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.
2 Reduce the speed of the gasoline engine (RPM). Slow the engine down and
the water pressure will go down with it.
3. Adjust the pressure regulator on the pump. Turn the
pressure regulator knob counterclockwise to lower
pressure.
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-in stop or damage to
pump will result.
