Water connection
WARNING
Danger of backflow of contaminated water into the
drinking water network
Health risk
Observe the regulations of your water supply company.
According to applicable regulations, the device must
never be used with the drinking water network without a
system separator. Use a system separator from
KÄRCHER or a system separator as per EN 12729
Type BA. Water that has flowed through a system sep-
arator is classified as undrinkable. Always connect the
system separator to the water supply and never directly
to the water connection on the device.
● See the "Technical data" for the connected loads.
Note
The supply hose is not included in the scope of delivery.
Note
The system separator is not included in the scope of de-
livery.
1. Connect the system separator to the water inlet (e.g.
tap).
2. Connect the inlet hose (minimum length 7.5 m, min-
imum diameter 1") to the water connection of the de-
vice and to the system separator.
3. Open the water inlet.
Suck water from the container
DANGER
Suction of fluids containing solvents or drinking
water
Risk of injury and damage, contamination of drinking
water
Never extract fluids containing solvents such as paint
thinner, petrol, oil or unfiltered water. The seals in the
device are not resistant to solvents. The spray mist of
solvents is highly flammable, explosive and poisonous.
Never extract water from drinking water tanks.
1. Connect the suction hose (diameter at least 1") to
the water connection.
2. Hang the suction hose in an external water source.
Note
Maximum suction height: 0.5 m

Electrical connection
DANGER
Unsuitable electrical extension cables
Electric shock
Only use approved and appropriately marked electrical
extension cables with a sufficient line cross section for
outdoors.
Make sure that the plug and coupling of an extension
cable used are watertight.
Always unroll extension cables completely.
ATTENTION
Exceeding the grid impedance
Electrical shock in the event of a short-circuit
The maximum permissible mains grid impedance at the
electrical connection point (see Technical data) must
not be exceeded.
Contact your electricity supplier in the case of any un-
certainties regarding the mains grid impedance at your
electrical connection point.
● For connected loads, see technical data and type
plate.
● The electrical connection must be carried out by an
electrician and comply with IEC 60364-1.
DANGER
Flammable fluids
Risk of explosion
Do not spray inflammable liquids.
DANGER
Operation without spray lance
Risk of injury
Never operate the device without the spray lance in-
stalled.
Before each use, check that the spray lance is firmly
seated. The screw connection of the spray lance must
be tightened hand tight.
DANGER
High-pressure water stream
Risk of injury
Never fasten the trigger in the actuated position.
Before doing any work on the device, secure the high-
pressure gun by folding out the safety lever and engag-
ing it.
Hold the high-pressure gun and spray lance with both
hands.
ATTENTION
Operation with an empty fuel tank
Destruction of the fuel pump
Never operate the device with an empty fuel tank.
Changing nozzles
1. Switch off the device and operate the high-pressure
gun until the device is depressurized.
2. Secure the high-pressure gun by folding out the
locking catch and engaging it.
