SYMPTOM
Motor stalls (resulting in
blown fuses or tripped
circuit).
Machine slows when oper-
ating.
Machine vibrates exces-
sively.
Workpiece frequently gets
pulled out of operator's
hands.
Workpiece lifts up from the
sanding disc/table.
PROBABLE CAUSE
1. Short circuit in motor or loose
connections.
2. Low voltage.
3. Incorrect fuses or circuit break-
ers in power line.
4. Motor overload.
1. Feed rate too great.
2. Undersized circuit or use
of undersized extension
cord.
1. Incorrect motor mounting.
2. Incorrect sanding-belt tension.
3. Weak or broken tension spring.
4. Idler roller is too loose.
5. Broken/defective sanding ac-
cessories.
1. Not supporting the workpiece
against the stop.
2. Attempting to sand (unaided) a
workpiece that is too small.

CORRECTIVE ACTION
1. Inspect connections on motor
for loose or shorted terminals
or worn insulation. (Send for
Servicing.)
2. Correct low voltage conditions
(for example: improper extension
cord length and/or gauge).
3. Install CORRECT fuses or circuit
breakers or plug tool into an ap-
propriate circuit, matched to an
appropriate fuse or breaker.
4. Reduce the load on the motor.
1. Reduce the rate at which the
workpiece is fed into the working
area of the tool.
2. Ensure circuit wires or extension
cords are proper gauge, or elimi-
nate use of extension cords.
1. Have motor mountings inspected
by service technician.
2. Adjust tension-adjustment knob.
Follow belt tensioning/tracking
instructions in this manual.
3. Have tension spring replaced by
service technician.
4. Have service technician adjust
idler roller.
5. Replace sanding belt/disc.
1. Use the platen (backstop) or
mitre gauge to support the work-
piece.
2. Use another hand tool or jig to
grasp or hold the workpiece.
1. Sand on right side of sanding
disc (as operator faces the disc).
