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.
NOTICE: DO NOT attempt to increase pump pressure. A higher
pressure setting than the factory set pressure may damage pump.
3. Reduce the speed of the gasoline engine (RPM). Slow the engine
down and the water pressure will go down with it.
