WARNING: Read Owner’s Manual. Do not

attempt to operate equipment until you have read Owners Manual for Safety, Operation, and Maintenance Instructions.

Note: Included with your unit is a video cassette that demonstrates how to operate your pressure washer. If you have a video cassette recorder you should view the video before operation.

WARNING: Never adjust spray pattern when

spraying. Never put hands in front of spray nozzle to adjust spray pattern you could be injured.

Stopping Your Pressure Washer

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.

Before Starting The Engine

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

CAUTION: Always check engine oil level before 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 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.

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. This small amount of water will drip 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 additives. Select the oil’s viscosity grade according to your expected operating temperatures.

colder <——-----———40°F——————> warmer Synthetic 5W-30 l 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 20 ounces.

Gasoline

Your pressure washer engine is 4 cycle. Use unleaded fuel only.

CAUTION: Do not overfill the fuel tank.

Always allow room for fuel expansion.

D20590

WARNING: Never fill fuel tank indoors. To

avoid explosion and injury, never fill fuel tank when engine is running or hot. Do not smoke or have open flame when filling fuel tank.

8-ENG

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 permanent damage may occur.

CAUTION: Never start pressure washer without water source turned on and connected to pressure washer. Failure to do so will cause pump damage.

To Start Your Pressure Washer

• Remove gas cap.

• Add unleaded gasoline, slowly, to fuel tank.

• Do not overfill.

• 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.

SAFETY

LATCH

• On the engine there is a choke/run lever. Place lever to the choke position.

• On the engine there is a throttle control lever. Place throttle to the rabbit position. Always start engine with throttle in the rabbit (high speed) position.

CHOKE

• Connect garden hose to the water inlet on the pressure washer. Tighten by turning counterclockwise.

PUMP INLET

PUMP

DISCHARGE

• Connect high pressure hose to discharge on pump.

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

THROTTLE

CONTROL

(In Rabbit position)

• Grasp the starter grip and pull slowly until resistance is felt, then pull firmly to start engine.

NOTE: If engine does not start right away, squeeze the trigger on the gun 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 pull start the engine. If more than five pulls, place choke lever back to run position.

• When engine starts, gradually move choke lever to RUN position.

• 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.
