Figure 3
5.6 Caster lock knobs
Screw the caster lock knobs (E, Figure 2) into the
threaded holes on the side of the cabinet.
Always tighten the caster lock
knobs before operating the sander.
5.7 Dust Collection
Dust collection is mandatory for a safe work
environment and extended abrasive life. The
PM2244 is equipped with a 100mm dust collection
port. Secure a 100mm dust collection hose to the
port with a hose clamp (Figure 4), and connect to a
high volume dust collector (minimum 800 CFM).
Note: Dryer vent hose is not acceptable for this
purpose.
Figure 4 (hose and clamp not included)
5.8 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 abrasives of different
grits are also available; see sect. 10.0.
(TIP: If you are using an after-market abrasive, use
a new Powermatic-supplied abrasive as a template
to quickly cut a new strip. Alternatively, a diagram
is supplied in Figure 20 showing trim
measurements.)
1. Press fastener lever (F, Figure 5) on outboard
(left) end of drum, and insert tapered end of
abrasive through slit in fastener, as shown.
Insert approximately 3-inches of abrasive strip
into fastener. Align tapered edge of abrasive
strip with left edge of drum.
2. Release fastener lever to secure end of strip.
Figure 5
3. Begin wrapping abrasive around drum. The
tapered edge of strip end should follow edge of
drum.
4. Continue to wrap abrasive in spiral fashion by
rotating drum with one hand and guiding strip
with the other. See Figure 6.

9
Successive windings of strip must not have any
overlap. They should be flush with previous
windings or with a slight gap between.
The last winding should have a 1/16 to 1/8 in.
gap, before insertion into inboard fastener (see
Figure 7).
Figure 6
5. Press inboard take-up lever (G, Figure 7) and
insert trailing end of strip as far as it will go. If
necessary, trim tapered end of abrasive strip.
6. 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 7
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 PM2244 Sander is rated at 230-volt power only.
The sander comes with a plug designed for use on a
circuit with a grounded outlet. Before connecting to
power source, be sure switch is in off position.
It is recommended that the sander be connected to
a dedicated 16 amp circuit with circuit breaker or
fuse. If connected to a circuit protected by fuses,
use time delay fuse marked “T”. 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 equipment-
grounding conductor 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 is properly
grounded. Failure to comply may cause serious or
fatal injury.

10
7.0 Adjustments
Disconnect sander from power
source before making adjustments.
7.1 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. With an abrasive strip on the drum, lower
sanding drum to where it touches top of
conveyor belt.
2. At this drum position, the depth scale pointer
should align with zero mark on scale. If it does
not, loosen screw (Figure 9) and raise or lower
pointer to align with zero on scale.
3. Retighten screw.
Note: Depending on desired accuracy, you may
need to repeat this process when installing
different abrasive grits.
This calibration of depth gauge establishes
“absolute” distance from conveyor belt to drum,
while the control panel allows setting of zero point
for relative distance.
Figure 9
7.2 Conveyor belt tension/tracking
Conveyor belt tension adjustment may be
necessary during the break-in period to
compensate for belt stretching.
7.2.1 Tension adjustment
1. Remove left side cover (Figure 10) by removing
two socket head screws with 4mm hex wrench.
Figure 10
2. Adjust take-up screw nuts (Figure 11) with a
17mm wrench. Do this on both sides of
conveyor to obtain approximately equal tension
on both sides of sanding belt.
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.
3. Reinstall left side cover when tensioning is
complete.
Figure 11
7.2.2 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.
1. Make sure proper belt tension has been
achieved (see 7.2.1 Tension adjustment).
2. Turn on conveyor and set to maximum speed.
Watch for a tendency of conveyor belt to drift
to one side of conveyor. If it drifts, tighten or
loosen take-up screw nut on right side of
conveyor (Figure 11).
Note: Adjust take-up screw nut only 1/4 turn at
a time. Then allow time for belt to react to
adjustments before proceeding further.
Try to avoid over adjustments, as this may
affect belt tension. If tension is affected, if may
become necessary to remove left side cover
and use both take-up screw nuts to accomplish
tensioning and tracking.
7.2.3 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
12. These guides have a magnetic backing to keep
them in place. If a Tracker wears through, it can be
