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.
DO NOT attempt to
increase pump
pressure. A higher pressure
setting than the factory set
pressure may damage pump.
HOW TO USE
IMPORTANT: Read and understand
how to use the pressure washer
before operating.
HOW TO USE SPRAY WAND:
Your pressure washer is equipped with
a multi-adjustable spray wand with
both high and low pressure settings.
The high pressure setting is for
cleaning and rinsing, the low pressure
setting is for applying chemicals or
cleaning solutions to surfaces.
When using the high
pressure setting,
DO NOT allow the jet-like spray to
come in contact with unprotected
skin, eyes, or with any pets or
animals. Serious injury can occur.
Risk of injection or
injury to person.
DO NOT direct discharge stream
toward persons.
For high pressure operation, pull back
the nozzle of the multi-adjustable
spray wand as shown.
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.
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 will rise to a
dangerous level and could 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 extreme 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. The thermal relief
valve is part of the pump and is not
visible to the user.
Chemical Injection System: Mixes
cleaners or cleaning solvents with the
pressurized 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.
