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.

Additional Safety for Wide Belt Sanders

Serious injury or death can occur from getting hands trapped between workpiece and conveyor table and being pulled into machine, or becoming entangled in rotating parts inside machine. Workpieces thrown by sander can strike nearby operator or bystanders with significant force. 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.

FEEDING WORKPIECE. Placing fingers between

workpiece and conveyor can result in pinching injuries, or possibly getting trapped and pulled into sanding area of machine. DO NOT place fingers under bottom of workpiece while feeding it into sander.

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

POWER DISCONNECT. An accidental startup while changing sanding belts or performing adjustments or maintenance can result in entanglement or abrasion injuries. Make sure machine is turned OFF, disconnected from power and air, and all moving parts are completely stopped before changing belts, doing adjustments, or performing maintenance.

KICKBACK. Occurs when a workpiece is ejected out the front of sander at a high rate of speed toward operator or bystanders. To reduce risk of kickback-related injuries, always stay out of workpiece path, only feed one board at a time, and always make sure pressure rollers are properly adjusted below sanding roller. Never sand workpieces below minimum specifications listed in Machine Data Sheet.

AVOIDING ENTANGLEMENT. Tie back long hair, remove jewelry, and do not wear loose clothing or gloves. These can easily get caught in moving parts. Never reach inside machine or try to clear jammed workpiece while machine is operating. Keep all guards in place and secure.

SANDPAPER CONTACT. Rotating sandpaper can remove a large amount of flesh quickly. Keep hands away from rotating sanding drum(s) during operation. Never touch moving sandpaper.

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.

-12-

No list of safety guidelines can be complete. Every shop environment is different. Always consider safety first, as it applies to your individual working conditions. Use this and other machinery with caution and respect. Failure to do so could result in serious personal injury, damage to equipment, or poor work results.

Model G0866 (Mfd. Since 11/18)

SECTION 2: POWER SUPPLY

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.

or equipment damage may occur if machine is not properly grounded and connected to 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 specified circuit requirements.

This machine can be converted to operate on a power supply circuit that has a verified ground and meets the requirements listed below. (Refer to Voltage Conversion instructions for details.)

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

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.

For your own safety and protection of

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.)

Since this machine must be permanently connected to the power supply, an extension cord cannot be used.

A permanently connected (hardwired) power supply is typically installed with wires running through mounted and secured conduit. A disconnecting means, such as a locking switch (see following figure), must be provided to allow the machine to be disconnected (isolated) from the power supply when required. This installation must be performed by an electrician in accordance with all applicable electrical codes and ordinances.

Grounding Instructions

In the event of a malfunction or breakdown, grounding provides a path of least resistance for electrical current to reduce the risk of electric shock. A permanently connected machine must be connected to a grounded metal permanent wiring system; or to a system having an equipmentgrounding conductor. All grounds must be verified and rated for the electrical requirements of the machine. Improper grounding can increase the risk of electric shock!

Serious injury could occur if you connect machine to power before completing setup process. DO NOT connect to power until instructed later in this manual.

Extension Cords

Voltage Conversion

The voltage conversion MUST be performed by a qualified electrician. To perform the voltage conversion, rewire the motors to the new voltage, according to the provided wiring diagram. If the

diagram included on the motor conflicts with the one in this manual, the motor may have changed since the manual was printed. Use the diagram provided on the motor.

Note About 3-Phase Power: DO NOT use a static phase converter to create 3-phase power— it can quickly decrease the life of electrical components on this machine. If you must use a phase converter, only use a rotary phase converter.

You can find the Model G7978, a compatible phase converter from on our website at www.grizzly.com.

to 440V

Remove wire labeled "1" at 220V terminal of

transformer (see Figure 13) and connect it to 440V terminal.

The Model G0866 is prewired to operate on 220V power, but it can be converted for 440V operation using the optional conversion kit (Model G440VG0866), which contains two replacement overload relays. 440V conversion consists of:

1) disconnecting the machine from the power source, 2) moving a wire on the transformer from the 220V to the 440V terminal, 3) replacing the main and feed motor overload relays, and 4) rewiring the motors for 440V operation. Wiring diagrams are provided in the back of this manual beginning on Page 75 showing the Model G0866 wired for both 220V and 440V. Refer to these when following this procedure.

All wiring changes must be done by an electrician or qualified service personnel. If, at any time during this procedure assistance is needed, call Grizzly Tech Support at (570) 546-9663.

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:

Site Considerations

Weight Load

Refer to the 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.

Lifting & Placing

Do not attempt to lift or move this machine without using the proper lifting equipment (such as forklift or crane). Each piece of lifting equipment must be rated for at least 5000 lbs. to support dynamic loads that may be applied while lifting. Refer to Needed for Setup on Page 18 for complete list of needed equipment for setup and installation.

To lift and move machine:

3. Open lower access panels and remove (4)

lag screws and flat washers that secure machine to pallet (see Figure 27), then close panels.

Note: The holes these fasteners are removed

from will later be used to anchor machine to floor.

-22-

Model G0866 (Mfd. Since 11/18)

Anchoring machinery to the floor prevents tipping or shifting and reduces vibration that may occur during operation, resulting in a machine that runs slightly quieter and feels more solid.

If the machine will be installed in a commercial or workplace setting, or if it is permanently connected (hardwired) to the power supply, local codes may require that it be anchored to the floor.

If not required by any local codes, fastening the machine to the floor is an optional step. If you choose not to do this with your machine, we recommend placing it on machine mounts, as these provide an easy method for leveling and they have vibration-absorbing pads.

Lag shield anchors with lag screws (see below) are a popular way to anchor machinery to a concrete floor, because the anchors sit flush with the floor surface, making it easy to unbolt and move the machine later, if needed. However, anytime local codes apply, you MUST follow the anchoring methodology specified by the code.

Leveling

For accurate sanding results and to prevent warping the conveyor table, the sander frame MUST be leveled from side to side and from front to back on both ends.

Re-check the sander frame 24 hours after installation, two weeks after that, and then annually to make sure it remains level.

Leveling machinery helps precision components, such as conveyor tables, remain straight and ﬂat during the lifespan of the machine. Components on a machine that are not level may slowly twist due to the dynamic loads placed on the machine during operation.

IMPORTANT: Use only hand tools to secure machine to floor. Do not tighten with impact tools, which can permanently twist and bend components and pull a level machine out of alignment.

For best results, use a precision level that is at least 12" long and sensitive enough to show a distinct movement when a 0.003" shim (approximately the thickness of one sheet of standard newspaper) is placed under one end of the level.

To level machine:

1. Open lower access panels and use (2) lev-

15. Manually raise conveyer table and verify that board touches both pressure rollers before touching sanding belt.

16. Repeat Steps 14–15 on other side of conveyor belt.

Note: If board did not touch both pressure

rollers before touching sanding belt on either side, or if board was difficult to place between rollers and table, then pressure rollers MUST be adjusted before operation. See Page 58 for instructions.

17. Check sight glass shown in Figure 37 to make sure gear oil is present.

Minimum CFM for Model G0866: 3600 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 dust collection system to machine:

Fit a 5" dust hose over each dust port, and

secure them in place with hose clamps (see Figure 38).

using machine.

chips or lung damage from breathing dust, always wear safety glasses and a respirator when operating this machine.

Installs and tensions sanding belts. Adjusts

platen as necessary.

Checks pressure regulator is between 57-75

PSI.

Verifies outfeed clearance and support.

5. Adjusts conveyor table height to approximate

thickness of workpiece.

Puts on safety glasses and respirator.

7. Connects machine to power, starts both

sanding belt motors, and then feed motor.

Starts dust collector.

9. Feeds workpiece into sander by placing front

end on infeed side of conveyor table and supporting back end until workpiece engages with pressure rollers.

Note: During initial pass with new workpiece,

operator adjusts table height as necessary so workpiece only makes light contact with sanding belts and does not overload sander.

Workpiece Inspection

Some workpieces are not safe to cut or may require modification before they are safe to cut.

Before sanding, inspect all workpieces for following:

• Material Type: This machine is intended for sanding natural and man-made wood products. This machine is NOT designed to sand metal, glass, stone, tile, plastics, drywall, cement backer board, laminate products, etc.

Sanding improper materials increases risk of

respiratory harm to operator and bystanders due to especially fine dust inherently created by all types of sanding operations —even if a dust collector is used. Additionally, life of machine and sanding belts will be greatly reduced (or immediately damaged) from sanding improper materials or from exposure to fine dust created when doing so.

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

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

Sanding Workpieces

The sanding process is influenced by the feed rate, sanding depth, grit size and material type of sandpaper, platen position, and oscillation speed. We strongly recommend that you experiment with these variables, or research best practices for achieving your desired sanding results with the type of material you have. Also, to avoid unnecessary wear on belts, always make sure the workpiece has been surface planed with a jointer or planer before sanding.

Typically, no more than 0.020" (one full rotation of handwheel) of material should be removed during a single sanding pass. The maximum sanding depth can also be influenced by the thickness of the sanding belt, which can vary from 0.010" (fine sandpaper) to 0.060" (coarse sandpaper).

Attempts to remove too much material at one time can cause jamming, wood burning, rapid sandpaper wear or tearing, poor finish, short motor life, and belt slippage. The operator usually makes a pass, raises the table a little, and repeats until the entire surface is sanded to satisfaction. Before sanding, ensure you review Workpiece Inspection on Page 33 and put on the required safety glasses and respirator.

Note: It may take more than one pass to achieve the full sanding depth.

The overall sanding process consists of the operator starting sanding with the platen in the up position with a coarse grit sandpaper, such as #60, and then repeating this for subsequent grit sizes from #80–#100 until the workpiece is evenly smooth.

• Excessive Warping: Workpieces with excessive cupping, bowing, or twisting are dangerous to sand because they are unstable and unpredictable when being sanded. DO NOT use workpieces with these characteristics!

• Minor Warping: Workpieces with slight cupping can be safely supported if cupped side is facing table. On the contrary, a workpiece supported on bowed side will rock during sanding, and could cause kickback or severe injury.

-32-

The operator then sets the platen level with the drums using the platen height components (see Figure 48) and performs intermediate sanding passes using #100–#150 grit sandpaper. For the final sanding pass, the operator sets the platen in the down position and sands the workpiece using #180 grit or finer sandpaper. Refer to Adjusting Platen on Page 36 for more information about platen positions.

Note: These numbers are approximate values only. They are provided with the intent of giving you a "ballpark" idea of what to expect for material removal rates from this machine. Many additional factors can influence the maximum depth-of-cut or removal rates that can be achieved with each pass (i.e. oscillation speed settings, depth-ofcut taken on previous pass, actual hardness of workpiece, etc.), so do not be surprised if you experience slightly different results.

Sanding Tips

•

Avoid sanding a workpiece more than is

necessary, since doing so will unnecessarily decrease belt life and cost you more money over time.

Only sand with as slow of feed speeds as

•

necessary to meet your sanding goals. In other words, avoid running the sander faster than is necessary. Increasing feed speeds beyond the required level can decrease the quality of the finished product.

• DO NOT sand boards less than 12" long, 2" wide and 3/16" thick to prevent damage to the workpiece and the sander (see Figure 50).

12" Min.

⁄16" Min.

2" Min.

As a general rule, use the sanding drum for

•

the initial heavy sanding pass, then use a combination of the platen and drum for the intermediate pass, and the platen alone for the final sanding passes.

As a rule-of-thumb, sand with progressively

•

higher grit numbers in increments of 50 or less.

Replace sandpaper with a higher grit to

• achieve a finer finish (refer to Installing / Changing Sanding Belts on Page 35).

When making multiple passes on the

•

workpiece, avoid raising the conveyor table more than 0.015" (nearly one turn of the height handle or 3 touches of the Table Up key) per each pass.

• Reduce snipe when sanding more than one board of the same thickness by feeding them into the machine with the front end of the second board touching the back end of the first board (aka "Butt Feeding").

Figure 50. Minimum dimensions for sanding.

• Extend the life of the sandpaper by regularly cleaning the sanding belt (refer to Cleaning Sanding Belt on Page 44).

• DO NOT edge-sand boards. This can cause boards to kickback, causing serious personal injury, and cause damage to the conveyor belt and sanding belts.

Only use the amp load meter to keep the

•

motor from overloading—that is its main purpose. Avoid using the amp load meter to monitor how much material is being removed, as this can lead to problems, including belts loading, burning, and poor quality sanding results.

• Make sure to adjust platen position accordingly when changing grit sizes.

• The faster the feed rate you use, the faster your sanding belts will wear out.

• Feed boards into the machine at different points on the conveyor to maximize sandpaper life and prevent uneven belt wear.

Adjusting Platen

This sander is equipped with an adjustable platen (see Figure 54) with a graphite pad that is designed to be used during finish sanding to create a polished-type finish and to prepare the workpiece for orbital sanding or a finish coat.

Figure 54. Platen removed from machine.

The platen position allows for 3 basic types of sanding: up, even, and down, which are adjusted by rotating the platen height dial (see Figure 55) to the desired position. The platen height gauge indicates the current position of the platen.

Unlike the sanding belts, which typically produce short but deep scratch patterns, the platen produces long and shallow scratch patterns that create a smoother finish. Due to the cushionedconstruction, the platen is less likely to leave beltsplice or chatter marks.

-36-

Model G0866 (Mfd. Since 11/18)

However, we do not recommend lowering the platen depth more than 2mm (about one complete knob turn) or over-using the platen by expecting it to remove marks beyond its ability to do so, since this can reduce the life of the sanding belt and platen, and result in premature streaking.

Tip: Given the short life-span of most graphite pads, it is a good idea to keep replacement pads on hand.

Platen Up: The platen is raised above the level of the drums (typically set at 1.5mm UP), so only the sanding drums are making contact with the workpiece. This position is typically used for heavy sanding passes or dimensioning. The drums do all the work, but you will have a rough finish. Typically platens are used in this position

with #100 or coarser grit.

Platen Even: The platen is set level with the drums. This position is used for intermediate-finishing passes. The depth of cut should not exceed

0.010". This position typically uses #100–#150

grit.

Platen Down: The platen is set below the level of the drums so it is the primary contact point while performing finish sanding.

The platen should be lowered to 0.2 to 0.5mm (maximum) below the sanding drums, but not more than 0.2mm per pass. You can lower the platen up to 2mm below the drums for short intervals, but streaking, burn marks, and premature graphite/platen wear can occur if this setting is abused or over-used.

It is not necessary to use the table height handwheel or Table Up button to adjust the sanding depth during the final sanding pass—the platen movement alone will take care of the depth of cut. Typically the final-sanding pass position

uses #180 or finer.

Changing Feed Rate

The conveyor belt is variable-speed, and is controlled by the knob located on the front of the feed belt gearbox (see Figure 56).

Conveyor Feed Rate

Figure 56. Feed rate adjustment knob.

As a general rule, slower feed rates are more beneficial than faster feed rates since they allow a given belt the time it takes to remove more material. We recommend you always start with the slowest feed rate and only increase the feed speed as needed to meet your sanding goals. Be sure to always test the feed rate using scrap wood similar to your workpiece.

Softwoods typically require a faster feed rate than hardwoods; however, there is no definitive rule to follow when determining the best feed rate to use for any type of wood.

Also, keep in mind that an increase in feed rate will increase the amperage load for a given sanding depth. This means you need to use shallower sanding depths at higher feed rates to avoid overloading the sanding motor.

Reading

Using EMERGENCY

Amp Load Meters

The amp load meters (see Figure 57) are used to keep the motors from overloading during sanding operations. They should not be used as the main method for controlling sanding belt material removal rates—doing so can result in belt loading, burning, and even breaking—because there are many different variables that affect optimum removal rates and these will affect the amp load in different ways.

Amp Load

Meters

STOP! Plate

The EMERGENCY STOP! plate can help reduce the amount of damage to internal components during an emergency and can prevent operator injury. Pushing the EMERGENCY STOP! plate (see Figure 58) causes the disc brakes to stop the sanding belt motors, immediately halting the sanding belts.

EMERGENCY

STOP! Plate

Figure 57. Location of amp load meters.

Amp load is 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 may soon occur. Adjust the table height accordingly to reduce the load, and use the amp load chart near the meter to keep the amp load in the green, SAFE range during operation.

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

Keep amp draw within GREEN load range shown on the AMP LOAD CHART. If you operate machine in RED load range, motor damage may occur and will not be covered under warranty.

An operator should be careful when loading a workpiece not to trap fingers between the workpiece and conveyor table, but in the event that it might happen, the EMERGENCY STOP! plate can be pressed by the operator while their hands are otherwise engaged.

Keep sanding drum V-belts correctly tensioned (refer to Page 59) to ensure proper functionality of EMERGENCY STOP! plate. Otherwise, pulleys can slip when emergency stop brake is applied and not immediately stop machine in the event of an emergency!

Schedule

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.

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 mounting bolts.

• Worn or damaged sanding belts.

Worn or damaged wires.

•

Worn or damaged platen graphite pad.

•

Any other unsafe condition.

•

Weekly Maintenance

• Drain water in air filter collection cups

(Page 43).

• Empty and clean dust trap bowls (Page 43).

• Lubricate grease fittings on conveyor belt

roller axles and sanding belt axles (Page 42).

Monthly Check

• V-belt tension, damage, or wear.

• Clean/vacuum dust build-up from inside cabi-

net and off motors.

• Grease table elevation chain, leadscrews,

and sprockets (Page 42).

• Check gearbox sight glass for oil level. Fill

gearbox if oil is below sight glass (Page 42).

Lubrication

It is essential to clean the components before lubricating them, because dust and chips build up on lubricated components and make the components hard to move. Simply adding more grease to the components with built-up grime on them will not yield smooth moving components.

Clean the components in this section with mineral spirits.

All other bearings are internally lubricated and sealed at the factory. Simply leave them alone unless they need to be replaced.

The following are the main components that need to be lubricated:

• Grease Fittings

• Table Elevation Leadscrews, Chain and Sprockets

• Feed Motor Gearbox

Schedules are based on average use. Adjust lubrication according to your level of use.

DISCONNECT POWER TO MACHINE BEFORE CLEANING AND LUBRICATING COMPONENTS!

Yearly Check:

• Replace white moisture filters in air regulator.

Cleaning

Sanding Belt

To increase the working life of your sanding belts, clean them whenever they decrease in performance due to heavy loading of material. Use a Model D3003 PRO-STIK in Figure 71.

Cleaning Pad as shown

Pneumatic System

The air system is durable and reliable; however, components do wear with age. If you suspect that an item in your pneumatic system may be having problems, see the Pneumatic System Diagram on Page 66.

• Adjust regulator to approximately 75 PSI.

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

• Check air connections for leaks. A small amount of soapy 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.

Figure 71. PRO-STIK cleaning pad in use.

To clean sanding belt:

Set table to thickness of cleaning pad.

2. Run pad through sander two or three times.

DO NOT take too deep of a cut—belt should barely touch cleaning pad.

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 74, the emergency braking system will activate and stop the sander immediately.

Setting Correct Airflow.

Setting Correct Airflow

An adequate stream of air through the air fork gap is essential for proper oscillation (see Figure 75). 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 this air fork gap.

Servicing Platen

The platen graphite pad and felt pad should be inspected on a daily basis and replaced when they become worn or damaged.

Due to its function, it is very important for the graphite pad to be flat, smooth, and free of grooves or low spots. It is also important that no dust or chips get trapped between the graphite pad and felt pad of the platen.

3. Use platen removal tool, as shown in Figure 80, to remove platen from sander.

Platen

If surface defects are found, lightly hand-sand the platen to make the surface flat again. If surface defects are more serious, the graphite pad may need to be replaced. If you notice a lot of streaking, this can also be a sign that the graphite pad or felt pad needs to be replaced.

Checking/Adjusting

Table Parallelism

Table parallelism has been adjusted at the factory and should not require adjustment when the machine is new.

We only recommend adjusting table parallelism if absolutely necessary due to factors that may cause the factory setting to change. Adjusting the table parallelism can take a fair amount of patience.

IMPORTANT: DO NOT adjust the table unless you are having trouble sanding your workpiece to a uniform thickness and have eliminated all other possible causes. For instance, a sanding or conveyor belt that is unevenly worn should be replaced before adjusting table parallelism.

Table Elevation

Sprocket (1 of 4)

Figure 95. Location of table elevation sprockets

(1 of 4 shown).

If a table adjustment is needed, take precise notes on the positioning of the table elevation flanges, sprockets, and leadscrews by marking them. This will allow the original setting to be restored if needed.

The four corners of the table can be independently adjusted up or down to achieve parallelism with the frame by adjusting the elevation leadscrew flanges (see Figure 94) or repositioning the table elevation sprockets (see Figure 95).

5. Place wood block on edge of table, at rear left corner, then raise table until wood block just touches upper frame (see Figure 96). Do not allow table to squeeze or compress wood block.

Note: Make sure wood block does not touch

conveyor belt.

Wood Block

Located at Rear

Left Corner

— If the measurements from all corners in

Step 6 are exactly the same as the length of the wood block, measured in Step 4, the table is parallel to the frame and no adjustment is necessary. Remove wood block.

— If the measurement of any corner from

Step 6 is not exactly the same as the length of the wood block, measured in Step 4, the table is not parallel to the frame. DO NOT remove wood block. Proceed to Adjusting Table Parallelism.

same distance from upper frame, table is parallel and no further adjustment is necessary.

— If any of corners are still higher or lower

than corner with wood block by more than

0.003", you will need to adjust the elevation leadscrew sprocket at that specific corner of the table. Proceed to Step 6.

Checking/Adjusting

Pressure Rollers

The pressure rollers have been adjusted at the factory and should not require routine maintenance.

Ideally, the pressure rollers should be positioned slightly lower than the sanding drum. However, we recommend verifying this setting. If the pressure rollers are incorrectly adjusted, you can end up with burned sanding belts, streaking, and poor workpiece results.

4. Rotate a sanding drum by hand, and manu- ally raise table until you hear sandpaper just contact surface of wood. DO NOT continue to raise table beyond this point.

Close upper right access door.

Connect machine to power and make note of

workpiece thickness, then lower table 0.035". This is how much lower infeed and outfeed pressure rollers should be compared to sanding surface of sanding drum.

Note: Variables such as feed rate, depth

of cut, and type of sanding belt can play a big part in determining proper amount of downward pressure exerted by rollers. Some experimentation may be necessary to achieve desired results. However, under no circumstances should pressure rollers be set even with, or higher than, sanding rollers.

Check belt tension: each belt is correctly ten-

sioned when there is approximately deflection when it is pushed with moderate pressure, as shown in Figure 103.

To adjust conveyor belt tension:

1. DISCONNECT MACHINE FROM POWER!

Rotate both left and right adjustment bolts

(see Figure 113 on Page 62) equally to adjust conveyor belt tension. When tensioned properly, you should not be able to lift the conveyor belt off of table surface or slide it back and forth.

In addition, two guide wheels (see Figure 115) protect the conveyor belt from damage if the tracking is out of adjustment, by preventing it from rubbing against the inside surfaces of the conveyor table.

— Rotate adjustment bolts clockwise to

increase conveyor belt tension.

— Rotate adjustment bolts counterclockwise

to decrease conveyor belt tension.

Adjusting Conveyor

Belt Tracking

The conveyor belt is tracking properly when it stays centered on its rollers during operation and does not wander from side to side. The tracking is adjusted by rotating either the left or right conveyor belt tension adjustment bolt (see Figure 114), depending on the needs of the adjustment.

SHOCK HAZARD. Working on wiring that is con-

nected to a power source is extremely dangerous. Touching electrified parts will result in personal injury including but not limited to severe burns, electrocution, or death. Disconnect the power from the machine before servicing electrical components!

MODIFICATIONS. Modifying the wiring beyond what is shown in the diagram may lead to unpredictable results, including serious injury or fire. This includes the installation of unapproved aftermarket parts.

WIRE CONNECTIONS. All connections must be tight to prevent wires from loosening during machine operation. Double-check all wires disconnected or connected during any wiring task to ensure tight connections.

CIRCUIT REQUIREMENTS. You MUST follow the requirements at the beginning of this manual when connecting your machine to a power source.

WIRE/COMPONENT DAMAGE. Damaged wires or components increase the risk of serious personal injury, fire, or machine damage. If you notice that any wires or components are damaged while performing a wiring task, replace those wires or components.

MOTOR WIRING. The motor wiring shown in these diagrams is current at the time of printing but may not match your machine. If you find this to be the case, use the wiring diagram inside the motor junction box.

CAPACITORS/INVERTERS. Some capacitors and power inverters store an electrical charge for up to 10 minutes after being disconnected from the power source. To reduce the risk of being shocked, wait at least this long before working on capacitors.
