Description of the Appliance

English 4
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. 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 improp-
erly used. The jet may
not be directed at per-
sons, animals, 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
!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
!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.
!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.
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.
!Wear protective clothing and safety gog-
gles to protect against back spray con-
taining water or dirt.
!Never leave the appliance unattended
when it is in operation.
!This appliance was designed to be used
with detergents which are supplied or
recommended by the manufacturer. The
Safety instructions

5 English
use of other detergents or chemicals
may compromise the safety of the appli-
ance or cause appliance damage.
!Make sure that the power cord or exten-
sion cables are not damaged by running
over, pinching, dragging or similar. Pro-
tect the power cords from heat, oil, and
sharp edges.
!The connection between the power cord
and extension cable must not lie in wa-
ter.
!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
sokket outlet is 10 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 the extension cable
from the cable drum.
Safety devices prevent injury and may not
be modified or bypassed.
The switch prevents unintented starting of
the appliance. Stop the appliance during
breaks or after operation.
The safety catch on the handgun prevents
the appliance from being switched on unin-
tentionally.
"Remove the coupling element from the
lower packaging unit and mount it.
"Remove both bearing wheels from the
lower packaging units.
"Insert the bearing wheels into the axle
box and lock them.
"Mount HP hose clip to HP hose.
"Push out the safety clip in the handgun
using e.g. a small screwdriver.
"Join HP hose and handgun together.
"Push clip in until it engages and check
that it is securely fastened by pulling on
the HP hose.
For connection values, see type plate/tech-
nical data.
Observe regulations of water supplier.
"Use a fibre-reinforced hose (not includ-
ed) with a standard coupling: - Minimum
diameter, 1/2 inches (13 mm). - Mini-
mum length, 7.5 m.
"Screw the coupling unit (supplied) to the
water connection on the appliance.
"Push 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 HP pump.
If the water supply is not clean, the Kärcher
water filter must be used (special accessory
- order No. 4.730-059).
When fitted with the appropriate accesso-
ries, this high-pressure cleaner can draw in
surface water, e.g. from water butts or ponds
(max. suction height 0.5 m).
"As the standard coupling system is not
suitable for use in suction mode, the
Kärcher suction hose with integrated fil-

suspended inside the water butt.
"Use the Kärcher water filter to protect the
HP pump and accessories (special ac-
cessories, order no. 4.730-059). This fil-
ter removes dirt from incoming water.
"Appliance ventilation: Switch on the ap-
pliance without connection the HP hose
