BEFORE STARTING THE ENGINE
To operate the engine you wilt need to do the following.
A CAUTION: Always check engine oil level before
every start. Running engine low of oil or out of oil
could result in serious damage.
A CAUTION: Always check pump oil level before
every start. Running pump low on oil could result
In pump damage.
Adding Pump Oil
Before running the high pressure washer, check the
pump oil level by viewing the sight glass on the side of
the pump. When properly filled, the oil will be at the
half way point marked by the two triangles. Your
pressure washer pump is shipped with oil. Add only if
oil level is lower than the half way point on the sight
glass.
Do not overfUl. Use 30 weight non-detergent oil
if necessary.
A CAUTION: Do Not use engine oil that has been
shipped with your unit in your pump. Engine oil is
detergent and your pump uses a non-detergent
oil. Detergent oil can cause damage to your pump.
f -sp q ^ ^
STARTING TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
Air cooled engines run hotter than automotive engines.
The use of multi-viscosity oil such as (10W-30, etc.) in
ambient temperatures above 40'’F (4°C) will result in
higher than norma! oil consumption. If multi-viscosity
oil is used, check the oil level more frequently to
prevent any posssible engine damage due to lack of
lubrication.
Use of SAE30 oil below 40°F (4°C) will result in hard
starting and possible engine damage due to inad
equate lubrication.
Gasoline
Your pressure washer engine is 4 cycle. Use unleaded
fuel only.
A CAUTION: Do not overfill the fuel tank. Always
allow room for fuel expansion.
A WARNING: Never fill fuel tank indoors. Never
fill fuel tank when engine is running or hot. Do
not smoke or have open flame when filling fuel
tank.
Use clean, fresh, regular unleaded gasoline with a
minimum of 85 octane. Do not mix oil with gasoline.
If unleaded fuel is not available, leaded fuel may be
used.
IMPORTANT; It is important to prevent gum deposits
from forming in essentia! fuel system parts such as the
carburetor, fuel filter hose or tank during storage. Also,
experience indicates that alcohohblended fuels {called
gasohol or using ethanol or methanol) can attract mois
ture which leads to separation and formation of acids
during storage. Acidic gas can damage the fuel system
of an engine while in storage. To avoid engine problems,
the fuel system should be emptied before storage of 30
days or longer. Never use engine or carburetor cleaner
products in the fuel tank or permanent damage may
occur.
NOTE; Never start pressure washer without water
source turned on and connected to pressure washer.
To Start Your Pressure Washer
Make sure fuel shutoff valve is turned to the open
position. Turn couner-ctockwise to open.
Squeeze trigger on pressure washer wand to relieve air
pressure caused by turning on the water. Water will
spew out of the gun in a thin stream. This will make it
easier to start the engine.
Engage the safety latch on the spray gun. This locks
the trigger in place and keeps you from accidentally
spraying a high pressure stream.
• On the engine there is a choke/run lever. Place lever
to the choke position.
CHOKE
LEVER
• Remove gas cap.
• Add unleaded gasoline, slowly, to fuel tank.

NOTE: While doing this procedure make sure water
supply is turned on and flowing to the unit. NEVER run
unit without water supply running through pump.
• Next shut off engine and disconnect the water supply.
• Disconnect the spark plug wire and remove the spark
plug.
Add one teaspoon of oil through the spark plug hole.
Place rag over spark plug hole and pull the recoil a
few times to lubricate the combustion chamber.
Replace the spark plug, but do not connect the spark
plug wire.
Pump Preparation
• Be sure engine switch is in “OFF” position and spark
plug wire has been removed from spark plug.
• Pull the trigger on the spay gun to release the
pressure in the high pressure hose. Detach high
pressure hose and garden hose from the unit.
• Puli the recoil on the engine 4 to 6 times to discharge
remaining water in pump.
• Tip the unit on the end with the water inlet fitting
pointing upward.
• Pour approximately 1/4 cup of non-toxic R.V. anti
freeze down the fitting where the water hose attaches
to the pump.
• Set unit upright and pull starter handle on engine 4 to
6 times to circulate anti-freeze in pump until anti
freeze is discharged from the pump.
