General notes
Read the original instructions before us-
ing the device for the first time and act in
accordance with it. Keep this document
for future reference or for future owners.
● If the operating instructions and safety instructions
are not observed, the device can be damaged and
dangers could arise for users and other persons.
● Notify the dealer immediately in the case of shipping
damage.
● Check the package contents when unpacking for
missing accessories or for damage.
Environmental protection
The packing materials can be recycled. Please
dispose of packaging in accordance with the en-
vironmental regulations.
Electrical and electronic devices contain valua-
ble, recyclable materials and often components
such as batteries, rechargeable batteries or oil,
which - if handled or disposed of incorrectly - can
pose a potential danger to human health and the envi-
ronment. However, these components are required for
the correct operation of the device. Devices marked by
this symbol are not allowed to be disposed of together
with the household rubbish.

Intended use
● The HKF 30/14-E interior cleaner is a spray unit for
cleaning bung containers according to DIN, as well
as other containers and barrels.
● The cleaning head is brought into the container
through an opening with a minimum diameter of 65
mm.
● A separate high-pressure pump is connected to the
interior cleaner using a high-pressure hose.
● Operation outside of closed containers, operation at
higher pressures and higher temperatures than
those specified in the technical data is regarded as
improper use.
● The device may only be operated with the following
cleaning fluids:
–
Water
–
Fully desalted water
–
Water with alkaline detergent (max. 0-2%)
–
Water with acidic detergent (max. 0-1%)
Note
Only KÄRCHER detergents may be used.
● The device may not be operated in explosive envi-
ronments.
● The device must not be operated with explosive and
flammable substances!
Note
Do not allow waste water containing mineral oil to pen-
etrate soil, waterways or the sewage system.
Function
● The interior cleaner consists of the drive part, the
carrier tube and the cleaning head. The nozzles on
the cleaning head rotate around two axles and thus
cover every part of the container.
● The cleaning head rotates by means of an electric
motor. The rotary speed is therefore constant and
not dependent on the pressure and volume of clean-
ing fluid.
● There is an adjustable bunghole cone on the sup-
port tube which is placed on the opening of the con-
tainer.
Safety instructions
● Observe the applicable national regulations.
5
● Observe the safety instructions provided with the
5
detergent used (usually on the packaging label).
5
● To prevent dangers due to incorrect operation, the
5
system may only be operated by persons who have
5
been instructed in the handling of the system, who
5
have verified their ability to operate the system and
5
who have been authorised and commissioned to
use the system.
6
● The operating instructions must be accessible to all
6
operators.
6
● The high-pressure pump used must be equipped
6
with all the safety devices specified by the corre-
6
sponding CE marking.
6
● Observe the operating instructions and the safety in-
6
structions for the high-pressure pump used.
6
Incorrect operation or misuse of the device can endan-
ger the operator and other persons through:
6
● high pressure
6
● high electrical voltage
● Detergent or cleaning fluid used
DANGER
Danger of crushing due to the drive of the interior clean-
er. Only operate the interior cleaner drive in closed con-
tainers.
DANGER
There is risk of injury from the escaping high-pressure
jet. Therefore, only operate interior cleaners in closed
containers.
DANGER
Health hazard from residues in the containers being
cleaned or from the cleaning fluid used. Therefore, fol-
low the prescribed protective measures.
DANGER
Risk of injury from the interior cleaner falling over at low
immersion depth. In this case, secure the interior clean-
er additionally.
DANGER
There is a danger of injury due to the container falling
over. Therefore, additionally secure the container and
interior cleaner.
ATTENTION
To avoid damage to the cleaning head, ensure that it is
positioned freely in the container. The cleaning head
must not hit the container wall under any circumstances.
Authorised operators
Authorised operators are persons who have reached
the age of 18 and are qualified to operate this system
(exceptions for trainees, see BGV D15 §6).
Behavior in the event of an emergency
1. Switch off the separate high-pressure pump.
2. Pull out the mains plug.
3. Close the cleaning fluid supply.

DANGER
Danger from high electrical voltage
Lethal danger
Only have the required electrical installation carried out
by a qualified electrician.
Note
A power supply is not included in the scope of delivery.
● The socket must be protected by a fault current pro-
tection switch with a trigger current of 30 mA.
● The socket must be close to the workplace so that
the mains plug can be pulled out quickly in an emer-
gency.
● Position the on-site power supply so that it is pro-
tected from spray water. If this is not possible, a wa-
terproof power supply must be used.
Mounting the spray nozzles
● The interior cleaner is equipped with 2 screw plugs
as standard. The spray nozzles must be ordered
separately.
● Depending on the flow rate and the pressure of the
high-pressure pump, different spray nozzles can be
used (see tables).
● Before switching on the high-pressure pump, the
minimum pressure value of the control valve must
be set. In this way, the interior cleaner is not subject-
ed to pressure peaks during start-up.
