PROBLEM CAUSE SOLUTION
Sanding
grains easily
rub off belt
or discs 1) Sanding belt/disc has been stored in an
incorect environment.
2) Sanding belt/disc has been damaged or
folded. 1) Store sanding accessories away from extremely
hot/dry tempuratures.
2) Store sanding accessories flat—not bent or
folded.
Deep sand-
ing grooves
or scars in
workpiece. 1) Sanding belt/disc grit is too coarse for the
desired finish.
2) Workpiece sanded across the grain.
3) Too much sanding force on workpiece.
4) Workpiece held still against belt-disc for
too long. 1) Use a finer-grit sanding 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 accessory.
Sanding
surface clogs
quickly 1) Too much pressure against belt/disc
2) Sanding softwood. 1) Reduce pressure on workpiece while sanding.
2) Use differents stock/sanding accessories, or ac-
cept that this will happen and plan on cleaning or
replacing belts/discs frequently.
Burns on
workpiece 1) Use a sanding grit that is too fine.
2) Using too much pressure.
3) Work held still for too long. 1) Use a coarser-grit sanding accessory.
2) Reduce sanding pressure on workpiece
3) Do not keep workpiece in one place for too
long.
Motor will
not start—
fuses or
circuit break-
ers tripping/
blowing 1) Short circuit in line, cord or plug.
2) Short circuit in motor or loose connec-
tions
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.
3) Install correct fuses or circuit breakers or switch
tool to an appropriately sized circuit.
Motor over-
heats 1) Motor overloaded
2) Extension cord too long with an insuf-
ficient gauge. 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 connec-
tions.
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.
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.
