Motor

The motor has an automatic reset thermal overload protector switch. If the motor overheats for any reason, the overload protector will shut off the motor. The motor must be allowed to cool down before resetting the overload switch and restarting.

If the overload protector shuts the motor off frequently, check for a possible voltage problem. Low voltage can also be suspected when:

1.The motor does not get up to full power or speed.

2.Fuses blow out when starting the motor; lights dim and remain dim when motor is started and is running.
