WARNING!
SERVICING OF A DOUBLE-
INSULATED MACHINE
In a double-insulated machine, two systems
of insulation are provided instead of
grounding. No grounding means are
provided for a double-insulated machine,
nor should grounding means be added to
the machine. Servicing a double-insulated
machine requires extreme care and
knowledge of the system, and should be
done only by qualified service personnel.
Replacement parts for a double-insulated
machine must be identical to the original
parts. A double-insulated machine is
marked with the words “Double Insulation
"or “Double Insulated.” Machine may also
be marked with symbol shown in Figure 1.
WARNING!Do not use pressure
that exceeds the operating
pressure of any of the parts (hoses,
fittings, etc.) in the pressurized system.
Ensure all equipment and accessories
are rated to withstand the maximum
working pressure of the unit.
WARNING!Explosion hazard.
Never spray flammable liquids or use
pressure washer in areas containing
combustible dust, liquids or vapors.
Never operate the machine in a closed
building or in or near an explosive
environment.
WARNING!Do not spray electrical
apparatus and wiring.
• Never disconnect the high pressure
discharge hose from the machine while the
system is pressurized. To depressurize
machine, turn power and water supply off,
then press gun trigger 2~3 times.
• Never permanently engage the trigger
mechanism on the gun.
• Never operate the machine without all
components properly connected to the
machine (handle, gun/wand assembly,
nozzle, etc.).
WARNING! Equipment damage.
• ALWAYS turn water supply “ON” before
turning pressure washer “ON.” Running
the pump dry causes serious damage.
• Do not operate the pressure washer with
the inlet water screen removed. Keep
screen clear of debris and sediment.
• NEVER operate pressure washer with
broken or missing parts. Check equipment
regularly and repair or replace worn or
damaged parts immediately.

•Use only the nozzle supplied with this
machine.
•Never leave the wand unattended while
the machine is running.
•Never attempt to alter factory settings.
Altering factory settings could damage the
unit and will void the warranty.
•Always hold the gun and wand firmly
when starting and operating the machine.
•NEVER allow the unit to run with the
trigger released (off) for more than one (1)
minute. The resulting heat buildup will
damage the pump.
•The pressure washer is not designed to
pump hot water. NEVER connect it to a hot
water supply as it will significantly reduce
the life of the pump.
•NEVER store the pressure washer
outdoors or where it could freeze. The
pump will be seriously damaged.
•Release the trigger when changing from
high to low pressure modes. Failure to do
so could result in damage.
•Be aware of the recoil caused by the
water jet when the machine is switched on.
CAUTION: Keep the hose away from
sharp objects. Bursting hoses may cause
injury. Examine the hose regularly and
replace it if damaged.
Do not attempt to mend a damaged
hose.
EXTENSION CABLES
The use of an extension cable is not
recommended. Use only extension cables
intended for outdoor use. These are
identified by the mark “Acceptable for
use with outdoor machines; store indoors
while not in use.” Use only extension cables
having an electrical rating equal to or more
than the rating of the machine. Do not use
damaged extension cables.Examine
extension cable before using and replace it if
damaged. Do not abuse extension cable.
Do not pull on the cable to disconnect. Keep
cable away from heat and sharp edges.
Always disconnect cable from receptacle
before disconnecting machine from
extension cable.
DANGER!Failure to follow these
instructions can result in serious injury,
including death.
