4. Hose Installation
Connect the high-pressure hose, water supply hose, and detergent hose as shown in the diagram below.

- Water Supply: Connect a standard garden hose to the water inlet on the pump. Ensure the water source is clean and free of debris.
- High-Pressure Hose: Connect one end of the high-pressure hose to the pump outlet and the other end to the spray gun. Tighten all connections securely to prevent leaks.
- Detergent Hose: If using detergent, connect the small detergent hose to the designated inlet on the pump and place the filter end into a container of pressure washer safe detergent.
Operating Instructions
1. Pre-Start Checklist
- Check engine oil level.
- Check fuel level.
- Ensure all hose connections are tight.
- Open the water supply valve completely.
- Squeeze the spray gun trigger to purge air from the pump and hose until a steady stream of water emerges.
2. Starting the Engine
- Turn the engine switch to the "ON" position.
- Move the choke lever to the "CHOKE" position (for cold starts).
- Pull the recoil starter handle firmly until the engine starts.
- Once the engine starts, gradually move the choke lever to the "RUN" position.
- Allow the engine to warm up for a few moments.
3. Using Nozzle Tips
The pressure washer comes with various nozzle tips, each designed for different applications. Always select the appropriate nozzle for the task to avoid damage to surfaces.

- Red (0°): Concentrated, high-impact stream for stubborn stains and hard-to-reach areas. Use with extreme caution as it can damage surfaces.
- Yellow (15°): Narrow fan spray for intensive cleaning of small areas, such as removing paint or rust.
- Green (25°): Medium fan spray for general cleaning of decks, patios, and driveways.
- White (40°): Wide fan spray for gentle cleaning of vehicles, boats, and delicate surfaces.
- Black (Foam/Soap): Low-pressure spray for applying detergents or cleaning solutions.
To change nozzles, turn off the engine and squeeze the trigger to release any residual pressure. Pull back the collar on the spray wand and insert the desired nozzle. Release the collar to lock it in place.
4. Using the Foam Cannon
The included foam cannon can be used for applying a thick layer of soap. Fill the foam cannon reservoir with appropriate pressure washer detergent. Attach the foam cannon to the spray gun in place of a standard nozzle. Operate the pressure washer at low pressure (using the black soap nozzle if not using the dedicated foam cannon) to apply the foam.
