DeWalt DPH3100 OPERATION Pressure Adjustments, Spray Wand Nozzles Fig, English, Spray Pattern

English

NOTE: The high pressure pump is maintenance free and requires no oil, if there is a problem with the pump contact a DeWALT factory service center, a DeWALT authorized service center or other qualified service personnel.

Warning: Risk of bursting. Use a tire pressure gauge to check the tires pressure before each use and while inflating tires; see the tire side- wall for the correct tire pressure.

NOTE: Air tanks, compressors and similar equipment used to inflate tires can fill small tires similar to these very rapidly. Adjust pressure regulator on air supply to no more than the rating of the tire pressure. Add air in small increments and frequently use the tire gauge to prevent over inflation.

OPERATION

Pressure Adjustments

The pressure setting is preset at the factory to achieve opti­mum­ pressure­ and cleaning. To lower the pressure,­ follow these instruc- tions.

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 (B) on the panel assembly (A). 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.
