4. Setup and Assembly
Follow these steps to assemble and prepare your pressure washer for use.
- Attach High-Pressure Hose: Connect one end of the high-pressure hose to the outlet on the main unit and the other end to the spray gun. Ensure connections are secure to prevent leaks.
- Connect Water Supply: Attach a standard garden hose to the water inlet connector on the pressure washer. Ensure the water supply is turned on fully before starting the unit. The maximum water inlet temperature is 140°F (60°C).
- Install Nozzle: Select the desired nozzle (e.g., 25° for general cleaning) and insert it into the quick-connect collar on the spray gun wand. Pull back the collar, insert the nozzle, and release the collar to lock it in place.
- Fill Detergent Tank (Optional): If using detergent, fill the built-in detergent tank with an appropriate pressure washer-safe cleaning solution.

5. Operating Instructions
Follow these steps for safe and effective operation of your pressure washer.
- Power On: Plug the power cord into a grounded electrical outlet.
- Purge Air: Before turning on the unit, squeeze the trigger on the spray gun to allow water to flow through the system and purge any air. This helps protect the pump.
- Start Pressure Washer: Turn the power switch to the "ON" position. The motor will start, and the pump will build pressure.
- Begin Cleaning: Squeeze the trigger to start the high-pressure spray. Release the trigger to activate the Total Stop System (TSS), which automatically shuts off the pump to save energy and prolong its life.
- Adjust Spray Pattern: Change nozzles as needed for different cleaning tasks. Refer to the nozzle guide below.
- Applying Detergent: To apply detergent, use the black soap nozzle. The pressure washer will automatically draw detergent from the tank at low pressure.
- Shut Down: When finished, turn the power switch to "OFF," turn off the water supply, and squeeze the trigger to release any remaining pressure in the system. Disconnect the garden hose and power cord.
