at no load until warm (1-5 minutes)
with no load after each start-up to allow the engine to stabilize.
Break-in Period
Breaking-in the engine will help to 1.
ensure proper equipment and engine
operation, and will extend the engine’s lifespan. The warranty is void
if the engine is not broken in properly.
The rst 20 hours of operation is the
break-in period.
During the rst 3 hours of use:2.
Do not apply a heavy load to the •
equipment.
Do not operate the engine at its •
maximum speed.
After the rst 20 hours of use:3.
Change the engine oil.•
Locate the pump as close to the wa-3.
ter as possible. The pump should be
on a rm, level surface.
Position the input and output hoses 4.
as required. Place the input hose in
the water to be removed, and output
hose in an appropriate location to
drain the water. Avoid sharp bends or
kinks in the hoses.
Check that the pump is not jammed. 5.
Disconnect the spark plug wire on the
engine, then slowly pull the Starter
Handle to rotate the engine and
pump. If the pump does not rotate
freely, clear it before proceeding.

as the seal must be air and water
tight. Attach the included accessory
Basket Filter (18 and 19) to the input
end of your exible input hose.
CAUTION:2. Do not operate the pump
without a basket lter on the input
hose. This prevents large objects
from being sucked into the Pump
and/or damaging the Pump.
Start the engine. The pump will start 7.
to operate as soon as the air is removed from the input hose.
STOP THE PUMP AS SOON AS 8.
WATER IS REMOVED. DO NOT
ALLOW PUMP TO RUN DRY, DAMAGE TO THE PUMP WILL RESULT.
Whenever possible, operate the 9.
pump for 2-3 minutes with clear water
after pumping dirty water to clear it.
Drain the water from the pump and 10.
disconnect the exible hoses.
To prevent accidents, turn off the 11.

shorten Engine life. See Specications on page 6 for recommended oil
type.
