3. Too much sanding force on
work piece.
4. Work piece held still against the
belt/disc.
3. Reduce pressure on work piece while
sanding.
4. Keep work piece moving while sanding on
the belt/disc.
Sanding surface clogs
quickly or burns.
1. Too much pressure against
belt/disc.
2. Sanding softwood.
1. Reduce pressure on work piece while
sanding.
2. Use different stock. Or accept the
characteristics of the stock and plan on
cleaning/replacing belts frequently.
Glazed sanding
surfaces.
1. Sanding wet stock.
2. Sanding stock with high residue.
1. Dry stock properly before sanding.
2. Use different stock. Or accept the
characteristics of the stock and plan on
cleaning/replacing belts/discs frequently.
Motor will not start.
1. Low voltage.
2. Open circuit in motor or loose
connections.
1. Check power supply for proper voltage.
2. Inspect all lead connections on motor for
loose or open connections.
Motor will not start;
fuses or circuit breakers
blow.
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 or worn insulation.
3. Install correct fuses or circuit breakers.
Motor overheats.
1. Motor overloaded.
2. Incorrect usage of machine.
3. Air circulation through the motor
restricted.
1. Reduce load on motor.
2. Reduce the applied load on the machine.
3. Clean out motor to provide normal air
circulation.
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 overloaded.
1. Inspect connections on motor for loose or
shorted terminals or worn insulation.
2 Correct the low voltage conditions.
3. Install correct fuses or circuit breakers.
4. Reduce load on motor.
Burn marks on work
piece.
1. Using too fine of sanding grit.
2. Using too much pressure.
3. Work held still for too long.
1. Use a coarser grit sanding belt/disc.
2. Reduce pressure on work piece while
sanding.
3. Do not keep work piece in one place for too
long.
Machine slows when
operating.
1. Applying too much pressure to
work piece.
2. Undersized circuit or using ext
cord.
1. Sand with less pressure - let the movement
of the belt/disc do the work.
2. Make sure circuit wires are proper gauge &
don’t use ext cords!
Machine vibrates
excessively.
1. Incorrect motor mounting.
2. Incorrect sanding belt tension.
3. Weak or broken tension spring.
1. Check/adjust motor mounting.
2. Make sure tension lever is in tensioning
position. Follow belt tensioning instructions in
this manual.
3. Replace spring.
