OPERATION

PRESSURE WASHER TERMINOLOGY

PSI: Pounds per Square Inch. The unit of measure for water pressure. Also used for air pressure, hydraulic pressure, etc.

GPM: Gallons per Minute. The unit of measure for the flow rate of water. CU: Cleaning Units. GPM multiplied by PSI equals CU. Bypass Mode: Allows water to re-circulate within the pump when the gun trigger is

not pulled. This feature allows the operator to release the trigger gun and reposition themselves without having to turn the engine off in between cleaning actions.

9 - ENG

Page 10

WARNING: Do not allow the unit to run for more than two minutes without the gun trigger being pulled. This could cause overheating and damage to the pump. When the temperature inside the pump rises too high, the thermal relief valve will open and release a spray of water from the pump to lower the internal temperature. The valve will then close.

Thermal Relief Valve (P, Fig. 3): When the temperature inside the pump rises too high, this valve will open and release a gush of

water in an effort to lower the temperature inside the pump. The valve will then close.

Detergent Injection System: Mixes cleaners or cleaning solvents with the water to improve cleaning effectiveness.

Water Supply: All pressure washers must have a source of water.

The minimum requirements for a water supply are 20 PSI and 5 Gallons Per Minute. If your water source is a well, the garden hose length can only be 30ft. (9m) max.

WARNING: To reduce the possibility of contamination always protect

against backflow when connected to a potable water system.

PRESSURE WASHER OPERATING FEATURES

PRESSURE ADJUSTMENTS (FIG. 4)

The pressure setting is preset at the factory to achieve op ti mum pres sure and cleaning. If you need to lower the pres sure, it can be accomplished by these methods.

1. Back away from the sur face 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 How To Use Spray Wand.

3. This pressure washer’s high pressure pump is equipped with an additional feature that allows the pressure setting to be adjusted.

To lower the pressure, turn the pressure control knob on the pump counterclockwise to the desired pressure.
