SAVE THESE INSTRUCTIONS
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
double-insulated product must be iden-
tical to the parts they replace. A double-
insulated product is marked with the
words “DOUBLE INSULATION” or
“DOUBLE INSULATED”. The symbol
“” may also be marked on the product.
IMPORTANT SAFETY INSTRUCTIONS

INSULATED PRODUCT
English 5
This product 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.
Contact Kärcher Customer Support.
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.
Screwdriver, small size (not supplied)
for connecting high pressure hose and
trigger gun.
Î STEP 1:
Insert wheels into the side holes of
the unit.
Î STEP 2:
Attach the high pressure hose to the
trigger gun.
A Pull out the locking slide from the
right side of the trigger gun handle.

WARNING
To avoid serious injury never point
spray nozzle at yourself, other per-
sons or animals.
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).
For lower pressure turn the wand
collar in the minus (Min) direction.
To apply detergent, the wand
must be positioned to the lower
pressure setting (Min).
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.
Not recommended for soft materi-
als, siding, painted surfaces,
decks or autos.

results, limit your work area to smaller
sections of approximately 25 square
feet. Allow Deck Wash to remain on sur-
face 1-3 minutes. Do not allow deter-
gent to dry on surface. Rinse at high
pressure in a long sweeping motion
keeping the spray nozzle approximately
3-6 inches from the cleaning surface.

new section of the cleaning surface, be
sure to overlap the previous section to
eliminate stop marks and ensure a more
even cleaning result.

proximately 6 feet and always apply de-
tergent from bottom to top). Allow
Pressure Wash to remain on surface 1-
3 minutes. Do not allow detergent to dry
on surface, if surface appears to be
drying, simply wet down surface with
fresh water. If needed, use special wash
brush attachment (not included) to re-
move stubborn dirt. Rinse at high pres-
