ings and instructions may result in electric shock, fire and/or serious injury.
SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE
When using this prod-
should be followed, including the following:
uct, basic precautions
Work area
Do not operate pressure washers in explosive atmospheres, such as in the presence
of flammable liquids, gases or dust. Pres-
sure washer create sparks which may ignite
the dust or fumes.
Keep children and bystanders away while
operating a pressure washer. Distractions
can cause you to lose control.
Store idle pressure washer out of reach
of children and other untrained persons.
Tools are dangerous in the hands of untrained
users.

comply with ANSI Z87.1 and use personal
protective equipment. Protective equipment
such as dust mask, non-skid safety shoes,
hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
Prevent unintentional starting. Ensure the
switch is in the OFF position before connecting to power source, picking up or carrying the pressure washer. Carrying pres-
sure washers with your finger on the switch
or energizing pressure washers that have the
switch ON invites accidents.
Watch your balance and footing while using your power washer. Surfaces become
slippery when wet and are extra slippery when
using a detergent or cleaner.
Do not operate the equipment while barefoot or when wearing sandals or similar
lightweight footwear. Wear protective foot-
wear that will protect your feet and improve
your footing on slippery surfaces.
Do not overreach. Keep proper footing and
balance at all times. This enables better con-
trol of the pressure washer in unexpected situations.
Materials containing asbestos and other
materials which contain substances which

are hazardous to your health must not be
sprayed. Your risk from these exposures var-
ies, depending on how often you do this type
of work. To reduce your exposure to these
substances: work in a well ventilated area,
and work with approved safety equipment,
such as masks that are specifically designed
to filter out microscopic particles.
“Stay alert”. Do not allow familiarity gained
from frequent use of your pressure washer
to become commonplace. Always remem-
ber that a careless fraction of a second is sufficient to inflict severe injury.
Use only accessories that are recommended by the manufacturer for your model. Ac-
cessories that may be suitable for one pressure washer, may become hazardous when
used on another pressure washer.
Electrical safety
Pressure washer plugs must match the
outlet. Never modify the plug in any way.
Unmodified plugs and matching outlets will
reduce risk of electric shock.
Avoid body contact with earthed or
grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an
increased risk of electric shock if your body is
earthed or grounded.
Do not abuse the cord. Never use the cord
for carrying, pulling or unplugging the
pressure washer. Keep cord away from
heat, oil, sharp edges or moving parts.
Damaged or entangled cords increase the risk
of electric shock.
This product is provided with a ground
fault circuit interrupter (GFCI) built into the
power cord plug. If replacement of the plug
or cord is needed, use only identical replacement parts.
• GFCI does not protect against electrical
shock due to contact with both circuit conductors or a fault in any wiring supplying
this device.
• Test GFCI before each use. Do not use
pressure washer and have it serviced to
correct malfunction if it fails the GFCI test.
Pressure washer use and care
Do not use the pressure washer if the
switch does not turn it ON and OFF. Any
pressure washer that cannot be controlled
with the switch may be dangerous and must
be repaired.
Disconnect the plug from the power source
before making any adjustments, changing
accessories, or storing pressure washers.
Such preventive safety measures reduce the
risk of starting the pressure washer accidentally.
Store idle pressure washers out of the
reach of children and do not allow persons
unfamiliar with the pressure washer or
these instructions to operate the pressure
washer. Pressure washers are dangerous in
the hands of untrained users.
Follow the maintenance instructions specified in the manual and maintain pressure
washer. Check for misalignment or binding
of moving parts, breakage of parts and any
other condition that may affect the pressure washer’s operation. If damaged, have
the pressure washer repaired before use.
Many accidents are caused by poorly maintained pressure washers.
Use the pressure washer and accessories
in accordance with these instructions, taking into account the working conditions
and the work to be performed. Use of the
pressure washer for operations different from
those intended could result in a hazardous
situation.
Hold the trigger handle and lance securely
with both hands (one hand to pull the trigger and the other to stabilize the trigger
handle/lance assembly). Expect the trigger
handle to move when the trigger is pulled
due to reaction forces. Failure to do so could
cause loss of control and injury to yourself and
others.
Do not use acids, alkalis, solvents, flammable material, bleaches, or industrial grade
solutions in this product. These products
can cause physical injuries to the operator
and irreversible damage to the machine. The
sprayed vapor is highly flammable, explosive
and toxic.
ONLY use water below 40° C.
Never spray close to the surface to be
cleaned. The high pressure water jet can
damage the surface.

trigger on the trigger handle to relieve
stored pressure in the high pressure hose.
Failure to do so could result in serious personal injury.
All current-conducting components in the
working area must be protected against
splashed water. The addition of water in-
creases the risk of electric shock.
Do not alter or misuse pressure washer.
Any alteration or modification is a misuse and
may result in serious personal injury.
Water Connection
Comply with the regulations of your water
supply company.
All connecting hoses must have properly
sealed joints. Water leaks can create addi-
tional electrical hazards.
Make sure that the supply hose is at least
1/2” in diameter and is reinforced.
