risk of electric shock. This product is
equipped with a cord having an equip-
ment-grounding conductor and a groun-
ding plug. The plug must be plugged
into an appropriate outlet that is proper-
ly installed and grounded in accordance
with all local codes and ordinances.

if subject to misuse. The jet must not
be directed at persons, animals,
electrical devices, or the machine
itself.
ƽ DANGER
Improper connection of the equipment-

Ground Fault Circuit Interrupter
(GFCI) Protection
This product is supplied with a Ground
Fault Circuit Interrupter (GFCI) built into
the power cord plug. This device provi-
des additional protection from the risk of
electric shock. If power is interrupted in
the line, the GFCI will automatically re-
close the circuit to the load after power
is restored. Depending on the GFCI mo-
del, it may be necessary to manually
operate the reset button to restore po-
wer to the GFCI load circuit. If replace-
ment of the plug or cord is needed use
identical replacement parts.
WATER SUPPLY (Cold Water Only)
ƽ CAUTION
Dirt in the feed water will damage the
unit. To avoid this risk, we recommend
fitting a water filter.
! Water hose must be at least 5/8 inch
in diameter.
! Flow rate of water supply must not
fall below 2 GPM (gallons per minu-
te).
! 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.
