Motor
The motor has a manual 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.
