It is designed to be used with standard 4” dust collection hose (B, Fig. 7) connected to a high volume dust collector (minimum 500 CFM) as shown.

JET offers a variety of Dust Collectors and Air Filtration Units. Contact your local distributor for more informati on.

Figure 7

Installing Abrasives

An 80-grit, 3-1/8” wide abrasive strip is already installed on the drum of your sander.

Proper attac hm ent of the abr asiv e stri p t o the drum is critical to achieving top performance from your drum sander. Abr asive strips do not have to be premeasured. The end of the roll is first tapered and attached to the left (outboard) side of the drum. Then the stri p is wrapped around t he dr um, and the second taper is made for attachment to the right (inboard) side of the drum.

Note: You can use the original abrasive strip mounted to the dr um as a templat e for cutting y our own strips.

1. Mark and cut a taper at one end of the roll as shown in Figure 8. Because the tapered end should use all of the left (outboard) slot width, its end must be trimmed back as shown.

2. Raise the fastener lever (D, Fig. 9) on the outboard end of drum, and insert the tapered end of the abrasive (E, Fig. 9) so that it uses most of the width of the slot. Release the fastener l ever to securely hold the str ip end to the fastener.

Figure 8

Figure 9

3. Begin wrappi ng the strip around t he drum. The tapered edge of the str ip end should follow the edge of the drum.

4. Continue to wrap the abrasive in a spiral fashion by r otati ng the drum with one hand and guiding the strip with the other (Figure 10).

Successive windings of the strip should be flush with previous windings without any

overlap.

Figure 10

5. Mark the trailing end of the strip where it crosses the right (inboard) end of the drum (Figure 11).

6. Remove the abrasiv e strip from the drum, and cut a taper as was done with t he starting edge (see Figure 8). Note: The taper on the remaini ng roll can be used as the taper for the starting edge of the next strip to be cut.

7. Rewrap the drum beginning at the left, as described in steps 2 through 4.

8. You can use your fingers to work the infeed take-up f astener, but it will be more c onvenient to use the TUF Tool suppli ed with your sander. Hold the TUFTool with the red end pointing away from you (Fi gure 12) and insert its hook into the out side hole of the fastener lever (see Figure 14).

9. Lif t the lev er with the TUFTool, pulli ng the lever up until it touches the inside of the drum.

10. Turn the T UFTool counterclock wise and lower it onto the abrasive strip, making sure it is holding the paper ti ght (Figure 13).

11. Insert t he tapered end of t he abrasive stri p into the slot and fastener. It may be necessary to trim the tapered end of the abrasive strip so that it does not “bot tom out” against the inside of the drum.

IMPORTANT: Leave a gap – at least 1/8” – between the tapered strip and the cl osed end of the slot (Fi gure 13) to allow stri p to be pull ed into the f astener as needed. If necessary, trim the outside edge of t he abrasive strip.

Figure 11

Figure 12

12. Hold t he abrasive in pl ace with your left hand, lift up the T UFTool and tur n it clockwise whil e maintaini ng upward pressure. Slowly move the TUFTool away from you slightly, then down, while easing it out of the hole. This releases the lever in its proper posi tion (Figure 14).

All abrasive strips will stretch in use and may stretch enough to al low 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 re-set the take-up lever.

Always remove TUFTool from machine before operating.

Grounding Instructions

permanent gr ound such as a properly grounded outlet box, as shown in Fi gur e 16.

Electrical connections must

be made by a qualified electrician in compliance with all relevant codes. This machine must be properly ground ed to help prevent electrical shock and possible fatal injury.

In the event of a malfunction or breakdown, grounding prov i des a path of least resistanc e f or electric current to reduce the risk of electric shock. This tool is equipped with an electric cord having an equipment-groundi ng c onduc tor and a grounding plug. The plug m ust be inserted into a matching outlet that is properly installed and grounded in accord ance wit h all l ocal codes and ordinances.

Do not modify the pl ug provided. If it will not fit the outlet , have the proper outlet i nstalled by a qualified elec trician.

Improper connection of the equipmentgrounding 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 equipmentgrounding conduct or. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment-grounding conductor t o 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 properl y grounded. Use onl y three wire ex tension cords that have three-prong grounding plugs and t hree-pole recept acles that accept the tool ’s pl ug.

Repair or replace a damaged or worn cord immediately.

As received f rom the factory, your drum sander is intended f or use on a 20 amp, 110V dedic ated circuit, whic h has an outlet and a plug that look like the ones ill ustrat ed i n Figure 15. The sander cannot be rewired to voltages other than f act ory settings.

A temporary adapter, which looks like the adapter ill ustrated in Figur e 16, may be used to connect this plug to a two-pole receptacle, as shown in Figure 16, if a pr oper ly grounded outl et is not available. The temporary adapter should only be used until a properly grounded outlet can be installed by a qualified electrician. This adapter is not applicable in Canada. The green colored rigid ear, lug, or tab, extending from the adapter, must be connected to a

Extens ion Cords

If an extension cord is nece s sary, make sure the cord rati ng is suitabl e for t he amper age listed on the machine's motor plate. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating.

Table 1 shows the correct size cord to use based on cord length and motor plate amp rating. If in doubt, use the next heavier gauge. The smaller the gauge number, t he heavier the cord.

Drum height is cont rolled by the height adjustment handwheel. Rotating the handwheel counter-

clockwise lowers the drum; clockwise raises it. One revolution of the handwheel moves the drum

approxim ately 1/16”.

Oscillator Switch

Referring to Fi gur e 18: The 22-44OSC sander can be operated as a

simple sander or as an oscillating sander. When operating as a linear sander, the sander

drum rotates as the convey or slides the workpiece through. W hen in the oscill ating mode, in addition to the operati on described, the sander drum head oscillates from left to right as shown in Figure 18.

For linea r sanding mode :

1. Sander must be turned off.

2. Pull the oscillator switch (A) OUT. Note: Before pulling the oscillator switch out for

linear sanding mode, turn the oscillator switch to manually position the sanding drum to center or where otherwise desired.

3. Turn machine on.

Figure 17

Figure 18

For oscillatin g san di ng mode:

1. Sander must be turned off.

2. Press oscillator switch (A) IN and at the same time rotat e the switch (either direction) until the pins (B) protruding from the oscillator switch shaft engage in the detent (C) of the pulley base.

3. Turn the feed rate control knob (E) fully clockwise.

Note: The feed rate must be set to maximum when in the oscillation mode.

4. Turn the machine on.

Adjustments

Depth Gauge

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

1. Loosen screw (A, Figure 19) sufficiently to allow the pointer (B) to be turned to depth gauge scale.

2. With an abrasive strip on the drum, lower sanding drum to where it touches top of conveyor belt.

3. At this drum position, the depth gauge pointer (B) should align with the zero mark of the scale. If it does not, loosen screw (A) and raise or l ower pointer t o align with z ero on the scale.

4. Re-tighten scr ew (A).

Note: Depending on t he desired accurac y, you may need to repeat t his process when installing different abr asive grits.

slippage of conveyor belt on the drive roller during sanding operation; the conveyor belt is too loose if it can be stopped by hand pres sure applied directly to the top of the conveyor belt. Excessive belt tension can result in bent rollers, bent brackets, and/ or premature wearing of the bushings or belt .

Tracking. Belt tracking adjustments are made while the conveyor belt is running. After the proper belt t ension is obtained (see abov e), t urn the conveyor on and set it at t he fastest speed setting. Watch for a tendency of the conveyor belt to drift to one side of the conveyor. To adjust tracki ng, tighten t he take-up screw nut on the side toward which the belt is drifting, and loosen the take-up screw nut on the opposite side an equal amount.

Adjusting t he take-up screw nuts on eit her side of the conv eyor allows belt t racki ng adjustment s to be made without aff ecting belt tension.

Note: Adjust tak e-up screw nuts only 1/ 4 turn at a time. Then allow time for the belt to react to the adjustments before proceeding further. Try to avoid over adj ustm ents.

Figure 19

Conveyor Belt Tension and Tracking

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

IMPORTANT: The conv eyor belt has been over- tensioned for the purpose of shipping. Before

operating the sander, adjust the belt tension according to the following instructions!

Tension. To adjust the tension of the conveyor belt, fi rst adj ust the t ake-up scre w nut (A, Fi gure

20) using the attached wrench (B, Figure 20).

Do this on both sides of the c onveyor to obtai n approxim ately equal tension on bot h sides of the belt when taut. Insufficient belt t ensi on will cause

Figure 20

Trackers

The sander comes equipped with “Trackers”, ceramic guides that reduce the amount of adjustments needed to keep the conveyor belt tracked (cent ered) on the conveyor bed. These guides have a magneti c backing to keep t hem in place. If a Tracker wears through, it can be reversed by turning it over. The Tracker Kit section on Page 22 contains more information about re-setting trackers.

Conveyor Belt Replacement

1. Unplug the machine from the wall receptacl e, and unplug the mot or cord from the control box r ec eptacle.

2. Raise drum to its hi ghest position using the handwheel.

3. Loosen the conveyor take-up screw nuts (A, Fig. 20) to relieve belt tension, and slide the driven roller fully inward.

4. Remove the four bolts that attach the conveyor table to the base. Lift up the conveyor t able and remov e it from machine. Avoid tearing the belt on any edges underneath the conveyor bed.

5. Install new belt, and re-install conveyor table. Take care not to damage the Trackers. T ensi on and trac k the new belt.

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

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

Step 2: Now repeat S tep 1 on the ri ght (inboard) side of conveyor. Compare the measurements from side to side. If they are not equal, loosen one of the brac kets that hold t he roller i n place. Tip this bracket until the distance between the roller and the straight-edge are equal from side to side, then tight en the bracket.

3. Insert gauge between the drum and conveyor bed at the outer end of the drum (Figure 21).

Figure 21

With the dust cover open, lower sanding drum while slowly rotating drum by hand until the drum lightly contacts the thic kness gauge.

4. Remove thickness gauge and place under drum at the other end.

5. If the drum does not contact the thickness gauge to the same degree as the opposite end of the drum, ali gnm ent is necessary.

To align the drum:

6. Loosen t he four 3/8” hex cap screws – two front, two rear (A, Fig. 22). This allows the entire drum carriage and shroud to be pivoted on two scr ews – one screw in f ront, one in back.

7. Lay the thickness gauge under the drum lengthwise. See Figure 23. Rotate the fine tune adjustment knob (B, Fig. 22) until the drum contacts the gauge equally along its entire surfac e. Rotate the knob clockwi se to raise the outboard end of the drum, countercl ockwise to lower the outboard end of the drum. Use the height adjustment handwheel to raise or lower the entire drum.

Checking Drum Alignment

The sanding drum must be aligned parallel to the conveyor bed for proper m achine operati on. The sanding drum comes preset from the factory. If a problem with the drum alignment occurs, foll ow the instructions below.

First inspect the ali gnm ent with a gauge of some kind. The following procedure uses a steel straight edge as a gauge.

1. Unplug sander fr om power source.

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

8. When drum is parallel to conveyor, tighten the four screws (A, Fig. 22).

Fine Tuning Drum Alignment

Tension Roller Alignment

Note: This is an operational test. Perform this

alignment after you have become familiar with sander operati on.

When sanding boards wider than the drum, drum alignm ent is critical and must be adj usted exactly level to slightly higher on the outboard end. This will prevent any ridges from developing in t he stock. Always check t his on a piece of scrap wood, as follows, bef ore sanding the work piece.

1. Run a pi ece of scrap wood a pprox im atel y 6” wide by 30” to 40” l ong through the sander sideways so that the end of the board extends past the end of the drum .

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

3. If a ri dge is vi sibl e where the drum ov erlaps, loosen the four screws (A, Fig. 22) and raise the outboard end of the drum by turning the fine tune adjustment knob (B, Figure 22) slightly cl oc k wise.

Important: Only turn fine tune adjustment knob when all four screws (A, Fig. 22) are loose.

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

5. Tighten the four screws (A, Fig. 23).

The infeed and outf eed rollers are tensioned to provide downward pre ssure on the workpiece t o prevent sl ippage on the f eed conveyor. Tension rollers are set at the factory, 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 kick-back of pieces being sanded.

1. Unplug sander from power source and remove abrasive (D, Figure 24) from drum.

2. Loosen all f our hex nuts on the bearing bolts (E, Figure 24). This will allow both tension rollers to drop to their lowest position. (NOTE: Figur e 24 only shows outboard end of drum. Adjustments must be made on both ends of drum.)

3. Lower sanding drum to where it just contacts the conveyor bed. Then raise the sanding drum by making 3/4 turn of the height adjustment handle.

4. Tighten the four hex nuts (E, Figure 24). Both tension rollers are now positioned about 1/16” belo w the bot tom of the sanding drum.

Note: Keep trac k of how many revolutions of the fine tune knob are needed to change drum alignment for wider (over 22”) sanding. When sanding narrow stock (less than 22”) l oosen the four screws (Figure 22) and turn fine tune adjustment knob counterclockwise the same amount as the initi al wide sanding so that drum is again parall el.

Figure 23

Figure 24

Tension Roller Pressure Adjustment

Drum Height Control Adjustment

You can increase or decrease tension roller pressure by turning the screws on the tension roller brack ets (Figure 25).

Figure 25

Too much tension r oller pressure can result in a “snipe” mar k, which is identified as a visi ble line running across the width of the board and located approx im ately 2- 1/4” f rom t he end of t he board.

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

Tension roll er pressure can also be adj usted by raising the height of the rollers, as follows:

1. Repeat “Tension Roller Alignment” except raise the sandi ng drum only 1/4 turn of the height adjustment handle.

If the height control mechanism does not operate easily or smoothly or there is ex cessive vertical movement or deflection of the drum carriage, perform the following adjustments.

1. Tighten all four lock nuts (A, Fig. 26) and then loosen them 1/8 to 1/ 4 turn. If the lock nuts are set too t ight, height contr ol will not operate easily . If the l ock nuts are too l oose, excessiv e deflection of the outboard end of the drum carriage will r esul t.

2. Thor oughly lubricate the mating surfac es of the motor mount slide (B , Fig. 26), and the height adjustment screw (C, Fig. 26).

Figure 26

2. If both tensi on roll ers are causing snipe t hen tighten all four hex nuts (E, Fig. 24) at this position.

3. If only outfeed tension roller causes snipe, only ti ghten rear (outf eed) hex nuts on each end of drum at this position, then raise sanding drum anot her 3/4 turn of the handle.

4. Press inf eed tension roller down to rest on conveyor bed and ti ghten front (infeed) hex nuts at this positi on.

This process sets the t ension roller assembl y at an angle provi ding less ten sion pressure on t he outfeed roller.

Operation

Before using your drum sander, review the previous pages in this manual on initial set-up and adjustment. In this section, you will learn how to operate the machine. Make sure an abrasive strip is mounted and a proper dust collection system is connected.

Basic Operating Procedure

1. Set depth of cut.

2. Start dust collec tion system.

3. Select linear or osci llating sanding mode.

4. Start drum.

5. Start conveyor and select feed rate. If oscillator is engaged, set feed rate to maximum speed.

6. Feed stock through m ac hine.

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

Setting Depth of Cut

Adjusting the drum sander f or the proper cont ac t between the abrasiv e and the stock determ ines the depth of cut. The depth of cut is controlled by the height adj ustm ent handwheel.

It may take som e experimentati on to determine the proper depth of cut, given the variables of abrasive grit, type of wood, and feed rate. For best results, use scrap wood t o pract i ce sanding and to develop skill and familiarity with the machine befor e doing finish work.

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

Do not start drum while in

contact with stock!

For sanding with gri ts coarser than 80, you can lower the drum slight ly .

Always maintain control of stock. Through practice you will learn the proper depth of cut considering t he v ari ables above.

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.

Note: If sanding wit h the oscill ator engaged, the feed rate must be set t o maximum speed.

Begin experimenting with the feed rate set at about 40% to 50% of maximum. The best f eed rate will depend on a number of factors, including type of stock, grit and depth of cut used, and whether t he stoc k is fed direc tly in line with the conveyor bed or at an angle. If the drum motor is lugging down, if the conveyor belt is slipping, or if you observe a ripple eff ect on the stock, slow down the feed rate. If the finish is smooth and the machine is not overworki ng, you can experiment using a faster feed rate.

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

1. Abrasive type and gri t size.

2. Width of the piece being processed.

3. Hardness of the piec e.

4. Feed rate of the conv ey or belt.

Establishing Proper D rum Height

A good rule of thumb when sanding with grits finer than 80 i s to place the stock to be sanded under the drum and lower drum until it contacts the stock. Drum should still rotate by hand. Without changing drum height, finish f eeding the stock under the sander.

Start sanding drum and sand the stock at that same positi on.

Figure 27

The best and most consistent finish will be achieved if the convey or does not c hange speed during operation. When the red indicator light (B, Fig. 27) comes on, the SandSmart control has detected t oo great a depth of cut and/ or too fast a feed rate.

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 f aster feed rate or less depth of cut if the stock you are work ing begins to show burn marks. With cherry, hard maple or other hardwoods, usi ng 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 al so hel p pr ev ent burning the stock.

Because of the wide range of variables, it is important to experiment with your specific conditions and m ak e adjustm ent s to achi ev e t he optimum f eed rat e. If pr oblems occur, fi rst c heck and adjust the feed rate, referring to the “Troubleshooting” sections in this m anual.

Tips for Maximum Performance

The versatility designed into the 22-44OSC drum sander allows it to be used for a wide variety of tasks that will boost the return on your investment. For example, its capabilities range from taking the place of a planer to thickness rough stock, to speeding up fine sanding work often done with slower, dust-generating hand sanders.

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 adj ustments to fit the job at hand. Following i s a list of useful tips which can hel p you improve performance of your sander.

Dust Collection

When connecti ng dust coll ect ors, remem ber that straight pi pe 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 shoul d not be used.

Multi pl e- Piece Sandi ng Run s

When abrasiv e planing (or t hickness sanding) a run of sim ilar pieces that you want to h ave 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.

Sanding Multiple Pieces At Once

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 multi ple pieces of similar thickness.

If there is a signif icant thickness difference, t he thinner pieces can slip on the conveyor belt if they do not cont act the t ension roll ers. Al so note that pieces thicker than 3/4” should be longer than the minimum normally recommended to prevent tipping of the stock.

Edge Sanding

When edge sanding, the sander will mimic the opposite edge of t he stock which is lyi ng on the conveyor belt . B ecause of this, i t is im port ant f or 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 t han 2” high, it is good procedure to stack and clamp several pieces together to prevent them from slipping or tipping on the conveyor belt.

Sanding Imperfect Stock

When sanding stock with a c up or crown, place the crown up. This will stabilize the stock to help prevent tipping or rocking during sanding. After the crown has been rem oved and t he top is fl at, turn the stock ov er and sand the opposit e side. To avoid personal inj ury, t ake speci al care when sanding stock that is twisted, bowed, or otherwise v aries in thi ckness from end t o end. If possible, support such stock as it is being sanded to keep it from slipping or tipping. Use extra rol ler stands, hel p from another person, or hand pressure on the stock, to minimize potentially hazardous situations.

Face Frames and Raised Panel Doors

It is v ery important t o have the proper abrasive contact when doing this type of sanding. If the machine is set t o 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 f ew inches of width on the sti les. 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, angli ng the stock on the conveyor belt can also help. Slowing the conveyor f eed when coming t o a rail in t he stock can help prevent a dip or gouge. T hi s all ows the abrasive to work t he wider width with l ess effort, and to achiev e bet ter c onsistency of the fi ni shed surface.

Stock Feeding Angle

Some pieces, because of their dimensions, will need to be f ed into the machi ne at a 90° angle (perpendicular to the drum). However, even a slight offset angle of the 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 a s les s l oadi ng of certain areas of the drums due to glue lines or mineral streaks in the stock, m ore even wear of abrasive stri ps, potenti ally faster feed rates, and lighter l oads on the m otor. Note that to get the best final finish, however, the stock should be fed through t he machine so it will be sanded in line wit h the grain of the wood on the fi nal one or two passes.

Leave the dust col lector on when c leaning dust from the drums. Also brush the conveyor belt after cleaning operations. If not cleaned, the conveyor belt could allow stock to slip during sanding operations.

For best results, perform the following recommended pr oc edur es on a monthly basis:

• Lubricate conveyor bushings and check for wear.

• Lubricate all movi ng parts, such as thr eaded rods, washers, and bu shings. (Bearings are pre-sealed and requir e no lubrication.)

• Clean sawdust from the abrasive strip and brush dust fr om the conveyor belt.

• Keep oscill ation roller and gib areas cl ean.

Maintenance

Before doing maintenance on the machine, disco nnect it f rom the electri cal supply by pulling out the plug or switching off the main switch! Failure to co mply may cause serious inj ury.

Keeping the Machine Clean

For best results, make cleaning the sander a regular shop procedure. Allowing excess buildup of dust and debris can adversely affect performance through the loading of the abrasives, slippage on the conveyor table, and/or the accumulation of material inside the drums which can thr ow off the c enter of balance.

• Blow dust from motors and switches. Blow dust from insi de of sanding dr um , which may cause vibration or offset the center of balance.

• Check all set screws for tightness on parts such as bearings, the conveyor, and couplings.

Tracker Kit

Stock No.: 98-0080A Trackers dramatically reduce tracking adjust-

ments of conveyor belts. They are already installed on your sander. The following information is for re-setting or replacing your trackers, should that become necessary. Refer to Figure 28.

1. Di sconnect power to sand er, and di sconnect motor cord from contr ol box r ec eptacle.

2. Lower conveyor table as far as it will go.

3. Loosen t he conveyor take-up screw nuts to relieve conveyor belt tension and slide driven roll er fully inward. Slide c onveyor belt to one side of bed.

4. Remove the f our bolts holding t he conveyor table to the sander base.

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

6. On t he undersi de of the c onveyor bed, there are U-channels welded to the bed. The Tracker is positioned on the inside of the first U-c hannel on the infeed side of sander (the U-channel c losest to the rubber covered drive roll er and gear m ot or). T he back of the Tracker is magnetized and will stick to the side wall of the convey or bed. Do not install Tracker if the edge of the conveyor belt is damaged or torn.

7. With the first Tracker installed, slide the conveyor belt into the bottom slot of the Tracker. Note: When install ed properl y, onl y the bottom lip of t he Tracker will be visible.

The top slot is to be used if the bottom slot wears out.

8. Install second Tracker opposite t he first. Use both Trackers unless the second one does not fit in conveyor or if conveyor belt is damaged.

9. Turn conveyor table right-side up and reposition it onto the sander. Re-attach the four mounting bolts and tighten. Caution: Be careful not to knock Tracker(s) out of conveyor bed when turning conveyor over.

10. Make sure all switches are off. Connect power to sander and plug i n m otor.

11. Tension the conveyor belt using take-up screw nuts. If both Trackers are i nstalled, it is very important to have equal tension on both sides of the conveyor belt. Tighten bot h sides of take-up screw nuts until equal tension is obtained.

12. To check tension, turn on conveyor full speed and place both hand s on conv eyor. If conveyor belt can be stopped, continue tensioning until conveyor belt cannot be stopped by both ha nds on the belt whil e the conveyor is operat ing at full speed.

13. Make sure conveyor belt runs smoothly inside Tracker slot and that the magnet is holding the Tr ac k er in positi on.

14. Conti nue to watch tracking of conv eyor 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 conv ey or bed.

Abrasives

The abrasive material you choose will have a substantial effect on the performance of your sander. Vari ations i n paper type, weight, coat i ng and durability all contribute to achieving your desired finish.

Selecting Drum Abrasi ves

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 am ount of stock to be rem oved. Then progressiv ely work toward finer grit s. The chart below shows the general uses for the various grits.

The amount of stock to be removed i s a major considerati on 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 sandi ng s equenc e.

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.

Cleaning Abrasive Strips

Regularly cl ean the abr asive stri ps on the drum s 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, build-ups resulting from burns can also 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 pai nt thinner or mineral spirits for 20 minutes to one hour, then using a brush to remove any build-up. Dry the abrasive strips completely before using. Any used solvents should be discarded in compliance with environment al r egulations.

Increasing Abrasive Life

Abrasive life can be increased not only by cleaning, but by r em ov ing 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. Rever sing the stri p will provi de a fresh set of cutting edges on the abr asive.
