2. Setup and Assembly
Follow these steps to correctly set up your pressure washer before first use:
- Unpack Components: Carefully remove all items from the packaging. Verify that all parts listed in the product diagram are present.
- Assemble Handle and Wheels: If not pre-assembled, attach the handle and wheels to the main unit according to the illustrations in the quick start guide. Ensure they are securely fastened.
- Connect High-Pressure Hose: Connect one end of the high-pressure hose to the high-pressure outlet on the pressure washer and the other end to the spray gun. Ensure connections are tight to prevent leaks.

- Connect Power: Plug the power cord into a grounded electrical outlet. Ensure the voltage matches the specifications of the unit.
3. Operating Instructions
Before starting, ensure all connections are secure and the water supply is turned on.
- Purge Air: Squeeze the trigger on the spray gun until a steady stream of water flows, indicating all air has been expelled from the system. This protects the pump.
- Start the Unit: Turn on the pressure washer using the power switch located on the unit.

- Select Nozzle: Choose the appropriate nozzle for your cleaning task. Different nozzles provide varying spray patterns and pressures. Always attach or remove nozzles only when the unit is off and pressure is released.
- Apply Detergent (Optional): If your model supports detergent application, fill the detergent tank with appropriate pressure washer detergent. Attach the detergent nozzle (if separate) or ensure the detergent function is activated. The pressure washer will draw detergent at low pressure.
- Begin Cleaning: Maintain a firm grip on the spray gun and stand on a stable surface. Keep a safe distance from the surface being cleaned to avoid damage.

- Shut Down: To stop operation, release the trigger, turn off the power switch, and turn off the water supply. Squeeze the trigger again to release any remaining pressure in the system.
4. Maintenance
Regular maintenance ensures the longevity and optimal performance of your pressure washer.
- After Each Use: Disconnect the water and power supply. Squeeze the trigger to release any remaining pressure in the hose and pump.
- Cleaning the Unit: Wipe down the exterior of the unit with a damp cloth. Do not use harsh chemicals or abrasive cleaners.
- Hose and Cord Inspection: Regularly inspect the high-pressure hose and power cord for any signs of damage, kinks, or wear. Replace damaged components immediately.
- Water Inlet Filter: Clean the water inlet filter regularly to prevent debris from entering and damaging the pump. Remove the filter, rinse it under running water, and reinsert.
- Storage and Winterization: For long-term storage or during freezing temperatures, ensure all water is drained from the pump, hoses, and spray gun to prevent damage from freezing. Store the unit in a dry, protected area.
