OPERATION
PRESSURE ADJUSTMENT
Models 9032PW and 1340PW have a pressure adjustment knob located on the pump (see Figure 10). Turn the knob clockwise to increase the pressure. Turn the knob counter clockwise to decrease the pressure. DO NOT try and force the knob to turn. The knob may already be at either the lowest or highest setting.
If there is not a plastic adjustment knob located on the pump (See Figure 10), then the pressure cannot be adjusted. The only way to adjust the pressure is to move closer or further away from the cleaning surface and adjust the spray fan angle as shown in the next section.
ADJUSTING THE SPRAY FAN ANGLE
Your unit has quick connect tips that have a range of spray fan angles. Model 5525PW includes the black detergent and yellow 15° quick connect tips only.
Figure 10 - Camshaft pump pressure adjustment
The quick connect tips can be switched out from a 0° narrow high impact stream to a 65° wide fan spray.
A narrow stream has high impact force on the cleaning surface and results in maximum deep cleaning in a concentrated area. However, this narrow high impact spray can damage some surfaces, so use it cautiously. Not recommended for use on automotive paint, trim and vinyl siding.
The color of the tip shows what spray angle it is:
Red – 0° – Maximum Duty
Yellow – 15° – Heavy Duty
Green – 25° – General Duty White – 40° – Light Duty
Black – 65° – Low Pressure Detergent

A wide fan pattern will distribute the impact of the water over a larger area resulting in excellent cleaning action with reduced risk of surface damage. Clean large surface areas quickly using a wide fan pattern.
ANGLE TO THE CLEANING SURFACE
Figure 12 - Narrow high impact stream
When spraying water against a surface, you can generate maximum impact by striking the surface head on. However, this type of impact can cause dirt particles to embed in the surface and can prevent the desired cleaning action.
