GROUND FAULT CIRCUIT
INTERRUPTER PROTECTION
This pressure washer is provided with a
ground-fault circuit-interrupter (GFCI)
built into the plug of the power-supply
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.
SERVICING OF A DOUBLE-
INSULATED PRODUCT
In a double-insulated product, two sys-
tems of insulation are provided instead
of grounding. No grounding means is
provided on a double-insulated product,
nor should a means for grounding be
added to the product. Servicing a dou-
ble-insulated product requires extreme
care and knowledge of the system, and
should be done only by qualified service
personnel. Replacement parts for a
double-insulated product must be iden-
tical to the parts they replace. A double-
insulated product is marked with the
words "DOUBLE INSULATION" or
"DOUBLE INSULATED". The symbol
" " may also be marked on the product.
WATER SUPPLY
(Cold Water Only)
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 1/2
inch or 5/8 inch in diameter.
Flow rate of water supply must not
fall below 2 GPM (gallons per
minute).
Flow rate can be determined by run-
ning 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 sol-
vents, e.g. paint thinners, gasoline,
oil, etc.
Always prevent debris from being
drawn into the unit by using a clean
water source.
