TROUBLE SHOOTING -- MOTOR (Continued)
TROUBLE
Motor starts slowly
or fails to come up
to full speed.
Motor overheats.
Starting relay in motor will not operate.
Motor stalls (resulting in blown fuses or tripped circu it breakers).
Frequent opening of fuses or circuit breakers.
PROBABLE CAUSE
1.Low voltage will not trip relay.
2.Windings burned out
or open.
3.Starting relay not operating.
1.Motor overloaded.
2.Improper cooling. (Air circulation restricted through motor due to sawdust, accumulating inside of saw).
1.Burned relay contacts (due to extended
2.Shorted capacitor (when equipped)
3.Loose or broken connections.
I.Starting relay not operating.
2.Voltage too low to permit motor to reach operating speed.
3.Fuses or circuit breakers do not have sufficient capacity.
1.Motor overloaded.
2.Fuses or circuit breakers do not have sufficient capacity.
3.Starting relay not operating (motor does not reach speed).
REMEDY
1.Request voltage check from the power company.
2.Have motor repaired or replaced.
3.Have relay replaced.
1.Feed work slower into blade.
2.Clean out sawdust to provide normal air
circulation through motor.
See "Maintenance and Lubrication" section.
1.Have relay replaced and request a voltage check from the power company.
2.Test capacitor and replace if defective.
3.Have wiring checked and repaired.
1.Have relay replaced.
2.Request voltage check from the power company.
3.Install proper size fuses or circuit breakers.
1.Feed work slower into blade.
