NOTICE

ALCOHOL BLENDS

Using gasoline with an alcohol blend greater than 10% (E10) will damage the engine. Damage caused by using an alcohol blend of 15% (E15), 85% (E85), or any other alcohol blend higher than 10% (E10) is not covered under warranty. To avoid engine damage caused by an alcohol blend that is too high, use gasoline with 10% (E10) alcohol or lower.

NOTICE

GASOLINE ADDITIVES

The use of fuel system cleaning additives can damage the engine and fuel systems. Damage caused by the use of fuel system cleaning additives is not covered by warranty. To avoid engine and fuel system damage, do not use any fuel system cleaning additives.

NOTICE

GASOLINE STORAGE

It is important to prevent gum deposits from forming in essential fuel system parts, such as the carburetor, fuel filter, fuel hose or tank during storage. Alcohol-blended fuels (also called gasohol, ethanol, or methanol) attract moisture, which leads to separation and formation of acids during storage. Acidic fuel and gum deposits can damage the engine's fuel system while in storage. Damage caused by the use of old, stale, or contaminated fuel are not covered under warranty.

NOTICE

DO NOT OVERFILL FUEL TANK

Overfilling the fuel tank can result in carbon canister damage (if equipped), poor engine performance, and void the warranty. To avoid these hazards, do not fill the fuel tank above the maximum level.

1. Check fuel with the engine off and pressure washer on a level surface.
2. Remove fuel tank cap, check fuel level, then fill fuel tank if needed.
3. Do not use gasoline that is older than 30 days. Use only clean and fresh regular unleaded gasoline with a minimum octane rating of 87. Do not mix oil with gasoline. Do not use gasoline that contains more than 10% ethyl alcohol. E15, E20, and E85 are not approved fuels and should not be used.
4. Do not fill the fuel tank above the maximum fuel level to allow room for fuel expansion.
5. Replace fuel tank cap. Never run engine without fuel cap installed.

NOTE: Using a fuel stabilizer (sold separately) when storing gasoline can help prevent problems related to storing ethanol alcohol blended gasoline. Always follow the instructions provided by the fuel stabilizer manufacturer to mix and use correctly.

OPERATING CHECKLIST

Attempting to start the engine incorrectly or using the pressure washer incorrectly can result in engine and/or pressure washer damage, and may cause serious injury or death. To avoid these hazards, be sure to read, understand, and follow the steps outlined in the OPERATING CHECKLIST section of the owner's manual before starting the engine, and follow all the guidelines for proper use of the pressure washer.

PUMP DAMAGE

Running the pressure washer for more than two minutes without the spray gun trigger pulled will overheat the pump and possibly cause damage. The thermal relief valve will open and spray water to help cool the pump as it overheats. Never tamper with the thermal relief valve. To avoid overheating the pump, shut off the engine if not being used for longer than two minutes.

Starting the Engine

1. Complete the steps in the OPERATING CHECKLIST section of this manual before starting the engine. Failure to do so could cause damage to the pump or engine. If needed, refer to your Engine Owner's Manual for specific starting instructions.
   The water source should be connected, turned on, any air purged from the system, and the trigger lock placed in the locked position.
2. Slide the fuel valve to the ON position (if equipped).
3. Slide the throttle to the RUN position (if equipped).
4. If equipped, move the choke to CHOKE (closed) for starting a COLD engine. Move to RUN (open) for a WARM engine.

NOTE: If the engine should not start after two pulls, squeeze the gun trigger to release stored pressure. Then, try again to start the engine.

RAPID RETRACTION

Rapid retraction (also known as kickback) of the engine recoil starter cord will pull your hand and arm towards the engine faster than you can let go of the handle resulting in sprains, broken bones, lacerations, and/or traumatic amputations. Kickback is often caused by internal engine failure, and/or improper starting techniques. To avoid kickback follow the appropriate maintenance schedule, starting instructions and have repair work done by an authorized service center.

1. Once the engine starts, slowly move the choke lever (if equipped) to RUN (open) as the engine runs. If the engine falters, move the choke toward CHOKE (closed) until the engine has warmed up.

1. Allow engine to warm for 1-2 minutes before using the product, occasionally pulling the spray gun trigger to allow water to flow through the pump and avoid overheating and causing damage to the pump.

NOTE: Always secure trigger lock when spray gun is not in use to prevent accidental operation. Never permanently secure trigger in pull-back (open) position.

NOTICE

PUMP DAMAGE

Turning off the water supply to your pump with the engine running will damage the pump. Damage caused by running the pump without water is not covered under warranty. To avoid this hazard always turn off the engine before shutting off the water supply.

1. Set the trigger lock on the spray gun.
2. Slide the throttle to the SLOW position (if equipped).
3. Turn the engine switch to the OFF position.
4. Slide the fuel valve to the OFF position (if equipped).
5. Turn off the water supply.
6. Release the trigger lock then squeeze the spray gun trigger to relieve the pressure in the hose and pump.
7. Allow the engine to cool completely before handling and storage.

OPERATION TIPS

Terms

• PSI - Pounds per square inch (PSI) is the unit to measure the pressure of water. In relation to a pressure washer, the higher the PSI number, the greater the pressure and stripping power produced.
• GPM - Gallons per minute (GPM) is the flow rate of water. In relation to a pressure washer, the greater the GPM, the greater the flow or rinsing power produced.
• CU - Cleaning units express the efficiency of the pressure washer. Cleaning units are calculated by multiply the PSI by the GPM. The higher the CU, the more efficient the pressure washer.

Preparation

• Read all warning and instructions in this and all manuals that came with the pressure washer.
• Remove all toys, bikes, lawn furniture, etc. from the work area if they are not to be cleaned.
• Sweep any loose dirt and debris from the surface you will be pressure washing.

• Cover nearby plants to avoid damaging them with the pressure washer spray.

• Use caution when spraying windows. Always use the white, 40 ^® nozzle and stay at least 4 feet away.

• Lay tarps down to collect paint chips and other debris blown off by the spray. Exterior paints used before 1977 may contain lead and will produce chips that will need to be collected and disposed of at a hazardous waste facility.
• To minimize water infiltration to the pressure washer motor, locate the pressure washer as far as possible from the cleaning site during operation.

Pressure Washing

- A wider spray equals faster cleaning, while a tighter spray equals deeper cleaning.

- Keep the nozzle about 4 feet away from siding to avoid damage.

- Start washing siding at the bottom and work your way up, then rinse from the top down.

- Avoid driving water up behind siding.

- Use overlapping strokes for even cleaning.

• Work in small areas to keep the soap from drying.

- Do not aim the nozzle straight at the surface. Hold the wand at a 45^ angle to the surface at a distance that cleans well without causing damage.

Adjusting Surface Pressure

- Back away from the surface to be cleaned. The further you position the nozzle from the surface to be cleaned, the lower the pressure to reach the surface.

- Change to the white, 40^ nozzle. This nozzle produces a lower pressure, wider width spray.

Adjusting Unloader Hand Control Knob to Adjust Pressure

HIGH PRESSURE

Do not remove the unloader hand control knob. Do not overtighten the unloader hand control knob. Overtightening the knob past the built-in stop may result in serious injuries, the knob breaking and/or costly repairs. Do not attempt to increase the pressure past the factory preset pressure.

The highest pressure setting is preset at the factory to achieve optimum pressure for cleaning. If you should need to lower the pressure, your unit may be equipped with an unloader hand control knob that allows you to adjust the pressure. The unloader hand control knob style may differ from those shown below.

- If equipped with an unloader hand control knob, lower the pressure by turning the unloader hand control knob counter-clockwise to the desired pressure.

- Turn the unloader hand control knob clockwise until it stops to return to the highest pressure setting preset at the factory.
