Operation
will stop the motor before it is damaged. When the motor has cooled
sufficiently, the overload protector will reset itself and the motor will
restart.
NOTICE If the overload protector stops the pump repeatedly,
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 discharge hose (as when pumping through 50' (15 M)
of coiled hose), or running pump with no load, can all cause excessive
cycling and overheating. However, if the motor overload stops the
pump, allow it to cool for one hour before restarting. Motor will not
restart before the overload has cooled.

CORRECTIVE ACTION
If blown, replace with fuse of proper size
If voltage under recommended minimum, check size of wiring
from main switch on property. If OK, contact power company
Replace pump
If impeller won't turn, remove screen. Locate source of binding
Use only 14 gauge or larger extension cords. Use short extension cords
when necessary
Clean out impeller
Use larger diameter garden hose or 1" flexible pipe. Eliminate any
excess hose. Short hoses work best
Drill a 1/16" - 1/8" (1.6 - 3.2 mm) dia. hole between pump
discharge and check valve
Turn off pump for a few seconds, clean out anti-airlock hole and restart pump
Straighten hose
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-airlock hole is normal.
