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. GPM x PSI = CU

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.

Bypass Mode: Allows water to re-circulate within pump when the gun trigger is not pulled.

Allowing the unit to run for more than

two minutes without the gun trigger pulled could cause overheating and damage to the pump.

Thermal Relief Valve: When the temperature inside the pump rises too high the valve will open

and release a gush of water in an effort to lower

the temperature inside

the pump. The valve will then close.

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

PRESSURE WASHER OPERATING FEATURES

PRESSURE ADJUSTMENTS

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

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 40º (white) nozzle - this nozzle delivers a less powerful stream of water and a wider spray pattern.

DO NOT attempt to increase pump

pressure. A higher pressure setting than the factory set pressure may damage pump.

3. Adjust the pressure regulator on the

pump. Turn the pressure regulator

knob counterclockwise to lower pressure. Refer to the illustrations to identify your pressure regulator. Once you have finished using your pressure washer, return the pres- sure regulator to its original position by turning it clockwise.

DO NOT try to turn pressure regulator

knob past the built-in stop or damage to pump will result.
