Safety instructions
 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 appliance, e.g. high pressure hoses, trigger 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
 Check the high pressure hose for damage 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 areas (e.g. filling stations) all of the safety
provisions and operating instructions
detailed in this manual must be observed.
 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 high pressure jet must not be directed at other persons or directed by
the user at him/herself to clean clothing
or footwear.
 Never use the appliance to clean objects containing hazardous substances
(e.g. asbestos).
 Vehicle tyres or tyre valves are susceptible 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!
 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 inflammable, explosive and poisonous. Do not
use acetone, undiluted acids or solvents as they are damaging to the materials from which the appliance is
The mains plug and the coupling of an
extension cable must be watertight and
must never lay in the water.
Unsuitable electrical extension cables
can be hazardous. Only use electrical
extension cables outdoors which have
been approved and labelled for this purpose and have an adequate cable
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 couplings are important for the safety of the
appliance. Only use high pressure hoses, fixtures and couplings recommended by the manufacturer.
This appliance is not intended for use
by persons with reduced physical, sensory or mental capabilities.
The appliance must not be operated by
children or persons who have not been
instructed accordingly.
Children should be supervised to prevent them from playing with the appliance.
The operator must use the appliance
correctly. 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.
Keep packaging film away from children
- risk of suffocation!
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.

Protect the power cable from heat, oil,
and sharp edges.
 All current-conducting parts in the working area must be protected against jet
 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
 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, underbody washes, may only be carried
out using washing stations equipped
with an oil separator.
4 English
High pressure hose
The high pressure hose is specially constructed with reinforced walls to handle water pressure up to 14,5 MPa (2100 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.
Safety Devices
Safety devices protect the user and must
not be modified or bypassed.
Power switch
The appliance switch prevents unintentional operation of the appliance.
Lock trigger gun
This lock locks the lever of the trigger gun
and prevents the inadvertent start of the appliance.
Overflow valve with pressure switch
The overflow valve prevents the permissible working pressure from being exceeded.
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.
Prerequisites for the
appliance's stability
Create stability for the appliance prior to all
work on or with the appliance to prevent accidents or damage.
– The stability of the appliance is warranted when it is placed onto an even surface.

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 considered non-drinkable.
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.
Water supply from mains
Observe regulations of water supplier.
For connection values, see type plate/technical data.
