4. Setup
Follow these steps to set up your pressure washer before operation.
- Attach the Handle: Secure the handle to the main unit if it is not pre-assembled. Ensure it clicks into place or is fastened with provided screws.
- Connect High-Pressure Hose: Attach one end of the high-pressure hose to the outlet on the pressure washer unit and the other end to the spray gun. Ensure connections are tight to prevent leaks.
- Connect Water Supply: Attach the water inlet connector to the pressure washer's water inlet. Connect a standard garden hose (not included) to the water inlet connector and to a cold water tap. Ensure the garden hose is free of kinks and has a minimum diameter of 1/2 inch.
- Connect Power: Plug the power cord into a properly grounded electrical outlet. Ensure the outlet is suitable for outdoor use and protected by a Residual Current Device (RCD) if required by local regulations.
- Prime the Pump: Before turning on the power, turn on the water supply fully. Squeeze the trigger on the spray gun to allow water to flow through the system and expel any air. Continue until a steady stream of water emerges from the nozzle. This primes the pump and prevents damage.

5. Operating Instructions
Once the pressure washer is set up and primed, you can begin operation.
- Turn On the Unit: Locate the rotary ON/OFF switch on the front of the unit and turn it to the 'ON' position. The motor will start.
- Engage Spray Gun: Point the spray gun at the surface to be cleaned, ensuring it is a safe distance away. Squeeze the trigger to begin spraying. The motor will run continuously while the trigger is pressed.
- Adjust Nozzle: The included adjustable nozzle allows you to change the spray pattern from a concentrated jet to a wider fan spray. Rotate the nozzle head to achieve the desired pattern for your cleaning task.
- Using Detergent (Optional): If using detergent, fill the detergent bottle with an appropriate pressure washer-safe cleaning solution. Attach the detergent bottle to the spray gun. The pressure washer will automatically draw detergent when operating at low pressure (usually achieved by a specific nozzle setting or by attaching the detergent bottle).
- Cleaning Technique: Start spraying from a distance of approximately 30 cm (12 inches) and gradually move closer, observing the cleaning effect. Avoid spraying directly into electrical components or delicate surfaces.
- Shutting Down: When finished, release the spray gun trigger. Turn the rotary ON/OFF switch to the 'OFF' position. Turn off the water supply. Squeeze the spray gun trigger to release any remaining pressure in the system. Disconnect the power cord.

6. Maintenance
Regular maintenance ensures optimal performance and extends the life of your pressure washer.
- Clean Nozzle: If the nozzle becomes clogged, use the provided nozzle cleaning pin to clear any debris.
- Drain Water: After each use, ensure all water is drained from the pump, hose, and spray gun to prevent freezing damage in cold weather. Run the unit for a few seconds with the water supply off and the trigger squeezed until no more water comes out.
- Clean Water Inlet Filter: Periodically check and clean the water inlet filter to prevent debris from entering the pump.
- Storage: Store the pressure washer in a dry, frost-free location. Coil the high-pressure hose and power cord neatly.
- General Cleaning: Wipe down the exterior of the unit with a damp cloth. Do not use harsh chemicals.
