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.
