OPERATION
PUMP PRECAUTIONS
Before operating the pump for the first time, please review
IMPORTANT SAFETY INFORMATION (page 2) and BEFORE
OPERATION (page 3).
For your safety, avoid starting or operating the engine in an enclosed
area, such as a garage. Your engine’s exhaust contains poisonous
carbon monoxide gas, which can collect rapidly in an enclosed area
and cause illness or death.
Suction Hose Connection
Use a commercially available hose, hose connector, and hose
clamps. The suction hose must be reinforced with a non collapsible
wall or wire braided construction to prevent suction hose collapse.
Keep the pump as close to the liquid to be pumped as possible. Avoid
bends and sharp turns. Pump performance is best when the pump is
not far above the liquid level and the hose is kept straight.
Self-priming time is also proportional to the suction hose length. Using
a longer suction hose will increase the self-priming time.
Tighten the hose
connector to the
suction hose with a
hose clamp to
prevent air leakage
and loss of suction.
Verify that the
connector sealing
washer is installed
and in good
condition. A loosely
connected suction
hose will reduce
pump performance
and self-priming
ability.
The strainer provided with the pump should always be attached to the
end of the suction hose with a hose clamp as shown.
The strainer will prevent debris from entering the pump that can cause
clogging or damage to the impeller and other parts of the pump.
Discharge Hose Connection
Use a commercially available hose, hose connector, and hose clamp.
A short, large diameter hose will provide lower fluid friction and
improve pump efficiency. A long or small diameter hose increases
fluid friction and reduces pump output.
Tighten the hose clamp to prevent the hose from disconnecting under
high pressure.
Pump Priming
Remove the priming filler cap and completely fill the pump chamber
with liquid before starting the engine. Replace the priming filler cap.
NOTICE
Operating the pump dry will destroy the pump seal.
• Ensure the pump chamber is full of liquid and the suction hose
strainer is submerged in the liquid to be pumped.
• If the unit has been operated dry, stop the engine immediately and
allow the pump to cool before adding priming liquid.
LIQUID RECOMMENDATIONS
The following is a list of chemicals that the multipurpose pump is
capable of pumping. The operator must verify that the liquid that is to
be pumped is on these lists. After each use, drain the pump chamber
into a suitable container and flush with fresh water.
