Troubleshooting - Craftsman 351.225930 Operator's Manual

SYMPTOM
Motor will not start
Motor will not start;
fuses blown or circuit
breakers are tripped
POSSIBLE CAUSE(S)
1. Low voltage
2. Open circuit in motor or loose
connections
3. Defective switch
4. Defective capacitor
1. Short circuit in line cord or plug
CORRECTIVE ACTION
1. Check power line for proper voltage
2. inspect all lead connections on motor for loose or
open connection
3. Replace switch
4. Replace capacitor
1. inspect line cord or plug for damaged insulation and
shorted wires
2. inspect all lead connections on motor for loose or
shorted terminals or worn insulation on wires
3. install correct fuses or circuit breakers
Motor fails to develop full 1. Reduce the load on the power line
power (power output of
motor decreases rapidly 2. increase wire sizes, or reduce length of wiring
with decrease in voltage 3. Request a voltage check from the power company
at motor terminals)
Motor overheats Reduce load on motor
2. Short circuit in motor or loose
connections
3. incorrect fuses or circuit breakers in
power line
1. Power line overloaded with lights,
appliances and other motors
2. Undersize wires or circuits too long
3. General overloading of power
company's facilities
Motor overloaded
1. Short circuit in motor or loose
connections
2. Low voltage
3. incorrect fuses or circuit breakers in
power line
4. Motor overload
Motor stalls (resulting in
blown fuses or tripped
circuit breakers)
1. inspect connections in motor for loose or shorted
terminals or worn insulation on lead wires
2. Correct the low line voltage conditions
3. install correct fuses or circuit breakers
4. Reduce load on motor
Machine slows down Applying too much pressure to workpiece Ease up on pressure
while operating
Abrasive belt runs off top Not tracking properly See operation "Adjusting Belt Tracking"
wheel
Dust collection not 1. Dust collection bag full 1. Empty dust collection bag
working
2. Belt loose or broken 2. Replace belt
3. impeller loose or broken 3. Replace impeller
