Palmgren Operating Manual & Parts List 9683295
Motor will not start; fuses or circuit
breakers blow
1. Short circuit in line cord or plug
2. Short circuit in motor or loose
connection
3. Incorrect fuses or circuit breakers in
power line
4. Motor overloaded
5. Bandwheel door covers are open
1. Inspect line cord or plug for damaged
insulation and shorted wires. Replace
damaged wires and/or components.
2. Inspect all lead terminals on motor for loose
or worn insulation on wires. Tighten any
loose connections. Replace or repair motor.
3. Install correct fuses or circuit breakers
4. Reduce load on motor
5. The bandwheel doors must be completely
closed and latched
Motor fails to develop full power (power
output of motor decreases rapidly) with
decreased voltage at motor terminals
1. Power Line overloaded
2. Undersized wires or cords too long
3. General overloading at power
company’s facilities
1. Reduce the load on the power line
2. Increase the wire sizes or reduce the length
of cords
3. Request a voltage check from the power
company
Motor overheats
1. Motor overloaded
1. Reduce load on motor
2. Air circulation around motor is
restricted
2. Clean motor to provide normal air circulation
around motor
Motor stalls (resulting in blown fuses or
tripped circuit breakers)
1. Short circuit in motor; connections
loose; or shorted terminals; or worn
insulation on lead wires
2. Low voltage line conditions
3. Incorrect fuses or circuit breakers in
power line
4. Motor overloaded
1. Inspect all lead terminals on motor for loose
or worn insulation on wires. Tighten any
loose connections. Replace or repair motor.
2. Correct low voltage line conditions
3. Install correct fuses or circuit breakers
4. Reduce load on motor
Frequent opening of fuses or circuit
breakers
1. Motor overloaded
2. Incorrect fuses or circuit breakers
1. Reduce load on motor
2. Install correct fuses or circuit breakers
Motor problems in general
Various causes
To troubleshoot and service the motor consult a
qualified technician
Motor running too hot
1. Blade tension too high
2. Blade too coarse for work (especially
when cutting pipes)
3. Blade too fine for work (heavier, soft
materials)
4. Gears need lubrication
1. Reduce tension on the blade
2. Change the type of blade. See OPERATION
BLADE SELECTION GUIDELINES page 9.
3. Change the type of blade. See OPERATION
BLADE SELECTION GUIDELINES page 9.
