Motor stalls (resulting in
blown fuses or tripped cir-
cuit).
Machine slows when oper-
ating.
loud, repetitious noise com-
ing from machine.
Machine vibrates exces-
sively.
pOSSIbLE cauSE
1. low voltage.
2. open circuit in motor or loose connec-
tions.
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. Motor overloaded.
2. air circulation through the motor restrict-
ed.
1. short circuit in motor or loose connec-
tions.
2. low voltage.
3. incorrect fuses or circuit breakers in
power line.
4. Motor overloaded.
1. applying too much pressure to
workpiece.
2. undersized circuit or using ext cord.
3. run capacitor is a fault.
1. Main drive roller hex nut is missing or
loose.
2. Motor fan is hitting the cover.
1. stand not stable on floor.
2. loose motor mounting.
3. weak or broken tension spring.
4. idler roller is too loose.
5. Broken/defective sanding belt.
cOrrEctIvE actIOn
1. Check power line for proper voltage.
2. inspect all lead connections on motor for loose or open connec-
tions.
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.
1. reduce load on motor.
2. Clean out motor to provide normal air circulation.
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.
1. sand with less pressure—let the movement of the belt do the
work.
2. Make sure circuit wires are proper gauge & don’t use extension
cords!
3. replace run capacitor.
1. inspect keys and setscrews. replace or tighten if necessary.
2. tighten fan or shim cover.
1. secure stand to floor, reposition to level surface, or shim stand.
2. Check/tighten motor mounting.
3. replace spring.
4. adjust idler roller.
5. replace sanding belt.
troubleshooting Machine
