Table Support Screws

The set screws on the table support s (Figure 5)
have been tightened at the factory to eliminate
free-play between the table supports and the
columns during shipment. All four set screws

must be loosened and re-adjusted before
operating either the height adjustment
mechanism or the conveyor drive. Proceed

as follows:

Failure to follow the below

procedure may resul t in misalignment of th e
drum and/or conveyor bed, or may damage
the miter gears.

1. Loosen each hex nut with an open-end

wrench, then loosen the set screw with a
hex wrench.

2. Re-tighten the set screw with your fingers

o

until it only li ghtly touches the column tube.

3. Hol d the set screw in positi on with the hex

wrench, and re-ti ghten the hex nut.

Install Handwheel

Mount the handwheel to the top of the height
adjustment screw (Figure 6). Align one of the set
screws with the flat on the height adjustment
screw, and tighten both set screws.

Install the knob to the threaded hole in the
handwheel, and ti ghten the hex nut agai nst the
handwheel.

Install Conveyor Table

1. Lower the table mounting brackets by

rotating the handwheel.

2. Remove conveyor table from packaging,

and place it on the m ount i ng bracket s of the
stand. The gear motor should be on the
right, or inboard side of the sander as
shown in Figure 7.

3. Secure the conveyor bed with four 3/8”x1”

hex head bolts, 3/8” flat washers and 3/8”
flanged lock nuts.

4. Plug the motor cord into the control box

receptacle (Fi gur e 8) .

IMPORTANT: The conveyor belt has been
overtight ened for shipping purpose s. It must be
tensioned proper ly befor e operating the sander!
See page 19.

neck bolts (J) , 1/4” flat washers (K), and 1/ 4”
hex nuts (L). Do not fully tighten yet.

7. The tabl e should be posi tioned ev en with or
slightly bel ow the conveyor belt surface. T o
check position, place a level or str aight edge
near the left side of the conveyor and
extending out over the table, as shown in
Figure 10. Raise t he conveyor table until the
drum holds the straight edge in pl ace, and
adjust the infeed table unt il it i s ev en with or
slightly below the conveyor belt surface.

8. Place the straight edge near the the right
side of the conveyor table and repeat.
Tighten all hex nuts on the infeed table.

9. Mount the outfeed table in the same manner
as described above. (Removal of existing
screws on the rails will not be necessary for
the outfeed side. )

Figure 10

Leveling the Sander

Proper leveling is important for getting the
maximum performance from your sander.
Before making fine adjustments, place the unit
where it will be used in the shop. Then adjust
the four leg glides (see Figure 4) using a
carpenter’s lev el placed on t he conveyor bed i n
both X- and Y-ax i s positi ons. Make sure t he hex
nuts on the leg glides are tightened securely
against the sander legs.

If you are using the optional casters, level the
sander after positioning the machine where it
will be used most often. Place washers on the
casters as needed to shim up the legs. Mar k the
position of the legs on the f loor with tape so the
sander can be returned to the same position.

Dust Collection

Dust collection is mandatory for a safe work
environment and extended abrasive life. The
sander is equipped wit h a 4” dust collecti on port
at the back of the dust c ov er. It is designed t o be
used with standard 4” dust collection hose
connected to a hi gh volume dust c ollec tor wit h a
minimum capaci ty of 600 CF M.

Using a shop v acuum is not recomm ended for
this machi ne, but if used it should be a 16 gallon
or larger canister type shop vacuum. This
requires conv erting t he dust port down to 2-1/ 2”.
An adapter is av ailable from your dealer (stoc k
no. 80-2910) for converting to the 2-1/2” hose.
Do not reduce hose si ze smaller than 2- 1/2”. For
best results, follow recommendations of the dust
collector manufacturer.

11

Installing Abrasives

An 80-grit abrasive strip is already installed on
the drum of your sander. Page 28 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 JET 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.

1. Mark and cut a t aper at one end of the roll
as shown in Figure 11. Because the t apered
end should use al l of the l eft (outboar d) slot
width, its end must be trimmed back three
inches as shown.

TM

Figure 11

Figure 12

2. Squeeze the fastener lever (Figure 12) 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

13). Successiv e windings of the strip should
be flush with previ ous windings without any
overlap.

5. Mark the trailing end of the strip where it
crosses the ri ght (inboard) end of the drum
(Figure 14).

6. Remove the abrasive strip from the drum,
and cut a taper as was done with the
starting edge (see Figure 11). 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.

Figure 13

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

Figure 14

12

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 15)
and insert its hook into the outside hole of
the fastener lever (see Figure 17).

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 16).

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 16) to allow strip to
be pulled into the fastener as needed. If
necessary, trim the outside edge of the
abrasive strip.

Figure 15

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 17).

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.

Always remove TUFTool from machine before
operating.

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 illustr ated in Fi gure 18. The sander
cannot be rewired to voltages other t han fact or y
settings.

A temporary adapter, which looks like the
adapter ill ustrated in Figure 19, m ay be used to
connect this plug to a two-pole receptacle, as
shown in Figure 19, if a properly gr ounded outlet
is not available. The temporary adapter should
only be used until a properly grounded outlet
can be installed by a qualified electrician. This
adapter is not applicable in Canada. The
green colored rigid ear, lug, or tab, extending
from the adapter, must be connected to a
permanent ground s uch as a pr operl y grounded
outlet box, as shown in Fi gur e 19.

Figure 18

Figure 19

14

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.

Adjustments

Switch Lockout

Unauthorized use of the sander can be
prevented by pulling out the key (Figure 21).
Press switch to OFF position before removing
the key. When the k ey is removed, the drum c an
not be started. (Note, however, that the
conveyor belt can still run when the key is
removed).

To replace the key , slide it back into the switch
until it snaps.

Dust Cover

To access the drum, lift the front of the dust
cover using t he handle and pu sh back the f ront
cover all the way to secure it in open position.
The dust port shoul d be on the bac k 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 cover is pulled from the carriage
leg brackets. Reverse this procedure to 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 height and depth of c ut are controlled
by the height adj ustm ent handwheel (see Fi gure

6). Rotating t he handwheel raises or l ower s both
sides of t he table si multaneousl y by transf erri ng
the handwheel rotation through the miter gear
and transfer r od assembly.

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

15

• The set screws in the table supports have
been loosened and readjust ed ( see page 9).

• The sander has been leveled (page 11).

• Moving parts of the height adjustment

mechanism are well lubricated, including
miter gears, columns, and threaded
adjusting screws.

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

1. Further l oosen t he set screws on the front of
the table supports (see Figure 5).

2. Lubricate thoroughly by appl yi ng penetrating
lubricant to the table supports where they
contact the columns, and to all contact
points of adj usting screws and transfer rod
(see Figure 1). Also apply grease to the
miter gears.

3. If the height adjustment still feels stiff, check
for misalignment of adjusting screw
supports and table supports which could
cause binding on t he adjusti ng screws. The
adjusting screw suppor ts can be adjusted by
loosening the set scre ws which secure t hem
to the columns, and rot ating 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 protective caps with a flat
blade screwdriver, and loosening the set
screws on the gears. Check that the gear
mesh is not too tight or too loose, and that
the gear teeth ali gn with the opposing gear.
Note that the c ollars located on t he transfer
rod (see Figure 1, page 7) should be
positioned to control the lateral movement of
the transfer rod to maintain accurate miter
gear alignm 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 (Fi gure 24), and the ret aining
ring under the height adjustment handl e on
the inboard side of the machine. Both
retaining rings should be snug on their
respective bearings.

If there is a space between the retaining r ing
and the bearing, tighten one set screw in
each of the table supports before performing
the following adjustment:

Figure 24

16

6. If one height adjustment screw is loose,
remove the mi ter gear from t he transfer rod
on that side. T urn down the threaded hei ght
adjustment screw rod until 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.

Depth Gauge Calibration

The depth gauge (A, Figure 25) measures the
distance between the conveyor table and the
sanding drum for thickness dimensioning of
boards. To calibr ate the depth gauge:

1. Loosen the locking knob (B) of the lower
depth gauge support (C) and lower i t so that
it rests on top of the table support (E).

2. Raise the conv eyor t able until it touc hes the
sanding drum. Then loosen the l oc k ing knob
(D) of the upper depth gauge support and
position the “ 0” mark of the scale even wit h
the top of the lower depth gauge support.

3. Tighten the upper depth gauge support in
position.

Once calibrat ed, the locking knob ( B, Figure 15)
of the lower depth gauge support can be
loosened, allowing the lower depth gauge
support to ri de on top of the table support. The
depth can then be r ead where the scale ent ers
the lower depth gauge support.

The depth gauge can also be used as a stop
gauge as follows: Position the lower depth
gauge support (C, Fi gure 25) along the scale to
a desired finish thickness. Then tighten the
lower depth gauge support with the locking k nob
to prevent the conveyor table from being r aised
above that point.

Figure 25

Drum Alignment

The sanding drum must be aligned parallel to
the conveyor table for proper machine
operation. The sanding drum has been pre­aligned at the factory and should not require
immediate adjustment, although it is
recommended that you confirm the alignment
before operating the sander. Proceed as foll ows:

First inspect the alignment with a gauge of some
kind. The following procedure uses a steel
straight edge as a gauge. See Figure 26.

1. Unplug sander fr om power source.

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

Figure 26

17

3. Insert the gauge between the drum and
conveyor bed at one end of the drum
(Figure 26). Raise the conveyor bed while
slowly rotati ng drum by hand until the drum
lightly contacts the thickness gauge.

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

Initial Drum Alignment

1. Release v-belt tension from motor by
loosening pinch bolt of motor support
(Figure 27).

2. Loosen two lower #10-32 screws in belt
guard (Figur e 27 shows one of the screws).
Slide motor support up the column and re­tighten pinch bol t.

3. Because the tension roller suspension
assembly (Figure 28) mounts to the drum
bearing bolts which are used to adjust the
drum, it is necessary to align the sanding
drum and tension rollers at the same time.
Loosen outboard beari ng bolt knobs (Fi gure

28) and the inboard bear ing bolts.

Figure 27

4. With all four bearing bolts loosened, note
that the drum will adjust about 1/2” on each
end. Position drum alignment templates
(Figure 28) on the conveyor and below the
drum with one t emplate at eac h end of the
drum.

5. Raise the conv eyor bed so that the drum i s
resting on both templates but leaving the
drum within its range of adjustment. To
check this, you should be able to lift either
end of the drum off the t emplates and, with
light hand pre ssure on the drum , attempt to
slide templat es with a screw driver to make
sure drum is act ually resti ng on the template
and not just in its lowest position.

6. In t his position, the drum shoul d be resting
on the templates and both tension rollers
resting on the conv eyor surface. Re-ti ghten
bearing bolts and restore v-belt tension.
Tighten pinch bolt in motor support and
tighten two lower screws in belt guard
(Figure 27).

Fine-Tuning Drum Alignment

The 22-44 Pro i s equipped with a dr um adjuster
mechanism that allows easy fine tuning or
changing of drum alignment without repeating
the intial dr um ali gnm ent proc edur e.

Figure 28

1. Raise drum adj ustment lever (Figur e 29) so
that it just engages the side of drum
carriage leg.

Figure 29

18

2. Slightly loosen bearing bolt knobs. (An
internal tooth lock washer is placed under
the head of each bearing bolt to prevent
tension roll ers from droppi ng out of posi tion
if knobs are loosened slightly. If tension
rollers do drop, simply raise to a position
equal to that of the i nboard 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 adjustm ent lev er to lower the outboard
end of drum.

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

The drum adjustment lever is useful when
sanding boards wider t han the dr um (see Fi gure

30). Here the drum ali gnm ent is critical and must

be adjusted to ex actly level to slighly high on t he
outboard end. Test alignment with scrap wood
approximately 6” wide by 24” to 40” long. Run
board through sander sideways so that end of
board extends beyond end of drum. Rotate
board 180° and sand t he other end. If a ridge is
visible due to the drum overlap, then raise
outboard end of dr um and test again until ridge
is eliminated.

Conveyor Belt Tension and Tracking

Tension and tracking adjustments may
occasionally be necessary during break-in and
normal operation to compensate for belt
stretching.

Tension. To adjust the tension of t he conveyor
belt, first adjust the take-up screw nut (Figure

31) using the attac hed wrench. Do this 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 during
sanding operation; the conveyor belt is too loose
if it can be stopped by hand pressure applied
directly to the top of the conveyor belt.
Excessive bel t tension c an result in bent roll ers,
bent brackets, and/ or premature wearing of the
bushings or belt .

Tracking. Belt tracking adjustments are made
while the conveyor belt is running. After the
proper belt t ension i s obt ained ( see above), tur n
the conveyor on and set it at the f astest speed
setting. Watch for a tendency of the conveyor
belt to drift to one side of the conveyor. To
adjust track ing, tight en the t ake-up scre w nut on
the side toward which the belt is drifting, and
loosen the take-up screw nut on the opposite
side an equal amount.

NOTE: Adjust t ake-up screw nuts only 1/ 4 turn
at a time. T hen all ow time f or t he belt t o react to
the adjustments before proceeding further. Try
to avoid over adj ustm ents.

Trackers

he 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 32. These guides have a magnetic
backing to keep them in place. If a Tracker
wears through, it can be reversed by turning it
over. Page 27 contai ns more inform ation about
re-setting trackers.

Conveyor Belt Replacement

1. To replace a worn conveyor belt, lower

conveyor table to its lowest position using
the height adjustment handle. Unplug the

achine from the wall receptacle, and
unplug the motor cord from the control box
receptacle.

2. Loosen the conveyor take-up screw nuts
(see Figure 31) to relieve belt tension, and
slide the driven roller fully inward.

3. Remove the four bolts that attach the
conveyor table to the table mounting
brackets. Lift up the conveyor table and
remove it from machine. Avoid tearing the
belt on any edges underneat h the conv eyor
bed.

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

NOTE: If the conv eyor belt continually tracks to
one side of the machine, reversing the belt on
the conveyor bed may remedy the probl em. To
make sure the conveyor bed is not twisted,
place a level on the conveyor bed. If it is twisted,
see page 11 for instructions on leveling the
machine. If there i s still a problem, proceed with
the steps below:

Figure 32

Step 1: Check the conveyor drive roller and t he
driven roll er to make sure they are parallel to the
surface of the conveyor bed. To do this, first
center the conv ey or belt on the be d. Then l ay a
straight-edge on the exposed edge of the
conveyor bed on the left (outboard) side,
extending i t over t he roller. See Figure 33. Not e
the distance between the roller and the
straightedge.

Figure 33

20

Step 2: Now repeat St ep 1 on the right (inboard)
side of conveyor. Compare the measurements
from side to side. If they are not equal, loosen
one of the brac kets that hold the roll er in place.
Tip this bracket until the distance between the
roller and the straight-edge are equal f rom side
to side, then tight en the bracket.

Tension Roller Adjustment

Snipe marks result from too much t ension roller
pressure and are identified as a visible line
running across the width of the board
approxim ately 2-1/4” from t he end of the board.
If a snipe mark occurs on the leading edge of
the board, adjust t he outfeed tension r oller. If a
snipe mark occurs on the trailing end of the
board, adjust the i nfeed tension roller.

Tension roller pressure can be decrea sed i n one
of two ways:

Method 1: Loosen spring retaining screws
(Figure 34). 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 tension roller(s)
needing adjustment. Do NOT place the paper
under the drum or alignment templates. Ti ghten
bolts. Repeat this procedure until the snipe is
eliminated.

Figure 34

Improperly adjusted tension

rollers (i.e. those set too high, rendering
them non-functional) could allow kickback or
slippage of pieces bein g san ded.

Adjusting Table Supports

1. If the convey or table does not ri se and l ower
easily, measure the distance between the
top of the base column support and the
bottom of the table support on both the
inboard and the outboard side of the
machine. See Figur es 35 and 36.

2. Compare these m easurements; they shoul d
be within 1/16”. If they are not, disengage
the miter gear on the inboard side of the
transfer rod (Figure 35) by prying off the
protective cap with a screwdriver and
loosening the set screw in t he gear ’s collar.

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

Figure 35

Figure 36

21

If the conveyor table is still difficult to raise or
lower, the table supports may need to be re­centered on the col umns. To do t his, loosen the
four 3/8”x1” hex head bolts in each table support
that connects it t o the table mounting br ackets,
adjust and tight en the set scre ws (see Figure 5)
to hold the table support in position. Then
tighten the hex head bol ts and re-l oosen the set
screws. Re-align drum (see page 17).

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 f rom the
v-belt. See Figure 37.

3. Use a flat blade screwdriver to pry off the
protective cap over the inboard mi ter gear,
and loosen the set screw in the gear’s
collar. Remove the miter gear and loosen
outboard coll ar (Figure 38). Slide cross bar
toward outboard side as shown.

4. Loosen v-belt tension by loosening pinch
bolt in motor support (Figure 38) and raise
motor. Re move v-bel t fr om 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; tighten set
screw on mit er gear and replace protect ive
cap. Tighten collar on transfer rod.

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

Rotating Drum Bearings

Bearings should be replaced when they allow
excessive play of the drum, make excessive
noise or otherwise indicate failure.

If clicki ng noises in the beari ngs are a problem ,
rotating may be a solution instead of
replacement, as follows:

Figure 37

Figure 38

1. Unplug sander fr om power source.

2. Loosen the set scre ws in the bearing coll ar
(Figure 39). Leav e the set screw wrench in
one of the set screws. Then rot ate the drum
within the bearing and tighten the set
screws.

3. If the cl icki ng persi sts, or if t he drum shaf t is
tight in t he bearing and cannot rotate, t hen
loosen the bearing bolts. Repeat step 2.
After the dr um is rotated wit hin the bearing,
tighten the bearing bolts first and then the
set sc rews.

Figure 39

22

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

NOTE: It may be necessary to re-align the
tension roll ers after rotating the drum bear ings.
See page 18.

Replacing Drum Bearings

If the beari ngs are squealing or ar e loose, they
may need replacing.

1. Unplug sander from power source and
remove dust cov er.

2. Rai se conv ey or tabl e unti l t he sanding drum
rests on the conveyor .

3. Outboard: Remove the two knobs and
washers that are holding the bearing in
place. Loosen the two set screws in the
bearing coll ar and slide the bearing off the
end of the drum (Figure 41) .

4. Install a new bearing on the shaft of the
drum and tighten the bolts. Tighten the set
screws in the beari ng collar. Make sure the
bolts go through the drum shield and
tension roller support brackets (see
exploded view, page 36) .

Figure 40

5. Inboard: Remov e outer half of belt guard by
removing the six #10-32 screws in the
guard. Sli de t he belt guard away f rom t he v­belt.

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

7. Loosen the set screw in the driven pulley
and remove the pull ey fr om the shaft.

8. Rem ove t he bolt s holdi ng t he inboar d (ri ght)
bearing in place. See Figure 40. Slide the
inner half of t he upper belt guard off the end
of the shaft along wit h the bearing.

9. Install 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 the bol ts go through the tension
roller brackets and drum shield. Install the
new inboard bearing.

10. Center the drum between the carriage legs
before tightening bolts. Tighten the bolts in
the bearing and the set screws in the
bearing collar.

11. Instal l the driv en pull ey (shown in Figure 40)
making sure it aligns wit h the drive pulley on
the motor. Tighten the set screw.

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

Operation

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

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.

Basic Operating Procedure

1. Set depth of cut.

2. Start dust collection system.

3. Start drum.

4. Start conveyor and select feed rate.

5. Feed stock through m ac hine.
To feed stock through the 22-44 Pro, 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 the stoc k is halfway
through, reposition yourself to the outfeed side
of the mac hine to receive and c ontrol the board
as it exits.

Setting Depth of Cut

Adjusting the drum sander f or the proper contac t
between the abrasiv e and the stock determ ines
the mechanical depth of cut.

It may take some ex perimentation t o 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.

Establishing Proper Drum Height

The depth of cut is cont roll 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. Without changing drum
height, finish feeding the stock under the
sander.

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.

Selecting Feed Rates

Selecting proper feed rate is an essential step
after fir st adjusting for dept h of cut. The vari able
feed rate c ontroller of the c onveyor belt adjusts
the load on the machine; it can be infinitely
adjusted withi n its specified range for maximum
operating performance. A faster f eed rat e all ows
faster sanding but fewer revol utions of t he drum
per inch of sandi ng. A slower f eed rate prov ides
more revolutions of the dr um 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 f eed
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 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 wit h usi ng a faster feed rate.

Also try a faster 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, using a shallower dept h 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 the
optimum feed rate. If problems occur, first
check and adjust the feed rate, referring to the
“Troubleshooting” sections in this manual.

Tips for Maximum Performance

The versatili t y designed i nto t he 22-44 Pro dr um
sander allows it to be used for a wide v ariety 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.

24

Learning how to use its adjustments and
controls will allow you to fine-tune the machine
for maximum results. The best results come
from experimenting with different abrasive grits
and machine adj ustments to fit the job at hand.
Following i s a list of useful tips which can hel p
you improve performance of your sander.

Dust Collection

When connecti ng dust coll ect ors, remem ber that
straight pi pe will not restrict airflow as much as
flexible tubing. Y’s and elbows will restrict airflow
less than T’s. Also, a hose smaller than 2-1/2”
diameter shoul d not be used.

Multi pl e- Piece Sandi ng Run s

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

Sanding Multiple Pieces At Once

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

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 contac 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 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 42).

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 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 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

Figure 42

Angling the workpiece for stock removal
provides other advantages, such a s les s l oading
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.

25

Maintenance

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

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.

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.

• Lubricate conv eyor bushings and check for
wear.

• Lubricate all movi ng parts, 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 from t he 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 support s, bearings, conv eyor
coupler, casti ngs, pulleys and miter gears.

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 43.

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

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

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

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

5. Lift conveyor table and slide it out of the
sander. Turn conveyor table upside down.
Be careful not to damage t he conveyor 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 installed pr operl y, onl y
the bottom lip of the Trac ker will be visible.
The top slot is to be used if the bottom slot
wears out.

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

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

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

11. Tension the conveyor belt using take-up
screw nuts. If both Trackers are i nstalled, it
is very important to have equal tension on
both sides of the conveyor belt. Tighten 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 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 being perform ed
to achieve maximum results. As with any
sanding operation, first begin sanding with a
coarser grit, depending upon the roughness of
the stock or the am ount of stock to be rem oved.
Then progressiv ely work toward finer grit s. The
chart (Figur e 44) sho ws the general u ses f or t he
various grits. JET offers abrasives in the ten
different 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 ov e
any build-up. Dr y the abrasive strips completely
before using. Any used solvents should be
discarded in compliance with environmental
regulati ons.

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 t he
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.
