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.

*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.
