PONENTS RATED LESS THAN 1600
PSI WORKING PRESSURE (INCLUD-
ING BUT NOT LIMITED TO SPRAY
GUNS, HOSE AND HOSE CONNEC-
TIONS).

AGAINST BACKFLOW.
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 dou-
ble-insulated product must be identical
to the parts they replace. A doubleinsu-
lated product is marked with the words
“DOUBLE INSULATION” or “DOUBLE
INSULATED”. The symbol “ ” may also
be marked on the product.
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.

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.
