Danger
Never touch the mains plug and the 
socket with wet hands.
The appliance must not be used if the 
power cord or important parts of the ap-
pliance, e.g. high-pressure hoses, trig-
ger gun or safety devices are damaged.
Check the power cord with mains plug 
for damage before every use. If the 
power cord is damaged, please arrange 
immediately for the exchange by an au-
thorized customer service or a skilled 
electrician.
Check the high-pressure hose for dam-
age before every use. Please arrange 
for the immediate exchange of a dam-
aged high-pressure hose.
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 corre-
sponding safety provisions must be 
observed.
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 high-pressure jet must not be di-
rected at other persons or directed by 
the user at him/herself to clean clothing 
or footwear.
Never use the appliance to clean ob-
jects containing hazardous substances 
(e.g. asbestos).
Vehicle tyres or tyre valves are suscep-
tible to damage from the high-pressure 
jet and may burst. The first indication of 
this is a discolouration of the tyre. Dam-
aged vehicle tyres/tyre valves are high-
ly dangerous. Ensure that a distance of 
at least 30 cm is observed when clean-
ing 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
The mains plug and the coupling of an 
extension cable must be watertight and 
must never lay in the water.
Unsuitable extension cables can be 
hazardous. Only use extension cables 
outdoors which have been approved for 
this purpose and labelled with a suffi-
cient cable cross-section: 
1 - 10 m: 1.5 mm2; 10 - 30 m: 2.5 mm2   
Always fully unroll electrical cables from 
the cable drum.
High-pressure hoses, fixtures and cou-
plings are important for the safety of the 
appliance. Only use high-pressure hos-
es, fixtures and couplings recommend-
ed by the manufacturer.
This device is not intended for use by 
persons (including children) with re-
duced physical, sensory or mental abil-
ities or lacking experience and/or 
knowledge, unless they are supervised 
by a person responsible for their safety 
or are instructed by these persons on 
the use of the device. Children should 
be supervised, to ensure  that they do 
not play with the device.
The operator must use the appliance 
correctly. 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.
Do not use the appliance when there 
are other persons around unless they 
are also wearing safety equipment. 
Wear protective clothing and safety 
goggles to protect against splash back 
containing water or dirt.
Safety instructions

4 English
Caution
Observe a distance of at least 30 cm 
when using the jet to clean painted sur-
faces to avoid damaging paintwork.
Never leave the appliance unattended 
when it is in operation.
Make sure that the power cable or ex-
tension cables are not damaged by run-
ning over, pinching, dragging or similar. 
Protect the power cable from heat, oil, 
and sharp edges.
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 
installed in accordance with IEC 60364.
The appliance may only be connected 
to alternating current. The voltage must 
correspond with the type plate on the 
appliance.
The maximum tolerable mains imped-
ance at the electrical contact point (see 
Technical Data) must not be exceeded.
For safety reasons, we recommend that 
you operate the appliance only via a 
earth-leakage circuit breaker (max. 
30 mA).
Cleaning operations which produce oily 
waste water, e.g. engine washes, un-
derbody washes, may only be carried 
out using washing stations equipped 
with an oil separator.
This appliance was designed to be 
used with detergents which are sup-
plied or recommended by the manufac-
turer. The use of other detergents or 
chemicals may compromise the safety 
of the appliance.
When unpacking the product, make sure 
that no accessories are missing and that 
none of the package contents have been 
damaged. If you detect any transport dam-
ages please contact your dealer.

the high-pressure pump and accessories. 
For protection, the use of the KÄRCHER 
water filter (optional accessory, order no. 
4.730-059) is recommended.
Observe regulations of water supplier.
For connection values, see type plate/tech-
nical data.

coupling unit, then connect it to the tap.
This high-pressure cleaner is suited to work 
with the KÄRCHER suction hose with back-
flow valve (Optional accessory, order no. 
4.440-238) to draw in surface water, e.g. 
from water butts or ponds (see specifica-
tions for max. suction height).
