immediately when connected to power.
NOTICE In order for the pump to run in the proper
direction, the wires must be connected correctly.

Operation
Risk of electric shock. Can shock, burn
or kill. Do not handle a pump or pump motor with wet
hands or when standing on wet or damp surface, or
inwater.
Risk of fire and explosion. Can cause
severe injury, property damage or death. Do not use in
explosive atmospheres. Pump water only with this pump.

1. The shaft seal and impeller depend on water for
lubrication and cooling. Do not operate the pump
unless it is pumping water. The seal will be damaged
if the pump is allowed to run dry. Fill the inlet hose
with water before each use. Do this before starting
the pump.
NOTICE DO NOT run this pump dry. Running this
pump dry will void the warranty.
2. The pump motor requires a fully charged 12V DC
battery for operation.
Risk of electric shock. Can burn or kill.
Before attempting to check why a unit has stopped
operating, disconnect the pump from the battery.
3. Water should be pumping in 1 minute or less. If not,
make sure that all of the suction connections are air
tight. Most priming problems are due to air leaks in
the suction line. Refill the inlet hose and repeat the
process. If your pump does not prime on the second
try, disconnect the pump from the battery and refer
toTroubleshooting.
NOTICE The motor must have air circulation around
itforpropercooling.Thispumpwillliftwater6’;
trying to lift water more than 6’ can cause the motor
to run hot. The motor has a thermal overload which
will stop it if it gets too hot. If the motor stops,
allow it to cool for 30 minutes before trying to start
itagain.
4. Disconnect the pump from the battery before all the
water is completely gone. Do not run pump dry!
Performance
The pump will deliver 350 gallons/1325 liters per hour
with an unrestricted discharge line. If the discharge line
is restricted or raised and the pressure on the pump
outlet port increases, it will pump less water.
NOTICE This pump’s motor has brushes. Inspect the
brushesfrequently;replacethemiftheyareworn.
Maintenance
1. Replace the impeller and cam ring every 250 hours
of use. See Impeller Replacement.
NOTICE Severe or abrasive use can wear out the
cam ring quickly. Grass, mud, sand or pea gravel
can cause abrasive wear. Use the supplied suction
screen. Keep the pump inlet clear.
2. When you have finished pumping, disconnect the
wires from the power source to be sure the unit is
turned off.
