Safety Instructions for Machinery

OWNER’S MANUAL. Read and understand this

owner’s manual BEFORE using machine.

TRAINED OPERATORS ONLY. Untrained operators have a higher risk of being hurt or killed. Only allow trained/supervised people to use this machine. When machine is not being used, disconnect power, remove switch keys, or lock-out machine to prevent unauthorized use—especially around children. Make 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. nect 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.

WEARING PROPER APPAREL. Do not wear clothing, apparel 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.

NEVER STAND ON MACHINE. Serious injury may occur if machine is tipped or if the cutting tool is unintentionally contacted.

STABLE MACHINE. Unexpected movement during operation greatly increases risk of injury or loss of control. Before starting, verify machine is stable and mobile base (if used) is locked.

USE RECOMMENDED ACCESSORIES. Consult this owner’s manual or the manufacturer for recommended accessories. Using improper accessories will increase the risk of serious injury.

UNATTENDED OPERATION. To reduce the risk of accidental injury, turn machine OFF and ensure all moving parts completely stop before walking away. Never leave machine running while unattended.

MAINTAIN WITH CARE. Follow all maintenance instructions and lubrication schedules to keep machine in good working condition. A machine that is improperly maintained could malfunction, leading to serious personal injury or death.

DAMAGED PARTS. Regularly inspect machine for damaged, loose, or mis-adjusted parts—or any condition that could affect safe operation. Immediately repair/replace BEFORE operating machine. For your own safety, DO NOT operate machine with damaged parts!

MAINTAIN POWER CORDS. When disconnecting cord-connected machines from power, grab and pull the plug—NOT the cord. Pulling the cord may damage the wires inside. Do not handle cord/plug with wet hands. Avoid cord damage by keeping it away from heated surfaces, high traffic areas, harsh chemicals, and wet/damp locations.

EXPERIENCING DIFFICULTIES. If at any time you experience difficulties performing the intended operation, stop using the machine! Contact our Technical Support at (570) 546-9663.

table, getting entangled in rotating parts inside machine, or lacerated by sanding drum.

Additional Safety for Wide Belt Sanders

Serious injury or death can occur from hands getting trapped between workpiece and conveyor

Workpieces thrown by sander can strike nearby operators. Long-term respiratory damage can occur from using sander without proper use of a respirator and an adequate dust collection system. To minimize risk of getting hurt or killed, anyone operating machine MUST completely heed hazards and warnings below.

FEEDING WORKPIECE. DO NOT place fingers

under bottom of workpiece while feeding it into sander. Fingers can become pinched between workpiece and conveyor.

ENTANGLEMENT HAZARDS. DO NOT wear loose clothing, gloves, or jewelry, and tie back long hair. Never reach inside operating machine or try clearing jammed workpiece. Keep all guards in place and secure, and all doors closed.

SANDING DRUM CONTACT. Rotating sandpaper can remove a large amount of flesh in a few seconds. Keep hands away from rotating sanding drum(s) during operation. Never touch moving sandpaper on purpose.

WORKPIECE KICKBACK. A workpiece can be ejected out the front of sander at high rate of speed, and hit operator or bystanders. Never stand in-line with workpiece, never feed more than one workpiece at a time, and always adjust pressure rollers below sanding roller.

MINIMUM STOCK DIMENSION. To avoid kickback, never sand workpieces below minimum specifications listed in Data Sheet.

ADJUSTMENTS/MAINTENANCE. Make sure machine is turned OFF, disconnected from power and air, and all moving parts are completely stopped before doing adjustments or maintenance.

SANDING DUST. Sanding creates large amounts of dust and flying chips that can lead to eye injury or respiratory illness. Reduce risk of these hazards by wearing approved eye and respiratory protection when using sander.

DUST COLLECTION. Never operate without ade- quate dust collection system in place and running. Proper dust collection reduces dust in work area, which decreases risk of long-term respiratory damage, but it is not a substitute for using a respirator.

Like all machinery there is potential danger when operating this machine. Accidents are frequently caused by lack of familiarity or failure to pay attention. Use this machine with respect and caution to decrease the risk of operator injury. If normal safety precautions are overlooked or ignored, serious personal injury may occur.

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 electrican or qualified service personnel in accordance with all applicable codes and standards.

Electrocution, fire, or equipment damage may occur if machine is not correctly grounded and connected to the power

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.

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 requirements in the following section.

Figure 7. 440V transformer connections.

4. Swap out the applicable overload relay at

the locations shown in Figure 8, and set the amperage dial to values listed in Figure 8.

All wiring changes must be inspected by service personnel or a qualified electrician before the machine is connected to the power source. If, at any time during this procedure you need help, call Grizzly Tech Support at (570) 546-9663.

Note: When using a phase converter, the power from the manufactured power leg (sometimes called the wild wire) can fluctuate. Connect the manufactured power leg to the S terminal to prevent damage to the transformer. The wire from the S terminal can handle some fluctuation because it goes directly to the motor. The power going to the R and T terminals goes to the transformer and must be consistent to prevent damage.

To wire the sander to 440V:

1. DISCONNECT MACHINE FROM POWER!

2. Open the electrical box located on the back of

the machine.

3. On the transformer, remove the wire connected to the 220V terminal and connect it to the 440V terminal, as shown in Figures 7.

Clean Up

Site Considerations

Any unpainted surfaces are coated with a waxy oil to protect them from corrosion during shipment. Remove this protective coating with a solvent cleaner or citrus-based degreaser such as Grizzly’s G7895 Degreaser. To clean thoroughly, some parts may need to be removed. For opti-

mum performance from your machine, make sure you clean all moving parts or sliding contact surfaces that are coated. Avoid chlo-

rine-based solvents as they may damage painted surfaces should they come in contact.

Gasoline and petroleum products have low flash points and could explode if used to clean machinery. DO NOT use gasoline or petroleum products to clean the machinery.

Floor Load

Refer to the Machine Data Sheet for the weight and footprint specifications of your machine. Some shop floors may require additional reinforcement to support both the machine and operator.

Working Clearance

Working clearances can be thought of as the distances between machines and obstacles that allow safe operation of every machine without limitation. Refer to the Machine Data Sheet for dimensions of your machine. Consider existing and anticipated machine needs, size of material to be processed through each machine, and space for auxiliary stands and/or work tables. Also, consider the relative position of each machine to one another for efficient material handling. Be sure to allow yourself sufficient room to safely run your machines in any foreseeable operation and keep dust collection hoses off the floor and out of the way.

Lack of ventilation while using solvents could cause serious personal health risks, fire, or environmental hazards. Always work in a well ventilated area to prevent the accumulation of dangerous fumes. Supply the work area with a constant source of fresh air.

Lighting

Lighting should be bright enough to eliminate shadows and prevent eye strain. Electrical circuits should be dedicated or large enough to handle combined motor amp loads. Be sure to observe local electrical codes for proper installation of new lighting or circuits.

Unsupervised children and visitors entering a shop could suffer serious personal injury. Ensure child and visitor safety by keeping all entrances to the shop locked at all times. DO NOT allow unsupervised children or visitors in the shop at any time.

Dust Collection

An efficient and clean dust collection system is essential to the proper function of the sander. Ensuring a healthy work environment is also dependent upon cleaning and maintaining your dust collection system. For the H2933/H2934/ G0447 we recommend a minium of: 2400 CFM, and for the G0581: 4000 CFM is recommended.

To hook up a dust collection system:

1. Install the dust ports (Figure 12) to the

mounting locations on the top of the sanding unit with the supplied M6-1 x 10 Phillips head screws.

Air Inlet

Figure 10. Air inlet located on regulator.

2. Make sure the red handle on the regulator

is in the open position (parallel with the air inlet).

Lift the regulator knob (Figures 10 and 11)

and turn it until the air pressure gauge reads 75 PSI. Note: Turn the knob clockwise to

increase the air pressure and counterclockwise to lower the air pressure.

Push the regulator knob down until it snaps.

H2933/H2934/G0447/G0581 Wide Belt Sander -19-

Pressure Rollers

The pressure rollers have been set at the factory, but for safety, you should verify that they are set below the level of the sanding roller.

It is absolutely essential to keep the pressure rollers set below the level of the sanding roller. If the pressure rollers are even, or higher than the sanding roller, the wood WILL be propelled from the sander at a high rate of speed. This situation could cause serious kick-back injury.

To check the pressure roller height:

1. DISCONNECT THE SANDER FROM THE

POWER SOURCE!

2. Place a piece of scrap wood of uniform thickness across the table so it spans both the front and the rear pressure rollers at the same time.

Start Up

Serious personal injury could result if the machine is connected to the power source during assembly or adjustment. Wait until the machine is turned off, unplugged, and all working parts have come to a complete stop before you attempt to assemble or adjust the machine!

Loose hair and clothing could get caught in machinery causing serious personal injury. Keep loose clothing rolled up and long hair tied up and away from machinery.

3. With the air pressure connected and the

sanding belt installed and tensioned, manually raise the table and verify that the board touches both pressure rollers before it touches the sanding belt.

Note: If the board does not touch both pres-

SECTION 4: OPERATIONS

Choosing SandpaperOperation Safety

Your safety is important! Please follow the warnings below during this entire section:

To avoid serious personal injury, read and become familiar with the entire instruction manual before using this wide belt sander.

Damage to your eyes, lungs, and ears could result from failure to wear safety glasses, a dust mask, and hearing protection while sanding with this machine.

The grit you choose will depend on the type of work, the species of wood and the stage of finishing. Below is a chart that groups abrasives into different categories and shows which grits fall into each-one. We recommend using aluminum oxide sanding belts for the best results.

Grit Type

80-100

120-150

The general rule of thumb is to sand a workpiece with progressively higher grit numbers, with no one grit increase of more than 50; however, the type of wood and desired finish will determine the best grit to use.

Coarse

Medium

Fine

Loose hair and clothing could get caught in machinery and cause serious personal injury. Keep loose clothing rolled up and long hair tied up and away from machinery.

Table Movement

Adjusting Feed Rate

Table height can be adjusted manually or with the digital key pad and motor (see Figure 15).

Manual Table Movement: Turn the handwheel located under the front of the infeed table for manual table positioning.

Motorized Table Movement: Press the TABLE UP or TABLE DOWN key once for motorized table positioning in 0.005" (0.1mm) increments.

Numerical Key Pad: Enters the position of

sanding depth.

Metric or Standard Key: Press and hold the

SET button for 3 seconds to calibrate display at the current board thickness; or press and hold key for 10 seconds to toggle the display between metric and standard measurement.

Table Start Key: Moves table to a preset sand-

ing depth.

Table Stop Key: Stops table movement imme-

diately.

The dial attached to the side of the feed belt gear box (Figure 16) adjusts the feed rate of the sander.

Note: Never adjust the feed rate dial unless the conveyor belt is running, otherwise you can damage the control.

Changing Feed Rate: Turn the dial clockwise to

decrease the feed rate and counterclockwise to increase it.

Determining Ideal Feed Rates: Softwoods

typically require a faster feed rate than hardwoods; however, there is no definitive rule to follow when determining the best feed rate. As a general rule, always start with the slowest feed rate and work your way up. We always recommend testing the feed rate using scrap wood similar to your workpiece. Be sure to monitor the amperage meter when adjusting the feed rate. Decrease the feed rate if the load begins to slow the motor RPM.

Amp Draw Meter

The amperage draw meter (Figure 17) is located above the control panel. Use the meter to monitor the amperage draw on the machine while per-

forming sanding operations.

As a general rule, always start with a small load and work your way up. DO NOT work your machine to its maximum load, where you can hear the motor lose RPM; instead, make multiple passes or install a coarser grit paper.

Amp load will be directly affected by many factors such as feed rate, depth of cut, wood type, sandpaper grit, and workpiece width. If the amp load is in the red load range, the machine is overloaded and motor damage will occur. Keep the amp load in the green range during operation.

Figure 17. Typical amp draw meter

and load chart.

NOTICE

DO NOT VOID WARRANTY! Keep the amp draw within the GREEN load range shown on the AMP LOAD CHART. If you operate the sander in the RED load range, capacitor or motor failure will occur and will not be covered under warranty.

-24- H2933/H2934/G0447/G0581 Wide Belt Sander

Sanding Workpiece

Platen Adjustment

Typically, no more than 0.5mm (approx. 1⁄64") of material is removed during each pass. Attempts to remove too much material can cause jamming, wood burning, rapid paper wear or tearing, poor finish, short motor life, and belt slippage.

The following is the correct sanding operating procedure:

1. Put on safety glasses, a dust mask, and hearing your protection!

2. Turn ON the dust collector.

3. On the initial pass, set the table to approxi-

mately 0.25" greater than the thickness of the workpiece.

Note: This initial pass setting reduces the

chance of overloading the sander on unde-

tected high points on the workpiece.

4. Continue to raise the table 0.0625" between each successive pass until the sander begins to sand the workpiece.

NOTICE

It may be necessary to send wide stock through the sander two or three times between table height adjustments. This reduces the likelihood of burning the wood if there is a high spot.

Your sander is equipped with an adjustable felt platen and graphite slip for those extra sensitive sanding operations. The platen position allows

for 3 basic types of sanding. These different positions can be adjusted by rotating the height lever shown in Figure 18.

Scale and

Pointer

Height

Lever

Lock

Lever

Figure 18. Platen height controls.

The three basic platen positions:

Platen Up: The platen is raised above the level

of the sanding rollers. This position allows the front roller to remove large amounts of material quickly, but leaves a rough finish. The best belt grit for this position is #100 or coarser.

Platen Even: The platen is set even with the sanding rollers. The rollers work together with the platen to produce intermediate/final finishing. The best belt grit for this position is #100-#180.

Platen Down: The platen is lowered below the sanding rollers. The majority of the work is accomplished by the platen pressure on the workpiece. The result is a smooth, flat finish. The best belt grit for this position is #180 or finer. Avoid lowering the platen more than 0.2 mm below the sanding belt rollers, or you will prematurely wear the platen.

Note: The platen scale is broken down in millimeter increments.

SECTION 6: MAINTENANCE

General

Your safety is important! Please follow the warnings below during this entire section:

Disconnect power to the machine when performing maintenance, assembly or adjustments. Failure to do this may result in serious personal injury.

Loose hair and clothing could get caught in machinery and cause serious personal injury. Keep loose clothing and long hair away from moving machinery.

Schedule

Weekly

Grease the grease fittings located on the feed belt roller axles and the sanding belt roller axles. They are identified with yellow labels.

Monthly

Apply a generous amount of grease to the table elevation screws. Be sure to recover the adjustment screws with the dust covers when finished.

Remove the lower side panel to access the table lifting mechanism. Apply grease to the chain and gears associated with the table lifting mechanism. Be careful to not get grease on the V-belts. This could cause them to slip off of the pulleys.

After the First 100 Hours

The oil inside the conveyor gear reducer should be replaced after the first 100 working hours of operation. We recommend 90 Wt. gear oil.

Every 2500 Hours

After the first conveyor gear reducer oil change, replace the oil after every 2500 working hours of operation. We recommend 90 Wt. gear oil.

The following items should be checked each time the sander is used:

• Loose mounting bolts.

• Damaged sanding belt.

• Worn or damaged wires.

• Water collection cups filled with water.

• Dust trap.

• Safety features.

• Any other condition that could hamper the

safe operation of this machine.

H2933/H2934/G0447/G0581 Wide Belt Sander -27-

Sanding Belts

You can greatly increase the lifespan of your sanding belts if you clean them often. As mentioned on Page 26, cleaning pads are the fastest way to remove saw dust build-up.

Air System

The air system is durable and reliable; however, components do wear with age. If you suspect that an item in your air system may be having problems, see the Air System Diagram on Page 39.

• Adjust regulator to 75 PSI.

• Carefully inspect all air lines for cracks, tears

or hardening. Replace faulty hoses.

• Check the air connections for leaks. A small

amount of soapy water in a questionable area will bubble if there is a leak.

Dust and Water

Traps

There are three traps on this wide belt sander. One water trap is attached to the bottom of the air regulator, and two dust traps are attached on the air diaphragm assemblies. Cleaning is easy, with the system under air pressure, you can push the lower drain valve and empty regulator water trap (Figure 21). Replace the internal white moisture filters yearly. To empty the dust trap bowls, relieve the air pressure and then unscrew and empty the bowls (Figure 22). DO NOT allow the water trap and dust bowls to become full.

• Make sure lines are not clogged. Remove

a questionable line and blow through it as a test.

If a component in the air system is malfunctioning, bleed all air from the system, and fix the problem before you resume sanding.

SECTION 7: SERVICE

Table Calibration

—If it does, the sander is properly calibrated

and accurate to the nearest 0.005".

— If it does not, you must recalibrate the digital

thickness scale.

NOTICE

The digital thickness gauge has been calibrated at the factory and should require no further adjustment. However, we recommend verifying its accuracy.

Use the first board fed through the sander to test the accuracy of the digital thickness gauge.

To calibrate the digital thickness scale:

1. Using a properly set-up planer, plane a board

to uniform thickness.

2. Lower the sander table far enough to place the planed board under the sander roller.

3. Manually raise the table until the board just touches the sanding roller.

4. Remove the board without changing the table height. This ensures the table will be properly adjusted for the first sanding pass.

5. Run the board through the sander several times at the initial height setting. Manually raise the table 0.020" and pass the board through the sander several more times. Monitor the amperage meter and the resulting load on the sander.

To recalibrate the digital thickness scale:

1. Without moving the table height, enter the

numerical measurement of the average thickness of the sanded wood into the digital key pad on the control panel.

Note: The average thickness of the sanded

wood should now be flashing on the digital read-out.

2. Press and hold the key until the display stops flashing. The sander is now correctly calibrated.

Platen Service

To replace the platen felt and graphite pad:

1. DISCONNECT THE SANDER FROM THE

POWER SOURCE!

2. Open the left access door, and use the platen tool, as shown in Figure 23, to remove the platen.

3. Replace platen felt pad and graphite pad.

4. Reinsert the platen until it stops.

6. Measure the thickness at various points

around the board using a precise micrometer or set of calipers. Continue sanding the board at that height until the average thickness measurement is within

Note: These final passes should be done

without adjusting the table height. This ensures the most consistent average thickness.

Eventually the brake pads will wear out. Checking and replacing these is a simple project that can be done in the shop, with the exception of having the rotor resurfaced on a lathe.

To check the brake pads:

1. Disconnect the sander from the power source and remove air pressure completely!

2. Remove the four screws that secure the

access panel on the right-hand side of the machine.

3. The brake caliper is located underneath the rotor in Figure 24, which is attached to the motor arbor.

To replace the brake pads:

1. Disconnect the sander from the power

source and remove air pressure completely!

2. Remove the nuts from the two mounting

bolts and the two snap rings on the mounting pins behind the bracket.

3. Pull the mounting pins out of the caliper bracket and remove the air line from the caliper. The caliper should now be able to be removed.

4. Disassemble the brake caliper and remove the cap screws securing the brake pads.

5. Remove the brake rotor and have it professionally resurfaced at an automotive machine shop if it has gouges in it. If visible cracks are present in the brake rotor, replace it with a new one. Remove oil and dirt from the rotor with automotive brake cleaner. Once clean, only handle the rotor with a dry rag and install exactly the reverse of removal.

6. Install new brake pads, mount the caliper and reconnect the air line.

Oscillation Timing

NOTICE

The oscillation adjustments have been performed at the factory and should require no further attention. However, we recommend verifying the settings.

When the oscillation is correctly adjusted, the sanding belt oscillates to the left and to the right at the same speed. If the sanding belt makes contact with a limit switch, as shown in Figure 25, the emergency braking system will activate and stop the sander immediately.

Limit

Switches

3. An adequate stream of air through the air fork gap (Figure 26) is essential for proper oscillation. If the jet of air is weak through the gap, the belt will track away from the controller and into the limit switch on the opposite end of the roller. The pivot action of the upper roller, and the resulting oscillation of the belt, are dependent upon adequate airflow through the air fork gap.

(Top View)

Figure 25. Improper oscillation.

To check the sanding belt oscillation:

1. Be sure the sanding belt is properly installed

and the belt tension knob and air supply are ON.

2. Turn ON the sanding belt.

—If the belt oscillates without contacting the

limit switches, but the oscillation time to the left and right are NOT equal, proceed to Step

5, on Page 33.

Figure 26. Oscillation components.

To set the correct amount of airflow through

the air fork gap:

1. Remove the sanding belt and turn the belt

tension knob to the tensioned position.

2. Loosen the lock nut on the airflow adjustment knob (Figure 27).

3. Turn the airflow adjustment knob (Figure 27) clockwise until the airflow is completely OFF. The upper roller should pivot to the right.

4. Slowly turn the airflow adjustment knob counterclockwise, and continue turning up the air pressure until the roller pivots to the left.

H2933/H2934/G0447/G0581 Wide Belt Sander -31-

5. Tighten the lock nut (Figure 27) to secure the airflow adjustment knob.

6. Restrict the airflow across the air fork gap with a scrap piece of wood. You should notice the roller pivot to the right. When the stick is removed, the roller should pivot back to the left.

7. Test the oscillation by running the sander. Make note of the time it takes for the belt to oscillate from left-to-right and from right-to-

left.

When correctly timed, the oscillation should

take a similar amount of time to oscillate.

—If the oscillation time to the right is 2 sec-

onds, but the oscillation time to the left is longer, loosen the oscillation adjustment knob (Figure 28) and move it to the left until proper tracking is achieved. Tighten down the oscillation adjustment knob when satisfied.

Figure 28. Oscillation adjustment knobs.

—If the oscillation time to the left is 2 seconds,

but the oscillation time to the right is longer, loosen the oscillation adjustment knob and move it to the right until proper tracking is achieved. Tighten the oscillation adjustment knob when satisfied.

8. Continue to the next page to adjust the oscillation speed.

Oscillation Speed Table Parallelism

The oscillation speed of the sanding belt is adjustable. Different oscillating speeds yield different sanding results. We recommend trying various speeds on a scrap piece of wood similar to the final workpiece.

To adjust the oscillation speed:

The table has been adjusted at the factory and should require no further attention. However, we recommend verifying that it is parallel with the sanding roller.

NOTICE

1. Loosen the lock nut on the speed control adjustment knob (Figure 29).

Lock Nut

Figure 29. Speed control adjustment knob.

2. Turn the knob clockwise to decrease the

oscillation speed and counterclockwise to increase it.

3. Tighten the lock nut loosened in Step 1 to secure the knob.

The corners of the table can be independently adjusted up or down. By disconnecting the chain and turning the pertinent table elevation screw sprocket, (Figure 30) table parallelism can be achieved.

Adjusting the table parallelism can be a very tedious task that takes a great amount of patience. DO NOT adjust the table unless you are having trouble sanding your workpiece to a uniform thickness.

If a table adjustment is needed, take precise notes on the positioning of the table elevation screws. This will allow the original setting to be re-established.

Elevation Screw

Sprockets

H2933/H2934/G0447/G0581 Wide Belt Sander -33-

To adjust the table parallelism:

1. Pass a 37" wide board through the sander

until the entire surface of the board is making contact with the sanding belt.

Pressure Rollers

To adjust the pressure rollers:

2. Measure the thickness of the board at vari-

ous points around the edge.

3. If there is a variation of thickness, the table can be adjusted accordingly.

4. DISCONNECT THE SANDER FROM THE POWER SOURCE!

—For minor adjustment, loosen the table

mounting bolts shown in Figure 31 and rotate

the elevation screw flange.

—For major adjustment, mark the chain loca-

tion on all sprockets, remove the chain from the sprocket to be adjusted, and turn the sprocket counterclockwise to raise the table. One quarter of a turn raises or lowers an elevation screw approximately 0.020"

2. Plane a 6' long 2x4 to a uniform thickness and cut it in half. Place one board along the length of the feed belt on the right-hand side and place the other board on the left-hand side.

3. With the sanding belt tensioned (Figure 32),

move the sanding rollers by hand and manu-

ally raise the table until you hear the sandpaper just contact the surface of the wood. DO NOT continue to raise the table beyond that point.
