ers.
The scope of delivery of your appliance is il-
lustrated on the packaging. Check the con-
tents of the appliance for completeness
when unpacking.
In the event of missing accessories or any
transport damage, please contact your
dealer.
This high-pressure cleaner is designed for
domestic use only:
–to clean machines, vehicles, buildings,
tools, facades, terraces, garden equip-
ment etc. using a high-pressure water
jet (and detergents if required).
–with accessories, replacement parts
and detergents approved by KÄRCH-
ER. Observe the instructions provided
with these detergents.
Danger
Immediate danger that can cause severe
injury or even death.
몇Warning
Possible hazardous situation that could
lead to severe injury or even death.
Caution
Possible hazardous situation that could
lead to mild injury to persons or damage to
property.
The high pressure jet may not
be directed at persons, ani-
mals, live electrical equipment
or at the appliance itself. Pro-
tect the appliance against
frost.
The packaging material can be recy-
cled. Please do not place the packag-
ing into the ordinary refuse for
disposal, but arrange for the proper
recycling.
Old appliances contain valuable ma-
terials that can be recycled. Please
arrange for the proper recycling of old
appliances. Please dispose your old
appliances using appropriate collec-
tion systems.

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 and mains plug
for damage before every use. If the
power cord is damaged, please arrange
for it to be replaced immediately by an
authorised repair agent or a skilled
electrician.
Check the high pressure hose for dam-
age before every use. Please arrange
for the immediate replacement of a
damaged 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) all of the safety
provisions and operating instructions
detailed in this manual must be ob-
served.
High pressure jets can be dangerous if
improperly used. The jet must not be di-
rected at persons, animals, live electri-
cal 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!
Risk of explosion!
Do not spray flammable liquids.
Never draw in fluids containing solvents
or undiluted acids! This includes petrol,
paint thinner and heating oil. The spray
mist thus generated is highly inflamma-
ble, explosive and poisonous. Do not
use acetone, undiluted acids or sol-
vents as they are damaging to the ma-
terials from which the appliance is
made.
몇Warning
The mains plug and the coupling of an
extension cable must be watertight and
must never lie in water. Moreover, the
coupling may never lie on the ground.
The use of cable reels that ensure that
the sockets are at least 60 mm above
the ground is recommended.
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.
The appliance must not be operated by
children or persons who have not been
instructed accordingly.
The appliance may be used by individu-
als with limited physical, sensory or
cognitive abilities or lack of experience
and knowledge if they are under super-
vision or were instructed regarding the
safe use of the appliance and under-
stand the resulting risks.
Supervise children to prevent them
from playing with the appliance.
Keep packaging film away from children
- risk of suffocation!
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.
Safety instructions

English 5
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.
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.
Caution
In case of extended downtimes, switch
the appliance off at the main switch / ap-
pliance switch or remove the mains
plug.
Do not operate the appliance at temper-
atures below 0 °C.
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.
For safety reasons, we recommend that
you operate the appliance only via an
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.
The high pressure hose is specially con-
structed with reinforced walls to handle wa-
ter pressure up to 11 MPa (1600 psi) - it can
be easily damaged and should be stored
carefully.
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.
Caution
Safety devices protect the user and must
not be modified or bypassed.
The appliance switch prevents unintention-
al operation of the appliance.
This lock locks the lever of the trigger gun
and prevents the inadvertent start of the ap-
pliance.
If the lever on the trigger gun is released
the pressure switch turns off the pump, the
high pressure jet is stopped. If the lever is
pulled the pump is turned on again.
Caution
Create stability for the appliance prior to all
work on or with the appliance to prevent ac-
cidents or damage.
–The stability of the appliance is warrant-
ed when it is placed onto an even sur-
face.

According to the applicable regula-
tions, the appliance must never be
used on the drinking water supply
without a system separator. Use a
suitable system separator manufactured by
KÄRCHER; or, as an alternative, a system
separator as per EN 12729 Type BA. Water
flowing through a system separator is con-
sidered non-drinkable.
Caution
Always connect the system separator to the
water supply, never directly to the appliance!
Note: Impurities in the water can damage
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.

ter connection on the appliance.
Push the water supply hose onto the
coupling unit, then connect it to the wa-
ter supply.
Caution
Dry runs lasting longer than two minutes
lead to damages to the high pressure
pump. If the appliance does not build up
pressure within two minutes, switch it off
and proceed as instructed in the Chapter
"Troubleshooting".
