Built-in water filtration reduces the risk of debris entering the pump, supporting durability. Large wheels and ergonomic handles facilitate transport and positioning on uneven ground.

How to use

Connect the pressure washer to a suitable water supply and check the integrated filter for cleanliness before starting. Attach the high-pressure hose and select the required nozzle setting on the 3-in-1 head for the desired spray pattern or detergent use. Start the motor and allow pressure to build to operating level. Maintain a safe distance from the surface being cleaned and move the lance in smooth, overlapping passes to achieve even results. After use, switch off the machine, release any residual pressure, and store the hose and accessories on the unit to protect them from damage.

Usage recommendations

For effective and safe cleaning, use appropriate nozzle settings and the recommended pressure for different surfaces: lower pressure for painted or soft materials and higher pressure for hard, heavily soiled surfaces. Rinse surfaces after detergent application. Regularly inspect and clean the integrated water filter and avoid running the unit without a water supply to protect the pump.
