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. Change to the 40º (white)
nozzle - this nozzle delivers a less
powerful stream of water and a
wider spray pattern.
DO NOT attempt to
increase pump
pressure. A higher pressure setting
than the factory set pressure may
damage pump.
3. Adjust the
pressure
regulator
on the
pump. Tu rn
the
pressure
regulator
knob counterclockwise to lower
pressure. Refer to the illustrations
to identify your pressure regulator.
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.
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. GPM x PSI = CU
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.
Bypass Mode: Allows water to
re-circulate within pump when the gun
trigger is not pulled.
Allowing the unit to
run for more than
two minutes without the gun trigger
pulled could cause overheating and
damage to the pump.
Thermal Relief Valve:
When the temperature
inside the pump rises too
high the valve will open
and release a gush of
water in an effort to lower
the temperature inside
the pump. The valve will then close.
Chemical Injection System: Mixes
cleaners or cleaning solvents with the
water to improve cleaning
effectiveness.
