Troubleshooting Mechanical and Electrical Problems
Trouble Probable Cause Remedy
Machine will not
start/restart or
repeatedly trips
circuit breaker or
blows fuses.
No incoming power.
Verify unit is connected to power, on-button is
pushed in completely, and stop-button is
disengaged.
Building circuit breaker trips
or fuse blows.
Verify that jointer is on a circuit of correct size.
If circuit size is correct, there is probably a
loose electrical lead. Check amp setting on
motor starter.
Switch or motor failure (how
to distinguish).
If you have access to a voltmeter, you can
separate a switch failure from a motor failure
by first, verifying incoming voltage at
110/220+/-10% and second, checking the
voltage between switch and motor at
110/220+/-10%. If incoming voltage is
incorrect, you have a power supply problem. If
voltage between switch and motor is incorrect,
you have a switch problem. If voltage between
switch and motor is correct, you have a motor
problem.
Motor overheated.
Clean motor of dust or debris to allow proper
air circulation. Allow motor to cool down
before restarting.
Motor failure.
If electric motor is suspect, you have two
options: Have a qualified electrician test the
motor for function or remove the motor and
take it to a qualified electric motor repair shop
and have it tested.
Unit incorrectly wired.
Double check to confirm all electrical
connections are correct. Refer to the Wiring
Diagram section to make any needed
corrections.
On/off switch failure.
If the on/off switch is suspect, you have two
options: Have a qualified electrician test the
switch for function, or purchase a new on/off
switch and establish if that was the problem
on change out.
