Troubleshooting
This section covers the most common problems and corrections with this type of
machine. WARNING! DO NOT make any adjustments until power is disconnected and
moving parts have come to a complete stop!
PROBLEM POSSIBLE CAUSE CORRECTIVE ACTION
Motor will not start. 1. Emergency stop button depressed.
2. Thermal protection circuit.
Breaker amperage is set too low.
3. Open circuit in motor or loose
connections.
4. Start capacitor at fault.
1. Rotate clockwise until it pops out/replace.
2. Unplug machine, open magnetic switch cover,
turn amperage dial on Thermal Protection Circuit
Breaker to a higher amperage setting.
3. Inspect all lead connections on motor for loose or
open connections.
4. Replace start capacitor.
Fuses or circuit breakers
blow. 1. Short circuit in line cord or plug. 1. Repair or replace cord or plug for damaged insula-
tion and shorted wires.
Motor fails to develop full
power (output of motor
decreases rapidly with
decrease in voltage at
motor terminals). 1. Undersized wires or circuits too
long.
2. Motor run capacitor at fault.
1. Increase wire sizes or reduce length of the circuit.
2. Replace run capacitor.
Motor overheats. 1. Motor overloaded during opera-
tion.
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 opera-
tion.
2. Thermal protection circuit.
Breaker amperage is set too low.
3. Short circuit in motor or loose
connections.
4. Circuit breaker tripped.
1 . Reduce cutting load; take lighter cuts.
2. Unplug machine, open magnetic switch cover,
turn amperage dial on Thermal Protection Circuit
Breaker to a higher amperage setting.
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 24).
2. Replace V-belt ( Page 24).
L oud repetitious noise
coming from machine.
1. Pulley setscrews or keys are miss-
ing 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 24).
Vibration when running or
cutting. 1. Loose or damaged knife.
2. Damaged V-belt.
3. Worn cutterhead bearings. 1 . Tighten or replace knife (Page 27).
2. Replace V-belt ( Page 24).
3. Check/replace cutterhead bearings.
