PRESSURE WASHER
TERMINOLOGY
NOTE: Become familiar with this ter- minology 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 will rise to a dan- gerous level and damage internal components of the pump.Any dam- age 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 temper- ature inside the pump rises too high. This valve will then release a gush of water in an effort to lower the tem- perature 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 clean- ing.
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.
2.Reduce the speed of the gaso- line engine (RPM). Slow the engine down and the water pres- sure will go down with it.
DO NOT attempt to
increase pump
pressure. A higher pressure set- ting than the factory set pressure may damage pump.
TO USE WAND
Your pressure washer is equipped with a
Risk of injection or injury to person. Do not direct discharge stream toward
persons, unprotected skin, eyes, or towards any pets or animals. Serious injury can occur.
For high pressure operation, pull back the nozzle of the
