OPERATION
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 equals CU.
Bypass Mode:
Allows water to re-circulate within the pump when the gun trigger
is not pulled. This feature allows the operator to release the trigger gun and reposition
themselves without having to turn the engine off in between cleaning actions.
WARNING:
Do not allow the unit to run for more than two minutes
without the gun trigger being pulled. This could cause overheating
and damage to the pump. When the temperature inside the pump
rises too high, the thermal relief valve will open and release a spray
of water from the pump to lower the internal temperature. The valve
will then close.
Thermal Relief Valve (P, Fig. 5):
When the temperature inside the
5
P
pump rises too high, this valve will open and release a gush of water in
an effort to lower the temperature inside the pump. The valve will
then close.
Detergent 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. If your water
source is a well, the garden hose length can only be 30 ft. (9 m) max.
WARNING: To reduce the possibility of contamination always
protect against backflow when connected to a potable water system.
PRESSURE WASHER OPERATING FEATURES
PRESSURE ADJUSTMENTS
The pressure setting is preset at the factory to achieve op ti mum pres sure and cleaning. If
you need to lower the pres sure, it can be accomplished by these meth ods.
1. Back away from the sur face to be cleaned.
The further away you are,
the less the pressure will be on the surface to be cleaned.
