BEFORE STARTING THE ENGINE

To operate the engine you will need to do the following.

NOTE: Your pressure washer pump is a sealed pump you should never have to add or change the oil

every start. Running engine low of oil or out of oil could result in serious damage.

Engine Oil Your unit has been shipped without oil in the engine.

A bottle of SAE 30 weight oilis included in the carton. Remove oildip 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.

wa e en0neoeve eoreI

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 runfor 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.

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 <...... -------4O°F > warmer

Synthetic 5W-30 I SAE 30

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.

allow room for fuel expansion.

_, AUTION: Do not overfill the fuel tank. Always

_. WARNING; Never fill fueI tank indoors. Never

fill fuel tank when engine is running or hot, Do

not smoke or have open flame when tiltingfuel

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 ormethanol) 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. Toavoid 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 willspew 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.

NOTE: If engine does not start right away, squeeze the trigger on the gun to relieve water pressure caused by turning on the water. Water will spew

out of the gun in a thin stream. This will make it easier to pull start the engine. If more than five pulls are required, place choke lever back to run

position.

• When engine starts, gradually move choke lever to

RUN position.

• Connect high pressure hose to discharge on pump.

• Connect the garden hose to the water spout and turn water supply on.

• For hot engine restarts, make sure throttle is in the rabbit (High speed) position and the choke lever is in

the RUN position.

• Grasp the starter grip and pull slowly until resistance

is felt; then pull firmly to start engine.

How To Use Your Pressure Washer

Using Soaps/Chemicals

On the end of your spray gun is a nozzle that you can slide forward and backward and that you can also twist from side to side. With the adjustable nozzle you

can adjust the spray pattern to either high pressure or low pressure. You can also adjust the spray so it is

concentrated in a stream pattern or expanded into a fan pattem.

• Slide the nozzle forward for low pressure. Pull nozzle back for high pressure.

HIGH PRESSURE

LOW PRESSURE

• To adjust your spray pattern twist the nozzle

clockwise for fan spray or counterclockwise for stream spray.

FAN SPRAY

STREAM SPRAY

• For most effective cleaning, keep spray nozzle

between 8 and 24 inches from cleaning surface.

IMPORTANT" If you get spray nozzle too close, especially on high pressure, you may damage the surface you are cleaning.

• The pressure control knob is located on the pump. You can increase the pressure by turning the knob

clockwise or decrease the pressure by turning the knob counterclockwise.
