Pressure Adjustments

The pressure setting is preset at the factory to achieve op ti mum
pressure and cleaning. To lower the pres sure, follow these instructions.
1. Back away from the sur face 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.
Spray Wand Nozzles (Fig. 1)
The nozzles (B) for the spray wand are stored in the nozzle holder on the
panel assembly. Colors on the panel identify nozzle location and spray
pattern. Refer to the following chart to choose the correct nozzle for
