Operating Instructions
Before starting, ensure all connections are secure and the water supply is turned on.
- Priming the Pump: Before switching on the unit, 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.
- Starting the Unit: Turn on the power switch on the pressure washer. The Total-Stop System (TSS) will activate the motor only when the spray gun trigger is pressed.
- Using the Spray Gun and Nozzle: Direct the nozzle towards the surface to be cleaned. Adjust the distance and angle to achieve the desired cleaning effect. Start with a wider spray pattern and lower pressure on delicate surfaces.
- Detergent Application (Optional): Fill the detergent tank with an approved pressure washer detergent. Attach the detergent tank to the spray gun or follow specific instructions for your model to engage the detergent function. Apply detergent to the surface, allow it to soak for a few minutes (do not let it dry), then rinse thoroughly with clean water.
- Hose Reel Usage: The integrated hose reel with guide allows for easy winding and unwinding of the high-pressure hose, preventing tangles and ensuring convenient storage. Use the crank to retract the hose after use.
- Total-Stop System (TSS): The TSS automatically switches the motor on when the trigger is pressed and off when released. This protects the motor, extends its lifespan, and conserves energy.

Maintenance
Regular maintenance ensures the longevity and optimal performance of your pressure washer.
- After Each Use: Turn off the power, disconnect the power cord, and turn off the water supply. Squeeze the spray gun trigger to release any remaining pressure in the system.
- Draining Water: Disconnect all hoses and drain any residual water from the pump and hoses to prevent freezing damage in cold weather.
- Nozzle Cleaning: If the nozzle becomes clogged, use the provided nozzle cleaning tool (if applicable) or a thin wire to clear any debris.
- Water Inlet Filter: Regularly 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. Wind the high-pressure hose onto the integrated reel and secure the spray gun in its holder.
