This product is supplied with a Ground
Fault Circuit Interrupter (GFCI) built into
the power cord plug. This device pro-
vides 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 pow-
er is restored. Depending on the GFCI
model, it may be necessary to manually
operate the reset button to restore pow-
er to the GFCI load circuit. If replace-
ment of the plug or cord is needed use
identical replacement parts.
ƽ 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 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.
