SERVICING OF A DOUBLE-
INSULATED PRODUCT
In a double-insulated product, two systems 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 double-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 identical
to the parts they replace. A doubleinsulated product is marked with the words
“DOUBLE INSULATION” or “DOUBLE
INSULATED”. The symbol “ ” may also
be marked on the product.
GROUND FAULT CIRCUIT
INTERRUPTER PROTECTION
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.
WATER SUPPLY
(Cold Water Only)
몇 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 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.
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 13 mm
or 16 mm (1/2 inch or 5/8) inch in di-
ameter.
Flow rate of water supply must not
fall below 7.6 L/min. (2 GPM/gallons
per minute).
Flow rate can be determined by run-
ning the water for one minute into an
empty 20 litre (5-gallon) container.
The water supply temperature must
not exceed 40°C/104°F.
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.

USING THE ACCESSORIES
WARNING
To avoid serious injury never point
spray nozzle at yourself, other persons or animals.
Always test an inconspicuous area
before cleaning with high pressure.
Spray wand
This nozzle features a steady powerful
high pressure spray pattern, for general
cleaning.

WORKING WITH
DETERGENTS
Detergents can only be applied at low
pressure.
STEP 1:
Fill a container with Kärcher deter-
gent. Place the filter end of detergent
siphon tube into the container.
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 materials, siding, painted surfaces,
decks or autos.
Before cleaning any surface an in-
conspicuous area should be cleaned
to test spray pattern and distance for
maximum cleaning results.
STEP 2:
Detach spray wand from the trigger
gun.
A low-pressure jet is generated if no
spray wand is attached to the trigger
gun.
STEP 3:
Turn on the pressure washer (I). Pull
trigger to operate unit. Liquid deter-
gent is drawn into the unit and mixed
with water. Apply detergent to work
area. Do not allow detergent to dry
on surface.

pull trigger to operate unit.
STEP 5:
Cleaning up: Always draw fresh wa-
ter through the detergent tank or si-
phon tube when done to flush any
remaining detergents from the injec-
tion system.

CLEANING TIPS
몇 CAUTION
Before cleaning any surface an in-
conspicuous area should be cleaned
to test spray pattern and distance for
maximum cleaning results.
If painted surfaces are peeling or
chipping, use extreme caution as
pressure washer may remove the
loose paint from the surface.
When using on surfaces which might
come in contact with food, flush surfaces with plenty of drinking water.

Deck Cleaning
(with or without detergent). Pre-rinse
deck and surrounding area with fresh
water. If using detergent, apply to surface at low pressure. For best results,
limit your work area to smaller sections
of approximately 2.3 m² (25 sq. ft.). Allow detergent to remain on surface 1-3
minutes. Do not allow detergent to dry
on surface. Rinse at high pressure in a
long sweeping motion keeping the spray
nozzle approximately 7.5-15 cm (3-6 in.)
from the cleaning surface. Always clean
from top to bottom and from left to right.
When moving on to a new section of the
cleaning surface, be sure to overlap the
previous section to eliminate stop marks
and ensure a more even cleaning result.
House Siding
(with or without detergent). Pre-rinse
cleaning surface with fresh water. If using detergent, apply to surface at low
pressure (for best results, limit your
work area to sections of approximately
1.8 m (6 ft.) and always apply detergent
from bottom to top). Allow detergent 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 remove stubborn dirt.
Rinse at high pressure from top to bottom in an even sweeping motion keeping the spray nozzle approximately
1.8 m (6 ft.) from the cleaning surface.
Cement Patios, Brick and Stone
(with or without detergent). Pre-rinse
cleaning surface with fresh water. If using
detergent or Degreaser, apply to surface
at low pressure. For best results, limit
your work area to smaller sections of approximately 2.3 m² (25 sq. ft.). Allow detergent or Degreaser to remain on
surface 1-3 minutes. Do not allow detergent to dry on surface. Rinse at high
pressure in a sweeping motion keeping
the spray nozzle approximately 7.515 cm (3-6 in.) from the cleaning surface.
Always clean from top to bottom and from
left to right. For removing extremely stubborn stains, use the Dirtblaster ® Nozzle.
Cars, Boats and Motorcycles
(with or without detergent). Pre-rinse
vehicle with fresh water. If using detergent, apply to surface at low pressure.
For best results, clean one side of vehicle at a time and always apply detergent
from bottom to top, do not allow detergent to dry on surface. If needed, use
special wash brush attachment (not included) to remove stubborn dirt. Rinse
at high pressure in a sweeping motion
keeping the spray nozzle approximately
15-20 cm (6-8 in.) from the cleaning surface (distance should increase when
rinsing pin-striping or other sensitive
surfaces). Always clean from top to bot-
English 11
tom and from left to right. For best results, wipe surface dry with a chamois or
soft dry cloth.
Barbecue Grills, Outdoor Power
Equipment and Gardening Tools
(with or without detergent). Pre-rinse
cleaning surface with fresh water. If using detergent or Degreaser, apply detergent at low pressure. Allow detergent to
remain on surface 1-3 minutes. Do not
allow detergent to dry on surface. Rinse
at high pressure keeping the spray nozzle approximately 7.5-15 cm (3-6 in.)
from the cleaning surface. For removing
extremely stubborn dirt, it may be necessary to move the spray nozzle even
closer to the surface for greater dirt cutting action.
