BASIC ELEMENTS OF ENGINE

Refer to the engine manual for location and operation of engine controls.

Choke Control: Opens and closes carburetor choke valve

Throttle Control Lever: Controls engine speed.

Starter Grip: Pulling starter grip operates recoil starter to crank engine.

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 through

the pressure washer.

CU: Cleaning Units. GPM multiplied by PSI.

Bypass Mode: In Bypass Mode, the pump is recirculating water because the

trigger of the spray gun is not pulled. If unit is left in bypass mode for more than

two (2) minutes, the water temperature will rise to a dangerous level and could

damage internal components of the pump. Any damage to pump due to these

causes will not be covered under warranty.

DO NOT allow your unit to operate in bypass mode for more

than two minutes at any time. Overheating of pump can

cause damage to pump.

Thermal Relief Valve: In an effort to prevent extreme damage, pumps are

equipped with a thermal relief valve. This valve will open when the temperature

inside the pump rises too high. This valve will then release a gush of water in an

effort to lower the temperature inside the pump. Immediately after this occurs,

the valve will close. The thermal relief valve is part of the pump and is not visible

to the user.

Chemical Injection System: Mixes cleaners or cleaning solvents with the

pressurized 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. Rotate the nozzle at the end of the multi-adjustable spray wand to

widen the fan spray. The wider fan spray will minimize the pressure on the

surface to be cleaned.

DO NOT attempt to increase pump pressure. A higher

pressure setting than the factory set pressure may

damage pump.
