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.
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. Rotate the nozzle at the end of
the multi-adjustable spray wand
to widen the fan spray. The
wider fan spray will minimize the
pressure on the surface to be
cleaned.
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.
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
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.
