Troubleshooting
Motor & Machine Operation
symptom possible Cause possible solution
Motor will not start. 1. thermal overload relay inside magnetic
switch has tripped.
2. low voltage.
3. open circuit in motor or loose connections.
4. Emergency stop button depressed.
1. press the rEsEt button on the thermal overload
relay; investigate reason it tripped to prevent future
problems.
2. Check power line for proper voltage.
3. inspect all lead connections on motor for loose or
open connections.
4. rotate clockwise until it pops out/replace.
Fuses or circuit
breakers blow. 1. short circuit in line cord or plug.
1. repair or replace cord or plug for damaged insulation
and shorted wires.
Motor fails to
develop full power
(output of motor
decreases rapidly
with decrease in
voltage at motor
terminals).
1. power line overloaded with lights, appliances,
and other motors.
2. Undersized wires or circuits too long.
3. Motor run capacitor at fault.
1. reduce load on power line.
2. increase wire sizes or reduce length of the circuit.
3. replace run capacitor.
Motor overheats. 1. Motor overloaded during operation.
2. Air circulation through the motor restricted. 1. reduce cutting load; take lighter cuts.
2. Clean out motor to provide normal air circulation.
Motor stalls or shuts
off during a cut. 1. Motor overloaded during operation.
2. thermal overload protection tripped in
magnetic switch.
3. short circuit in motor or loose connections.
4. Circuit breaker tripped.
1. reduce cutting load; take lighter cuts.
2. press the rEsEt button on the thermal overload
relay, located inside the magnetic switch.
3. repair or replace connections on motor for loose or
shorted terminals or worn insulation.
4. install correct circuit breaker; reduce # of machines
running on that circuit.
Cutterhead slows
or squeals when
cutting, especially
on start-up. 1. v-belt loose.
2. v-belt worn out. 1. tighten v-belt ( Page 27).
2. replace v-belt ( Page 27).
loud repetitious
noise coming from
machine.
1. pulley setscrews or keys are missing or
loose.
2. Motor fan is hitting the cover.
3. v-belts are damaged.
1. inspect keys and setscrews. replace or tighten if
necessary.
2. Adjust fan cover mounting position, tighten fan, or
shim fan cover.
3. replace v-belts ( Page 27).
vibration when
running or cutting.
1. loose or damaged blade.
2. damaged v-belt.
3. Worn cutterhead bearings. 1. tighten or replace blade.
2. replace.
3. Check/replace cutterhead bearings.
