GROUNDING INSTRUCTIONS
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.
GROUND FAULT CIRCUIT IN-
TERRUPTER PROTECTION
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.
WATER SUPPLY
(Cold Water Only)
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.
