SYMPTOM
POSSIBLE CAUSE(S)
CORRECTIVE ACTION
Motor will not start
1. Low voltage
2. Short circuit in line cord or plug
3. Short circuit in motor
4. Open circuit or loose connection in
motor
5. Incorrect fuses or circuit breakers
6. Defective switch
7. Defective capacitor
8. Motor overload results in circuit
breaker tripped
1. Check power supply for proper voltage
2. Inspect line cord and plug for faulty insulation or
shorted connection
3. Inspect connection on motor.
4. Inspect connection on motor
5. Replace with correct fuses or circuit breakers
6. Replace switch
7. Replace capacitor
8. Turn the machine off and reset overload protec-
tion.
Motor stalls or fails to
reach full speed
1. Power overload
2. Low voltage from power supply
3. Undersized line cord
4. Motor overload
5. Short circuit or loose connection in
motor
6. Incorrect fuses or circuit breakers
7. Wood chips clogged
1. Reduce workload on the power supply
2. Check power supply for proper voltage
3. Use line cord of adequate size or reduce length
of wiring
4. Reduce load on motor
5. Inspect the connection in motor for loose or
shorted connection
6. Replace with correct fuses or circuit breakers
7. Inspect chip blower assembly and fan belt. Re-
move excessive wood chips
Motor overheats
1. Motor overloaded
2. Excessive dust build-up results in
decreased air circulation
1. Reduce load on motor. Turn off the machine
until motor cools down
2. Remove dust build-up
Frequent tripping of
circuit breaker
1. Motor overload
2. Inadequate capacity of circuit
breaker
3. Circuit overload
4. Blades are dull
1. Reduce load on motor
2. Replace with correct circuit breaker
3. Reduce circuit load
4. Sharpen or replace blades
