This product must be grounded. If it
should malfunction or breakdown,
grounding provides a path of least resis-
tance for electric current to reduce the
risk of electric shock. This product is
equipped with a cord having an equip-
ment-grounding conductor and a
grounding plug. The plug must be
plugged into an appropriate outlet that is
properly installed and grounded in ac-
cordance with all local codes and ordi-
nances.
DANGER
Improper connection of the equipment-
grounding conductor can result in a risk
of electrocution. Check with a qualified
electrician or service personnel if you
are in doubt as to whether the outlet is
properly grounded. Do not modify the
plug provided with the product - if it will
not fit the outlet, have a proper outlet in-
stalled by a qualified electrician. Do not
use any type of adapter with this prod-
uct.

CAUTION
When connecting the water inlet to the
water supply mains, local regulations of
your water company must be observed.
In some areas the unit must not be con-
nected directly to the public drinking wa-
ter supply. This is to ensure that there is
no feedback of chemicals into the water
supply. Direct connection via a receiver
tank or backflow preventer, 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 13 mm
or 16 mm (1/2 inch or 5/8) inch in di-
ameter.
Flow rate of water supply must not
fall below 7.6 L/min. (2 GPM/gallons
per minute).
Flow rate can be determined by run-
ning the water for one minute into an
empty 20 litre (5-gallon) container.
The water supply temperature must
not exceed 40°C/104°F.
Never use the pressure washer to
draw in water contaminated with sol-
vents, e.g. paint thinners, gasoline,
oil, etc.
Always prevent debris from being
drawn into the unit by using a clean
water source.
