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
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 par ts. Check equipment
regularly and repair or replace worn or
damaged parts immediately.

• Use only the nozzle supplied with this
machine

• Never attempt to alter factory settings.
Altering factory settings could damage the
unit and will void the warranty.

• Always hold 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. Resulting heat buildup will
damage pump.

• Pressure washer is not supposed 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 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 switc hed on.

CAUTION: Keep hose away from sharp
objects. Bursting hoses may cause injury.
Examine hose regularly and replace it if
damaged.

Do not attempt to mend a damaged hose.

EXTENSION CORDS

The use of an extension cord is not
recommended. Use only extension cords
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 cords
having an electrical rating equal to or more
than the rating of the machine.

Do not use damaged extension cords.

Examine extension cord before using
and replace it if damaged. Do not abuse
extension cord. Do not pull on the cord to
disconnect. Keep cord away from heat
and sharp edges.

Always disconnect cord from receptacle
before disconnecting machine from
extension cord.

DANGER! Failure to follow these
instructions can result in serious injury,
including death.

WARNING! To reduce the risk of
electrocution, keep all connections dry
and off the ground. Do not touch plug
with wet hands.

Machines shall not be used by children.
Children should be supervised to ensure
that they do not play with the machine.

This machine is not intended for use by
persons (including children) with
reduced physical, sensory or mental
capabilities, or lack of experience and
knowledge.

WARNING! This machine has been
designed for use with the cleaning agent
supplied or recommended by the
manufacturer. The use of other cleaning
agents or chemicals may adversely
affect the safety of the machine.

WARNING! Recommend the operator to
wear ear protectors.

WARNING! High pressure jets can be
dangerous if subject to misuse. The jet
must not be directed at persons, live
electrical equipment or the machine
itself.

WARNING! Do not use the machine
within range of persons unless they wear
protective clothing.

WARNING! Do not direct the jet against
yourself or others in order to clean
clothes or foot-wear.

WARNING! Risk of explosion. Do not
spray flammable liquids.

WARNING! High pressure cleaners shall
not be used by children or untrained
personnel.

WARNING! High pressure hoses, fittings
and couplings are important for the
safety of the machine. Use only hosed,
fittings and couplings recommended by
the manufacturer.

WARNING! To ensure machine safety,
use only original spare parts from the
manufacturer or approved by the
manufacturer.

WARNING! Water that has flown
through backflow preventers is
considered to the non-potable.

WARNING! The machine shall be
disconnected from its power source by
removing the plug from the socket-outlet
during cleaning or maintenance and
when replacing the machine to another
function.

WARNING! Do not use the machine if a
supply cord or important parts of the
machine are damaged, e.g. safety
devices, high pressure hoses, trigger
gun.

WARNING! If an extension cord is used,
the plug and socket must be of watertight
construction.

WARNING! Inadequate extension cords
can be dangerous. If an extension cord
is used, it shall be suitable for outdoor
use, and the connection has to be kept
dry and off the ground. It is
recommended that this is accomplished
by means of a cord reel which keeps the
socket at least 60mm above the ground.

WARNING! In order to avoid a hazard
due to inadvertent resetting of the
thermal cut-out, this appliance must not
be supplied through an external
switching device, such as a timer, or
connected to a circuit that is regularly
switched on and off by the utility.
