7. The table (U) should be positioned even with or

slightly below the conveyor belt surface. To
check position, place a level or straightedge
near the left si de of the conveyor and extending
out over the table, as shown in Figure 8. Raise
the conveyor table until the drum holds the
straightedge in place, and adjust the infeed
table until it is even with or slightly below the
conveyor belt surface.

8. Place the str aightedge near the the right side of

the conveyor table and repeat. T ighten all hex
nuts on the infeed table.

9. Mount the outfeed table in the same manner as

described above.
Note: Remov al of exi sting screws on t he rails

will not be necessary for the outfeed side.

Leveling the Sander

Proper leveling is important for getting the
maximum performance from your sander.

1. Place the unit where it will be used in the shop.

2. Mark t he positi on of the legs on the fl oor with

tape so the sander can be ret ur ned to the same
position.

3. Place washers on the casters as needed to

shim up the legs.

Dust Collection

Dust collection is mandatory for a safe work
environment and extended abrasive life. The
sander is equipped wit h a 4” dust collection port at
the back of the dust cover. It is designed to be used
with standard 4” dust c ollection hose connected t o
a high volume dust collector with a minimum
capacity of 600 CFM.

Using a shop v acuum is not recomm ended for this
machine, but if used it should be a 16 gallon or
larger canister type shop vacuum. This requires
converti ng the dust port do wn to 2-1/ 2”. An adapt er
is avail able from your dealer (stock no. 80- 2910) for
converti ng to the 2-1/2” hose. Do not reduce hose
size smaller than 2-1/2”. For best results, follow
recommendations of the dust collector
manufacturer.

Installing Abrasives

An 80-grit abrasiv e strip is already installed on the
drum of your sander. P age 28 of f ers i nformati on on
the types of abrasiv e and their recommended uses.

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 the drum, and the
second taper is made for attachment to the right
(inboard) side of the drum.

Note: When using JET Ready-To-Wrap
abrasives, not all of t he steps below are necessary .
You can use the ori ginal abrasiv e strip mounted t o
the drum as a template for c utti ng y our own strips.

1. Mark and cut a taper at one end of the roll as

shown in Figure 9. Because the tapered end
should use all of the left (outboard) slot width,
its end must be trimm ed back three inches as
shown.

2. Squeeze the f astener lever (Figure 10) on the

outboard end of drum, and insert the tapered
end of the abra sive so that it uses most of the
width of the slot . Release the fastener lever t o
securely hold the strip end to the fastener.

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 11).
Successive windings of the strip should be
flush with previous windings without any
overlap.

5. Mark the trailing end of the strip where it

crosses the right (inboard) end of the drum
(Figure 12).

6. Remove the abrasive str ip from the drum, and

cut a taper as was done with t he starting edge
(see Figure 9).

Note: The taper on the remaining roll can be
used as the taper f or the starting edge of the
next strip to be cut.

7. Rewrap the drum beginning at the left, as

described in steps 2-4.

Figure 12

8. You can use your fingers to work the infeed

take-up f astener, but it will be more c onvenient
to use the TUFTool (Y, Fig. 13) supplied with
your sander. Hold the TUFTool with the red
end pointing away from you (Figure 13) and
insert its hook into the outside hole of the
fastener lever (see Figure 15).

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 14).

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 closed end
of the slot (Fi gure 14) 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.

12. Hold t he abrasive in pl ace with your left hand,

lift up the T UFTool and t urn it clock wise while
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 15).

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 i t cannot mai ntain 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.

shock. This tool is equipped with an electric c or d
having an equipment-grounding conductor.

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

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

Repair or replace a damaged or worn cord
immediately.

As received f rom the factory, your drum sander
is wired for 230 volt. The sander cannot be
rewired to voltages other than factory settings.

It is recom mended that the sander be connected
to a dedicated, minimum 20 amp circuit with a
20 amp cir cuit breaker or tim e del ay fuse. Local

codes take precedence over recommend­dations.

If an extension cord is necessary, 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 i n loss
of power and overheating.

Figure 16 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.

Adjustments

Dust Cover

To access the drum, lift the front of the dust
cover using t he handle and push back the front
cover all the way to secure it in open po sition.
The dust port should be on t he back or outfeed
side of the sander.

When removing the dust cover for initial drum
alignment or other reasons, lift the front cover
half-way and pull the dust cover out from the
outfeed side of sander. The edges will pop out
when the dust cov er is pulled from t he carriage
leg brackets. Reverse thi s procedure t o re-install
the dust cover.

The dust cover should not require removal for
fine tuning alignments or for changing or
cleaning the abrasives.

Table Height Control

Note: Read Table Support Screws (page 9)

before operating the handwheel.
The table hei ght and depth of cut are c ontrolled

by the height adjustment handwheel (see
Figure 4). Rotating the handwheel raises or
lowers both side s of the t able simult aneously by
transferring the handwheel rotation through the
miter gear and tr ansfer r od assembly.

Check the operation of the height adjustment
mechanism. If it does not operate smoothly or
easily, check the following:

• The set-screws in the table supports have
been loosened and readjusted (see Table
Support Screws page 9) .

• The sander has been lev eled (Leveling the
Sander – page 11).

• Moving parts of the height adjustment
mechanism are well lubricated, including
miter gears, columns, and threaded
adjusting screws (Maintenance – Page 26).

If the table height mechanism still does not
operate smoothly, try the following:

1. Fur ther loosen the set-scre ws on the f ront of
the table supports (see Figure 3).

2. Lubricate thoroughly.
Apply penetrating lubricant to the table

supports where they contact the columns
and to all contact poi nts of adjusting screws
and transfer r od (see Features on page 7).
Also apply grease to the miter gears.

adjusting screw supports can be adjusted by
loosening the set- scre ws which secur e them
to the colum ns, and rotating the supports to
proper positi on.

4. Check the miter gear alignment.
The miter gears can be adjusted on their

shafts by prying off their pr otective caps with
a flat blade screwdriver, and loosening the
set-screws on the gears. Check that the
gear mesh is not too ti ght or too loose, and
that the gear teeth align with the opposing
gear. Note that the collars located on the
transfer rod (see Features, page 7) should
be positioned to control the lateral
movement of the transfer rod to maintain
accurate mit er gear ali gnm ent and mesh.

The mesh of the miter gears should be
smooth and even. If it is not, adjust the
gears for good mesh. Test for smooth
operation.

5. Next, check the position of the height
adjustment screws.

First raise the conveyor table. Then check
the retaining ring at the top of the height
adjustment screw on the outboard side
(Figure 17) , and the ret aining r ing under t he
height adjustment handle on the inboard
side of the machine. Both retaining rings
should be snug on their r espect ive bearings.

If there is a space between the retai ning ring
and the bearing, tighten one set-screw in
each of the table supports before performing
the following adjustment:

6. If one height adjustment screw is loose:
Remove the m iter gear f rom the t ransf er rod

on that side. T urn down the threaded hei ght
adjustment screw rod unti l it is snug. Make
sure both sides are snug on top and
retaining rings under the adjustment screw
supports are in place. Re-install the miter
gear. Loosen the set-screws in the table
supports and test for smooth operation.

3. If the height adjustment still feels stiff:
Check for misalignment of adjusting screw

supports and table supports which could
cause binding on the adj usting screws. The

Dept h Gauge/Depth Stop

Depth Gua ge

The depth gauge (A A, Figur e 18) measures the
distance between the conveyor table and the
sanding drum for thickness dimensioning of
boards.

Depth Gau ge Ca librat io n

1. Loosen the locking knob (BB) of the lower
depth gauge support (CC) and lower it so
that it rests on top of t he table support (EE).

2. Raise the conv ey or table until it touches the
sanding drum. Then loosen the l ocking k nob
(DD) of the upper depth gauge support and
position t he “0” mark of the scale even with
the top of the lower depth gauge support.

3. Tighten the upper depth gauge support in
position.

Once calibrated, the locking knob (BB) of the
lower depth gauge support can be loosened,
allowing the lower depth gauge support to ride
on top of t he table support. T he depth can then
be read where the scale enters the lower depth
gauge support.

Depth Sto p

The depth gauge can also be used as a stop
gauge as follows: Position the lower depth
gauge support (CC) al ong the scal e to a d esired
finish thickness. Then tighten the lower depth
gauge support wit h the locking knob to prev ent
the conveyor table f rom being r aised abov e that
point.

Digital Scale

Description

The digital scale can be used to measure the
distance between the conveyor table and the
sanding drum (Absolute measurement) for
thickness dim ensioni ng of boar ds. It can al so be
used to display the am ount of material rem oved
from a sanded board without consideration of
the board's thic k ness (Relative measurement).

Figure 19 ident ifies the part s of the digital scal e.
The button functions are discussed below,
followed by a section giv ing practical examples
of how to cal ibrate your sett ings, and how the se
functions can be used for daily sander
operations.

Before using t he device, wipe down the v ertical
scale with a dry, soft cloth. Do not use cleaning
solutions. Do not allow any liquids (such as
machine oil) to contact the body of the digital
display. K eep the devic e cl ean.

This devic e uses a 1. 5-volt batter y cell (SR44 or
G-13A). If it needs replacing, slide off t he battery
cover and insert the battery, with the positive
pole of the batt er y faci ng out.

Note: After replacing a battery, the digital
display setti ng defaults to z ero and needs to be
reset as described in the Setting the DRO
sections.

ON/OFF

Press ON/OFF button no l onger than 3 second s
to power on.

Press ON/OFF button at least 3 seconds to shut
off the digit al displ ay .

Setting the DRO – Absolut e Measu rement

Setting the DRO sets the distance from the
conveyor table to the sanding drum (Absolute
measurement) which represents the thickness of
the sanded board.

1. Take a board of arbitrary thickness , sand it
and measure the thickness with a caliper.
Make note of this measurement for use
below.

2. Without moving the table, press the SET
button on the DRO – t he indicator will fl ash
“SET”.

3. Press and hold the SET butt on.

Each digit will flash in turn. When the digit
you want flashes, release the S E T button.

4. Press SET button once (no longer than 1
second) and that digit will increase by one
each time SET is pressed.

16

When finished:

5. Press and hold the SET butt on until indicator
“SET” flashes,

6. Press SET again (no longer than 1 second).
The indicator “SET” disappears and the
value you just i nput is displ ay ed on the LCD.

From this point on, any table movem ent will be
based off this setti ng. The setting will be kept in
the device’s memory, even when the digital
display is turned off and only needs resetting
after a battery has lost charge and needs
replacing.

LCD

turn it off while in absolute (“ABS”) mode, your
absolute setti ng will default to zero.

MM/INCH

Pressing this button toggles back and forth
between standard (inches) and metric (mm), and
can be done at any t ime wit hout affecting sav ed
settings.

HOLD

The Hold button is used to record a critical
setting for reference for the purpose of later
resetting to that same setting.

For exam ple: In the event that sanding a board
is aborted in the middle of the operation:

1. Press the HOLD button. The dimension is
"frozen" in t he displ ay.

2. Lower the table to r em ov e the board.

3. Make a mental note of the "frozen"
dimension (f r om St ep 1).

4. Press HOLD again to return to normal
measurements.

5. Adjust the table back to its original (frozen
display) position.

Setting the DRO – Relative M easurement

Periodically during sanding operations, it may be
desirable to di splay the am ount of mat erial t o be
removed from a previously sanded board.

With the sander at t he last thickness sett ing for
that board:

1. Press ABS until "INC" appears. This toggl es
the DRO from Absolute to Relative mode.

2. Press the O N/O FF button f or less than three
seconds. The digital display resets to zero.

Raising the table will represent the
additional material to be sanded from a
board from the pr ev ious setting.

3. To toggle back to Absolute mode, press
ABS again.

IMPORTANT: Always place the di gital display in

relative (“INC”) mode before t urning it off. If you

This function is not generally used in sanding
operations, but is here explained for reference.

Press TOL, and an up-arrow indicator will
appear, as well as a flashing “SET” indicator.
You can now change the upper tolerance limit.
Hold down the TOL button and each digit
flashes in turn. When the digit you want flashes,
release the TO L butt on.

Press TOL button once (no longer than 1
second) and that digit will increase each time
TOL is pressed.

When finished, pr ess and hold TOL butt on until
indicator “SET” flashes. While indicator “SET” is
flashing, press SET button to change the arr ow
to the down-arrow indicator. You can now
change the lower tolerance limit in the same
manner as you changed the upper tolerance
limit.

When finished setting the lower tolerance limit,
while indicator “SET” is flashing, press SET
button (no longer than 1 second). T he device i s
now in tolerance m easuring mode. When the up­arrow indicator is displayed, it means the
measured value i s beyond the upper limi t. When
the down-arrow indicator is displayed, the
measured value is below the lower limit. When
the display shows an “OK” indicator, the
measured value is within tolerance.

Drum Alignment

The sanding drum must be aligned parallel to the
conveyor table for proper machine operation. The
sanding drum has been pre-aligned at the factory
and should not require immediate adjustment,
although it is recommended that you confirm the
alignment before operat ing the sander. P roceed as
follows:

First inspect the alignment with a gauge of some
kind. The following pr ocedure uses a steel strai ght­edge as a gauge. See Figure 20.

1. Unplug sander fr om power source.

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

3. Insert the gauge between the drum and
conveyor bed at one end of the drum (Figure

21). Raise the conveyor bed while slowly
rotating drum by hand until the drum lightly
contacts the t hic k ness gauge.

4. Move thickness gauge to the opposite end of
the drum. If the drum does not contact the
thickness gauge equally at both ends of the
drum, alignm ent is necessary. See below.

Figure 20

Initial Drum Alignment

1. Release v- belt tension from motor by loosening
pinch bolt of mot or support (Figure 21).

2. Loosen t wo lower #10-32 screws i n belt guard
(Figure 21 shows one of the screws). Slide
motor support up the column and re-tighten
pinch bolt.

3. Because the tension roller suspension
assembly (Figure 22) mounts to the drum
bearing bolts which are used to adjust the
drum, it is necessary t o align the sanding dr um
and tension rollers at the same time. Loosen
outboard bearing bolt knobs (Figure 22) and
the inboard bearing bolts.

4. With all four bearing bolts loosened, note that
the drum will adjust about 1/2” on each end.
Position dr um alignment tem plates (Figure 22)
on the conv eyor and below the drum with one
template at eac h end of t he drum.

5. Raise the conveyor bed so that the drum is
resting on both t emplates but leaving the dr um
within its range of adjustment. To check this,
you should be able to lift either end of t he drum
off the tem plates and, wit h light hand pre ssure
on the drum, attempt to slide tem plates with a
screw driver to make sure drum is actually
resting on the t em plate and not just in its lowest
position.

Figure 21

Figure 22

6. In t his position, t he drum should be resti ng on
the templates and both tension rollers resting
on the conveyor surface. Re-tighten bearing
bolts and restore v-belt tension. Tighten pinch
bolt in motor support and tighten two lower
screws in belt guard (Figure 21).

18

Fine-Tuning Drum Alignment

The 22-44 Pro-3 is equipped wit h a drum adjuster
mechanism that allows easy fine tuning or
changing of drum alignment without repeating the
intial drum alignm ent procedure.

1. Raise drum adjustment lever (Figure 23) so
that it just engages the side of drum carriage
leg.

2. Slightly l oosen bearing bolt k nobs. (An internal
tooth lock washer is placed under the head of
each bearing bolt to prevent tension rollers
from dropping out of position if knobs are
loosened slightly. If tension rollers do drop,
simply raise to a position equal to that of the
inboard end of the drum and slightly tighten
knobs.)

3. With the bearing bolt knobs slightly loosened,
raise drum adjustment lever to raise the
outboard end of drum, or lower drum
adjustment lever to lower the outboard end of
drum.

4. After adjustment is made, re-tighten bearing
bolt knobs and check dr um ali gnm ent.

The drum adj ustment lever i s useful when sanding
boards wider t han the drum (see F igure 24). Here
the drum alignm ent is critical and must be adjusted
to exactly lev el to slighly high on the outboard end.
Test alignment with scrap wood approximately 6”
wide by 24” to 40” l ong. Run board t hrough sander
sideways so that end of board extends beyond e nd
of drum. Rotate board 180° and sand the other
end. If a ridge is visible due to the drum overlap,
then raise outboard end of drum and test again
until ridge is elim inated.

Conveyor Belt Tension and Tracking

Tension and track ing adjustments may oc c asi onally
be necessary duri ng break-i n and n orm al operati on
to compensate for belt stretching.

Tension – To adjust the tension of the conveyor
belt, first adj ust the take-up screw nut (Fi gure 25)
using the attac hed wrench. Do this on both si des of
the conveyor to obtain approxim ately equal tensi on
on both sides of the belt when taut . Insuffici ent belt
tension will cause slippage of conveyor belt on the
drive roll er during sanding operati on; the conveyor
belt is too loose if it can be stopped by hand
pressure appli ed direc tly to the top of the conv eyor
belt. Excessive belt tension can result in bent
roller s, bent brackets, and/or premature wearing of
the bushings or belt.

Tracking – Belt tracking adjustments are made
while the convey or belt is running. After the proper
belt tension is obtained (see above), turn the
conveyor on and set it at the f astest speed sett ing.
Watch for a tendenc y of the conv eyor belt t o drift t o
one side of the convey or . T o adjust trac k ing, tight-

the belt is drif ting, and loosen the take-up screw nut
on the opposite side an equal amount.

Adjusting t he take-up screw nuts on either si de of
the conveyor all ows belt t racki ng adjust m ents to be
made without affecting belt tension.

Note: Adjust t ake-up screw nuts onl y 1/4 turn at a
time. Then allow time for the belt to react to the
adjustment s bef ore proceedi ng f urther. Tr y to av oid
over adjustment s.

Trackers

The sander comes equipped with “Trackers”,
ceramic guides that reduce the amount of
adjustments needed to keep the conveyor belt
tracked (centered) on the conveyor bed (see
Figure 26). These guides have a magnetic backing
to keep them i n place. If a Tracker wears through, it
can be reversed by t urning it over. The Tracker Kit
section on page 27 contains more information
about re-setting trackers.

Conveyor Belt Replacement

1. To replace a worn conveyor belt, lower
conveyor t able to its lowest po sition using the
height adjust ment handle. Unplug the m achine
from the wall rec eptacle, and unplug the mot or
cord from the cont r ol box receptacle.

2. Loosen the conveyor take-up screw nuts (see
Figure 25) to reliev e belt tension, and slide the
driven roller fully inward.

3. Remove the f our bolts that att ach the conveyor
table to t he tabl e mounti ng brack ets. Lif t up t he
conveyor table and remove it from machine.
Avoid teari ng the belt on any edges underneath
the conveyor bed.

4. Install new belt, and re-install conveyor table.
Take care not to damage the Trackers. Tension
and track new belt.

Note: If the c onveyor belt continually tr acks to one

side of the machine, reversing the belt on the
conveyor bed m ay remedy the problem. To make
sure the conv eyor bed is not t wisted, plac e a level
on the conveyor bed. If it is twisted, see page 11 for
instructions on leveling the machine.

If there is still a problem, proceed with the steps
below:

Step 1: Check the conveyor drive roller and the
driven roller to make sure they are parallel to the
surface of t he conveyor bed. T o do thi s, fi r st center
the conveyor belt on the bed. Then lay a straight­edge on the ex posed edge of the conv eyor bed on
the left (outboard) si de, ext ending it ov er the r oller.
See Figure 27. Note the distance between the roller
and the straight edge.

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

Tension Roller Adjustment

on the leading edge of the board, adjust the
outfeed tension r oller. If a sni pe mark occurs on the
trailing end of t he board, adjust the infeed tension
roller.

Tension roll er pr essure can be decrea sed i n one of
two ways:

Method 1

28). Do not disengage screws entirely.
Method 2 -- Raise height of tension rollers as

follows. Repeat Initial Drum Alignment procedure
(page 18), using the drum alignment templates
under the drum , except place a few sheets of paper
under the tensi on roller(s) needing adj ustment. Do
NOT place the paper under t he drum or alignment
templates. Tighten bolts. Repeat this procedure
until the snipe is eliminated.

– Loosen spring retai ning screws (Fi gure

Snipe marks result from too much tension roller
pressure and are identif ied as a visibl e line running
across the width of the board appr oximately 2-1/4”

Improperly adjusted tension

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

Adjusting Table Supports

1. If the conveyor table does not rise and lower
easily, measure the distance between the top
of the base column support and the bottom of
the table suppor t on both the inboard and the
outboard side of the machine. See Fi gures 29
and 30.

2. Compare t hese measurem ents; they should be
within 1/16”. If they are not, disengage the
miter gear on the inboard side of the transfer
rod (Figure 29) by pr ying off the protective cap
with a screwdriv er and looseni ng the set-scr ew
in the gear’s collar.

3. Adjust the conveyor table height using the
height adjustment handle to get the same
measurement on both sides. Then re-engage
the miter gear on the transfer rod, tighten the
set-screw, and replac e the protective cap.

If the conv ey or table is still difficult to raise or lower,
the table support s may need to be r e-centered on
the columns. To do this, loosen the four 3/8”x1” hex
head bolts in e ach tabl e support that connect s it t o
the table m ounting brac kets, adjust a nd ti ghten the
set-screws (Figure 3) to hold the table support in
position. Then tighten the hex head bolts and re­loosen the set-screws. Re-align drum (see
page 18).

Figure 29

Replacing V- Belt

1. Unplug machine from power source.

2. Remove the outer half of belt guard by
removing the six #10-32 screws with a 5/16”
wrench. Sli de the belt guard away from the v­belt. See Figur e 31.

3. Use a flat blade screwdriver to pry off the
protectiv e cap over the inboard mit er gear, and
loosen the set-screw in the gear’s collar.
Remove the miter gear and loosen outboard
collar (Figure 32). Slide cross bar toward
outboard side as shown.

4. Loosen v-bel t tension by loosening pinch bolt in
motor support (Figure 32) and raise motor.
Remove v-belt from pulleys.

5. Install new v-belt and tension the belt by using
the weight of the motor only. Make sure the
pulleys are aligned. Replace transfer rod and
miter gear; ti ghten set-screw on mit er gear and
replace protective cap. Tighten collar on
transfer r od.

6. Install the outer half of the belt guard and
tighten the six screws.

Rotating Drum Bearings

Bearings should be replaced when they allow
excessiv e play of the drum, make excessive noi se
or otherwise indi c ate failure.

If clicking noises in the bearings are a problem,
rotating m ay be a solution instead of replacement,
as follows:

1. Unplug sander fr om power source.

2. Loosen the set-screws in the bearing collar
(Figure 33). Leav e the set-screw wrench i n one
of the set- screws. Then rotate the dr um within
the bearing and ti ghten the set-screws.

3. If the clicking persists, or if the drum shaft is
tight in the bearing and cannot rotate, then
loosen the bearing bolts. Repeat step 2. After
the drum is rotated within the bearing, tighten
the bearing bolts fi r st and then the set-screws.

4. After the machine has run for about 30
minutes, stop t o check that the set-screws and
bearing bolt s are still tight.

Note: It may be necessary to re-align the tension

rollers after rotating the drum bearings. See

Conveyor Belt T ens ion and Trac k ing on page 19.

Figure 32

Replacing Drum Bearings

If the bearings are squealing or are loose, they may
need replacing.

1. Unplug sander fr om power source and remov e
dust cover.

2. Raise conveyor table until the sanding drum
rests on the conveyor .

3. Outboard: Remove the two knobs and washer s
that are holding the bearing in place. Loosen
the two set-screws in the bearing collar and
slide the bearing off the end of the drum
(Figure 34).

4. Install a new beari ng on the shaft of the drum
and tighten t he bolts. Ti ghten the set-scr ews in
the bearing collar. Make sure the bolts go
through the drum shield and tension roller
support brackets (see exploded view, page 37).

5. Inboard: Remove outer half of belt guard by
removing the six #10-32 screws in the guard.
Slide the belt guard away from the v-belt.

6. Release v- belt tension by loosening pinch bolt
in motor support and raising motor.

7. Loosen the set-screw in the driven pulley and
remove the pulley f r om the shaft.

8. Remove the bolts holding the inboard (right)
bearing in plac e (Figure 35). Slide the inner half
of the upper belt guard off the end of the shaft
along with the beari ng.

9. Instal l the new bearing on the shaft and install
the inner half of the upper belt guard in the
same manner as it was removed. Make sure

Figure 33

the bolts go thr ough the tension roller brack ets
and drum shield. Install the new inboard
bearing.

10. Center the drum between the carriage legs
before tight ening bolts. Tight en the bolts i n the
bearing and the set-screws in the bearing
collar.

11. Install the driven pulley (shown in Figure 35)
making sure it aligns with the drive pulley on
the motor. Tighten the set-screw.

12. Install the outer half of the belt guard cover and
tighten the six #10- 32 screws.

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 dust collection
system is connect ed.

Do not start drum while in

contact with stock!

For sanding with gri ts coarser than 80, you can
raise the conveyor table slightly.

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

Basic Operating Procedure

1. Set depth of cut.

2. Start dust collec tion system.

3. Start drum.

4. Start conv ey or and select feed rate.

5. Feed stock through m ac hine.

To feed stoc k through the 22- 44 Pro-3, rest and
hold the board to be sanded on the conveyor
belt, allowing the conveyor belt to carry the
board into the dr um. Once t he stock is half way
through, reposition yourself to the outfeed side
of the mac hine to receive and c ontrol the board
as it exits.

Setting Depth o f Cut

Adjusting the drum sander for the proper contact
between the abrasiv e and the stock determ ines
the mechanic al depth of cut.

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:

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.

Selecting SandSmart™ Feed Rates

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

Begin experimenting with the feed rate set at
about 40% to 50% of maximum. T he best feed
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 directly 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 overworking, 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.

Establishing Proper Drum Height

The depth of cut i s controll ed by t he table hei ght
adjustment handle which raises or lowers the
conveyor table under the drum.

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 raise conveyor table until
the drum contacts the stock. Drum should still
rotate by hand.

during operation. When the red indicator light
(B, Figure 36) comes on, the SandS mart 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 manual.

Tips for Maximum Performance

The versatility designed into the 22-44 Pro-3
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 sander 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 machi ne
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 smaller than 2-1/2”
diameter shoul d not be used.

Multi pl e- Piece Sandin g Ru ns

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 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 that when using
abrasives finer than 80 grit the drum is in contact
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 eff ort, 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 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°
(see Figure 37).

25

Angling the workpiece for stock removal
provides other advantages, such a s less loadi ng
of certain areas of the drums due to gl ue 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 final one or
two passes.

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 comply may
cause serious inj ury.

Keeping the Machine Clean

For best results, make cleani ng 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.

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

• Lubricate conveyor bushings and check for
wear.

• Lubricate all m oving part s, such as threaded
rods, washers, and col umn t ubes. (Beari ngs
are pre-sealed and requi r e no lubrication.)

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

• 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 table supports, bearings, conv eyor
coupler, c astings, pulleys and miter gears.

Tracker Kit

Stock No.: 98-0080
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 38.

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 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 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 cov er ed
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 installed properly, only the

bottom lip of t he Tracker will be vi sible. The
top slot i s to be used if the bottom slot wears
out.

8. Install second Tracker opposite the f irst. 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 bolt s and tighten.

Be careful not to knock
Tracker(s) out of conveyor bed when turning
convey or ov e r .

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 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 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.

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 Abrasives

It is important to select the proper grit of
abrasive for the type of sanding bei ng per formed
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
Abrasive Selection Guide (below) shows the
general uses for the various grits. JET offers
abrasives in most of the grits shown – consult
the stock numbers on page 32 to order .

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.

pre-cut lengths or in the convenient

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 1 hour, then u sing a brus h to rem ove
any build-up. Dr y the abrasive strips completel y
before using. Any used solvents should be
discarded in compliance with environmental
regulations.

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.
