OPERATION

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.

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.

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 nozzle for the job to be performed.

*Caution: The high-pressure spray from your pressure washer 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.

Changing Nozzles on Spray Wand

Danger: Risk of fluid injection. Do not direct discharge stream toward persons, unprotected skin, eyes or any pets or animals. Serious injury will occur.

warning: Flying objects could cause risk of serious injury. Do Not attempt to change nozzles while pressure washer is running. Turn engine off before changing nozzles.
