The pressure setting is preset at the factory to achieve op­ti­mum pres­
sure and cleaning. To lower the pres­sure, follow these instructions.
1.Back away from the sur­face to be cleaned. The further away you
are, the less the pressure will be on the surface to be cleaned.
2.Change to the 40˚ nozzle (white). This nozzle delivers a less
powerful stream of water and a wider spray pattern. Refer to
Spray Wand Nozzles.
Caution: DO NOT attempt to increase pump pressure. A higher
pressure setting than the factory set pressure may damage pump.
