1.0 IMPORTANT SAFETY

INSTRUCTIONS

WARNING – To reduce risk of injury:

1. Read and understand the entire owner's manual before attempting assembly or operation.

2. Read and understand the warnings posted on the machine and in this manual. Failure to comply with all of these warnings may cause serious injury.

3. Replace warning labels if they become obscured or removed.

4. This drum sander is designed and intended for use by properly trained and experienced personnel only. If you are not familiar with the proper and safe operation of a drum sander, do not use until proper training and knowledge have been obtained.

5. Do not use this drum sander for other than its intended use. If used for other purposes, JET disclaims any real or implied warranty and holds itself harmless from any injury that may result from that use.

6. Always wear ANSI Z87.1 approved safety glasses or face shield while using this drum sander. (Everyday eyeglasses only have impact resistant lenses; they are not safety glasses.)

7. Before operating this machine, remove tie, rings, watches and other jewelry, and roll sleeves up past the elbows. Do not wear loose clothing. Confine long hair. Non-slip footwear or anti-skid floor strips are recommended. Do not wear gloves.

8. Kickback occurs when the workpiece is thrown towards the operator at a high rate of speed. If you do not have a clear understanding of kickback and how it occurs, DO NOT operate this drum sander.

9. Wear hearing protection (plugs or muffs) during extended periods of operation.

10. Do not operate this machine while tired or under the influence of drugs, alcohol or any medication.

11. Make certain the switch is in the OFF position before connecting the machine to the power supply.

12. Make certain the machine is properly grounded.

13. Make all machine adjustments or maintenance with the machine unplugged from the power source.

14. Remove adjusting keys and wrenches. Form a habit of checking to see that keys and adjusting wrenches are removed from the machine before turning it on.

15. Keep safety guards in place at all times when the machine is in use. If removed for maintenance purposes, use extreme caution and replace the guards immediately after completion of maintenance.

16. Make sure the sander is firmly secured to the stand or work table before use.

17. Check damaged parts. Before further use of the machine, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting and any other conditions that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced.

18. Provide for adequate space surrounding work area and non-glare, overhead lighting.

19. Keep the floor around the machine clean and free of scrap material, oil and grease.

20. Keep visitors a safe distance from the work area. Keep children away.

21. Make your workshop child proof with padlocks, master switches or by removing starter keys.

22. Give your work undivided attention. Looking around, carrying on a conversation and “horseplay” are careless acts that can result in serious injury.

23. Maintain a balanced stance at all times so that you do not fall onto moving parts. Do not overreach or use excessive force to perform any machine operation.

24. Use the right tool at the correct speed and feed rate. Do not force a tool or attachment to do a job for which it was not designed. The right tool will do the job better and more safely.

25. Use recommended accessories; improper accessories may be hazardous.

26. Maintain tools with care. Keep conveyor and abrasives clean for the best and safest performance. Follow instructions for lubricating and changing accessories.

27. Turn off the machine before cleaning. Use a brush or compressed air to remove chips or debris — do not use bare hands.

28. Do not stand on the machine. Serious injury could occur if the machine tips over.

29. Never leave the machine running unattended. Turn the power off and do not leave the machine until it comes to a complete stop.

30. Remove loose items and unnecessary work pieces from the area before starting the machine.

31. Stand out of the path of workpiece when feeding a board.

32. Always feed stock against the rotation of drum.

33. Keep hands clear when feeding parts onto the conveyor. The part will be forced down as it begins to feed, causing a pinching action between the part and the conveyor table. Never reach into a running machine. Turn off sander, allow it to come to a complete stop, and disconnect from power, before attempting to retrieve parts from beneath the drum.

34. Pay particular attention to instructions on reducing risk of kickback.

35. Don’t use in dangerous environment. Don’t use power tools in damp or wet location, or expose them to rain. Keep work area well lighted.

6.3 Assembling stand

An open stand is provided standard with the JWDS2244 Sander. An open or closed stand is available as an optional accessory (separate purchase) for the JWDS-2550 Sander. Refer to the assembly instructions that accompany the stand.

6.4 Mounting sander to stand

The closed stand (for JWDS-2550) is oriented so that storage door is located at back of machine. Front/back orientation is not important on the open stand.

Use an assistant to help lift and

position sander atop stand.

1. Remove any screws holding sander to pallet,

and lift sander from crate.

2. Position sander atop stand so that six threaded

holes of base align with holes in stand rails. Insert provided screws and washers and tighten securely.

6.5 Handle and hose hanger

See Figure 6-3.

1. Install height adjustment handle (B) onto

spindle and tighten set screw.

2. Install hose hanger (C) with screws and

washers (C

1/C2

6.6 Folding infeed/outfeed tables

(OPTIONAL)

See Figure 6-3.

The sander must be bolted to the stand or a work table when using these table extensions. Maximum working load of each table is 35 pounds. Fasteners are provided with the extension tables.

NOTE: If using the folding feature of the infeed/outfeed tables, make sure your table or bench allows for such vertical drop at front and back.

To install infeed table:

1. Install front (F) fixed bracket to threaded holes in sander base with screws and washers (HP4/5). Make sure bracket is oriented as shown. Bracket must be flush against base.

NOTE: Long bracket mounts to front (infeed); short bracket to rear (outfeed).

2. Tighten screws (HP4).

3. Install eccentric cam (HP8) with screw and washer (HP6/7). Finger tighten only at this time.

4. Install left (G) and right (H) table brackets, using handles and washers (HP1/2/3).

Note: Handle (HP1) is adjustable – pull up and rotate on pin to more convenient position, then release allowing it to settle back onto pin.

5. Place infeed table (D) onto table brackets and secure with screws and washers (HP4/5). Finger tighten only.

Align infeed table with sander’s conveyor table as follows.

See Figures 6-3 and 6-4.

6. Place a straight-edge at one side of conveyor table under drum and extending out over infeed table. See Figure 6-4. You may wish to lower drum until it contacts the straight edge to hold it in place.

7. Raise infeed table until it evenly contacts straight edge. If needed, loosen four screws (HP4) beneath table and adjust table to level. Tighten screws.

8. Loosen screw (HP6) and rotate eccentric cam (HP8) until it contacts lip of table bracket. Do this on both sides of infeed table. This ensures infeed table will remain level with conveyor table each time it is returned to operating position. Tighten screws (HP6).

9. Install outfeed table using identical procedure as above.

TIP: It is often preferable to position infeed/ outfeed tables slightly below conveyor table surface, particularly if stock being sanded is bowed, warped or otherwise inconsistent. Also, if stock slips on conveyor, the tables may be positioned too high.

Figure 6-5 (hose and clamp not included)

6.8 Installing abrasives

Proper attachment of the abrasive strip to the drum is critical to achieving top performance from your drum sander.

An 80-grit, 3-inch wide abrasive is pre-installed on drum. Optional pre-cut (“Ready-to-Wrap”) abrasives of different grits are available; see sect. 14.0.

(TIP: If you are using an after-market abrasive, use a new JET-supplied abrasive as a template to quickly cut a new strip. Alternatively, a diagram is supplied in Figure 6-6 showing trim dimensions.)

Figure 6-4: infeed table alignment

6.7 Dust collection

Dust collection is mandatory for a safe work environment and extended abrasive life. The JWDS-2244/2550 is equipped with a 4-inch dust collection port. Secure a 4-inch dust collection hose to the port with a hose clamp (Figure 6-5), and connect to a high volume dust collector (minimum 550 CFM). Note: Dryer vent hose is not acceptable

for this purpose.

Keep hose clear of conveyor area by directing it over the hose hanger at rear of sanding head.

A standard shop type canister (16 gal. or larger) can be used for short periods of sanding time but requires converting the hose size down to 2-1/2 inch. An adaptor (not included) is required.

Figure 6-6: abrasive trimming

(not applicable to Ready-to-Wrap strips)

To install abrasive strip:

1. Press fastener lever (Figure 6-7) on outboard (left) end of drum, and insert tapered end of abrasive through slit in fastener, as shown. Align tapered edge of abrasive strip with left edge of drum. Insert enough strip so that the right edge aligns with the reference notch; this will ensure the proper length of strip to be secured at the opposite end of the drum.

Figure 6-7

2. Release fastener lever to secure end of strip.

3. Begin wrapping abrasive around drum. The tapered edge of strip end should follow as closely as possible to edge of drum.

4. Continue wrapping abrasive in spiral fashion by rotating drum with one hand and guiding strip with the other. See Figure 6-8.

Successive windings of strip must not have any overlap. They should be flush with previous windings or with a slight gap between.

Figure 6-8

5. Press inboard take-up lever (Figure 6-9) and insert trailing end of strip as far as it will go. If necessary, trim tapered end of abrasive strip.

6. Release inboard take-up lever to secure strip.

All abrasive strips will stretch over time as they are used, and may stretch enough to allow the take-up lever to reach its lowest position so that it cannot maintain tension on the strip. If this occurs, follow the above procedures to reset the take-up lever.

Figure 6-9

7.0 Electrical connections

All electrical connections must be done by a qualified electrician in compliance with all local codes and ordinances. Failure to comply may result in serious injury.

The JWDS-2244 and JWDS-2550 Sanders are rated for single phase, 115-volt power only. The

sander comes with a plug designed for use on a circuit with a grounded outlet that looks like the one pictured in Figure 7-1.

Before connecting to power source, be sure switch is in off position.

It is recommended that the sander be connected to a dedicated 20 amp circuit with circuit breaker or fuse. If connected to a circuit protected by fuses, use time delay fuse marked “D”. Local codes take

precedence over recommendations.

7.1 GROUNDING INSTRUCTIONS

This machine must be grounded. In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This tool is equipped with an electric cord having an equipment-grounding conductor and 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.

Do not modify the plug provided - if it will not fit the outlet, have the proper outlet installed by a qualified electrician.

Improper connection of the equipment-grounding conductor can result in a risk of electric shock. The conductor with insulation having an outer surface that is green with or without yellow stripes is the equipment-grounding conductor.

If repair or replacement of the electric cord or plug is necessary, do not connect the equipmentgrounding conductor to a live terminal.

Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded. Failure to comply may cause serious or fatal injury.

Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the tool's plug.

Repair or replace damaged or worn cord immediately.

This tool is intended for use on a circuit that has an outlet that looks like the one illustrated in Figure 7-

1. An adapter, shown in Figure 7-2, may be used to connect this plug to a 2-pole receptacle as shown in Figure 7-2 if a properly grounded outlet is not available. The temporary adapter should be used only until a properly grounded outlet can be installed by a qualified electrician. The green-colored rigid ear, lug, and the like, extending from the adapter must be connected to a permanent ground such as a properly grounded outlet box.

In Canada, the use of a temporary adaptor is not permitted by the Canadian Electrical Code, C22.1.

Figure 7-1

Figure 7-2

7.2 Extension cords

The use of extension cords is discouraged; try to position machines near the power source. If an extension cord is necessary, make sure it is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. Table 2 shows correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

8.0 Adjustments

8.1 Drum Height Control

Drum height and depth of cut are controlled by height adjustment handle (B, Figure 6-3). Rotating handle clockwise lowers drum, counterclockwise raises it. One revolution of handle will move drum approximately 1/16” (or 1/4 turn = approx. 1/64”), as shown on label below handle.

8.2 Depth scale

The depth scale indicates distance between bottom of sanding drum and top of conveyor belt. Adjustment is performed by “zeroing” the scale.

1. Unplug sander from power source.

2. With an abrasive strip on drum, lower drum to where it just contacts top of conveyor belt. Note: Make sure drum – not just tension rollers – contacts conveyor belt.

3. At this drum position, the depth scale pointer should align with zero mark on scale. If it does not, loosen two screws on scale and adjust scale until zero aligns with the pointer.

4. Retighten screws.

Depending on desired accuracy, you may need to repeat this process when installing different abrasive grits.

8.3 Depth stop assembly

(OPTIONAL)

NOTE: The depth stop assembly is optional for JWDS-2244, but included with JWDS-2550.

The depth stop nut (A, Figure 1) provides a hard stop at final sanding depth. It ensures that the operator will not sand too deeply when he/she wishes to make multiple pieces the same final thickness.

1. Rotate handle to position drum at final sanding depth according to scale. (Figure 8-1 shows 7/8-inch final depth as example).

2. Press button on stop nut to slide nut into general position, then rotate nut until it firmly contacts bottom of plate (B).

CAUTION: The stop nut is designed to be used below the plate to allow full support when nut contacts plate. Using it above the plate may cause deflection as nut pushes into it.

3. Raise drum and perform sanding operation. Depending on the workpiece, multiple passes may be needed until final depth is reached and stop nut is contacted.

If stop assembly will not be used, loosen left screw (C) and rotate plate (B) out of the way (see inset). This allows free drum movement.

Excessive belt tension can result in bent rollers, bent brackets, and/or premature wearing of bushings or conveyor belt.

8.4 Infeed/Outfeed Table Adjustment

(OPTIONAL)

The optional tables can be swung down to allow easier access for abrasive wrapping or other adjustments.

Loosen handles on each side, slide table away from machine and then down. See Figure 8-2.

Figure 8-2

8.5 Conveyor belt tension/tracking

Conveyor belt tension adjustment may be necessary during the break-in period to compensate for belt stretching.

8.5.1 Belt tension adjustment

1. Adjust take-up screw (Figure 8-3) with 5mm hex wrench. Do this on both sides of conveyor to obtain approximately equal tension on both sides of conveyor belt when taut.

NOTE: Insufficient belt tension will cause slippage of conveyor belt on drive roller during sanding operation. The conveyor belt is too loose if it can be stopped by hand pressure applied directly to top of moving conveyor belt.

A belt tracks correctly when it moves centrally on the conveyor rollers without drifting to either side. Tracking adjustments are made while conveyor belt is running.

1. Make sure proper belt tension has been achieved (see sect. 8.5.1).

2. Turn on conveyor and set to maximum speed. Watch for tendency of conveyor belt to drift to one side of conveyor. If it drifts, tighten or loosen take-up screw on either side (Figure 8-

3).

Note: Adjust take-up screw only 1/4 turn at a time. Allow time for belt to react to adjustments before proceeding further.

Avoid over-adjusting, as this may affect belt tension. If tension is affected, it may become necessary to use both take-up screws to accomplish tensioning and tracking.

8.5.3 Trackers

8.5.2 Belt tracking adjustment

The sander comes equipped with “Trackers”, ceramic guides that reduce the amount of adjustments needed to keep conveyor belt tracked (centered) on conveyor table. These guides have a magnetic backing to keep them in place. If a Tracker wears through, it can be reversed by turning it over. See sect. 11.0 Tracker Kit for more information about re-setting trackers.

8.6 Inspecting drum alignment

The sanding drum must be parallel to conveyor table for proper machine operation. The sanding drum comes pre-aligned from the manufacturer. If a problem with drum alignment should occur, follow the instructions below.

First, inspect the alignment with a gauge of some kind. The following procedure uses a steel straightedge as a gauge.

1. Unplug sander from power source.

2. Open dust cover and remove abrasive strip from drum.

3. Insert gauge (A, Figure 8-4) between drum and conveyor table at outboard side.

Figure 8-4: drum alignment

4. With dust cover open, lower sanding drum while slowly rotating drum by hand, until drum lightly contacts gauge. NOTE: Make sure drum contacts gauge, not just the tension rollers. Make a note of the measurement on the sander’s depth scale.

5. Remove gauge and place under drum at inboard side.

6. If drum does not contact gauge equally on both ends of drum, alignment is needed.

To align conveyor table with drum:

7. Loosen both table locks (B, Figure 8-4)

lower table at outboard end slightly by turning knob (C).

4. Repeat this process until the ridge is eliminated and entire board is sanded.

Note: When sanding narrow stock (less than 16”), return conveyor table to parallel position. Turn knob opposite direction until lock nut (D, Figure 8-4) is contacted. The lock nut provides a positive stop for table parallelism.

8.7 Tension roller adjustment

The infeed and outfeed rollers are tensioned to provide downward pressure on the workpiece to prevent slippage on the feed conveyor. Tension rollers have been set by the manufacturer, but should be inspected and may require adjustment as the sander receives use.

Improperly adjusted tension rollers (i.e. those set too high, rendering them non-functional) could allow kickback of pieces being sanded.

You can increase or decrease tension roller pressure by turning the screws on the tension roller brackets (Figure 8-5).

Loosen both table locks

before adjusting drum alignment. Failure to comply may cause damage to table.

8. Turn knob (C) to raise or lower outboard end of table. Follow directional marks on label: (+) to raise, (-) to lower.

9. Tighten table locks (B).

8.6.1 Fine-tuning drum alignment

Note: This is an operational test for sanding boards wider than the drum. Perform this procedure only after you have become familiar with sander operation.

When sanding boards wider than the drum, table alignment is critical and table must be adjusted exactly level to slightly lower on the outboard end. This will prevent any ridges from developing in the stock. Always check this on a piece of scrap wood, as follows, before sanding the workpiece.

1. Run a piece of scrap wood approximately 6” wide by 30” to 40” long through the sander sideways so that end of board extends past outboard side of drum.

2. Without changing drum height, rotate board 180° and sand the same side.

3. If a ridge is visible where the drum overlaps, loosen both table locks (B, Figure 8-3) and

Figure 8-5: tension adjustment screws

Too much tension roller pressure can result in a “snipe” mark, which is a visible line located near the end of the board and running across its width.

If snipe occurs on the leading end of board, adjust outfeed tension roller. If the snipe occurs on trailing end of board, adjust infeed tension roller.

9.0 Operations

Before using the drum sander, review the previous sections on initial set-up and adjustment. Before operating, make sure an abrasive strip is mounted and a proper dust collection system is connected.

9.1 Basic Operating Procedure

1. Establish depth of cut.

2. Start dust collection system.

3. Start sanding drum.

4. Start conveyor and select feed rate.

5. Feed stock through machine.

To feed stock through the sander, rest and hold board to be sanded on conveyor belt, allowing conveyor belt to carry board into drum. Once stock is halfway through, reposition yourself to outfeed side of machine to receive and control board as it exits.

and familiarity with the machine before doing finish work.

A combination of several variables will determine proper depth of cut to use, including the following:

1. Abrasive type and grit size.

2. Width of piece being processed.

3. Hardness of piece.

4. Feed rate of conveyor belt.

NOTE: The use of a carrier or backer board (not provided), is recommended for cuts 1/16” or less. This is a flat board, usually of wood or MDF, slightly larger than the workpiece and of even thickness, placed beneath the workpiece as it is fed through the sander. The workpiece may be attached to the carrier with rubber cement, carpenter’s tape or some other easily removable adhesive. However, some operators use a rubber or textured surface on the carrier to help stabilize the workpiece by simple friction.

Board will be forced down

against conveyor table as it begins feeding, causing pinching hazard. Keep fingers away.

Do not open drum hood until

drum comes to a complete stop.

9.2 Switch safety key

To prevent unauthorized use of sander, turn off switch and pull out safety key (Figure 9-1). Store key in a safe place. Key must be reinserted to start sander.

Figure 9-1: safety key

9.3 Setting depth of cut

Adjusting the drum sander for proper contact between abrasive and stock determines the depth of cut, which is controlled by the height adjustment handle.

It may take experimentation to determine proper depth of cut, given the variables of abrasive grit, type of wood, and feed rate. For best results, use scrap wood to practice sanding and to develop skill

9.4 Establishing drum height

A good rule of thumb when sanding with grits finer than 80:

1. To establish drum height, position stock under the drum. Do NOT start drum.

2. Lower drum to the stock thickness, making sure drum can still be rotated by hand while just contacting stock.

Do not start drum while in

contact with stock.

3. Without changing drum height, turn on conveyor and run the stock out from under the drum. Start sanding drum and sand stock at that same position.

4. With the drum operating, feed stock under the drum from the infeed side and against the rotation of the drum. Always maintain control of the stock to avoid kickback and/or slippage.

NOTE: If motor heats up during operation, depth of cut may be too great for size of grit and/or feed rate may be too fast.

For sanding with grits coarser than 80, you can lower the drum slightly.

Always maintain control of stock. Through practice you will learn the proper depth of cut considering the variables above.

9.5 Selecting SandSmart™ feed rates

A faster feed rate allows faster sanding but fewer revolutions of the drum per inch of sanding. A slower feed rate provides more revolutions of the drum per inch of sanding to allow a greater depth of cut and smooth sanding.

Begin experimenting with the feed rate set at about 40% to 50% of maximum. The best feed rate will

depend on a number of factors, including type of stock, grit and depth of cut used, and whether the stock is fed directly in line with the conveyor table or at an angle. If the drum motor is lugging down, if conveyor belt is slipping, or if you observe a ripple effect on the stock, slow the feed rate. If the finish is smooth and the machine is not overworking, you can experiment using a faster feed rate.

The SandSmart controller continuously monitors the load on the drum motor, and automatically regulates the speed of the conveyor motor to maintain the highest feed rate without overload.

When the red indicator light (see B, Figure 9-1) comes on, the SandSmart control has detected too great a depth of cut and/or too fast a feed rate.

If the load on the drum motor increases, the SandSmart control will decrease the conveyor feed rate and will stop the conveyor under extreme conditions. If the load on the drum decreases, SandSmart will increase the feed rate but will not increase it faster than the manual setting on the speed adjustment label.

The best and most consistent finish will be achieved if the conveyor does not change speed during operation.

This change in conveyor speed may affect the finish surface. If the finish is affected, make another sanding pass without changing any settings. If the finish is still affected, make adjustments by slowing the conveyor and/or decreasing the depth of cut and run the stock through again.

Also try a faster feed rate or less depth of cut if the stock you are working begins to show burn marks. With cherry, hard maple or other hardwoods, using a shallower depth of cut and a faster feed rate will help minimize burn marks. Slightly angling the stock as it is fed into the machine will also help prevent burning the stock.

Because of the wide range of variables, it is important to experiment with your specific conditions and make adjustments to achieve the optimum feed rate. If problems occur, first check and adjust the feed rate, referring to the “Troubleshooting” section in this manual.

9.6 Maximum performance tips

The versatility designed into the JWDS-series drum sander allows it to be used for a variety of tasks that will boost return on your investment. For example, it will speed up fine sanding work often done with slower, dust-generating hand sanders, and will achieve fine thickness adjustments not possible on some sanders. It can be used to surface figured woods – bird’s eye or curly maple, for example – which can be damaged if fed through a planer.

Learning how to use its adjustments and controls will allow you to fine-tune the machine for maximum results. The best results come from experimenting with different abrasive grits and machine

adjustments to fit the job at hand. Following is a list of useful tips which can help you improve performance of your sander.

9.6.1 Dust collection

When connecting dust collectors, remember that straight pipe will not restrict airflow as much as flexible tubing. Y’s and elbows will restrict airflow less than T’s. Also, a hose smaller than 2-1/2” diameter should not be used.

9.6.2 Multiple-piece sanding runs

When abrasive planing (or thickness sanding) a run of similar pieces that you want to have the same thickness, it is best to determine the thickness of the thinnest piece and process all pieces to that same thickness in one session. Be aware that the sander will remove cups and crowns in the workpiece; consider this when measuring and processing stock to the same thickness.

9.6.3 Simultaneous multiple pieces

When sanding multiple pieces simultaneously, make sure to stagger (step) the pieces across the width of the conveyor belt. This provides better contact with the tension rollers. Try to process only multiple pieces of similar thickness.

If there is a significant thickness difference, the thinner pieces can slip on the conveyor belt if they do not contact the tension rollers. Also note that pieces thicker than 3/4” should be longer than the minimum normally recommended to prevent tipping of the stock.

9.6.4 Edge sanding

When edge sanding, the sander will mimic the opposite edge of the stock which is lying on the conveyor belt. Because of this, it is important for the stock edge to have been ripped at the proper angle to the face before the sanding process. When edge sanding stock that is less than 3/4” wide or more than 2” high, it is good procedure to stack and clamp several pieces together to prevent them from slipping or tipping on the conveyor belt.

9.6.5 Sanding imperfect stock

When sanding stock with a cup or crown, place the crown up. This will stabilize the stock to help prevent tipping or rocking during sanding. After the crown has been removed and the top is flat, turn the stock over and sand the opposite side. To avoid personal injury, take special care when sanding stock that is twisted, bowed, or otherwise varies in thickness from end to end. If possible, support such stock as it is being sanded to keep it from slipping or tipping. Use extra roller stands, help from another person, or hand pressure on the stock, to minimize potentially hazardous situations.

9.6.6 Face frames and raised panel

doors

It is very important to have the proper abrasive contact when doing this type of sanding. If the machine is set to take an excessive depth of cut, the result can be a gouge or dip as the drum goes from sanding the rails at full width to sanding just a few inches of width on the stiles. To prevent this make sure, when using abrasives finer than 80 grit, that the drum is in contact with the wood but can still be spun by hand. If there is room, angling the stock on the conveyor belt can also help.

Slowing the conveyor feed when coming to a rail in the stock can help prevent a dip or gouge. This allows the abrasive to work the wider width with less effort, and to achieve better consistency of the finished surface.

9.6.7 Stock feeding angle

Some pieces, because of their dimensions, will need to be fed into the machine at a 90° angle (perpendicular to drum). However, even a slight offset angle of stock will provide for more effective stock removal. The optimum feeding angle for stock removal is about 60°.

Angling the workpiece for stock removal provides other advantages, such as less loading of certain areas of the drum due to glue lines or mineral streaks in the stock, more even wear of abrasive strips, potentially faster feed rates, and lighter loads on the motor. Note that to get the best final finish, however, the stock should be fed through the machine so it will be sanded in line with the grain of the wood on the final one or two passes.

10.0 User-maintenance

Before doing maintenance on the machine, disconnect it from the electrical supply (pull out the plug), unless indicated otherwise. Failure to comply may cause serious injury.

 Lubricate conveyor bushings as needed, and

check for wear.

 Lubricate elevating leadscrew (A, Figure 10-1)

as needed.

 Clean sawdust from abrasive strip and brush

dust from conveyor belt.

 Keep slide areas clean (B, Figure 10-1).

 Blow dust from motors and switches.

 Blow dust from inside of sanding drum, which

may cause vibration or offset the center of balance. (Leave your dust collector on when cleaning dust from the drums.)

 Check all set screws for tightness on parts such

as bearings, conveyor table, and couplings.

Figure 10-1

10.2 Drum maintenance

The drum should not require removal from the machine under normal circumstances. Should maintenance ever become necessary, the drum has been designed for easy removal and replacement.

1. Disconnect sander from power source/unplug.

2. Remove four socket head screws (C, Figure 10-

2).

3. Carefully lift out drum with coupling (D) attached.

10.1 Cleaning and lubrication

For best results, make cleaning the sander a regular shop procedure. Allowing excess build-up of dust and debris can adversely affect performance through loading of the abrasives, slippage on the conveyor table, and/or the accumulation of material inside the drums which can throw off the center of balance.

NOTE: Bearings are pre-sealed and require no lubrication.

 Brush the conveyor belt after cleaning

operations. If not cleaned, the conveyor belt could allow stock to slip during sanding operations.

Figure 10-2: drum removal

10.3 Conveyor belt replacement

10.4 Commutator brush inspection

1. Disconnect sander from power source/unplug.

2. Raise drum to highest position.

3. Remove infeed/outfeed tables, if installed.

4. Turn take-up screws (see Figure 8-3) on both sides of conveyor to relieve belt tension, and slide the driven roller fully inward.

5. Remove two (2) screws at inboard side which attach conveyor table to base.

6. Remove two (2) screws that attach conveyor table to drum alignment bracket (E, Figure 10-

3).

7. Loosen two table locks (F, Figure 10-3).

8. Lift up conveyor table and remove it from machine. Avoid tearing the belt on any edges underneath the conveyor table. Do not allow the Trackers to drop, as they may break.

9. Set conveyor on motor side and slide conveyor belt off end of conveyor table.

10. Install new belt along with trackers (see sect.

11.0), and re-install conveyor table. Tension and track the new belt.

Figure 10-3

Note: If conveyor belt continually tracks to one side of the machine, reversing the belt on the conveyor table may remedy the problem. To make sure the conveyor table is not twisted, place a level on the conveyor table. Level the machine if needed. If there is still a problem, proceed with the steps below:

Step 1: Check conveyor drive roller and driven roller to make sure they are parallel to surface of conveyor table. To do this, first center conveyor belt on the conveyor table. Then lay a straight-edge on the exposed edge of conveyor table on left (outboard) side, extending it over the roller. Note distance between roller and straightedge.

Step 2: Now repeat Step 1 on right (inboard) side of conveyor. Compare the measurements from side to side. If they are not equal, loosen one of the brackets that hold the roller in place. Tip this bracket until distance between roller and straight-edge are equal from side to side, then tighten bracket.

To maintain motor efficiency, inspect the two carbon brushes every two months, or more frequently if sander is heavily used. Stalling or loss of power may be a symptom of worn carbon brushes. If one brush is worn out, replace both at the same time.

Continued use of damaged or

worn brushes may result in damage to motor armature.

1. Disconnect sander from power source/unplug.

2. Unscrew and remove cap with flat blade screwdriver. See Figure 10-4.

3. Gently pry up an edge of the brass clip, until the spring causes it to disengage from hole. (Notice orientation of brush as you remove it; it should be inserted in the same manner; curvature of brush will match curvature of motor.)

4. Pull out brush and inspect. Brush should be replaced if any of the following are discovered:

 Brush has worn to about 1/2-inch long.

 Signs of crumbling, burning or breaking.

 End of brush is rough or pitted.

 Abnormal coloration of spring

 Broken lead in spring

 Collapsed spring

5. Install new brush (or reinstall current brush) and gently press it all the way into hole until the brass clip is secured.

6. Install cap.

7. Repeat for other brush.

NOTE: It is recommended that sander be run without load for several minutes to seat new brushes.

Figure 10-4

10.5 Additional servicing

Any additional servicing should be performed by an authorized service technician.

11.0 Tracker kit

Stock No.: PM2244-213

Trackers dramatically reduce tracking adjustments of conveyor belts. They are already installed on your sander. The following information is for resetting or replacing your trackers, should that become necessary.

1. Disconnect power to sander.

2. Raise drum as high as it will go.

3. Turn both conveyor take-up screws to relieve conveyor belt tension and slide driven roller fully inward.

4. Remove the 2 bolts and loosen 2 wing screws holding conveyor table to sander base.

5. Lift conveyor table and slide it out of sander. Turn conveyor table upside down. Be careful not to damage conveyor belt.

6. On the underside of the conveyor table, there are U-channels welded to the table. The Tracker is positioned on the inside of the first Uchannel on the infeed side of sander (Figure 11-

1). The back of tracker is magnetized and will stick to side wall of conveyor table. Do not install tracker if edge of conveyor belt is damaged or torn.

7. With first tracker installed, slide conveyor belt into bottom slot of tracker. Note: When installed properly, only bottom lip of tracker will be visible. The top slot can be used if bottom slot wears out.

8. Install second tracker opposite the first. Use both trackers unless the second one does not fit in conveyor or unless conveyor belt is damaged.

9. Turn conveyor table right-side up and reposition it onto sander. Re-attach three mounting screws and tighten. Caution: Be careful not to knock tracker(s) out of conveyor table when turning conveyor over. Trackers may break if allowed to fall.

10. Make sure all switches are off. Connect power to sander and plug in motor.

11. Tension conveyor belt using take-up screws. If both trackers are installed, it is very important to have equal tension on both sides of conveyor belt. Turn take-up screws on both sides until equal tension is obtained.

12. To check tension, turn on conveyor full speed and place both hands on conveyor. If conveyor belt can be stopped, continue tensioning until conveyor belt cannot be stopped by both hands on the belt while conveyor is operating at full speed.

13. Make sure conveyor belt runs smoothly inside tracker slot and that the magnet is holding the tracker in position.

14. Continue to watch tracking of conveyor and adjust only if necessary, making sure to keep equal tension on conveyor belt at all times and not allowing conveyor belt to buckle under conveyor table.

Figure 11-1: Underside of conveyor shown

12.0 Abrasives

The abrasive material you choose will have a substantial effect on the performance of your sander. Variations in paper type, weight, coating and durability all contribute to achieving your desired finish.

JET Abrasives are available in Ready-To-Wrap pre-cut lengths or in the convenient Ready-To-Cut pre-marked box. Your JET dealer can recommend the best choice for your application.

12.1 Selecting drum abrasives

It is important to select the proper grit of abrasive for the type of sanding being performed to achieve maximum results. As with any sanding operation, first begin sanding with a coarser grit, depending upon the roughness of the stock or the amount of stock to be removed. Then progressively work toward finer grits. The chart below shows the general uses for the various grits.

The amount of stock to be removed is a major consideration when choosing the grit grade with which to begin. Grits 24, 36, 50 and 60 are primarily designed for stock removal. Grits 24 and 36 will remove the most material in one pass, whether you are doing abrasive planing, cleaning up glued panels, or flattening stock. Grits from 100 through 220 are primarily finishing grits designed to remove the scratch pattern from the previous grit used. For best results, never skip more than one grit grade when progressing through a sanding sequence.

For fine work, such as furniture, try not to skip any grit grades during the sanding process.

In general, premium quality abrasives will produce a better finish with a less noticeable scratch pattern.

Note: Grits that are too fine can sometimes burnish the wood and leave a glossy surface which will not accept stains evenly. This will vary by type of wood. Oak, for example, is susceptible to burnishing because of its open pores.

12.2 Cleaning abrasive strips

Regularly clean the abrasive strip on the drum with commercially available cleaning sticks, following the manufacturer’s directions. When cleaning, also brush the stick crumbs from the drum while it is still rotating.

In some cases, heavily loaded areas can be removed with Plexiglas held on edge over the rotating drum.

Always wear eye protection while performing sandpaper cleaning, and take all precautions to avoid any contact of hands or clothing with the rotating drum.

Cloth-backed abrasives can be cleaned by soaking in paint thinner or mineral spirits for 20 minutes to one hour, then using a brush to remove any buildup. Dry the abrasive strips completely before using. Any used solvents should be discarded in compliance with environmental regulations.

12.3 Increasing abrasive life

Abrasive life can be increased not only by cleaning, but by removing the abrasive strip from the drum and reversing it. To do this, remove the strip and use what was the trailing end as the starting end on the left (outboard) side of the drum. Reversing the strip will provide a fresh set of cutting edges on the abrasive.

12.4 Abrasive selection guide
