WARNING
When using this product basic precau-
tions should always be followed, in-
cluding the following:
To reduce the risk of injury, close
supervision is necessary when a

bleed pressures quickly. Be thor-
oughly familiar with the controls.
Stay alert – watch what you are do-
ing.
Do not operate the product when fa-
tigued or under the influence of al-
cohol or drugs.
Keep operating area clear of all per-
sons.
Do not overreach or stand on unsta-
ble support. Keep good footing and
balance at all times.
Follow the maintenance instruc-
tions specified in the manual.
This product is provided with a
Ground Fault Circuit Interrupter
built into the power cord plug. If re-
placement of the plug or cord is
needed, use only identical replace-
ment parts.
WARNING
Risk of Injection or Injury – Do Not
Direct Discharge Stream At Per-
sons.
High pressure jets can be danger-
ous if misused. The jet must not be
directed at persons, animals, elec-
trical devices, or the unit itself.
Wear safety goggles.
WARNING
Risk Of Explosion – Do not spray
flammable liquids.
Do not use acids, alkaline, solvents,
or any flammable material in this
product. These products can cause
physical injuries to the operator and
irreversible damage to the machine.
CAUTION
Gun Kicks Back – Hold with both
hands.
The Trigger Gun Safety Lock pre-
vents the trigger from accidentally
being engaged. This safety feature
DOES NOT lock trigger in the ON
position.
WARNING – Risk of Electrocu-
tion

the skin. do not point the gun at anyone
or any part of the body. In case of pen-
etration seek medical aid immediately.
This system is capable of producing
12400 kPa /1800 PSI to avoid rupture
and injury, do not operate this pump
with components rated less than
12400 kPa /1800 PSI working pres-
sure (including but not limited to spray
guns, hose and hose connections).
Before servicing, cleaning or removing
any parts, shut off power and relieve
pressure.
This product must be grounded. If it
should malfunction or breakdown,
grounding provides a path of least re-
sistance for electric current to reduce
the risk of electric shock. This product
is equipped with a cord having an
equipment-grounding conductor and a
grounding plug. The plug must be
plugged into an appropriate outlet that
is properly installed and grounded in
accordance with all local codes and or-
dinances.
DANGER
Improper connection of the equipment-
grounding conductor can result in a
risk of electrocution. Check with a qual-
ified electrician or service personnel if
you are in doubt as to whether the out-
let is properly grounded. Do not modify
the plug provided with the product - if it
will not fit the outlet, have a proper out-
let installed by a qualified electrician.
Do not use any type of adapter with this
product.
This pressure washer is provided with
a ground-fault circuit-interrupter (GF-
CI) built into the plug of the power-sup-
ply cord. This device provides
additional protection from the risk of
electric shock. Should replacement of
the plug or cord become necessary,
use only identical replacement parts
that include GFCI protection.
CAUTION
When connecting the water inlet to the
water supply mains, local regulations
of your water company must be ob-
served. In some areas the unit must
not be connected directly to the public
drinking water supply. This is to ensure
that there is no feedback of chemicals
into the water supply. Direct connec-
tion via a receiver tank or backflow pre-
venter, for example, is permitted.
Dirt in the feed water will damage the
unit. To avoid this risk, we recommend
fitting a water filter.
Garden hose must be at least 1/2
inch or 5/8 inch in diameter.
Flow rate of water supply must not
fall below 2 GPM (gallons per min-
ute).
Flow rate can be determined by
running the water for one minute
into an empty 5-gallon container.
The water supply temperature must
not exceed 104°F/40°C.
Never use the pressure washer to
draw in water contaminated with
solvents, e.g. paint thinners, gaso-
line, oil, etc.
Always prevent debris from being
drawn into the unit by using a clean
water source.

WARNING
To avoid serious injury never point
spray nozzle at yourself, other per-
sons or animals.
Always test an inconspicuous area
before cleaning with high pressure.
The Vario Power Spray Wand allows
you to adjust the cleaning pressure.
To clean at maximum pressure, the
wand must be positioned to the high
pressure setting (Max).
For lower pressure turn the wand
collar in the minus (Min) direction.
To apply detergent, the wand must
be positioned to the lower pressure
setting (Mix).
This nozzle features a 0º pencil jet
which rotates 360º for maximum dirt
cutting action, effectively increasing
cleaning performance up to 50%.
This nozzle combines the cleaning
performance of a 0º pencil jet with
the surface coverage of a wide an-
gle nozzle.
Not recommended for soft mate-
rials, siding, painted surfaces,
decks or autos.
Before cleaning any surface an in-
conspicuous area should be
cleaned to test spray pattern and
distance for maximum cleaning re-
sults.

face at low pressure. For best results,
limit your work area to smaller sections
of approximately 25 square feet. Allow
detergent to remain on surface 1-3
minutes. Do not allow detergent to dry
on surface. Rinse at high pressure in a
long sweeping motion keeping the
