OPERATION
Risk of burns or death from electric shock.
Do not handle pump or pump motor with wet hands or
when standing on wet or damp surface, or in water.
Disconnect power from pump before handling, servic-
ing, or attempting to repair pump.
1. The pump must be standing in at least 1/2” (12.7mm) of
water before starting it (one inch (25.4 mm) is better).
The shaft seal is water lubricated and may be damaged if
pump runs dry.
2. After starting, the pump will lower the water level to
3/16” (4.75 mm) before losing suction. It will not pick up
water less than 3/16” deep when running and will not
operate successfully if started in only 3/16” of water.
3. Do not leave pump unattended! If the pump has been
operating satisfactorily and the discharge stream sudden-
ly stops coming out of the hose, stop the pump immedi-
ately; do not allow it to run dry. A mop or squeegee will
be needed to remove remaining water.
4. The motor is equipped with an automatically resetting
thermal overload protector. If the motor gets too hot, the
overload protector will stop the motor before it is dam-
aged. When the motor has cooled sufficiently, the over-
load protector will reset itself and the motor will restart.
NOTICE:
If the overload protector stops the pump repeat-
edly, disconnect the power from the pump and check it to
find the problem. Low voltage, long extension cords,
clogged impeller, too much back pressure in the dis-
charge hose (as when pumping through 50’ (15 M) of
coiled hose), or running pump with no load, can all cause
excessive cycling and overheating.
AIRLOCKS
When a pump airlocks, it runs but does not move any water.
An airlock will cause the pump to overheat and fail. This
pump has an anti-airlock hole in the bottom of the pump
body. If you suspect an airlock, unplug the pump, clean out
the anti-airlock hole with a paper clip or piece of wire, and
restart the pump.
IMPORTANT:
This hole allows the pump to start priming
within 15 seconds in as little as 1/2” of water. NEVER restart
pump in less than 1/2” of water. Leakage from the anti-air-
lock hole is normal.

TROUBLESHOOTING
SYMPTOM
POSSIBLE CAUSE(S)
CORRECTIVE ACTION
Pump won’t
Blown fuse
If blown, replace with fuse of proper size
start or run
Low line voltage
If voltage under recommended minimum, check size of wiring
from main switch on property. If OK, contact power company.
Defective motor
Replace pump
Impeller
If impeller won’t turn, remove screen. Locate source of binding
Pump operates but
Low line voltage
Use only 14 gauge or larger extension cords. Use short extension cords
delivers little or
when necessary
no water
Something caught in impeller
Clean out impeller
Small diameter garden hose
Use larger diameter garden hose or 1” flexible pipe. Eliminate any
or long discharge line
excess hose. Short hoses work best
Check valve installed without
Drill a 1/16" - 1/8" (1.6 - 3.2 mm) dia. hole between pump
vent hole
discharge & check valve
Air lock
Turn off pump for a few seconds, clean out anti-airlock hole and restart pump
Coils or bends in hose
Straighten hose
