Safety instructions
 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 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) the corresponding safety provisions must be
 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 and solvents! This includes petrol, paint thinner and heating
4 English
oil. The spray mist thus generated is
highly inflammable, explosive and poisonous. Do not use acetone, undiluted
acids and solvents as they are damaging to the materials from which the appliance is made.
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 sufficient 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 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.
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.
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.
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.
 In case of extended downtimes, switch
the appliance off at the main switch / appliance switch or remove the mains
 Do not operate the appliance at temperatures below 0 °C.
 Observe a distance of at least 30 cm
when using the jet to clean painted surfaces to avoid damaging paintwork.
 Never leave the appliance unattended
when it is in operation.
 Make sure that the power cable or extension cables are not damaged by running over, pinching, dragging or similar.
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 a
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.
High pressure hose
The high pressure hose is specially constructed with reinforced walls to handle water pressure up to 11 MPa (1600 psi) - it can
be easily damaged and should be stored
 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
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
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.

Water supply
According to the applicable regulations, 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 considered non-drinkable.
Always connect the system separator to the
water supply, never directly to the appliance!
Note: Impurities in the water can damage
8 English
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.

included) with a standard coupling.
(Minimum diameter 1/2 inch (13 mm),
minimum length 7.5 m).
 Screw the coupling element to the water connection on the appliance.
 Push the water supply hose onto the
coupling unit, then connect it to the water supply.
Start up
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
 Connect the high pressure hose to the
high pressure connection of the appliance.
 Push the spray lance into the trigger
gun and fasten it by turning it through
 Completely open the water tap.

Suitable for use with detergents.
The rotating washing brush is ideally suited
for the cleaning of vehicles.
Please make sure that the washing brush is
free from dirt or other particles. Otherwise,
it may damage the paint work.
Detergent Foamer
Ideal for applications which require a thick
foam. Simply fill the resevoir cup with liquid
pressure washer detergent to generate a foam
spray. Connects directly to the trigger gun.
Vario joint
Infinitely adjustable up to 180°, for cleaning
of difficult-to-reach areas.
 Attach the vario joint between trigger
gun and accessory.
