Description of the Appliance

4 English
Danger
Never touch the mains plug and the
socket with wet hands.
The appliance must not be used if the
power cable or important parts of the ap-
pliance, e.g. safety devices, high-pres-
sure hoses, spray guns, are damaged.
The appliance may not be used in areas
where a risk of explosion is present.
If the appliance is used in hazardous ar-
eas (e.g. filling stations) the correspond-
ing safety provisions must be observed.
Check the power cord with mains plug
for damage before every use. If the pow-
er cord is damaged, please arrange im-
mediately for the exchange by an
authorized customer service or a skilled
electrician.
High-pressure jets can be
dangerous if improperly
used. The jet must not be
directed at persons, ani-
mals, live electrical equipment or at the
appliance itself.
The jet must not be directed at other per-
sons or directed by the user at him/her-
self to clean clothing or footwear.
Never use the appliance to clean objects
containing hazardous substances (e.g.
asbestos).
Vehicle tyres or tyre valves are suscepti-
ble to damage from the high-pressure jet
and may burst. The first indication of this
is a discolouration of the tyre. Damaged
vehicle tyres/tyre valves are highly dan-
gerous. Ensure that a distance of at least
30 cm is observed when cleaning with
the jet!
Never draw in fluids containing solvents
or undiluted acids and solvents! This in-
cludes petrol, paint thinner and heating
oil. The spray mist thus generated is
highly inflammable, explosive and poi-
sonous. Do not use acetone, undiluted
acids and solvents as they are aggres-
sive towards the materials from which
the appliance is made.
몇Warning
Check the high-pressure hose for dam-
age before every use. Please arrange for
the immediate exchange of a damaged
high-pressure hose.
High-pressure hoses, fixtures and cou-
plings are important for the safety of the
appliance. Only use high-pressure hos-
es, fixtures and couplings recommended
by the manufacturer.
This appliance was designed to be used
with detergents which are supplied or
recommended by the manufacturer. The
use of other detergents or chemicals
may compromise the safety of the appli-
ance.
Unsuitable extension cables can be haz-
ardous. Only use extension cables out-
doors which have been approved for this
purpose and labelled with a sufficient ca-
ble cross section:
1 - 10 m: 1,5 mm2; 10 - 30 m: 2,5 mm2
Note
The appliance must not be operated by
children or persons who have not been
instructed accordingly.
The operator must use the appliance
properly. When working with the appli-
ance, he must consider the local condi-
tions and pay due care and attention to
other persons, in particular children, who
are nearby.
Observe a distance of at least 30 cm
when using the jet to clean painted sur-
faces to avoid damaging paintwork.
Cleaning operations which produce oily
waste water, e.g. engine washes, under-
body washes, may only be carried out
using washing stations equipped with an
oil separator.
Wear protective clothing and safety gog-
gles to protect against back spray con-
taining water or dirt.
Safety instructions

English 5
Never leave the appliance unattended
when it is in operation.
Make sure that the power cable or exten-
sion cables are not damaged by running
over, pinching, dragging or similar. Pro-
tect the power cable from heat, oil, and
sharp edges.
The connection between the power ca-
ble and extension cable must not lie in
water.
All current-conducting parts in the work-
ing area must be protected against jet
water.
The appliance may only be connected to
an electrical supply which has been in-
stalled in accordance with IEC 60364.
The appliance may only be connected to
alternating current. The voltage must
correspond with the type plate on the ap-
pliance.
The minimum fuse rating required at the
socket outlet is 13 A (slow-blow).
To avoid accidents due to electrical
faults we recommend the use of sockets
with a line-side current-limiting circuit
breaker (max. 30 mA nominal tripping
current).
The plug and coupling of the extension
cable used must be watertight.
Always fully unroll electrical cables from
the cable drum.
Safety devices serve to protect the user and
must not be rendered inoperational or their
functions bypassed.
The switch prevents unintented starting of
the appliance. Stop the appliance during
breaks or after operation.
The safety catch on the trigger gun prevents
the appliance from being switched on unin-
tentionally.
The high pressure hose is specially con-
structed with reinforced walls to handle wa-
ter pressure up to 11 MPa (1600 psi) - it is
easily damaged and should be stored care-
fully.
Do not kink.
Do not drive vehicles over the hose.
Do not expose the hose to sharp edges
or corners.
Misuse will lead to ballooning or premature
failure and will invalidate warranty.

For connection values, see type plate/tech-
nical data.
Observe regulations of water supplier.
ÎUse a fibre-reinforced hose (not includ-
ed) with a standard coupling: - Minimum
diameter, 1/2 inches (13 mm). - Mini-
mum length, 7.5 m.
ÎScrew the coupling unit (supplied) to the
water connection on the appliance.
ÎPush the water supply hose onto the
coupling unit, then connect it to the tap.
몇Caution
Never operate the high-pressure cleaner
when the tap is turned off as dry running will
damage the High pressure pump.
If the water supply is not clean, the Kärcher
water filter must be used (special accessory
- order No. 4.730-059).
According to the applicable regula-
tions, the appliance must never be
used on the drinking water net with-
out a system separator. Use a suit-
able system separator manufactured by
Kärcher; or, as an alternative, a system sep-
arator as per EN 12729 Type BA.

ance.
ÎPush the appropriate spray lance on to
the trigger gun and fasten it by turning it
to the right through 90°.
ÎOpen tap.
ÎPlug in mains plug.
ÎSet main switch to “I/ON”.
ÎPress safety catch on the trigger gun to
release it and pull lever.
몇Risk of injury
The trigger gun is subjected to a recoil force
when the water jet is discharged. Make sure
that you have a firm footing and are also
holding the trigger gun and spray lance firm-
ly.
ÎFor normal cleaning tasks.
Operation with detergents not possible
For strong contaminations.
Operation with detergents not possible
Note:
Detergent can only be added when the ap-
pliance is being operated in low pressure
mode.

hose in a container with Detergent solu-
tion.
1 Spray a small dose of the detergent on
the dry surface, and allow it to react
(make sure the detergent does not dry
up).
2 Wash off the loosened dirt using the
high-pressure jet.
To ensure a trouble-free operation of the ap-
pliance and to match the individual cleaning
task, we recommend our Kärcher detergent
and maintenance agents. Please ask for our
advice, or request information on the prod-
ucts.
