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

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.
3. Reduce the speed of the
gasoline engine (RPM). Slow the
engine down and the water
pressure will go down with it.
pressure. A higher pressure setting
than the factory set pressure may
damage pump.
