1. rotate clockwise until it pops out/replace.
2. repair or replace cord or plug for damaged insulation
and shorted wires.
3. replace start capacitor.
4. unplug machine, open magnetic switch cover, turn
amperage dial on thermal protection Circuit Breaker
to a higher amperage setting. if dial cannot be set any
higher, replace motor.
5. inspect all lead connections on motor for loose or
open connections.
1. replace run capacitor.
2. reduce cutting load; take lighter cuts.
3. Clean out motor to provide normal air circulation.
4. reduce cutting load; take lighter cuts.
5. unplug machine, open magnetic switch cover, turn
amperage dial on thermal protection Circuit Breaker
to a higher amperage setting. if dial cannot be set any
higher, replace motor.
6. repair or replace connections on motor for loose or
shorted terminals or worn insulation.
7. install correct circuit breaker; reduce number of
machines running on that circuit.
1. tension v-belt (page 48).
2. replace v-belt (page 48).
1. inspect keys and set screws. replace or tighten if
necessary.
2. replace v-belts (page 48).
3. adjust fan cover mounting position, tighten fan, or
shim fan cover.
