DAMAGE WHEN TRANSPORTING
OR STORING
The powerful spray from your pressure washer is capable of caus-
ing damage to surfaces such as wood, glass, automobile paint, auto
striping and trim, and delicate objects such as flowers and shrubs. Before spraying,
check the item to be cleaned to assure yourself that it is strong enough to resist
damage from the force of the spray. Avoid the use of the concentrated spray stream
except for very strong surfaces like concrete and steel.
Operating without flow of water will result in equipment damage. Operating the pres-
sure washer with water supply shutoff will void your warranty. You should never run

PRESSURE WASHER
High Pressure Pump: Increases the
pressure of the water supply.
Engine: Drives the high pressure
pump.
High Pressure Hose: Carries the
pressurized water from the pump to
the gun and wand.
Spray Gun: Connects with wand to
control water flow rate, direction, and
pressure.
Multi-Reg Wand: Has a spray nozzle
which adjust from a pencil stream (0°)
to a wide angle fan spray (40°). The
spray can be adjusted by twisting the
nozzle clockwise and/or counter-
clockwise. Also, the high and low
pressure settings can be controlled
by moving the nozzle in and out. See
Operation section.
ENGINE
Refer to the engine manual for loca-
tion and operation of engine controls.
Chemical Hose: Allows cleaners or
cleaning solvents to be mixed with
the pressurized water stream. See
How To Siphon Chemicals/Cleaning
Solvents in Operation section of this
manual.

TERMINOLOGY
NOTE: Become familiar with this ter-
minology before operating.
PSI: Pounds per Square Inch. The
unit of measure for water pressure.
Also used for air pressure, hydraulic
pressure, etc.

11- ENG D25130
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 dan-
gerous level and can damage internal
components of the pump. Any dam-
age 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 will cause damage to
pump.
Thermal Relief Valve:
In an effort to prevent
damage, pumps are
equipped with a ther-
mal 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.
Chemical Injection: Feeds cleaning
agents into the pump to mix with the
pressurized water and help in clean-
ing.
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 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 solu-
tions to surfaces.
Risk of injection or
injury to person. Do
not direct discharge stream toward
persons, unprotected skin, eyes, or
any pets or animals. Serious injury
can occur.
For high pressure operation, pull back
the nozzle of the multi-reg wand as
shown.
Thermal
Relief
Valve
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 gaso-
line engine (RPM). Slow the
engine down and the water pres-
sure will go down with it.
DO NOT attempt to
increase pump
pressure. A higher pressure set-
ting than the factory set pressure
may damage pump.

12- ENG
D25130
The nozzle at the end of the multi-reg
wand can be rotated to change the
high pressure spray pattern from a
narrow jet to a 40º fan shape, as
shown. Markings have been placed
on the nozzle to help you select the
spray pattern.
For low pressure operation, extend
the nozzle of the multi-reg wand as
shown.
