problem persists, check amp setting on the motor

starter inside the electrical box.

3. Planer frequently trips. 3. One cause of overload trips which are not

electrical in nature is too heavy of a cut. The

solution is to take a lighter cut. If too deep of a cut is

not the problem, then check the amp setting on the

overload relay. Match the full load amps on the motor

as noted on the motor plate.

If amp setting is correct then there is probably a

loose electrical lead or a failed component. See

items 9 & 10 below.

tightness of each. Look for any signs of electrical

arcing which is a sure indicator of loose connections

or circuit overload.

6. Motor starter failure. 6. Examine motor starter for burned or failed

components. If damage is found, replace motor

starter. If motor starter looks OK but is still

suspect, you have two options: have a qualified

electrician test the motor starter for function, or

purchase a new starter and establish if that was

the problem on changeout.

If you have access to a voltmeter, you can

separate a starter failure from a motor failure by

first, verifying incoming voltage at 220+/-20 and

second, checking the voltage between starter

motor at 220+/-20.

If incoming voltage is incorrect, you have a power

supply problem.
