For Your Safety
Before first start-up it is definitely necessary
to read the operating instructions and safety indications Nr. 5.951-949!
Symbols on the machine
High-pressure jets can be dangerous if improperly used. The
jet may not be directed at persons, animals, live electrical equipment or
at the appliance itself.
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.
Proper use
Use the devices exclusively for
– Cleaning using low pressure jet and de-
tergent (for e.g. for cleaning machines,
cars, buildings, tools),
– For cleaning using high pressure jet
without detergent (for e.g. for cleaning
facades, terraces, garden appliances).
For stubborn dirt, we recommend the use of
the dirt blaster as a special accessory.
Safety Devices
Pressure switch
If the lever on the trigger gun is released
the pressure switch turns off the pump, the
high-pressure jet ist stopped. If the lever is
pulled the pump is turned on again.
Overflow valve
The overflow valve prevents the permissible working pressure from being exceeded.
The overflow valve and pressure switch are
set and sealed at the factory. Setting only
by customer service.

Start up
Electrical connection
몇 Warning
The appliance may only be connected to alternating current.
The appliance may only be connected to an
electrical supply which has been installed in
accordance with IEC 60364.
The voltage indicated on the type plate
must correspond to the voltage of the electrical source.
The minimum fuse rating required at the
socket outlet is (see technical specifications).
The appliance should always be connected
to the electrical mains using a plug. It is forbidden to permanently connect the appliance to the power supply. The plug is only
for mains separation.
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.
The plug and coupling of the extension cable used must be watertight.
Use the extension cord that has an adequate cross-section (see "Technical Data")
and unwind it fully from the cable drum.
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:
For connection values, see type plate/technical data.
Water connection
Connection to the water supply
몇 Warning
Observe regulations of water supplier.
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.
For connection values refer to technical
specifications
English 9
Î Connect the supply hose(minimu length
7.5 m, minimum diameter 1/2“) to the

tap).
Note
The supply hose is not included.
Î Open the water supply.
Drawing in water from open reservoirs
Î Screw the suction hose with filter (order
no. 4.440-238.0) to the water connection.
Î Deaerate the appliance:
Unscrew the nozzle.
Switch on the appliance and let it run

Operation
Danger
If the appliance is used in hazardous areas
(e.g. filling stations) the corresponding
safety provisions must be observed.
몇 Warning
Clean engines only at places with corresponding oil separators (environmental
safety).
The jet must not be directed by the user at
him/herself or at other persons to clean
clothing or footwear.
Risk of blocking. Place the nozzles in the
accessory compartment with their joint
pointing upward.
High pressure operation
몇 Warning
Long hours of using the appliance can
cause circulation problems in the hands on
account of vibrations.
It is not possible to specify a generally valid
operation time, since this depends on several factors:
– Proneness to blood circulation deficien-
cies (cold, numb fingers).
– Low ambient temperature. Wear warm
gloves to protect hands.
– A firm grip impedes blood circulation.
– Continuous operation is worse than an
operation interrupted by pauses.
In case of regular, long-term operation of
the device and in case of repeated occur-
rence of the symptoms (e.g. cold, numb fingers) please consult a physician.
Note
The appliance is equipped with a pressure
switch. The motor starts up only when the
lever of the pistol is pulled.
Î Set the appliance switch to "I".
Î Unlock the hand-spray gun and pull the
lever of the gun.
Operation with detergent
몇 Warning
Unsuitable detergents can cause damage
to the appliance and to the object to be
cleaned. Use only those detergents that
have been approved by Kärcher. Observe
the dosage and other instructions provided
with these detergents. For considerate
treatment of the environment use detergent
economically.
Kärcher detergents ensure smooth functioning. Please consult us or ask for our
catalogue or our detergent information
sheets.
Î Take out detergent suck hose.
Î Suspend end of suction hose in a con-
tainer filled with detergent.
Î Replace the high-pressure nozzle with
triple nozzle 4.763-987.0 (not included
