Filling up system care
Note
A test container of system care is included in the scope
of delivery.
● System care is a highly effective agent for prevent-
ing calcification of the pump when operating with
calcareous tap water. This is drip-fed dosed into the
float tank.
● The dosage is set to medium water hardness at the
factory.
1. Fill up the system care.
Refuelling
DANGER
Unsuitable fuel
Risk of explosion
Only use diesel fuel or light heating oil. Unsuitable fuels,
such as petrol, must not be used.
ATTENTION
Operation with an empty fuel tank
Destruction of the fuel pump
Never operate the device with an empty fuel tank.
1. Open the tank cap.
2. Refill the fuel.
3. Close the tank cap.
4. Wipe up the spilt fuel.
Refilling detergent
DANGER
Unsuitable detergents
Risk of injury
Use only KÄRCHER products.
Never fill with solvents (e.g. petrol, acetone, thinners).
Avoid contact with eyes and skin.
Observe the safety and handling instructions of the de-
tergent manufacturer.
Note
Kärcher offers an individual range of cleaning and care
products. Your dealer will be happy to advise you.
1. Fill with detergent.
Water connection
● See the "Technical data" for the connected loads.
Note
The supply hose is not included in the scope of delivery.
1. Connect the supply hose (minimum length 7.5 m,
minimum diameter 3/4") to the water connection of
the device and to the water inlet (e.g. tap) using the
water connection adapter.
2. Open the water inlet.
Suctioning 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.
If the device is to draw water from an external container,
the following modification is required:
1. Open the filling hole for system care.

3. Remove the water connection on the fine filter.
4. Unscrew the fine filter on the pump head.
5. Remove the system care container.
Illustration J
6. Unscrew the upper supply hose to the float tank.
7. Connect the upper supply hose to the pump head.
Illustration K
8. Plug the flushing line of the detergent dosing valve
onto the blind plug.
9. Connect the suction hose (diameter at least 3/4")
with filter (accessory) to the water connection.
10. Hang the suction hose in an external water source.
Note
Maximum suction height: 0.5 m
11. Until the pump draws in water: Set the pressure/
quantity regulator of the pump unit to the maximum
value and close the detergent dosing valve.
12. Reinstall in the in the reverse order. Make sure that
the solenoid valve cable is not pinched on the sys-
tem care container.
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 jet
Danger of injury
Never fasten the trigger and safety lever in the actuated
position.
Do not use the high-pressure gun when the safety lever
is damaged.
