DANGER
RISK OF INJURY AND
PROPERTY DAMAGE
WHEN
TRANSPORTING OR
STORING
The powerful spray from your pressure washer is capable of causing 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 unit with water supply shutoff without flow of water will result in equipment damage. Operating the pressure
washer with water supply shutoff will void your warranty. You should never run this pressure washer for more than 2
minutes without pulling the trigger to allow cool water to enter the pump and the heated (recirculated) water to exit.
• Fuel or oil can leak or spill and could
result in fire or breathing hazard, serious
injury or death can result. Fuel or oil leaks
will damage carpet, paint or other
surfaces in vehicles or trailers.
5 — ENG
• If pressure washer is equipped with a fuel
shut-off valve, turn the valve to the off
position before transporting to avoid fuel
leaks. If pressure washer is not equipped
with a fuel shut-off valve, drain the fuel from
tank before transporting. Only transport fuel
in an OSHA approved container. Always
place pressure washer on a protective mat
when transporting to protect against damage
to vehicle from leaks. Remove pressure
washer from vehicle immediately upon arrival
at your destination.

GLOSSARY
PSI: Pounds per square inch is a unit of measure for
pressure.
GPM: Gallons Per Minute (Flow Rate)
Cleaning Units: GPM x PSI
Vertical: A vertical pressure washer has the pump
located underneath the engine.
Horizontal: A horizontal pressure washer has the
pump located behind the engine.
Multi-Reg wand/lance: This type of wand/lance is
black and has a spray nozzle which is adjustable
from a pencil stream (0°) to a wide angle fan spray
(60°). The spray can be adjusted by twisting the
nozzle clockwise and/or counterclockwise. Also, the
high and low pressure settings can be controlled by
moving the nozzle in and out. See page 11.
Hi-Low:This type of lance has one chrome tube with
a black knob on the nozzle end. The knob can be
turned clockwise and counterclockwise to control
the high and low pressure settings. It comes with a
¼” NPT, 15° nozzle. To obtain different spray patterns, the nozzle must be removed and replaced with
one of the desired degree. The available patterns are
0°, 25°, and 40°. When replacing nozzles, be sure to
use one of the same flow rating. Be sure to apply
teflon tape to nozzle threads to prevent leaks. See
page 11.
• Check for visible shipping damage. Shipping damage
will cause problems in operation of this unit.
• If you experience any problems and need
assistance, please call us at our toll free number
1-800-888-2468, Ext 2, 8:00 a.m. to 8:00 p.m. E.S.T.

tubes with a handle grip near the gun/lance connection and two nozzles on the end. The handle grip can
be turned clockwise and counter clockwise to control
the high and low pressure settings. It also comes
with a ¼” NPT, 15° high pressure nozzle. To obtain
different spray patterns, the nozzle must be removed
and replace with one of the desired degree. The
available patterns are 0°, 25°, and 40°. NOTE: Be
sure not to remove the chemical nozzle. It is the
nozzle with the larger hole in it. When replacing
nozzles, be sure to use one of the same flow rating.
Be sure to apply teflon tape to nozzle threads to
prevent leaks. See page 11.
Quick Connect: This type of lance is equipped with
a female quick connect coupler on the end. This
allows the user to quickly change out high-pressure
nozzles for different spray patterns and change to the
soap nozzle for low pressure and chemical/soap
applications. See page 12 .
By Pass Mode: During normal operation, a continuous flow of cold water is needed to keep the pressure washer pump operating at a safe temperature. If
the pressure washer is operated without an adequate
water supply, or operated for more than two (2)
minutes without pulling the trigger, the pump will
overheat and cause serious damage. Any damage to
the pump due to these causes will not be covered
under warranty.
