3. Setup and Assembly

Follow these steps to prepare your pressure washer for first use:

1. Add Engine Oil: Remove the oil dipstick/fill cap. Using a funnel, carefully pour SAE 10W-30 motor oil into the engine crankcase until the oil level reaches the 'L' mark on the dipstick. Do not overfill. Securely replace the dipstick/fill cap.
2. Add Fuel: Remove the fuel cap. Pour fresh, unleaded gasoline into the fuel tank. Do not overfill. Securely replace the fuel cap.
3. Connect High-Pressure Hose: Attach one end of the high-pressure hose to the pump outlet and the other end to the spray gun. Ensure connections are tight.
4. Connect Water Supply: Insert the filter screen into the water inlet of the pump. Connect a garden hose (minimum 5/8 inch diameter) to the water inlet. Ensure the garden hose is free of kinks and fully open the water source.
5. Purge Air from Pump: Squeeze the trigger on the spray gun until a steady stream of water flows from the nozzle, indicating that air has been purged from the pump.

4. Operating Instructions

Starting the Engine

1. Ensure all connections are secure and the water supply is on.
2. Turn the engine switch to the "ON" position.
3. Move the choke lever to the "CHOKE" position (if the engine is cold).
4. Move the fuel valve to the "ON" position.
5. Pull the recoil starter handle slowly until resistance is felt, then pull briskly to start the engine.
6. Once the engine starts, gradually move the choke lever to the "RUN" position.

Using Quick-Connect Nozzles

Your pressure washer comes with multiple quick-connect nozzles, each designed for a specific spray pattern and intensity:

• Red (0°): Pinpoint stream for intense cleaning of small, tough spots. Use with extreme caution.
• Yellow (15°): Narrow fan spray for concentrated cleaning of hard surfaces.
• Green (25°): Medium fan spray for general cleaning of most surfaces.
• White (40°): Wide fan spray for gentle cleaning of delicate surfaces.
• Black (Chemical/Soap): Low-pressure stream for applying detergent.

To change a nozzle, pull back the collar on the spray gun wand, insert the desired nozzle, and release the collar to lock it in place. Always ensure the engine is off and the trigger is released before changing nozzles.

Applying Detergent

Fill the onboard detergent tank with pressure washer-safe detergent. Attach the black (chemical/soap) nozzle to the spray gun. The pressure washer will automatically draw detergent when operating at low pressure. After applying detergent, switch to a high-pressure nozzle (e.g., green or yellow) to rinse the surface thoroughly.

Shutdown Procedure

1. Turn the engine switch to the "OFF" position.
2. Turn off the water supply.
3. Squeeze the spray gun trigger to relieve any remaining system pressure.
4. Disconnect the garden hose and high-pressure hose.

5. Maintenance

Regular maintenance ensures optimal performance and extends the life of your pressure washer. Always perform maintenance with the engine off and the spark plug wire disconnected.

Engine Maintenance

• Check Oil Level: Before each use, check the engine oil level and add oil if necessary.
• Change Oil: Change the engine oil after the first 5 hours of use, then every 50 hours or annually.
• Clean Air Filter: Clean the air filter every 25 hours or more often in dusty conditions. Replace if damaged.
• Spark Plug: Inspect and clean the spark plug annually. Replace if worn.

Pump Maintenance

• Inspect Water Inlet Filter: Regularly check the water inlet filter for debris and clean it as needed.
• Winterization: If storing the pressure washer in freezing temperatures, use a pump protector or antifreeze solution to prevent damage.

Storage

Before storing for extended periods, drain all fuel from the tank and carburetor. Run the engine until it stops from lack of fuel. Store the unit in a clean, dry area away from direct sunlight and extreme temperatures.
