Automatic Thermal Overload Protection
This pump motor has a built-in automatic thermal overload
protector. If the motor overheats, the protector will open
and cut off power to the motor before the heat damages it
internally. The overload will reset automatically and the
pump will restart after the pump cools down below the dan-
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 sewage pump.
Take it to Sears for service by a qualified technician.

MAINTENANCE
Make certain that the pump is unplugged
before attempting to service or remove any compo-
nent.
1. The motor in the unit is sealed in oil. No additional lubri-
cation is necessary.
2.
IMPORTANT:
Disassembly of the motor assembly will
void the warranty. It might also cause internal leakage and
damage to the unit. If repairs are required, return the
pump to the dealer from whom it was purchased.
3. Pump inlet should be kept clean and free of all foreign ob-
jects.
SERVICE/TROUBLESHOOTING
General
Risk of electric shock. When servicing
pump always disconnect power to electrical outlet
and remove pump electric cord from outlet.
1. If pump does not operate:
a. Check for loose plug at electric outlet.
b. Check for blown fuses or tripped circuit breakers at
fuse box/circuit breaker box.
c. Be sure nothing interferes with action of automatic
float switch.
d. If a, b, and c above check OK, plug in a light that you
know works. If it lights, take your pump to Sears for
service. If it doesn’t light, the electrical circuit is faulty;
consult a licensed electrician.
2. Pump starts, but blows fuses/trips circuit breakers:
After disconnecting power to pump, remove it from
sump. Remove the lower volute (see Figure 6, Page 6)
from bottom of the pump and make sure that the impeller
turns freely. Remove any debris obstructing impeller. If
pump still does not operate correctly, return it to your
nearest Sears Service Center for repairs.
3. Pump runs, but does not empty sump:
a. Clean pump intake.
b. Water may be entering sump faster than the pump can
discharge it.
c. Be sure vertical distance from pump discharge outlet
to discharge pipe outlet is 23 feet or less.
d. Be sure discharge pipe is not plugged or frozen.
