adjust spray pattern because you could be injured.
Stopping Your Pressure Washer
A CAUTION: Do not run pump without the water
supply connected and turned on. Failure to do so
will result in pump damage.
Move throttle control to the stop position to turn
pressure washer off.
THROTTLE CONTROL
• Simply shutting OFF engine will not release pressure
in the system. After engine has stopped, squeeze the
trigger on the spray gun for about 3 seconds to relieve
pressure. Spray stream will decrease in length.
IMPORTANT: This unit is equipped with a thermal relief
valve. If unit is allowed to run for several minutes
without pressing the trigger on the spray gun, several
drops of water may be released through this valve to
cool the unit. The heated water will be purged from the
bottom of the pump.
Engine Oil
Your unit has been shipped without oil In the engine.
A bottle of SAE 30 weight oil is included in the carton.
Remove oil dip stick located on top of the engine. Oil
capacity is about 20 ounces of oil. The oil dip stick is
clearly marked with a line that tells you when unit has
enough oil. To check oil, place dipstick into oil fill.
Tighten dipstick then remove.Do not fill above this
point. Pour slowly.
NOTE: When adding oil to the engine crankcase, use
a high quality detergent oil classified for Service SF,
SG, SH, rated SAE 30 weight. Use no special addi
tives. Select the oil’s viscosity grade according to your
expected operating temperatures.
colder <
Synthetic 5W-30 1
Although multi-viscosity oils (5W30,10W30, etc.)
improve starting in cold weather, these multi-viscosity
oils will result in increased oil consumption when used
above 40°F Check your engine oil level more frequently
to avoid possible damage from running low on oil. Oil
sump capacity is about 20 ounces.

Gasoline
Your pressure washer engine is 4 cycle. Use fresh
unleaded fuel only.
BI!
^ CAUTION: Do not overfill the fuel tank. Always
allow room for fuel expansion.
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 unavailable leaded fuel may be used.
IMPORTANT: It is important to prevent gum deposits
from forming in essential fuel system parts such as the
carburetor, fuel filter hose or tank during storage. Also,
experience indicates that alcohol-blended fuels (called
gasohol or using ethanol or methanol) can attract
moisture 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 perma
nent damage may occur.
Squeeze trigger on pressure washer wand to relieve
air pressure caused by turning on the water. Water
win 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.
SAFETY
LATCH
NOTE: Never start pressure washer without water
source turned on and connected to pressure washer.

carburetor, fuel filter hose or tank during storage. Also,
experience indicates that alcohol-blended 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.
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 spray gun to release the
pressure in the high pressure hose. Detach high
pressure hose and garden hose from the unit.
• Pull 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.
• If unit will be stored where temperatures fall below
32°F, 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.
