SYMPTOM
Motor will not start
Motor will not start;
fuses blown or circuit
breakers are tripped
Motor fails to develop
full power (power
output of motor de-
creases rapidly with
decrease in voltage
at motor terminals)
Motor overheats
Motor stalls (result-
ing in blown fuses or
tripped circuit break-
ers)
Machine slows down
while operating
Abrasive belt runs off
top wheel
Dust collection not
working
TROUBLESHOOTING
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
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
Applying too much pressure to work-
piece
Not tracking properly
1. Dust collection bag full
2. Belt loose or broken
3. Impeller loose or broken
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
1. Reduce the load on the power line
2. Increase wire sizes, or reduce length of wiring
3. Request a voltage check from the power com-
pany
Reduce load on motor
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
Ease up on pressure
See operation "Adjusting Belt Tracking"
1. Empty dust collection bag
2. Replace belt
3. Replace impeller
