Checking and Filling Engine Oil
CAUTION! Your Warranty is VOID if the
engine’s crankcase is not properly
lled with oil before each use. Before
each use, check the oil level. Do not
run the engine with low or no engine
oil. Running the engine with no or
low engine oil WILL permanently
damage the engine.

Wipe off dipstick area, remove dip-1.
stick and wipe it off with a clean rag.
Reinsert the dipstick (do not thread 2.
in) and remove it to check the oil
level. The oil level should be between the high and low marks on the
dipstick.
Fill the Fuel Tank to about 1 inch un-5.
der the ll neck of the gasoline tank
with the stabilized unleaded gasoline
mixture.
Then replace the Fuel Tank Cap.6.
Start Procedure
If the oil level is below the low mark 3.
add the appropriate type of oil until
the oil level is between the high and
the low marks.
Oil type:
32° F or above = SAE 10W30
Below 32° F = SAE 5W30
Replace the Oil Dipstick.1.
CAUTION! Do not run the engine with too
little or too much oil. The engine will
be permanently damaged.
Checking and Filling Fuel
WARNING! TO PREVENT
SERIOUS INJURY FROM
FIRE:
Fill the fuel tank in a well-venti-
lated area away from ignition sources. Do not smoke.
Before starting the engine:
Follow the Set Up Instruc-a.
tions to prepare the equipment.
Inspect the equipment and b.
engine.
Fill the engine with the prop-c.
er amount and type of fuel
and oil.
Read the Equipment Opera-d.
tion section that follows.
Turn the engine fuel valve to its 1.
“OPEN” position.
Turn the engine power switch to its 2.
ON or RUN position.
Then, turn the engine choke lever to 3.
its “CHOKE” position. Set the choke
lever in the “RUN” position when
starting a warm engine.
Check the fuel level before starting 1.
engine.
To ll the Fuel Tank, rst wipe off the 2.
Fuel Tank Cap and the surrounding
area.
Unscrew, and remove the Fuel Tank 3.
Cap.
Mix fuel stabilizer (not included) with 4.

Grasp the starter handle, and pull 4.
slowly until resistance is felt. While
holding the handle, allow the starter
rope to rewind slowly. Then, pull the
starter handle with a rapid, full arm
stroke. Once again while holding
the handle, allow the rope to rewind
slowly. Repeat as necessary, until
the engine starts.
After the engine starts and warms 5.
up, slowly move the choke lever to its
“RUN” position.

IMPORTANT: Allow the engine to run 6.
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.
Prime the pump. To do this, remove 6.
Access Plug (14) from top of Pump
Housing (10). Fill the pump with clean
water, then replace the Priming Plug.
CAUTION: Never operate the pump
dry, damage may result.
Under normal operating conditions
subsequent maintenance follows the
schedule explained in the MAINTENANCE AND SERVICING section.
Pump Operation
Attach exible input and output hoses 1.
(not included) to the Inlet and Outlet
Pipes (12). Secure them with clamps,
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.
engine and disconnect its spark plug
wire after use. Wait for the engine to
cool, clean external parts with clean
cloth, then store the equipment out
of children’s reach according to the
Storage instructions in this manual.

occurs, have the problem
corrected before further use.
Maintenance Procedures
Many maintenance procedures,
including those not detailed
in this manual, will need to
be performed by a qualied
technician for safety. If you
have any doubts about your
ability to safely service the
equipment or engine, have a
qualied technician service the

Cleaning:4.
For “paper” lter elements: a.
To prevent injury from dust and
debris, wear ANSI-approved safety
goggles, NIOSH-approved dust
mask/respirator, and heavy-duty
work gloves. In a well-ventilated
area away from bystanders, use
pressurized air to blow dust out
of the air lter from the side opposite the lter’s normal air ow (the
“clean” side of the lter).
If this does not get the lter reason-
ably clean, replace it.
For foam lter elements: b.
Wash the element in warm water
Spark Plug Maintenance
Disconnect spark plug wire from 1.
end of plug. Clean out debris from
around spark plug.
Using a spark plug wrench, remove 2.
the spark plug.
Inspect the spark plug: 3.
If the electrode is oily, clean it using a
clean, dry rag.
If the electrode has deposits on it,
polish it using emery paper.
If the white insulator is cracked or
chipped, the spark plug needs to be
replaced.
When installing a new spark plug, ad-4.

Cleaning, Maintenance, and
Lubrication Schedule
Note: This maintenance schedule is
intended solely as a general guide.
If performance decreases or if equipment operates unusually, check systems immediately. The maintenance
needs of each piece of equipment will
differ depending on factors such as
duty cycle, temperature, air quality,
fuel quality, and other factors.
Note: These procedures are in addition to
the regular checks and maintenance
explained as part of the regular operation of the engine and equipment.
After Initial 20 Operation Hour Period:
Change engine oil.a.
Place a suitable container under the 5.
fuel lter.
Disconnect the fuel lines leading to 6.
and from the fuel lter and allow fuel
to drain onto the container.
Install new fuel lter in the same 7.
orientation. Make sure to properly
secure both fuel lines.
Clean up and properly dispose of all 8.
fuel.
Wait for at least one hour before use 9.
to allow all residual fuel vapors to
dissipate. To prevent FIRE, do not
start the engine while the smell of
fuel hangs in the air. Remember to
open the fuel valve before restarting
the engine. It may take a little longer
than usual to start the engine be-
cause the fuel needs to rell the fuel
line and new lter.
Every 25 Operation Hours Thereafter:
Clean/replace air lter element.a.
Inspect/clean spark plug.b.
Every 50 Operation Hours:
Change engine oil.a.
Replace fuel lter (if equipped).b.
Every 100 Operation Hours:
Replace spark plug.a.
Replace air lter element.b.
Note: All maintenance procedures sched-
uled for 25, 50, and 100 operation
