolt into sander base, as shown in Figure 14.

Figure 14. Table stop bolt installed.

4. Loosen table lock levers and lower table to rest on stop bolt.

5. Holding square flat against table, adjust table stop bolt until table surface is square to spindle surface (see Figure 15).

Note: To achieve table square to spindle, it may be necessary to thread table stop bolt further into base.

Figure 15. Checking table for square.

6. Move square to various points around table to ensure table is square to spindle on all sides. Adjust stop bolt as necessary until table rests on bolt and is square with spindle, then tighten table lock levers.

7. With stop bolt head against bottom of table, tighten jam nut against sander base (see Figure 16).

Figure 16. Table stop bolt adjusted to stop table at 0°.

8. Loosen Phillips head screw securing scale pointer (see Figure 17) and adjust pointer to 0°, then tighten screw.

Figure 17. Scale components.

9. Thread (4) 1/4"-20 x 5/8" set screws into threaded holes of each table insert, as shown in Figure 18.

10. Insert (1) 5 x 28 roll pin into non-threaded hole of each table insert, as shown in Figure 18.

Figure 18. Set screws and roll pin installed in table insert.

IMPORTANT: Roll pins and set screws must not protrude beyond top surface of table insert or they will interfere with sanding operations.

When fully assembled, set screws and roll pin should protrude from bottom of table insert, as illustrated in Figure 19.

Figure 19. Proper table insert assembly.

Check Gearbox Oil

It is critical that you make sure there is oil in the gearbox before proceeding with the test run. Remove the spindle gearbox oil fill cap and use the dipstick to make sure the oil level is full. When full, the oil will read on the knurled portion of the dipstick.

Refer to Changing Gearbox Oil on Page 33 for more information.

NOTICE

Gearbox oil must be changed after first two hours of initial operation. This is a normal break-in procedure and will help maximize the service life of the machine. Refer to Changing Gearbox Oil on Page 33 for instructions.

Dust Collection

CAUTION DO NOT operate the Model G1071/G1071Z without an adequate dust collection system. This sander creates substantial amounts of wood dust while operating. Failure to use a dust collection system can result in short and long-term respiratory illness.

Minimum CFM at Dust Port: 400 CFM Do not confuse this CFM recommendation with the rating of the dust collector. To determine the CFM at the dust port, you must consider these variables: (1) CFM rating of the dust collector, (2) hose type and length between the dust collector and the machine, (3) number of branches or wyes, and (4) amount of other open lines throughout the system. Explaining how to calculate these variables is beyond the scope of this manual. Consult an expert or purchase a good dust collection "how-to" book.

To connect a dust collection hose:

1. Fit a 4" dust hose over dust port, as shown in Figure 20, and secure in place with a hose clamp.

Figure 20. Dust hose attached to dust port.

2. Tug hose to make sure it does not come off.

Note: A tight fit is necessary for proper performance.

Test Run

Once assembly is complete, test run the machine to ensure it is properly connected to power and safety components are functioning correctly.

If you find an unusual problem during the test run, immediately stop the machine, disconnect it from power, and fix the problem BEFORE operating the machine again. The Troubleshooting table in the SERVICE section of this manual can help.

SECTION 4: OPERATIONS

The purpose of this overview is to provide the novice machine operator with a basic understanding of how the machine is used during operation, so the machine controls/components discussed later in this manual are easier to understand.

Due to the generic nature of this overview, it is not intended to be an instructional guide. To learn more about specific operations, read this entire manual, seek additional training from experienced machine operators, and do additional research outside of this manual by reading "how-to" books, trade magazines, or websites.

()_

⚠WARNING

To reduce your risk of serious injury, read this entire manual BEFORE using machine.

⚠WARNING

To reduce risk of eye injury from flying chips or lung damage from breathing dust, always wear safety glasses and a respirator when operating this machine.

NOTICE

If you are not experienced with this type of machine, WE STRONGLY RECOMMEND that you seek additional training outside of this manual. Read books/magazines or get formal training before beginning any projects. Regardless of the content in this section, Grizzly Industrial will not be held liable for accidents caused by lack of training.

Disabling Switch (G1071)

The switch can be disabled by removing the key, as shown below. Disabling the switch in this manner can prevent unauthorized operation of the machine, which is important if it is not kept inside an access-restricted building or in a location where children may be present.

IMPORTANT: Disabling the switch only restricts its function. It is not a substitute for disconnecting machine from power when adjusting or servicing.

Figure 24. Disabling switch by removing key.

⚠WARNING

Children or untrained people can be seriously injured by this machine. This risk increases with unsupervised operation. To help prevent unsupervised operation, always disable switch before leaving machine unattended. Make sure to place key in a well-hidden or secure location!

Stock Inspection

Some workpieces are not safe to sand, or they may require further preparation before they can be safely sanded without increasing risk of injury to the operator or damaging the sanding sleeve or the sander.

Before sanding, inspect all workpieces for the following:

• Material Type: This machine is intended for sanding only natural wood fiber. This machine is NOT designed to sand glass, stone, tile, plastics, drywall, cementitious backer board, metal, etc.

Sanding metal increases fire risk. Sanding improper materials produces fine dust that poses severe respiratory risks to everyone nearby, even with a dust collector. Additionally, these materials can immediately damage the machine, sanding sleeves and spindle.

• Foreign Objects: Tramp metal, nails, staples, dirt, rocks and other foreign objects are often embedded in wood. While sanding, these objects can become dislodged and tear the sandpaper. Always visually inspect your workpiece for these items. If they can't be removed, DO NOT sand the workpiece.

• Knots: DO NOT sand stock that contains large or loose knots. Personal injury or machine damage can occur if a knot becomes dislodged during sanding.

• Wet or "Green" Stock: Sanding wood with a moisture content over 20% causes unnecessary clogging and wear on the sandpaper, increases the risk of kickback, and yields poor results.

Sanding Tips

• Replace the sanding sleeve with a higher grit to achieve a finer finish. Avoid skipping grits, as this will leave scratches in the wood.
• Extend the life of the sanding sleeve by regularly using a PRO-STIK® sanding pad (see ACCESSORIES on Page 30).
• When bevel sanding, make any necessary guide lines on the longer side of the board so they are visible during sanding.
• Keep your workpiece moving across the sanding sleeve to prevent burns, grooves or ruts in the workpiece.

Choosing Sanding Sleeves

The Model G1071/G1071Z allows you to place a different grit sanding sleeve on each spindle. The type of wood you use and your stage of finish will determine the best grit types to install.

There are many types of sanding sleeves to choose from. We recommend aluminum oxide for general workshop environments. Below is a chart that groups abrasives into different classes, and shows which grits fall into each class.

\begin{tabular}{|l|l|l|} \hline Grit & Class & Usage \ \hline 36 & Extra Coarse & Rough sawn boards, thickness sanding, and glue removal. \ \hline 60 & Coarse & Thickness sanding and glue removal. \ \hline 80–100 & Medium & Removing planer marks and initial finish sanding. \ \hline 120–180 & Fine & Finish sanding. \ \hline \end{tabular}

The general rule of thumb is to sand a workpiece with progressively higher grit numbers, with no single grit increase of more than 50. Avoid skipping grits; the larger the grit increase, the harder it will be to remove the scratches from the previous grit.

Installing/Removing Sanding Spindles

The Model G1071/G1071Z is supplied with ten rubber sanding spindles. Use the larger diameter spindles for sanding large sweeping curves and the smaller spindles for sanding more intricate curves.

When not in use, the spindles are stored on racks located on each side of the machine base, as shown in Figure 25. Each spindle is secured to the rack with a hex nut.

Figure 25. Sanding spindles.

4. Insert threaded end of spindle shaft into spindle mounting hole, then rotate clockwise and tighten by hand, as shown in Figure 27.

Figure 27. Mounting spindle.

NOTICE DO NOT tighten sanding spindle with a wrench! Sanding action will further tighten spindle. Using a wrench could make removal difficult.

Removing Sanding Spindle

1. DISCONNECT MACHINE FROM POWER!
2. Use included wrenches to hold jam nut stationary (see Figure 28) while loosening spindle retainer nut, then rotate spindle counterclockwise to remove.

Figure 28. Spindle removal (table removed for clarity).

Spindle Retainer Nut Wrench Wrench Jam Nut

Tip: If spindle has not been removed for some time and is stuck, run machine until spindle housing heats up, then retry.

Changing Sanding Sleeves

The Model G1071/G1071Z sanding sleeves are mounted over rubber drums that expand to hold the sleeve securely during operation. Over time, sleeves become worn or clogged, reducing sanding efficiency and surface quality, or you may need to change to a different grit.

Changing Sanding Sleeves on Spindles Larger Than 5/8"

1. DISCONNECT MACHINE FROM POWER!
2. Loosen hex nut located on top of spindle as shown in Figure 29. Hex nut and flange disk DO NOT need to be removed.

Figure 29. Removing sanding sleeve.

3. Remove sanding sleeve from spindle.
4. Reverse Steps 1–2 to install sanding sleeve.

Changing Sanding Sleeves on Spindles 5/8" and Smaller

1. DISCONNECT MACHINE FROM POWER!
2. Loosen set screw located in retainer nut (see Figure 30).

Figure 30. Retainer nut set screw.

3. Remove sanding sleeve from spindle.
4. Reverse Steps 1–2 to install sanding sleeve.

NOTICE

Monitor wear on sanding sleeves. Upper portion of sanding sleeve often gets very little use. If this is the case, flip sanding sleeve over and re-install. This allows maximum use of sleeve. Worn sanding sleeves will not efficiently remove material and can burn workpiece.

Installing Table Insert

The Model G1071/G1071Z is supplied with three different sized table inserts. The inserts are designed to reduce the gap between the spindle and the table opening. The hole in each insert is oblong to allow clearance when the table is tilted.

NOTICE
Always use the table insert with the smallest opening that still allows at least 1/8" clearance around the spindle.

To install table insert:

1. DISCONNECT MACHINE FROM POWER!
2. Determine appropriate insert for spindle being used.
3. Install insert over mounted spindle and into hole in table, as shown in Figure 31.

Figure 31. Installing table insert.

Note: Insert will correctly fit into table in only one position. This ensures table insert will not make contact with spindle even when table is tilted.

4. Adjust set screws shown in Figure 32 so top of insert is flush with table surface.

Figure 32. Adjusting table insert.

Sanding

Spindle sanding is typically used for inside curves and irregular shapes. The oscillating spindle moves up and down as it rotates to distribute the scratch pattern so it doesn't leave deep sanding lines, and helps to avoid workpiece burns and maximize sandpaper life.

WARNING
Keep hair, clothing, and jewelry away from moving parts at all times. Entanglement can result in death, amputation, or severe crushing injuries.

Contour Sanding

1. Ensure table is adjusted to 90° and resting on table tilt bolt, then tighten both table tilt lock levers.
2. Start dust collection system, then start sander and allow sander to reach full speed.

3. Using both hands, hold workpiece firmly on table and guide against sanding sleeve in a right-to-left direction (see Figure 33).

Figure 33. Example of contour sanding.

Bevel Sanding

The Model G1071/G1071Z features a tilting table that allows bevel sanding between 45° (front) and 20° (back), making it easier to shape edges, create angled joints, or refine complex profiles.

NOTICE Bevel sanding on a spindle sander is NOT an exact science. When table is tilted to 45°, actual angle sanded on edge of workpiece will change if workpiece is sanded at different positions around spindle.

Tip: When marking the finish line on your workpiece, always mark on outside, or longest, edge of bevel, as shown in Figure 34. This allows finish line to be viewed on top side of workpiece.

Figure 34. Bevel sanding illustration.

To bevel sand a workpiece:

1. DISCONNECT MACHINE FROM POWER!
2. Loosen both table lock levers and adjust table to desired angle, then tighten both levers to secure it (see Figure 35).

Table Tilt Lock Lever (1 of 2)

Figure 35. Location of table tilt lock lever.

3. Rotate spindle by hand to ensure it does not make contact with table insert.
4. Start dust collection system, then start sander and allow sander to reach full speed.
5. Using both hands, hold workpiece firmly on table and guide against sanding sleeve in a right-to-left direction

SECTION 6: MAINTENANCE

! WARNING Always disconnect power to the machine before performing maintenance. Failure to do this may result in serious personal injury.

Schedule

For optimum performance from this machine, this maintenance schedule must be strictly followed.

Ongoing

To minimize your risk of injury and maintain proper machine operation, shut down the machine immediately if you ever observe any of the items below, and fix the problem before continuing operations:

• Loose hardware.
• Damaged sanding sleeve.
• Worn or damaged wires.
• Any other unsafe condition.

Weekly Maintenance:

• Clean/vacuum dust buildup from beneath the table.

Every 1000 hours of use:

• Change gear oil (Page 33).

Cleaning & Protecting

Cleaning the Model G1071/G1071Z is relatively easy. Vacuum excess wood chips and sawdust, and wipe off the remaining dust with a dry cloth. If any resin has built up, use a resin dissolving cleaner to remove it.

Protect the unpainted cast iron table by wiping it clean after every use—this ensures moisture from wood dust does not remain on bare metal surfaces. Keep the table rust-free with regular applications of quality metal protectants.

Lubrication

Since all bearings are shielded and permanently lubricated, simply leave them alone until they need to be replaced. Do not lubricate them, as this will only attract dust and result in possible premature bearing failure.

DO NOT oil any exposed areas on the sander. Dust will be attracted to these areas, creating a gummy mixture that will hamper proper movement of components. Instead, lubricate exposed areas with dry, powdered graphite.

Cleaning Sanding Sleeves

As sanding sleeves are used, they will become "loaded" with saw dust. If not removed, this saw dust will harden on the abrasive surface, greatly reducing the effectiveness of the sanding sleeve. Routinely clean the sanding sleeves with a rubber gum abrasive cleaner such as the PRO-STIK® cleaner shown in Figure 42.

Figure 42. Sanding sleeve maintenance.

Always discard worn sanding sleeves. As abrasives begin to wear, grit will begin to fall off, causing deep gouges in the workpiece. Glue used to hold the grit to the paper will rub off onto the workpiece, causing burns and interfering with the final finishing.

Changing Gearbox Oil

NOTICE

Gearbox oil must be changed after first two hours of initial operation.

The spindle gearbox contains 4 quarts of 90 Wt. gear oil. Replace the gearbox oil after the first two hours of use, and then after approximately every 1000 hours of use. Remove the fill cap first (see Figure 43), then drain the gear oil from the drain plug located inside the sander base at the bottom of the gear box (see Figure 44). After oil is completely drained, install drain plug, fill with oil, then install fill cap.
