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.

Fuel Valve Lever: Opens / closes connection between fuel tank and carburetor.

PRESSURE WASHER TERMINOLOGY

NOTE: Become familiar with this terminology before operating.

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 can rise to a dangerous level and may 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 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.

Chemical Injection: Feeds cleaning agents into the pump to mix with the pressurized water and help in cleaning.

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.

HOW TO USE

IMPORTANT: Read and understand how to use the pressure washer before operating.

TO ADJUST PRESSURE

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.

DO NOT attempt to increase pump pressure. A higher pressure setting than the factory set pressure may damage pump.

2.Change to a wider spray pattern nozzle. See How to Use Wand paragraph in this section.

3.Reduce the speed of the gasoline engine (RPM). Slow the engine down and the water pressure will go down with it.
