1. Verify unit is connected to power and Start/Stop switch is in the
Start position (see Power on page 13).
2. Verify unit is connected to power. Set the Start/Stop switch to
the Stop position, depress and release the reset switch, then
reset the Start/Stop switch to the Start position (see Power on
page 13).
One cause of overloading trips, which are not electrical in nature,
is too heavy a cut. The solution is to take a lighter cut.
Verify that planer is on a circuit of correct size. If circuit size is
correct, there is probably a loose electrical lead.
If electric motor is suspect, have a qualified electrician test the
motor for function or take the machine to a service center and
have it tested.
Adjust the dust chute, making sure that the key on the dust chute
depresses the micro-switch on machine.
