Safety instructions
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
appliance, e.g. safety devices, highpressure 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 corresponding safety provisions must be
observed.
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 authorized customer service or a skilled
electrician.
High-pressure jets can be
dangerous if improperly
used. The jet must not be
directed at persons, animals, live electrical equipment or at the
appliance itself.
The jet must not be directed at other
persons or directed by the user at him/
herself to clean clothing or footwear.
tible 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
dangerous. 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 includes petrol, paint thinner and heating
oil. The spray mist thus generated is
highly inflammable, explosive and poi-
English 3
sonous. Do not use acetone, undiluted
acids and solvents as they are aggressive towards the materials from which
the appliance is made.
몇 Warning
Unsuitable extension cables can be
hazardous. Only use extension cables
outdoors which have been approved for
this purpose and labelled with a sufficient cable cross section:
1 - 10 m: 1,5 mm
10 - 30 m: 2,5 mm
Check the high-pressure hose for dam-
age before every use. Please arrange
for the immediate exchange of a damaged high-pressure hose.
Do not use the appliance when there
are other persons around unless they
are also wearing safety gear.
High-pressure hoses, fixtures and cou-
plings are important for the safety of the
appliance. Only use high-pressure hoses, fixtures and couplings recommended by the manufacturer.
Cleaning operations which produce oily
waste water, e.g. engine washes, underbody washes, may only be carried
out using washing stations equipped
with an oil separator.
Note
The appliance is not intended for use by
young children or infirm persons without
supervision.
Young children should be supervised to
ensure that they do not play with the appliance.
The operator must use the appliance
properly. When working with the appliance, he must consider the local conditions 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 surfaces to avoid damaging paintwork.

Wear protective clothing and safety
goggles to protect against back spray
containing 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 use of other detergents or chemicals may compromise the safety of the
appliance.
Make sure that the power cable or ex-
tension cables are not damaged by running over, pinching, dragging or similar.
Protect 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
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 minimum fuse rating required at the
socket 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 electrical cables from
the cable drum.

Initial start-up
When the appliance is delivered, the HP
hose and trigger gun are not attached, this
prevents buckling. Please mount these before using the appliance for the first time.
Î Push out the safety clip in the trigger
gun using e.g. a small screwdriver.
Î Join HP hose and trigger gun together.
Î Push clip in until it engages and check
that it is securely fastened by pulling on
the HP hose.
Î Remove cable tie and unroll HP hose
Water supply
Water supply from mains
For connection values, see type plate/technical data.
Observe regulations of water supplier.
Î Use a fibre-reinforced hose (not includ-
ed) with a standard coupling: - Minimum
diameter, 1/2 inches (13 mm). - Minimum length, 7.5 m.
Î Screw the coupling unit (supplied) to the
water connection on the appliance.
Î Push the water supply hose onto the
coupling unit, then connect it to the tap.
몇 Caution
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).
According to the applicable regulations, the appliance must never be
used on the drinking water net
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.
Drawing in water from open reservoirs
When fitted with the appropriate accessories, this high-pressure cleaner can draw in
surface water, e.g. from water butts or
ponds (max. suction height 0.5 m).
English 5
Î Use the Kärcher water filter to protect
the HP pump and accessories (special
accessories, order no. 4.730-059). This
filter removes dirt from incoming water.
Î As the standard coupling system is not
suitable for use in suction mode, the
Kärcher suction hose with integrated filter should be used instead (special accessory, order no. 4.440-238) and
suspended inside the water butt.
Î Remove air from appliance before oper-
ation: Switch on the appliance when the
HP hose is not connected and run it until
the water which discharges from the HP
outlet is free of bubbles. Switch off appliance and connect HP hose.
Note: Fill suction hose with water before
use, this will help ventilate the pump of
air.
Start up
Î Screw HP hose on to HP outlet on appli-
ance.
Î Push the appropriate spray lance on to
the trigger gun and fasten it by turning it
to the right through 90°.
Î Open tap.
Î Plug in mains plug.
Î Set main switch to “I/ON”.
Î Press safety catch on the trigger gun to
release it and pull lever.
High pressure operation
몇 Risk 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
firmly.
Spray lance with pressure regulation
Carrying out the most common cleaning
tasks. The work pressure can be stagelessly regulated between "Min" and "Max".
Î Release the lever on the trigger gun.
Î Turn the spray lance to the desired po-
sition.
Spray lance with dirt blaster
For strong contaminations.
Operation with detergent
Note:
Detergent can only be added when the appliance is being operated in low pressure
mode.
All washing brushes supplied by Kärcher
are designed for use with detergents.
Î Use spray lance with pressure regula-
tion (Vario Power).
Î Turn the spray lance to "Mix" position -
low pressure.
DT suction infeed from DT tank
Î During low pressure operation, deter-
gent is automatically drawn in from the
filled detergent tank.
Î Fill the detergent reservoir with, deter-
gent tablet and water or detergent concentrate and water (observe metering
recommendations on the packaging label of the detergent).
Î Dosage happens through the DT meter-
ing regulator.
Recommended Cleaning Method
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.
