Water Supply
(Cold Water Only)
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 connected
directly to the public drinking water
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.
Use a water filter to avoid potential
damage from dirt in the water
Garden hose must be at least
5/8 inch (16 mm) in diameter.
Flow rate of water supply must not
fall below 2 GPM/gallons per minute
(7.6 L/min).
Flow rate can be determined by run-
ning the water for one minute into an
empty 5-gallon (18.9 liter) container.
The water supply temperature must
not exceed 104°F/40°C.

Never use the pressure washer to
draw in water contaminated with
e.g. paint thinners, gasoline, oil, etc.
Always prevent debris from being
drawn into the unit by using a clean
water source.
Ground Fault Circuit
Interrupter Protection
This pressure washer is provided with
a ground-fault circuit-interrupter
(GFCI) built into the plug of the power-

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.
