Palmgren Operating Manual & Parts List
SYMPTOM
Motor will not start
Motor will not start; fuses blown or
circuit breakers tripped
Motor fails to develop full power
(power output of motor decreases
rapidly with decrease in voltage at
motor terminals)
Motor overheats
Motor stalls
(resulting in blown fuses or
tripped circuit breakers)
Machine slows down while operating
Abrasive belt runs off top wheel
TROUBLESHOOTING
POSSIBLE CAUSE(S)
1. Low voltage
2. Open circuit in motor or loose
connections
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. Undersized wires or circuits too long
3. General overloading of power
company's facilities
4. V-belt tension not correct
1. Motor overloaded
2. V-belts tension not correct
1. Short circuit in motor or loose
connections
2. Low voltage
3. Incorrect fuses or circuit breakers in
power line

CORRECTIVE ACTION
1. Check power line for proper voltage
2. Inspect all lead connections on motor for
loose or open connection
1. Insect 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 load on power line
2. Increase wire sizes, or reduce length
of wiring
3. Request a voltage check from power
company
4. Replace V-belt
1. Reduce load on motor.
2. Replace V-belt
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
