STARTUP
Always usethis startup procedureto ensure that the unit
is started safelyand properly.
1. Check oil levels.
Engine: Add SAE30 or low30weight detergent oil as
necessary.
Pump: Add SAE 20 or 30 weight non-detergent oil as
necessary.
NOTE This unitis equipped with a low-oil sensor that
shuts the engineoff if the oil level falls below a certain
level. If the unit stops unexpectedly, check both the oil
and the fuel levels. Check oil
the
level each time the una
is refueled.
2. Check fuel level.
WARNING
DO NOT refuel a hot engine. Refueling a hot
engine could cause a fire.Use only fresh, clean
regular or unleaded gasoline. Close the fuel
shutoff valve during refueling.
If the engineis cold, completely close the engine choke.
Grasp the starter rope, brace one foot
on the pressure
washer chassis and pull rope rapidly and firmly.
Continue holding the rope
as it returns. Pull and return
the rope until the enginestarts. In cool weather, the
choke may haveto be kept closed for10 to 30 seconds
before opening it to keep the engine running.
Otherwise, open the choke as soon as the engine
starts.
ifthe engine is warm, leave the choke open, or just partly

paragraph. When it starts, be sure to open the choke
completely.

CAUTION
On recoil start engines, never let the starter rope
return by itself.It could jam the recoil system.
7. ALWAYS engage the gun's trigger safety latch
whenever you stop spraying, even for a moment,
to
reduce the risk offluid injectionor splashing in the
eyes oron the skinif the gun is bumped or triggered
accidentally.

than 10 minutes. Doing so may cause the
recirculating water to overheat and seriously
damage the pump. Turnoff the pressure washer
if it will not be spraying or cleaning least
at every
10 minutes. If heated inlet water is used, reduce
this time further.
4. Trigger the gun until water sprays from the tip
indicating that the airis purged from the system.
DO NOT run the pump dry, which will quickly
damage the pump. Be sure the water supply
is
fully turned on before starting the pump.
3. Turn on thewater supply.
Never run the unit dry. Costly damage to the pump
5. Open the fuel shutoff valve. Be sure the spark plug
ignition cableis pushed fiirmly onto the spark plug.
On those units equipped with an ignition shutoff
switch, put the switch in the "on" position and put
the throttlein the "run" position.
6. Start the engine.
DO NOT operate the pressure washer with the
inlet water screen removed. This screen helps
keep abrasive sediment out of the pump, which
could clog or scratch the pump. Keep this screen
clean.
DO NOT pump caustic materials; such materials
may corrode the pump components.

MAINTENANCE
SHUTDOWN, FLUSHING
AND STORAGE , .
Observing regular maintenance intervals helps ensure
that you get maximum petformance and life fromthe
pressure washer.
WARNING
Pressure Relief Procedure
There is a break-in period for the engine and pump.
After changing the oil in these components following
their respective break-in periods, the interval between
required changesis longer.
To reduce the' risk of serious bodily injury,
including fluid injection and splashing
inthe eyes,
or on the skin, always follow this procedure
whenever you stop spraying for more than10
minutes, when shutting down, and before
checking or repairing any part of the system.
1. Engage the trigger safety latch.
If the unit is operating in dusty conditions,. these
maintenance checks should be made more often.
