Pressure Adjustments
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.
. 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.
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 for the spray wand are stored in the nozzle holder (G) on
the panel assembly (F). Colors on the panel identify nozzle location
and spray pattern. Refer to the following chart to choose the correct

is capable of causing damage to surfaces such as wood, glass,
automobile paint, auto striping and trim, delicate objects such
as flowers and shrubs. Before spraying, check the item to
be cleaned to assure yourself that it is strong enough to resist
damage from the force of spray.
