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

collection port. Secure a 4-inch dust collection hose
(not provided) to the port with a hose clamp (see
Figure 5-2). Connect to a high volume dust collector,
minimum 400 CFM. Note: Dryer vent hose is not
acceptable for this purpose.
A standard shop canister vacuum (16 gal. or larger)
can be used for short periods of sanding time but
requires converting the hose size down to 2-1/2”. An
adaptor is required.
Figure 5-2 (hose and clamp not included)
5.6 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 strip is pre-installed
on the drum. Optional pre-cut (“Ready-to-Wrap”)
abrasives of different grits are also available; see
sect. 18.0.
(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 5-3 showing trim measurements.)
Figure 5-1: installing handle
5.4 Mounting to workbench
The sander should be bolted to a workbench or table
to avoid any tendency to creep or slide during
sanding operations. Use appropriate fasteners (not
provided) through the 4 slots in the machine base.
5.5 Dust collection
Dust collection is mandatory for a safe work
environment and extended abrasive life. The
JWDS-1020 is equipped with a 4-inch dust
Figure 5-3: abrasive trimming – (not applicable to
Ready-to-Wrap strips)
1. Rotate hood latch counterclockwise to open.
2. Press fastener lever (Figure 5-4) 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 5-4
3. Release fastener lever to secure end of strip.
4. Begin wrapping abrasive around drum. The
tapered edge of strip end should follow as
closely as possible to edge of drum.
5. Continue to wrap abrasive in spiral fashion by
rotating drum with one hand and guiding strip
with the other. See Figure 5-5.
Successive windings of strip must not have any
overlap. They should be flush with previous
windings or with a slight gap between.
Figure 5-5
6. Press inboard take-up lever (Figure 5-6) and
insert trailing end of strip as far as it will go. If
necessary, trim tapered end of abrasive strip.
7. 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 5-6
6.0 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-1020 Sander is rated at 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 6-1.
Before connecting to power source, be sure switch
is in off position.
It is recommended that the sander be connected to
a dedicated 15 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.
6.1 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.
9
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 6-
1. An adapter, shown in Figure 6-1, may be used to
connect this plug to a 2-pole receptacle as shown in
Figure 6-1 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.
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.

7.0 Adjustments
7.1 Drum Height Control
Drum height and depth of cut are controlled by the
height adjustment handle (see Figure 5-1). 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 the label below handle.
Figure 6-1
Figure 6-2
6.2 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
7.2 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 touches top of conveyor belt. Note:
Make sure drum contacts belt, not just the feed
rollers.
3. At this drum position, the (top edge of) depth
scale pointer should align with zero mark on
scale. If it does not, loosen screw (Figure 7-1)
and shift pointer to align with zero.
4. Retighten screw.
Note: Depending on desired accuracy, you may
need to repeat this process when installing different
abrasive grits.
10
Figure 7-1: depth scale adjustment
7.3 Conveyor belt tension/tracking
Conveyor belt tension adjustment may be
necessary during the break-in period to compensate
for belt stretching, and also after long-term use.
1. Make sure proper belt tension has been
achieved (sect. 7.3.1).
2. Turn on conveyor and set to maximum speed.
Watch for tendency of conveyor belt to drift to
one side of conveyor.
3. If conveyor drifts, slightly loosen two screws (A,
Figure 7-2) and turn take-up screw (B, Figure 7-
2) on one side of conveyor as needed.
Note: Adjust take-up screw only 1/4-turn at a
time. Allow time for belt to react to adjustments
before proceeding further.
4. When adjustment is satisfactory, tighten two
screws (A, Figure 7-2).
Avoid over-adjusting, as this may affect belt tension.
If tension is affected, if may become necessary to
use both take-up screws to accomplish tensioning
and tracking.
7.3.1 Belt tension adjustment
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. Excessive belt tension can
result in bent rollers, bent brackets, and/or
premature wearing of bushings or conveyor belt.
To adjust conveyor belt tension:
1. Slightly loosen four screws (A, Figure 7-2) on
infeed side of conveyor, with 4mm hex wrench
(two screws on each side).
2. Turn take-up screw (B, Figure 7-2) with 5mm
hex wrench. Do this on both sides of conveyor
to obtain approximately equal tension on both
sides of sanding belt when taut.
3. Tighten four screws (A, Figure 7-2).
4. Check conveyor belt tracking before operating
machine. Proceed to sect. 7.3.2.
7.4 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 hood and remove abrasive strip from
drum.
3. Position gauge (F, Figure 7-3) between drum
and conveyor table at outboard side of drum.
Figure 7-2: belt tension adjustment
7.3.2 Tracking adjustment
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.
Figure 7-3: drum alignment
4. With hood open, lower sanding drum while
11
slowly rotating drum by hand, until drum lightly
contacts gauge. NOTE: Make sure gauge is
contacted by the drum, 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.
7.4.1 Performing drum alignment
To align conveyor table with drum:
1. Loosen both table locking screws (C, Figure 7-
3) with 5mm hex wrench.
Loosen both table locking
screws before adjusting drum alignment.
Failure to comply may cause damage to
conveyor table.
2. To raise outboard end of table, loosen lock nut
(E, Figure 7-3) and rotate knurled nut (D, Figure
7-3) clockwise.
3. To lower outboard end of table, rotate knurled
nut (D) counterclockwise, and tighten lock nut
(E).
4. Verify setting using the gauge. Make further
adjustments using knurled nut as needed.
5. Retighten table lock screws (C).
7.4.2 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 work piece.
1. Run a piece of scrap wood approximately 6”
wide by 18 to 20” 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,
lower table at outboard end (see sect. 7.4.1).
4. Repeat this process until the ridge is eliminated
and entire board is sanded.
Note: When sanding narrow stock (less than 10”),
return conveyor table to parallel position.
7.5 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.
non-functional) could allow kickback of pieces
being sanded.
Tension roller pressure may be increased or
decreased by turning the screws on the tension
roller brackets (Figure 7-4) at each end of drum..
Figure 7-4: tension adjustment screws
Too much tension roller pressure can result in a
“snipe” mark, which is a visible line running across
the width of the board and located approximately 21/4” from end of board.
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.
8.0 Operations
Before using your 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.
8.1 Basic Operating Procedure
1. Establish depth of cut.
2. Start dust collection system.
3. Start sanding drum (with control panel switch,
Figure 8-1).
4. Start conveyor and select feed rate (with control
panel dial, Figure 8-1).
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.
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.
Improperly adjusted tension
rollers (i.e. those set too high, rendering them

8.5 Establishing drum height
To prevent unauthorized use of sander, turn off main
switch and pull out safety key (Figure 8-1). Store key
in a safe place. Key must be reinserted to start
sander.
Figure 8-1: control panel
8.3 Circuit breaker reset
If the sander becomes overloaded, the built-in
breaker will trip to help protect the motor. Allow the
machine to cool down, then push the reset button
(Figure 8-1) to restart.
If overloading happens frequently, refer to
Troubleshooting, sect. 11.0.
8.4 Setting depth of cut
Adjusting the drum sander for proper contact
between abrasive and stock determines the depth
of cut. The depth of cut 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
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. Some
operators use a rubber or textured surface on the
carrier to help stabilize the workpiece by simple
friction.
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.
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.
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 sect. 11.0,
Troubleshooting.

8.6 Maximum performance tips
8.6.5 Sanding imperfect stock
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.
8.6.1 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.
8.6.2 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.
8.6.3 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.
8.6.4 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.
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.
8.6.6 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.
8.6.7 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.
14
9.0 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.
9.1 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 accumulation of material
inside the drums which can throw off the center of
balance.
Leave the dust collector on when cleaning 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.
NOTE: Bearings are pre-sealed and require no
lubrication.
Lubricate elevating leadscrew (A, Figure 9-1) as
needed.
Clean sawdust from abrasive strip and brush
dust from conveyor belt.
Keep guide bars clean (B, Figure 9-1).
Blow dust from motor vents and switch area.
Blow dust from inside of sanding drum, which
may cause vibration or offset the center of
balance.
Check all set screws for tightness on parts such
as bearings, conveyor table, and couplings.
2. Loosen two screws on the coupling (D, Figure
9-2).
3. Carefully slide drum out of coupling and remove
from machine.
Figure 9-2: drum removal
9.3 Conveyor belt replacement
1. Disconnect sander from power.
2. Raise drum to highest position.
3. Loosen two screws (E, Figure 9-3) and turn
take-up screws (F, Figure 9-3) on both sides of
conveyor to relieve belt tension, and slide the
driven roller fully inward.
4. Loosen two table locking screws (G, Figure 9-
3).
5. Remove lock nut (G, Figure 9-3).
6. Remove two socket head screws that attach
conveyor table to base.
7. Lift up conveyor table and remove it from
machine. Avoid tearing the belt on any edges
underneath the conveyor table.
8. Set conveyor on motor side and slide conveyor
belt off end of conveyor table.
9. Install new belt and re-install conveyor table.
Check alignments, and tension and track the
new belt.
Figure 9-1
9.2 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. Remove two socket head screws (C, Figure 9-
2) on the bearing block.
Figure 9-3
15
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.
9.4 Commutator brush inspection
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.
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.
Continued use of damaged or
worn brushes may result in damage to motor
armature.
1. Unplug sander from power source.
2. Unscrew and remove cap with flat blade
screwdriver. See Figure 9-4.
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.)

10.0 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.
10.1 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.
TM
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.
10.2 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, heavy 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.
10.3 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.
10.4 Abrasive selection guide
