(Cold Water Only)
ƽ CAUTION
„ BEFORE SERVICING, CLEANING
OR REMOVING ANY PARTS, SHUT
OFF POWER AND RELIEVE PRES-
SURE.
„ IF CONNECTION IS MADE TO A PO-
TABLE WATER SYSTEM, THE SYS-
TEM SHALL BE PROTECTED
AGAINST BACKFLOW.
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.
GROUND FAULT CIRCUIT
INTERRUPTER PROTECTION
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.
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.
„ 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.
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 dou-
ble-insulated product must be identical

Dirtblaster®
To avoid serious injury never point
spray nozzle at yourself, other per-
sons or animals.
„ This nozzle features a 0º pencil jet
which rotates 360º for maximum dirt
cutting action, effectively increasing
cleaning performance up to 50%.
This nozzle combines the cleaning
performance of a 0º pencil jet with
the surface coverage of a wide angle
nozzle.
Always test an inconspicuous area
before cleaning with high pressure.
Vario Power Spray Wand
„ The Vario Power Spray Wand allows
you to adjust the cleaning pressure.
To clean at maximum pressure, the
wand must be positioned to the high
pressure setting (Max).
Not recommended for soft materi-
als, siding, painted surfaces,
decks or autos.
For reduced pressure turn the wand
collar in the „Min“ direction.
To apply detergent, the wand must
be positioned to the low pressure
setting (Mix).
„ Before cleaning any surface an in-
conspicuous area should be cleaned
to test spray pattern and distance for
maximum cleaning results.
