Thermal Relief Valve

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

Bypass Mode: Allows water tore-circulatewithin 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.

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.

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 nozzle - (white) 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 Pressurepressure Regulator

regulator Knob on thepump.

Turn the pressure regulator knob counterclock-

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

DO NOT try to turn pressure regulator

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

READ AND UNDERSTAND ALL WARNINGS BEFORE STARTING UNIT

When using the high pressure setting, DO NOT allow the high pressure spray to come in contact with unprotected skin, eyes,

or with any pets or animals. Serious injury can occur.

Your washer operates at fluid pressures and velocities high enough to penetrate human and animal flesh, which could result in amputation or other serious injury. Leaks caused by loose fittings or worn or damaged hoses can result in injection injuries. DO NOT TREAT FLUID INJECTION AS A SIMPLE CUT! See a physician immediately!

NEVER fill fuel tank when engine is running or hot. Do not smoke when filling fuel tank.

NEVER fill fuel tank completely. Fill tank to 1/2" below bottom of filler neck to provide space for fuel expansion. Wipe any fuel spillage from engine and equipment before starting engine.

NEVER run engine indoors or in enclosed, poorly ventilated areas. Engine exhaust contains carbon monoxide, an odorless and deadly gas.

DO NOT let hoses come in contact with very hot engine muffler during or immediately after use of your pressure washer. Damage to hoses from contact with hot engine surfaces will NOT be covered by warranty.

NEVER pull water supply hose to move pressure washer. This could damage hose and/or pump inlet.

DO NOT use hot water, use cold water only.

NEVER turn water supply off while pressure washer engine is running or damage to pump will result.

DO NOT stop spraying water for more than two minutes at a time. Pump operates in bypass mode when spray gun trigger is not pressed. If pump is left in bypass mode for more than two minutes internal components of the pump can be damaged.

If you do not understand these precautions, please call 1-866-422-4286to speak to a service representative for further instructions.
