Ratchet wrench with extension 7/16”, 9/16” and 1/2” sockets 9/16” open-end wrench Flat blade screwdriver

Installing Drum Head

1. Lift the drum head a ssembl y out of t he box, and temporarily rest it crosswise on top of the stand. (If your stand has casters, make sure they are lock ed.)
Figure 5
T he d rum h ead i s heavy; u se
an assistant to help lift if needed.
2. Mount the knob to the height adjustment handle. See Figure 5. Tighten the hex nut against the handle base with a 9/16” wrench.
3. Rotate the height adjustment handle clockwise to raise the drum and free the wood support bloc k s.
4. Use a 9/16” socket wrench to remove the hex cap screws and flat washers which secure the plywood board s to the bottom of the sander base. Retain these screws and washers for step 6.
5. Posi tion the drum head assem bly on top of the stand so that t he four thr eaded holes of the base ali gn wi th the holes in the long rails of the stand (Figur e 6).
[NOTE:The four holes at the center of the long rails are not used with the 16-32 Plus.]
6. Fasten base to stand (from beneath) with the four screws and flat washers that you removed from the plywood boards. See Figure 6. Tighten the screws securely.
Figure 6

Installing Conveyor

1. Raise the sanding drum to its highest elevation by rotating the height adjustment handle (Figure 5) in a cl ockwise direction.
2. Install the c onveyor bed to t he base so that the conveyor mounti ng holes align with the holes in the base. Install four 5/16” hex washer head screws (A, Figure 7).
3. Insert plug of motor cord (B, Figure 7) into the control box rec eptacle.
Figure 7
10
IMPORTANT: The conveyor belt has been over- tensioned for shipping pur poses. It m ust be re-
tensioned before operating the sander! See “Conveyor B elt T ensi on/T r ac king” on page 16.
Infeed/Ou tfeed Tabl es (Optional
Accessory)
The sander should be bolted to the stand or a work table when using these table extensions. Maximum working load of a table is 35 pounds.
1. Install a bracket (A, Figure 8) to the two holes in the sander base with a 9/16” wrench, using two hex cap screws (B), two flat washers (C) and two flanged lock nuts (D). The bracket should be fl ush against the base. Make sure the slotted holes for mounting the table ar e facing up, as shown in Figure 8. Tighten the flanged lock nuts (D) against the insi de of the sander base.
2. Place the table (E, Figure 8) over the bracket and insert four carriage bol ts, (F) flat washers (G) and hex nuts (H), as shown.
Finger tighten only .
Figure 8
3. Position the table slightly below the conveyor belt surface for proper support of stock. To check position, place a straight­edge on one si de of the conveyor bed under the sanding drum and extending out over the table. Lower the sanding drum to securely hold the straight-edge in place. See Figure 9. Rai se the infeed/ outf eed table until the table surface is slightly below the conveyor belt surface. Tighten hex nuts (H, Figure 8) with a 7/16” wrench. Repeat this procedure for ot her si de of t able.
4. Install the other bracket and table to the opposite side of the base in the same manner.
NOTE: If after adjusting the infeed/outfeed tables, they are still too high for proper operation, t he bracket may not be “set.” To set the bracket, slightl y loosen the f langed hex nuts (D, Figure 8) and firmly push down on the bracket. Securely re-tighten the flanged hex nuts.
If the stock being sanded is bowed, warped or otherwise inconsistent, be sure the tables are lower than the top of t he conveyor bed.
If stock slips on the c onv eyor, the tabl es may be positioned too hi gh. Lower tabl es to all ow stock to remain in contac t wit h the conv ey or .
Figure 9
11

Dust Collection

Dust collection is mandatory for a safe work environment and extended abrasive life. The 16­32 Plus is equipped with a 4” du st c ollection por t at the top of the dust cov er . It is designed t o be used with standard 4” dust collection hose connected to a high volume dust collector (minimum 400 to 600 cfm).
A standard shop ty pe cani ster (16 gal . or l ar ger) can be used for short periods of sanding time but requires conv erti ng the hose size down t o 2­1/2”. An adapter i s available for converti ng to t he 2-1/2” hose (see “Optional Accessories” on page
26).

Installing Abrasives

An 80-grit abrasive strip is already installed on the drum of your sander, and one box of assorted grit Ready to W rap supplied. Page 25 offers information on the types of abrasive and their recommended uses.
Proper attachment of the abrasive strip to the drum is critical to achieving top performance from your drum sander. Abrasive strips do not have to be pre-m easured. The end of t he roll is first taper ed and attached to the left (out board) side of the drum. Then the strip is wrapped around the drum, and the second taper i s made for attachm ent to the right (inboard) side of the drum.
NOTE: When using Ready To Wrap abrasives, not all of the steps below are necessary. You can use the original abrasive strip mounted to the drum as a template for cutting your own stri ps.
TM
abrasives is al so

Figure 10
(not applicable to “Ready To Wrap” strips)
1. Mar k and cut a taper at one end of t he roll as shown in Figure 10. Because the t apered end should use al l of the l eft (outboar d) slot width, its end must be trimmed back as shown.
2. Squeeze the fastener lever (Figure 11) on the outboard end of drum, and insert the tapered end of the abrasive so that i t uses most of the width of the slot. Release the fastener l ever to securely hol d the strip end to the fastener.
3. Begin wrapping the strip around the drum. The tapered edge of the strip end should follow the edge of the dr um.
4. Continue to wrap the abrasive in a spiral fashion by rotati ng the drum with one hand and guiding the strip with the other (Figure
12). Successiv e windings of the strip should be flush with previ ous windings without any
overlap.
Figure 11
Figure 12
12
5. Mark the trailing end of the strip where it crosses the ri ght (inboard) end of the drum (Figure 13).
6. Remove the abrasive strip from the drum, and cut a taper as was done with the starting edge (see Figure 10). Note: The taper on the rem aining 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 2-4 .
8. You can use your f i ngers to work the i nfeed take-up fastener, but it will be more convenient to use the TUFTool supplied with your sander. Hol d the T UFT ool with t he red end pointi ng away from y ou (Figure 14) and insert its hook into the outside hole of the fastener lever (see Figure 16).
9. Lift the lever with the TUFTool, pulling the lever up until it touches the inside of the drum.
10. Turn the TUFTool counterclockwise and lower it ont o the abrasiv e strip, making sure it is holding t he paper tight (Figure 15).
Figure 13
11. Insert the t apered end of the abrasiv e strip into the slot and fastener. It may be necessary to trim the tapered end of the abrasive strip so that it does not “bottom out” against the i nsi de of the drum.
IMPORTANT: Leav e a gap – at least 1/ 8” – between the tapered strip and the closed end of the slot (Figure 15) to allow strip to be pulled into the fastener as needed. If necessary, trim the outside edge of the abrasive strip.
12. Hold the abrasive in place with your left hand, lift up the TUFTool and turn it clockwise while maintaining upward pressure. Slowly move the TUFTool away from you slightl y, then down, while easing it out of the hole. This rel eases the lever i n its proper positi on (Figure 16).
All abrasive strips will stretch in use and may stretch enough to allow the take-up lever to reach its lowest position so that it can not maintain tension on the strip. If this occurs, follow the abov e procedures to re-set the take­up lever.

Grounding Instructions

Electrical connections must
be made by a qualified electrician in compliance with all relevant codes. This machine must be properly grounded to help prevent electrical shock and possible fatal injury.
In the event of a malfunction or breakdown, grounding provi des a path of least r esistance f or 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 insert ed into a matching outlet that is properly installed and grounded in accordanc e wit h al l loc al codes and ordinances.
Do not modify the plug provided. If it will not fi t the outlet, hav e the proper outlet installed 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 conductor . If repai r or replac ement of the electric cord or plug is necessary, do not connect the equi pment-grounding conduc tor 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 i s properly grounded. Us e only three wire extensi on c or ds that have three-prong grounding plugs and three- pole recept acles that accept the tool’s plug.
Repair or replace a damaged or worn cord immediately.
As received from t he factory, your drum sander is intended for use on a 20 am p, 110V dedicated circuit, whic h has an outlet and a plug that l ook like the ones illustrated in Figure 17. A temporary adapt er, which looks li ke the adapter illustrat ed in Figur e 18, may be used to connect this plug to a t wo-pole recept acle, as shown in Figure 18, if a properly grounded outlet is not available.
The temporary adapter should only be used unt il a properly grounded out let c an be installed by a qualified electrician. This adapter is not applicable in Canada. The green colored rigi d ear, lug, or tab, extending from the adapter, must be connected t o a perm anent ground such as a properly grounded outl et box, as shown in Figure 18.

Extens ion Cords
If an extension cord is necessary, make sure the cord rating i s suitable for the am perage listed on the machine's motor plate. An undersize cord will cause a drop in line voltage resulting in loss of power and overheating.
The chart in Figure 19 shows the correct size cord to use based on cord length and motor plate amp rating. If in doubt, use the next heavier gauge. T he smaller t he gauge number, the heavier the cor d.

Dust Cover Latch

The dust cover latch prevents the dust cover from accident ally opening. To release the latch, press inward on t he dust cov er knob (D, Figure
21). This will cause the dust cover center to flex
and release the l atch. Note that the dust c ov er latch can be adj usted i n or out by loo sening the screw (E, Figure 21) .

Conveyor Belt Tension/Tracking

Conveyor bel t tension and trac king adjustm ents may occasionally be necessary during break-in and normal operation to compensate for belt stretching.
IMPORTANT: The conveyor belt has been over- tensioned for shipping pur poses. It m ust be re-
tensioned befor e operating the sander. Belt Tension: To adjust the tension of the
conveyor bel t, first adjust t he take-up scre w nut (Figure 22) on both sides of the conveyor to obtain approximately equal tension on both sides of the belt when taut.
Insufficient belt tension will cause slippage of conveyor belt on the drive roller duri ng sanding operation. The conveyor belt is too loose if it can be stopped by hand pressure appl ied directl y to the top of the conveyor belt.
Excessive belt tension can cause tracking problems and resul t in bent rollers, bent take-up brackets, and prem ature wearing of the bronze roller bearings or conveyor belt.
Belt Tracking: Adjustments to tracking are made while the conveyor belt is running. After the proper belt tension has been achieved, turn on the conveyor unit and set it at the fastest speed setting. Watch for a tendency of the conveyor belt to drift to one side of the conveyor. If t here is drifting, tighten the tak e-up screw nut (Fi gure 22) on the side toward which the belt i s drif ti ng, and l oosen the take- up scre w nut on the opposite side. NOTE: A djust the take­up screw nuts only 1/4 turn at a time. T hen allow time for the belt to react to the adjustments before proceeding further. Try to avoid over­adjustments.

3. Remove the four bolts attaching conveyor assembly to base. Lift up and slide c onv ey or out to the side of the machine.
4. Set conveyor on motor side and slide conveyor belt off the end of the conveyor bed.
5. Reverse process for installation of new belt.

Sanding Drum Alignment

The sanding drum must be aligned parallel to the conveyor bed for proper machine operati on. The sanding drum comes preset from the factory. If a problem with the drum alignment occurs, follow the instructions below.
First inspect the alignment 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.
3. Insert the gauge between the drum and conveyor bed at the outer end of t he drum (Figure 23) . W ith the dust cover open, l ower sanding drum whil e slowly rotating drum by hand until the drum lightly contacts the thickness gauge.
Figure 23
Figure 24
4. Remove thickness gauge and place under drum at the other end (Figure 24). If the drum does not cont act the thickness gauge to the same degree as the opposi te end of the drum, alignment is necessary.
To align the drum:
1. Loosen t he four 3/8” hex cap screws – t wo front, two rear (A, Fi gur e 25) . T his allows the entire drum carriage and shroud to be pivoted on two scre ws – one screw in front, one in back.
2. Lay the thickness gauge under the drum lengthwise (Fi gure 26). Rotate t he fine t une adjustment knob (B, Figure 25) until the drum contacts the gauge equally along its entire surf ace. Rot ate the knob cloc kwise to raise the outboard end of the drum, countercloc kwise to lower the outboard end of the drum. Use the height adjustment handle to raise or l ower the entire drum.
3. When drum is parallel to conveyor, tighten the four screws (A, Figure 25).
Figure 25
Figure 26

Fine-Tuning Drum Alignment

(for sanding boards wider than the drum) NOTE: Perform this alignment after you are
familiar with sander operation. This is an operational test.
When sanding boards wider than the drum, drum alignment is critical and must be exactly level to slightly high on the outboard end to prevent ridges from forming on the board. Always check t his on a piece of scrap wood, as follows, before sanding the work piece.
1. Test alignment with scrap wood roughly 6 inches wide and 20 to 30 inches long. In stall abrasive, turn on sander, and pass the board through the sander sideways so that the end of the board extends beyond the end of the drum.
2. Without changing drum height, rotate the board 180° and sand the same side.
3. If a ridge is vi sibl e where the drum ov erlaps, loosen the four screws (A, Figure 27) and raise the outboard end of drum by turning the fine tune adj ustm ent knob (B, Figure 27) slightly clockwise. Re-tighten the four screws.
4. Repeat process unti l t he ridge is elimi nated, and the entire board is sanded.
NOTE: Keep track of how many revolutions of the fine tune knob are needed t o change drum alignment for wider (over 16”) sanding. When sanding narrow stock (l ess than 16”) loosen the four screws (A, Figure 27) and turn fine tune adjustment knob counterclockwise same amount as initial wide sanding until drum is again parallel.
Important: O nly turn fine tune adj ustment knob when all four screws (A, Figur e 27) ar e loose.

Drum Height Control Adjustment

If the height control mechanism does not operate easily or smoothl y, or there i s excessiv e vertical movement or deflection of the drum carriage, perform the following adjustments:
Figure 27
1. W ith a 1/8” wrench, adju st all four studs by tightening the lock nuts (Figure 28), then loosening them 1/8 to 1/4 turn. If the lock nuts are set too tight, height control will not operate easily. If the lock nuts are too loose, excessiv e def lection of the outboard end of the drum carriage will r esul t.
2. Apply lubricant to front and rear areas of motor mount slide.
3. Push height adj ustment handl e (Figure 28) downward to set firmly on housi ng.
Figure 28
18
4. Loosen set screws on collar (Figure 28).
5. Slide c ollar upward against hou sing so that all vertical free-play of height adjustment screw is eliminated. An easy method of doing this is to use a block of wood on top of the motor mount slide and under the collar, while lowering the drum with the height adjustment handle. Lubricate around washers beneath handl e and above collar.

Tension Roller Alignment

The infeed and out feed roll ers are tensioned to provide downward pres sure on the workpiece to prevent sli ppage on the feed 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 from drum.
2. Loosen all f our hex nuts on the bearing bolt s (A, Figure 29). This will allow both tension rollers to drop to their lowest position. (NOTE: Figur e 29 only shows outboard end of drum. Adjustments must be made on both ends of drum.)
3. Lower sanding drum to where it c ontacts the conveyor bed. T hen raise the sanding drum by making 3/4 tur n of the height adjustm ent handle.
4. Tighten the four hex nuts (A, Figure 29). Both tension rollers are now positioned about 1/16” below the bot tom of t he sanding drum.

Tension Roller Pressure Adjustment

You can increase or decrease tension roller pressure by turning the screws on the tension roller brack ets (B, Figures 29 & 30).
Too much tension r oller pressure can result in a “snipe” mar k, which i s identifi ed as a visi ble li ne running across the width of the board and located approximately 2-1/4” f rom the 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 t ension roller.
Tension roller pressure can also be adjusted by raising the height of the rollers, as follows:
Figure 29
Figure 30
19
1. Repeat “Tension Roller Alignment” except raise the sandi ng drum only 1/4 turn of the height adjustment handle.
2. If both tension r oll ers are causing snipe t hen tighten all four hex nuts (A, Figure 29) 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 infeed tension roll er 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 .
lower the drum slightly more. However, a combination of several variables will determine the proper depth of cut to use, including the following:
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
1. T o establish drum height, position t he stock to be sanded under t he drum . Do NOT start drum.
2. Lower the drum to the stock thickness, making sure drum can be rotated by hand while contacting stock.

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.
Circuit Breaker
The sander is equipped with a mot or protective device (circuit breaker). The breaker will automatically shut the sander off when excessiv e current is consumed.
If the breaker is tripped, tur n the sander off and press the circ uit breaker button on t he motor to re-set.
Basic Operating Procedure
1. Set depth of cut.
2. Start drum.
3. Start conveyor and select feed rate.
4. Start dust collection system.
5. Feed stock through m ac hine.
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 mechanical depth of cut.
It may take some ex perimentati 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 good rule of thumb when sanding with grits finer than 80 i s to lower the drum so it contacts the workpiece but drum can still be rotated by hand. When using grits coarser than 80, y ou c an
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 posi tion.
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 stoc k to avoid kick-back and/or slippage.
NOTE: If motor heat s up during operat i on, dept h of cut may be too great for size of grit and/or feed rate may be too fast.

Tips for Maximum Performance

The versatility designed into the 16-32 Plus 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 restric t airflow as much as flexible tubing. Y’s and elbows will restrict airflow less than T’s. Also, a hose sm aller than 2-1/2” diameter shoul d not be used.
20
Multiple-Piece Sanding Runs
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 multiple piec es of similar thick ness. If there is a signif icant thickness difference, t he thinner pieces can slip on the conveyor belt if they do not contac t 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 . Bec ause 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 ti pping or rocki ng during sanding. (Af ter the crown has been rem oved and t he top is fl at, turn the stock ov er and sand the oppo site side. ) To avoid personal inj ury, t ake speci al c are 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 excessiv e 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 that when using abrasives finer than 80 grit the drum is in cont ac t with the wood but can still be spun by hand. If
there is room , angli ng t he stock on t he conveyor belt can also help. Slowing the conveyor feed when coming to a rail in the stock can help prevent a di p or goug e. Thi s all ows the abra siv e to work the wider width with less effort, and to achieve better consistency of the finished 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 drums). 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° (see Figure 31).
Figure 31
Angling the workpiece for stock removal provides other advantages, such a s les s l oadi ng of certai n 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 f eed 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.
Keeping the Machine Clean
For best results, make cleaning the machine 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 center of balance. 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.

Tracker Kit (98-0080)

Trackers dramatically reduce tracking adjust­ments 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 32.
1. Di sconnect power to sand er, and di sconnect motor cord from contr ol box r ec eptacle.
2. Raise drum as far as it will go.
3. Loosen the conv eyor 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 bed and slide it out of the sander. Turn c onveyor bed upsi de down. Be careful not to damage t he c onv ey or belt.
6. On t he underside of the convey or 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 closest 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 the Trac ker wi ll 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 bed right side up and re­position the bed onto the base. Re-attach the four mounting bolts and tighten. Caution: Be careful not to knock Tracker(s) out of conv eyor bed when turning conv eyor over.
10. Make sure all switches are off. Connect power to sander and plug i n m otor.
11. Tension conveyor belt using take-up screw nuts. If both Trackers are i nstall ed, it is very important to have equal tension on both sides of the conveyor belt. Tighten both 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 bel t whil e the conveyor is operat ing at full speed.
13. Make sure conveyor belt runs smoothly inside Tracker slot and that 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.

Maintenance

Lubricate all movi ng parts, such as threaded rods, washers, and bu shings. (Bearings are pre-sealed and requir e no lubrication.)
Before doing maintenance on
the machine, disco nnect it from the el ectri cal supply by pulling out the plug or switching off the main switch! Failure to compl y may cause serious injury.
For best results, perform the following recommended pr oc edur es on a monthly basis:
Lubricate conv eyor bushings and check for wear.
Clean sawdust from the abrasive strip and the conveyor belt.
Blow dust from motors and switches. Blow dust from inside of sandi ng dr um .
Check all set screws for tightness on parts such as bearings, conveyor and couplings.

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.
JET Abrasives are available in Ready-To-
TM
Wrap Ready-To-Cut pr e-marked box. Your JET dealer can recommend the best choice for your application.
Selecting Drum Abrasi ves
It is important to select the proper grit of abrasives for the type of sanding being performed t o achiev e maximum sanding resul ts. As with any sanding operation, first begin sanding with a coar ser grit, depending upon the roughness of the stoc k or t he amount of stock to be removed. Then progressively work toward finer grits. The chart (Figure 33) shows the general uses for the various grits. JET offers abrasives in the ten different grits shown – consult the stock num ber s on page 26 to or der .
The amount of stock to be removed i s a major consideration when choosing the grit grade to start with. Grit s 24, 36, 50 and 60 are prim arily designed for stock removal. Grits 24 and 36 will remove the m ost material in one pa ss, whether you are doing abrasive planing, cleaning up glued panels, or flatt ening stock. Grit s from 100 through 220 are primarily finishing gr its designed to remove the scrat ch pattern fr om the previous grit used. F or best results, nev er skip more than one grit grade when progressing through a sanding sequence.

any grit grades during the sanding process. In general, premi um quality abrasiv es will produc e 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 di r ec tions. Cleaning sticks are av ailable from your J ET dealer. When cleaning, also brush the stick crumbs from the drum while it is still rotating.
Always wear eye protection
while performing sandpaper cleaning, and take all precautions to avoid any contact of hands or clothing with uncovered rotating drums.
Cloth-backed abrasives can be cleaned by soaking in pai nt thinner or mineral spirits for 20 minutes to 1 hour, then u sing a brus h to rem ov e any build-up or burns. Dry the abrasive strips completely before using.
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 abrasive.
