PRESSURE
WASHER
TERMINOLOGY
NOTE: Become familiar with this
terminology
before operating.
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
through the pressure washer.
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 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 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:
Feeds cleaning
agents into the pump to mix with the
pressurized water and help in
cleaning.
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.
HOW TO USE
IMPORTANT:
Read and understand
how to use the pressure
washer
before operating.
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.
TO USE WAND
Your pressure washer is equipped
with a multi-reg 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.
Risk of injection
or
injury to person. Do
not direct
discharge
stream toward
persons,
unprotected
skin, eyes, or
towards
any pets or animals.
Serious
injury can occur.
For high pressure operation,
pull back
the nozzle of the multi-reg wand as
shown.
