SECTION 3: CIRCUIT REQUIREMENTS

220V Single-Phase

The Model G9983 features a 5 HP, 220V singlephase motor. This motor will safely draw about 30 amps under load. The Model G9983 also features a 1 ⁄

4

HP feed motor that draws approximately 1.8

amps under load. Total amperage draw for this machine is approximately 32 amps under load.

Use a 35 amp circuit breaker for the Model

G9983. Make sure the wiring in your circuit is rated to handle the amperage draw from your machine. If frequent circuit failure occurs when using the sander, contact our Service

Department. The sander must be connected to its own dedicated circuit and should not share a circuit with any other machine. A standard 2-pole breaker is necessary for use with the sander.

We recommend using a NEMA-style 6-50 plug and outlet (similar to the one shown in Figure 1 ) for the Model G9983. You may also “hard-wire” the sander directly to your panel, provided you place a disconnect near the machine. Check the electrical codes in your area for specifics on wiring requirements.

Figure 1. Plug configuration for 220V, singlephase 6-50 plug and outlet.

-6G9983 15" Open-End Wide-Belt Sander

Grounding Extension Cords

We do not recommend the use of extension cords on 220V equipment. It is much better to arrange the placement of your equipment and the installed wiring to eliminate the need for extension cords.

This equipment must be grounded. Verify that any existing electrical outlet and circuit you intend to plug into is actually grounded. Under no circumstances should the grounding pin from any three-pronged plug be removed. Serious injury may occur.

In the event of an electrical short, grounding reduces the risk of electric shock by providing a path of least resistance to disperse electric current. This tool is equipped with an electric cord that has an equipment-grounding conductor which must be properly connected to a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.

Improper connections of the electrical-grounding conductor can result in the risk of electric shock.

The conductor with green or green and yellow striped insulation is the electrical-grounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment grounding conductor to a live terminal.

Wiring

The Model G9983 comes prewired for 220 volt operation. Wiring diagrams are provided at the back of this manual should it be necessary to repair or revise the wiring. Always consult a qualified electrician when doing any electrical work on this equipment.

We have covered some basic electrical requirements for the safe operation of your

Sander. These requirements are not necessarily comprehensive. You must be sure that your particular electrical configuration complies with local and state codes.

Ensure compliance by checking with your local municipality or a licensed electrician.

Clean Up

The 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 optimum performance from your machine, make sure you clean all moving parts or sliding contact surfaces that are coated.

Avoid chlorine-based solvents as they may damage painted surfaces should they come in contact. Always follow the manufacturer’s instructions when using any type of cleaning product.

Do not use gasoline or other petroleum-based solvents to clean with.

They have low flash points which make them extremely flammable. A risk of explosion and burning exists if these p r o d u c t s a r e u s e d .

Do not smoke while using solvents. A risk of explosion or fire exists and may result in serious personal injury.

Site Considerations

FLOOR LOAD

Your new wide-belt sander represents a large weight load in a moderate sized footprint. Most shop floors will be adequate for the weight of the wide-belt sander; however, some floors may require additional support. Contact an architect or structural engineer if you have any question about the ability of your floor to handle the weight.

WORKING CLEARANCES

Working clearances can be thought of as the distances between machines and obstacles that allow safe operation of every machine without limitation. 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.

LIGHTING AND OUTLETS

Lighting should be bright enough to eliminate shadow and prevent eye strain. Electrical circuits should be dedicated or large enough to handle combined motor amp loads. Outlets should be located near each machine so power or extension cords are not obstructing high-traffic areas.

Be sure to observe local electrical codes for proper installation of new lighting, outlets or circuits.

Many of the solvents commonly used to clean machinery can be toxic when inhaled or ingested. Always work in wellventilated areas far from potential ignition sources when dealing with solvents. Use care when disposing of waste rags and towels to be sure they do not create fire or environmental hazards.

Make your shop “child safe.” Ensure that your workplace is inaccessible to children by closing and locking all entrances when you are away. Never allow visitors in your shop when assembling, adjusting or operating equipment.

-12G9983 15" Open-End Wide-Belt Sander

Beginning Assembly

Most of your new wide-belt sander has been assembled at the factory, but some setup is required after delivery. We have organized the setup process into steps. Please make sure the sander is placed in its final position in your shop and follow along in the order presented in this section.

Handwheel Handle

To install the handwheel handle:

1.

Thread the handle into the handwheel as shown in Figure 7 .

2.

After handle is completely threaded down, tighten the jamnut so the handle will not come loose. Make sure to leave the plastic sleeve loose enough to rotate when you crank the handwheel.

Keep loose clothing out of the way of machinery and keep hair pulled back.

Disconnect power to the machine when performing any setup or assembly. Failure to do this may result in serious personal injury.

Wear safety glasses during the entire setup process. Failure to comply may result in serious personal injury.

Some metal parts may have sharp edges on them after they are formed. Please examine the edges of all metal parts before handling them. Failure to do so could result in injury.

Figure 7.

Install handle onto handwheel.

NOTICE

The waxy grease must be completely cleaned from the table column for smooth table height adjustments.

G9983 15" Open-End Wide-Belt Sander -13-

Platen

The housing for the platen can be accessed by opening the door on the left-hand side of the machine.

A graphite sheet is mounted on the platen. Before installing, make sure that the graphite sheet is mounted on the left-hand side of the platen, as it will be inserted. Figure 8 shows the platen being installed correctly.

The direction of the graphite sheet is important because it must wrap around the platen in the same direction as the sanding belt rotates. If not, the sanding belt will unwrap the graphite sheet, exposing the sanding belt to the metal body of the platen. Note: the graphite sheet on the platen is considered a “consumable” item, similar to the sanding belts, and normal wear and tear from machine operation is not covered under warranty. For additional information on the platen, turn to

page 33.

To insert the platen:

1.

Line up the platen dovetail with the housing so it is positioned as described above.

2.

Slide the platen into the housing as far as it can go.

The platen must now be set even with the sanding rollers.

To set the platen even with the belt rollers:

1.

Lower the conveyor table as far as it will go.

2.

Open the access door on the left-hand side and locate the platen adjustment knob shown in Figure 9 .

Figure 9.

Use this knob to raise/lower the platen.

3.

Place a straightedge across both lower belt rollers and rotate the adjustment knob until the platen barely touches the straightedge.

The platen should now be set even with the belt rollers.

Graphite Sheet

Figure 8.

Install the platen with the graphite sheet on the left-hand side.

-14G9983 15" Open-End Wide-Belt Sander

Air Hose

The air hose connection is located at the regulator on the front of the machine.

To connect the air hose:

1.

Fit the hose over the regulator nozzle.

2.

Secure the hose with a hose clamp as shown in Figure 10 and turn on your air compressor.

3.

Regulate the air pressure to 75 PSI.

This is the normal operating pressure for the

Model G9983.

Sanding Belt

The Model G9983 is designed for 16" x 48" sanding belts.

To install a sanding belt:

1.

Open the left-hand side door for access.

2.

Make sure the greasy protective coating has been cleaned from the metal belt roller before installing sanding belt.

Fit the sanding belt completely over the three sanding rollers as shown in Figure 11 . The belt will move counter-clockwise during rotation—make sure that the arrows on the inside of the belt point in the direction of rotation.

Figure 10.

Secure air hose with a hose clamp.

NOTICE

DO NOT exceed 75 lb. of air pressure.

Damage to the machine components may result.

NOTICE

The main shut off valve should remain closed until air pressure is needed. This will reduce wear and tear on the air system components.

Sanding Belt Tension

The sanding belt tension is controlled by a switch located inside the upper portion of the machine

(see Figure 12 ). To locate it, open the access door on the left-hand side of the sander.

Figure 12.

This is the belt tension switch.

To Tighten Belt Tension:

Flip the switch up. The vertical cylinder will automatically tighten the top roller to the correct tension.

To Loosen Belt Tension:

Flip the switch down. The vertical cylinder will automatically loosen the belt tension for belt removal.

NOTICE

The belt tension switch is part of the air control system. This means the machine must have air pressure for the switch to work correctly.

NOTICE

Always tighten belt before starting sander!

Pressure Rollers

Always 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 personal injury.

The pressure rollers have been set at the factory, but for increased personal safety, you should verify that they are below the sanding belt.

To check the feed pressure:

1.

Disconnect the sander from the power source!

2.

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

3.

Make sure the platen is even with the sanding belt rollers.

4.

With the air pressure connected, the sanding belt installed, and the belt tension switch ON , slowly raise the conveyor and verify that the board touches both pressure rollers before it touches the sanding belt.

If the board does not touch both pressure rollers before it touches the sanding belt, then the pressure rollers must be adjusted before operation. See Section 8:

Service Adjustments for step-by-step instructions on how to do this.

Dust Collection

DO NOT operate the Model G9983 without an adequate dust collection system. This machine creates substantial amounts of wood dust while in operation. Failure to use a dust collection system may result in short and long-term respiratory illness.

The dust collection port is located on top of the sander and measures 5" in diameter. It will be necessary to attach a 5" dust collection pipe over this port before operation. If you have rigid ducts in your dust collection system, we recommend that you connect the ducts to your sander with flexible hose. The flex-hose easily attaches with a

5" hose clamp and it absorbs any movement that may occur during operation. Please refer to the

Grizzly catalog for current price and ordering information.

Your dust collector must be able to move 800-

1200 CFM at the Wide-belt Sander.

If you have a remotely located dust collector, or if you are operating more than one machine at a time, ensure that your dust collector has the capacity and power to meet this requirement. A fine layer of dust may be present on your stock as it comes out of the sander. This is normal.

Test Run

Once the assembly is complete and the adjustments are done to your satisfaction, you are ready to test run the sander.

Before you test run your machine:

1.

Read back through Section 1: Safety

Instructions , Section 4: Assembly , and the previous instructions in this section to make sure that all precautions have been taken for safe operation.

2.

Make sure the machine is connected to an air compressor and the pressure gauge on the sander reads 75 PSI.

3.

Make sure that any tools or foreign objects have been removed from the machine.

4.

Last but not least, make sure the wiring is correct. Did you follow the instructions from

Section 2: Circuit Requirements ? If you are not confident with the wiring, go back and double check that all precautions have been taken to ensure safety to the operator and the circuit. When you are confident, connect the machine to the power source. The power indication light on the control panel should light up.

Always wear a dust mask in addition to using a dust collector. Dust masks filter out the smaller particles of dust that dust collectors cannot trap.

DO NOT attempt to investigate or adjust any features of the machine while it is running.

Wait until the machine is turned off, unplugged and all working parts have come to a rest before you do anything! Failure to do so could result in severe personal injury.

To test run the sander:

1.

Turn on the power supply at the main panel.

G9983 15" Open-End Wide-Belt Sander -17-

Long term exposure to this machine during operation may cause hearing loss. Wear approved hearing protection to minimize this risk!

2.

Start both the sanding belt and the feed belt, making sure your finger is poised over the

STOP button, just in case there is a problem.

The wide-belt sander should run smoothly, with little or no vibration or abnormal rubbing noises. It is normal, however, for the air operated tracking to make a rhythmic back and forth noise.

Strange or unnatural noises should be investigated and corrected before operating the machine further. To avoid injury or damage to the machine, DO NOT attempt to make adjustments to the machine without turning it off and unplugging it from its power source.

If noises occur that cannot be found by visual inspection, feel free to contact our Service

Department for help.

SECTION 6: OPERATIONS

Before Starting

Keep loose clothing out of the way of machinery and keep hair pulled back during operations.

Before beginning any work with your machine, make sure you have read through this entire manual. Your safety while running this machine absolutely depends on your familiarity and compliance with the information in this manual.

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

Choosing Sandpaper

Wear safety glasses during the entire operation process. Failure to comply may result in serious personal injury.

Always wear a dust mask in addition to using a dust collector. Dust masks filter out the smaller particles of dust that dust collectors cannot trap.

NOTICE

The following section was designed to give instructions on the basic operations of this wide-belt sander. However, it is in no way comprehensive of every wide-belt sander application. WE STRONGLY RECOMMEND that you read books, trade magazines, or get formal training to maximize the potential of your wide-belt sander.

The Model G9983 takes 16"W x 48"L sanding belts.

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 classes and shows which grits fall into each class. We recommend using aluminum oxide for best results.

Grit

60

80-100

120-150

Type

Coarse

Medium

Fine

The general rule of thumb is to sand a workpiece with progressively higher grit numbers, with no one grit increase of more than 50.

Ultimately, the type of wood you use and your stage of finish will determine the best grit types to install on your sander.

5.

Replace the motor cover and secure it with the cap screw.

-20G9983 15" Open-End Wide-Belt Sander

Load Meter

The load meter shown in Figure 16 displays the current amperage draw of the sanding belt motor.

The needle rises when you increase the load on the sanding belts and decreases when you decrease the load. Use this meter to avoid overloading your machine with too heavy of a cut.

NEVER exceed 30 amps—this is the maximum that your machine can safely handle!

Since various types of stock will react differently to various loads, use trial-and-error to determine the best settings for your applications. As a general rule, always start with a small load and work your way up. DO NOT push your machine to its maximum load; instead, use multiple passes or install a coarser grit paper.

Figure 16.

This is the load meter.

Long term exposure to this machine while operating may cause hearing loss. Wear approved hearing protection to minimize this risk!

Operation

Under most sanding conditions, a normal cut is no more than .5mm (approx. 1 ⁄

64

"). This depth can be achieved by 1 ⁄

8 th turn of the conveyor height handle. Attempts to remove too much can cause jamming, wood burning, rapid paper wear or tearing, poor finish and belt slippage. For each pass, turn the stock 180° to ensure an even cut.

Make sure any stock that you run through the sander is clean and free of any defects or foreign materials that might damage the sanding or conveyor belt.

NOTICE

We strongly recommend sending wide stock through the sander two or three times after the correct height has been established. This is an important step to prevent burning your wood or ruining sandpaper.

The following is the correct start-up and operating procedure:

1.

Start the dust collector.

2. Make the thickness adjustment by placing the workpiece on the conveyor table and turn ing the conveyor handle until the workpiece can be sanded and fed through smoothly.

Turning the handle clockwise will raise the conveyor table. Turning the conveyor handle counter-clockwise will lower the conveyor table.

3.

Remove the workpiece from the conveyor belt.

4. Start the sander and feed your stock.

Retrieve by standing at the side—not at the outfeed end.

G9983 15" Open-End Wide-Belt Sander -21-

Platen Depth

The platen position allows for 3 types of operation. These different positions can be adjusted by rotating the knob shown in Figure 17 . Notice that the knob has a scale on it. By keeping track of how many revolutions you have rotated the knob, you can determine how far you have moved the platen.

Cleaning Pads

Cleaning Pads (one is shown in Figure 18 ) are the perfect way to enhance your wide-belt sanding operations. Simply set the conveyor table to height and feed the pad through to “unload” a used sanding belt. This cleaning will greatly increase the lifespan of your sanding belts. Since each pad can be used dozens of times, you will actually save money in the long run. Check with the current Grizzly catalog for more details.

Figure 17.

The scale on this knob tells you how far you have moved the platen.

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 .2MM below the sanding belt rollers—this is the equivalent to

1 full turn of the knob.

SECTION 7: MAINTENANCE

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

General

Make a habit of inspecting your Model G9983 each time you use it. Failure to routinely inspect your wide-belt sander for damage and wear could result in unsatisfactory work results, premature component or machinery failure, or operator injury. We recommend you create a checklist for routine inspection and maintenance. Check for the following conditions and repair or replace when necessary.

• Loose mounting bolts.

• Worn or damaged sanding belt.

• Worn or damaged cords, plugs or switch.

• Damaged V-belt.

• Any other condition that could hamper the safe operation of this machine.

Cleaning Sanding Belts

You can greatly increase the lifespan of your sanding belts if you clean them often. As mentioned on page 22 , cleaning pads are the best way to do this.

Whenever sanding belts decrease in performance because of heavy loading, feed the cleaning pad through the sander. Repeat this process until the sanding belts are clean again—this will ensure optimum performance.

Emptying Filters

There are two filters on the Model G9983. The first filter is located under the main regulator that houses the pressure gauge. The second filter, shown in Figure 19 , is located near the oscillation controls. Since the eye fork configuration is prone to collecting sawdust, check and empty this filter often.

Lubrication

Roller bearing blocks must be lubricated every 20 hours of operation with high-quality, lithium based grease via grease fittings on top of each block.

Other moving parts, such as chains, should be lubricated periodically with a light machine oil. Do not use too much lubrication because excess can attract dirt and sawdust and will clog the chain mechanism.

SECTION 8: SERVICE ADJUSTMENTS

Keep loose clothing out of the way of machinery and keep hair pulled back.

Oscillation Timing

The first step in adjusting the oscillation is timing the side to side movement the belt makes when oscillating. The belt should take the same amount of time to travel to one side as it did the other.

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

Keep your hands clear of the sanding belt when making the adjustments in this step.

The sandpaper is designed to remove a lot of material quickly whether it is wood or skin!

Wear safety glasses during the entire assembly process. Failure to comply may result in serious personal injury.

To time the oscillation movement:

1.

Open both access doors to the upper part of the machine so you can view the belt movement. The sanding belt should also be on the rollers and tightened. Turn the sanding belt

ON .

2.

Count the amount of time it takes the belt to move from one side to the other. If the oscillation balance is correct, the belt will move from one side to the other in even intervals.

If the balance is not correct, the belt may move to one side very quickly, then very slowly to the other.

3.

If the belt immediately moves too far and shuts off the machine, then loosen the oscillation timing control knob shown in Figure 20 and move it toward the front or rear of the machine to rotate the eccentric.

4.

Loosen the belt tension, rebalance the sanding belt and retighten the belt tension.

Repeat steps 2 and 3 .

G9983 15" Open-End Wide-Belt Sander -25-

Oscillation Speed

Use the valve shown in Figure 21 to control the speed of the sanding belt oscillation. Make sure the oscillation is balanced before adjusting the speed.

Figure 20.

This is the oscillation timing control knob.

5.

When you get the belt to oscillate without stopping, experiment with the timing knob to see the effect its movement has on the belt oscillation.

6.

Position the timing knob so the belt moves from one side to the other, back and forth, in even intervals.

7.

Lock the knob in place by turning it clockwise.

Figure 21.

Use the knob on this valve to control oscillation speed.

Long term exposure to this machine during operation may cause hearing loss. Wear approved hearing protection to minimize this risk!

Keep loose clothing out of the way of moving machinery and keep long hair pulled back.

To increase the oscillation speed , open the valve (turn the knob counter-clockwise). For normal operation, adjust the oscillation speed so each direction of belt movement takes approximately 2 seconds. When the speed is correct, tighten the jamnut so the knob will not move.

To decrease the oscillation speed , close the valve (turn the knob clockwise). When the speed is correct, tighten the jamnut.

Different speeds may yield different finishing results. Experiment with trial-and-error to determine the best speed for your particular situation.

-26G9983 15" Open-End Wide-Belt Sander

Oscillation Return

The oscillation return keeps the sanding belt in motion. The valve shown in Figure 22 controls the oscillation return.

Air Eye

Fork

Limit Switches

The limit switches are mounted on both sides of the sanding belt. They are designed to stop the sander if the belt travels too far to one side of the top roller.

The limit switches are factory set and should require no adjustments. However, if they stop working correctly, they move during adjustments, or they get replaced, proper adjustments will be required.

To adjust the limit switches:

1.

Center the sanding belt on the top roller.

Measure the distance between the edge of the sanding belt and the limit switch lever.

This distance should be approximately 1 ⁄

2

". If this measurement is different, then loosen the adjustment bolts shown in Figure 23 on the incorrect side.

Oscillation

Return

Valve

Figure 22.

This is the oscillation return valve and the air eye fork.

To adjust the oscillation return:

1.

Turn off all power to the sander, but keep air pressure going into the machine. Lower the belt and slide it out of the way of the eye fork.

2.

Block the airflow between the eye fork until the top roller rotates to one side and does not return.

3.

With the airflow still blocked, loosen the jamnut on the valve knob and tighten the knob to close the valve.

4.

Now clear the eye fork so the air will flow between it again. Watch the top roller and slowly open the valve.

5.

When the top roller begins to move, open the valve another 1 ⁄

4 to 1 ⁄

2 turn of the knob.

Tighten the jamnut. DO NOT open the valve more than needed or there will be excessive pressure on the air system.

Figure 23.

Loosen these bolts to adjust the limit switch position.

2.

Slide the mounting bracket in the necessary direction until there is a 1 ⁄

2

" gap between the edge of the belt and the limit switch lever.

3.

Tighten the adjustment bolts to secure the mounting bracket. Test the sander to verify that operation returns to normal.

G9983 15" Open-End Wide-Belt Sander -27-

Pressure Roller

Depth

Variables such as feed rate, depth of the cut, and type of sanding belt can play a big part in determining the proper amount of downward pressure exerted by the rollers. Some experimentation may be necessary with pressure roller spring tension to achieve the desired results. However, under no circumstances should the pressure roller depth be set even, or higher than, the sanding rollers or platen.

To adjust the pressure roller depth:

1.

Unplug the sander!

2.

Joint and plane a 6" W x 36"L piece of wood, then rip it down the middle. This will give you two boards that are nearly the exact same thickness.

3.

Place one board along the length of the conveyor belt on the right-hand side so it is directly beneath both front and back pressure roller depth bolts. Place the other board on the left-hand side so it is directly beneath both front and back pressure roller depth bolts. Figure 24 shows the front left-hand and front right-hand pressure roller adjustment bolts.

Left-Hand

Pressure

Depth Bolt

Right-Hand

Pressure

Figure 24.

These are the pressure roller depth bolts at the front of the machine. The rear depth bolts are in the same location at the rear.

4.

With the air pressure connected, and the sanding belt installed and tensioned, raise the pressure rollers above the sanding belt rollers.

5.

Raise the conveyor until the the boards touch the sanding belt rollers. The rollers should evenly touch the boards at the same time.

6.

Turn the conveyor handwheel counterclockwise 1 /

8 th of a turn. This should lower the conveyor approximately .020" or .5mm.

7.

Lower each end of the pressure rollers so they barely touch the boards. Lock in place.

-28G9983 15" Open-End Wide-Belt Sander

Pressure Roller

Tension

Pressure roller tension is largely set by trial and error. If there is not enough tension, the workpiece will not pass through the sander evenly and may possibly be launched toward the operator. If there is too much tension, the feed belt will experience premature wear and the workpiece will pass through the sander sluggishly (if at all).

To adjust the pressure roller tension:

1.

Unplug the sander!

2.

Make sure the pressure roller depth is set correctly.

3.

Open both access doors and locate the pressure roller tension springs shown in Figure

25 .

4.

Turning the nut on the adjustment bolt clockwise will increase the tension and counterclockwise will decrease the tension.

A quick way to gauge that the spring tension is consistent is to measure the distance from the top of the nut to the the top of the adjustment bolt. If the board pulls to one side during sanding, loosen that side in small increments as needed.

Figure 25.

This is one of the four pressure roller adjustment bolts.

G9983 15" Open-End Wide-Belt Sander -29-

Feed Belt Tension

To adjust the feed belt tension:

1. Disconnect the sander from the power source!

2.

Move the emergency brake plate up and out of the way.

3.

Tension adjustments are made using the bolts located on the left and right side of the front conveyor roller as shown in Figure 26 .

4.

When tensioned properly you should not be able to lift the belt off the conveyor surface or slide it back and forth, and it should not slip.

5.

Perform the “Feed Belt Tracking” instructions to ensure that the tracking did not change during tensioning.

Feed Belt Tracking

To check the feed belt tracking:

1.

Turn the feed belt ON .

2.

If the belt moves to one side then you need to immediately stop the machine and adjust the belt tracking. If the belt tracks evenly, leave it alone.

To adjust the feed belt tracking:

1.

Unplug the sander!

2.

Use the adjustment bolts (one is shown in

Figure 26 ) to correct the tracking.

3.

Run the feed belt for a few minutes after the adjustment to allow the belt to move into its new position. When you are satisfied that the belt has finished moving, stop the feed belt.

4.

If more adjustments are necessary, experiment with how the movement of the adjustment bolts affects the belt tracking; do this until you can make the feed belt track evenly. Make sure you did not loosen the belt during the tracking process. If you did, adjust each side of one belt roller away from the machine, as evenly as possible.

-30-

G9983 15" Open-End Wide-Belt Sander

V-Belt Tension

The sanding belt is driven by two V-belts on the

Model G9983. The V-belts must have adequate tension for proper power transmission. Proper tension is usually achieved when the V-belts can be deflected no more than 1" with moderate finger pressure at the midpoint between the widebelt pulleys and the motor pulleys. The large cover on the right-hand side of the sander must be removed to access the V-belts and the sanding motor.

Thread the nuts shown in Figure 27 down to tighten the V-belts, or thread the nuts up to loosen the V-belts.

Replacing V-Belts

Inspect the V-belts closely; if you see any glazing, cracking or fraying, replace the belts. Always replace the two V-belts at the same time for proper power transmission.

To replace the V-belts:

1.

Disconnect sander from the power source and shut off air pressure.

2.

Loosen the top nut on the motor adjustment bolt shown in Figure 28 . Turn the bottom nut counterclockwise to raise the motor (or pry motor up with a scrap piece of wood) and loosen the V-belts.

Figure 27.

Turning these nuts allows you to raise/lower the motor to adjust the V-belts.

Always inspect V-belts for damage or deterioration when adjusting for tension. Should you find evidence of cracking, abrasion or damage from wood chips or other foreign materials, replace the belt immediately. Belt breakage may lead to mechanical damage or operator injury.

G9983 15" Open-End Wide-Belt Sander

Loosen the V-belt by using the adjustment nuts.

3.

When V-belts are sufficiently loose, slide them off of the motor pulley.

4.

To remove the V-belts from the roller pulley, the roller needs to be removed. Open the left-hand access door and remove the platen micro-adjust knob by loosening the setscrew that secures the face. The plate underneath the knob is secured to the casting by two setscrews—remove these. Figure 29 shows the knob and indicator plate removed from the casting.

Installation is the reverse of removal. If possible, have an assistant help you when installing the V-belts and the roller. Also, an assistant can be helpful on the other end of the roller when tightening the nuts on the roller shafts.

NOTICE

New V-belts will often stretch after moderate use. Check frequently after installation.

-32G9983 15" Open-End Wide-Belt Sander

Platen Graphite

The graphite sheet on the platen will wear out with use. Similar to the sanding belts, the graphite sheet is considered a “consumable” item and is not covered under the warranty. We recommend keeping replacements in your inventory to avoid downtime. To obtain replacements, use the part number in the back of this manual for ordering.

To replace the graphite sheet:

1.

Pull the platen from its bracket with the included platen puller tool.

2.

Remove the screws and hold-down bar that secure the graphite sheet to the platen.

3.

Install the new graphite sheet exactly the reverse as removal. Make sure that the graphite sheet is wrapped in the same direction as the old one.

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, use the diagram on page 38 to follow all lines and connections, and use the instructions below to investigate.

• Carefully inspect all air lines for cracks, tears or hardening. Replace faulty hoses.

• Check the air connections for leaks. A small amount of water in a questionable area will bubble if there is a leak.

• Make sure lines are not clogged. Remove a questionable line and blow through it as a test.

If you ever determine that a component in the air system is malfunctioning, DO NOT operate the sander. Fix the problem before resuming operation.

G9983 15" Open-End Wide-Belt Sander -33-

Replacing Brakes

The only regular maintenance to perform on the brakes is to keep the rotor clean. This is a simple process and can be performed by spraying both sides of the rotor with automotive brake parts cleaner. The brake rotor must be free and clean of any dust, dirt, oil or moisture.

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.

To check the brake pads:

1.

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

2.

Remove the four screws that secure the motor cover on the right-hand side of the machine. This will allow you to access the brake components.

3.

The brake pads consist of a metal plate with a composite pad. With a fine ruler, measure the thickness of the composite pad only. If one of the pads is below 1 ⁄

8

" (approx. 3mm), replace both.

To replace the brake pads:

1.

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

2.

Remove the nuts from the two mounting bolts. There are two snap rings on the mounting pins behind the bracket. Remove these.

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 as in Figure 33 .

Figure 33.

Removing caliper to replace brake pads.

4.

The brake pads are secured to the caliper with cap screws. One of these screws is easily accessible; the other can only be reached by disassembling the brake caliper. Do this and remove the cap screws to remove the brake pads.

5.

Remove the brake rotor and have it professionally resurfaced. For this, find a local machinist or auto supply store that regularly resurfaces brake rotors for automobiles. If visible cracks are present in the brake rotor, replace with a new one. Clean the rotor with automotive brake cleaner to remove any oil or dirt. Handle with a dry rag and install exactly the reverse of removal.

6.

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

Air System

Various functions on the Model G9983 are controlled through the air system. Since this is a complex network of hoses and valves, please take some time to familiarize yourself with each item so you can better understand your machine during adjustments.

The illustration below follows the air travel through the machine to familiarize you with how it works. Match the letters in the text with those in the illustration to learn more about each function.

1.

The air flows into the machine at the pressure regulator (A). This should be adjusted to

75 PSI.

2.

The solenoid valve (C) controls the brake caliper (B) when signaled by the emergency stop switch or the limit switches.

3.

The switching valve (E) controls the vertical cylinder (D) which raises/lowers the top roller

(M) to tighten/loosen the sanding belt.

4.

The valve (G) controls the air flow volume that goes to the air eye fork (F), which controls the belt oscillation return.

5.

The diaphragm (H) actuates the switching valve (I) depending on whether air is coming from the eye fork (F) or the pressure regulator (A).

6.

Switching valve (I) actuates the diaphragm

(J), which controls oscillation arm (K), which in turn, moves eccentric shaft (L), which makes top roller (M) shift back and forth to control belt movement during operation.

7.

Valve (O) controls the speed at which the belt moves back and forth.

8.

Knob (N) allows you to rotate the eccentric shaft (L) to balance the oscillation timing so it takes the belt the same amount of time to move in one direction as it moves in the other direction.
