Troubleshooting
Service on these tools should only be performed by an authorized, qualified technician.
SYMPTOM
PROBABLE CAUSE CORRECTIVE ACTION
Motor will not start. 1. Low Voltage.
2. Open circuit in motor or loose
connections.
3. Blown fuse or breaker.
1. Check power source for proper
voltage.
2. Inspect all lead connection on
motor for loose or open
connections. (Send for
Servicing.)
3. Short circuit. (Send for
Servicing.)
4. Improper match between tool
and circuit, fuse or breaker.
Motor will not start
–
fuses
or circuit breakers tripping
or blowing.
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. Inspect cord or plug for
damaged insulation and shorted
wires.
2. Inspect all connections on motor
for loose or shorted terminals
and/or worn insulation.
3. Install correct fuses or circuit
breakers or switch tool to an
appropriately sized circuit.
Motor overheats. 1. Motor overloaded.
2. Extension cord too long and of
insufficient gauge (weight).
1. Reduce load on motor.
2. Utilize an extension cord of
appropriate gauge and length
or plug tool directly into outlet.
Motor stalls (resulting in
blown fuses or tripped
circuit).
1. Short circuit in motor or loose
connections.
2. Low voltage.
3. Incorrect fuses or circuit
breakers in power line.
4. Motor overload.
1. Inspect connections on motor
for loose or shorted terminals or
worn insulation. (Send for
Servicing.)
2. Correct low voltage conditions
(for example: improper
extension cord length and/or
gauge).
3. Install correct fuses or circuit
breakers or plug tool into an
appropriate circuit, matched to
an appropriate fuse or breaker.
4. Reduce the load on the motor.
Machine slows when
operating.
1. Feed rate too great. 1. Reduce the rate at which the
workpiece is fed into the
working area of the tool
(grinding wheel).
