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 nozzle -
(white) 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.
PRESSURE WASHER
TERMINOLOGY (continued)
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.
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.
3. Adjust the pres-
sure regulator
on the pump.
Turn the pressure
regulator knob
counterclockwise
to lower pressure.
Refer to the
illustrations to identify your pres-
sure regulator. Once you have fin-
ished 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.
