SYMPTOM PROBABLE CAUSE CORRECTIVE ACTION
Sanding Grains easily
rub off belt or discs. 1. Sanding belt/disc has
been stored in an incorrect
environment.
2. Sanding belt/disc has been
damaged or folded.
1. Ensure sanding
accessories are stored
away from extremely hot
or dry temperatures.
2. Store sanding accessories
Ń=P„JKP>AJPKNBKH@A@
Deep sanding grooves
or scars in workpiece. 1. Sanding belt/disc grit is
too coarse for the desired
łJEOD
2. Workpiece sanded across
the grain.
3. Too much sanding force on
the workpiece.
4. Workpiece held still against
the belt-disc for too long.
1. 2OA=łJANCNEPO=J@EJC
accessory.
2. Sand with the grain of the
wood.
3. Reduce pressure on
workpiece while sanding.
4. Keep workpiece moving
while sanding on the
sanding accessor y.
Sanding surface clogs
quickly. 1. Too much pressure against
belt/disc.
2. Sanding softwood.
1. Reduce pressure on
workpiece while sanding.
2. Use different stock,
different sanding
accessories, or accept tha t
this will happen and plan
on cleaning or replacing
belts/discs frequently.
Burns on workpiece. 1. Using a sanding grit that is
PKKłJA
2. Using too much pressure.
3. Work held still for too long.
1. Use a coarser-grit sanding
accessory.
2. Reduce pressure on
workpiece while sanding.
3. Do not keep workpiece in
one place for too long.
Motor will not start. 1. Low voltage.
2. Open circuit in motor or
loose connections.
3. Blown fuse or breaker.
4. Check power source for
proper voltage.
5. Inspect all lead
connections on motor for
loose or open connections.
(Send for Servicing)
6. Short circuit. (Send for
Servicing.)
7. Improper match between
tool and circuit, fuse or
breake r.

fuses or circuit breakers
tripping or blowing. 1. Short circuit in line, cord or
plug.
2. Short circuit in motor or
loose connections.
3. Incorrect fuses or circuit
breakers in power line.
1. Inspect cord or plug for
damaged insulation and
shorted wires.
2. Inspect all connections on
motor for loose or shorted
terminals and/or worn
insulation.

Motor overheats. 1. Motor overloaded.
2. Extension cord too

gauge (weight).
1. Reduce load on motor
(pressure on object being
sanded).
2. Utilize an extension cord of
appropriate gauge and length
or plug tool directly into outlet.
Motor stalls (resulting in
blown fuses or tripped
circuit). 1. Short circuit in motor
or loose connections.
2. Low voltage.
3. Incorrect fuses or
circuit breakers in
power line.
4. Motor overload.
1. Inspect connections on motor
for loose or shorted terminals
or worn insulations. (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 appropriate circuit,
matched to an appropriate
fuse or breaker.
4. Reduce the load on the motor.
Machine slows when
operating. 1. Feed rate too
great.
2. Undersized
circuit or use
of undersized
extension cord.
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 eliminate use of
extension cords.
Machine vibrates
excessively. 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 accessories.
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.
Workpiece frequently
gets pulled out of
operator’s hands. 1. Not supporting the
workpiece against the
stop.
2. Attempting to sand
(unaided) a workpiece
that is too small.
1. Use the platen (backstop) or
mitre gauge to support the
workpiece.
2. Use another hand tool or jig to
grasp or hold the workpiece.
Workpiece lifts up from
the sanding disc/table. 1. Sanding on the “up”
side of the wheel.
1. Sand on right side of sanding
disc (as operator faces the
disc).
3. Install correct fuses or
circuit breakers or switch
tool to an appropriately
sized circuit.
Motor will not start –
fuses or circuit breakers
tripping or blowing.
