Automatic Thermal Overload Protection
This pump motor has a built-in automatic thermal overload
protector. If the motor overheats, the protector wiU open
and cut off power to the motor before the heat damages it
internally. The overload will reset automatically and the

ger point.
_DO NOT attempt to work on the pump or
motor if the overload seems to have tripped. The
motor may restart without warning at any time. You
could be injured and the pump damaged if it starts
when you are working on it.
DO NOT attempt to repair a non-operational sump pump.
Take it to Sears for service by a qualified technician.
