Belt Tracking Adjustment
The belt should run at the center of the belt arm
without veering to the left or right. Check this as
follows:
1. Disconnect machine from the power source.
2. Rotate the belt by hand and observe how it
tracks. The belt should run centered on the
belt wheels.
3. If the belt has a tendency to track left or right
of center, loosen locking nuts (A, Figure 28).
4. Turn the front screw (B, Figure 28) while
turning the belt by hand and observe belt
tracking. Once the belt starts to move in the
desired direction, stop and turn the rear screw
(C) in the same manner.
NOTE: These
adjustments are sensitive and should be done
in small increments.
5. Grasp the tensioning adjustment handle (D)
and start the machine. Be ready to pull down
on the tension adjustment handle should the
belt want to run off the belt wheel.
6. Fine adjustment of the tracking may be
necessary. When the tracking has stabilized,
slowly release the belt tensioning arm and let
the machine run for two minutes.
7. Tighten lock nuts (A) when tracking
adjustments are satisfactory.
Belt Replacement
1. Disconnect machine from the power source.
2. Remove the lock knob and open the left side
panel.
3. Release belt tension using the handle (D,
Figure 28), and slide belt off the wheels.
4. Refer to “Installing Abrasives” section for
instructions on installing the new belt.
Abrasive Disc Replacement
1. Disconnect machine from the power source.
2. Slowly work the tip of a knife under the
abrasive disc, and work it around the
circumference of the disc until abrasive can be
removed by hand.
3. Clean the aluminum disc of any residual
adhesive, using mineral spirits or similar
solvent. Allow to dry.
4. See “Installing Abrasives” for instructions on
installing the new abrasive disc.

Maintenance
Before doing maintenance on
the machine, disconnect it from the electrical
supply by pulling out the plug or switching off
the main switch! Failure to comply may cause
serious injury.
Wipe the machine down after each use.
Keep exposed metal surfaces clean and rust-free.
A light coat of paste wax applied to the tables will
help protect the surfaces.
Make periodic inspections of the sander, checking
fastener tightness, abrasive wear, tracking
accuracy, etc. Listen for any unusual motor noises
or vibrations that might indicate bearing fatigue.
(Note: All rotating parts run on sealed ball bearings
and do not require lubrication.)
If you will not be using the machine for an extended
period, remove the abrasive belt; this will prevent it
from stretching and will prolong its life.
If the power cord is worn, cut, or damaged in any
way, have it replaced immediately.
