Read the original instructions before using 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.
The packing materials can be recycled. Please dispose of packaging in accordance with the environmental regulations.
Electrical and electronic devices contain valuable, 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 environment. 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.

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%)
Only KÄRCHER detergents may be used.
The device may not be operated in explosive environments.
The device must not be operated with explosive and flammable substances!
Do not allow waste water containing mineral oil to penetrate soil, waterways or the sewage system.
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 cleaning fluid.
There is an adjustable bunghole cone on the support tube which is placed on the opening of the container.
Observe the applicable national regulations.
Observe the safety instructions provided with the detergent used (usually on the packaging label).
To prevent dangers due to incorrect operation, the system may only be operated by persons who have been instructed in the handling of the system, who have verified their ability to operate the system and who have been authorised and commissioned to use the system.
The operating instructions must be accessible to all operators.
The high-pressure pump used must be equipped with all the safety devices specified by the corresponding CE marking.
Observe the operating instructions and the safety instructions for the high-pressure pump used.
Incorrect operation or misuse of the device can endanger the operator and other persons through:
high pressure
high electrical voltage
Detergent or cleaning fluid used
Danger of crushing due to the drive of the interior cleaner. Only operate the interior cleaner drive in closed containers.
There is risk of injury from the escaping high-pressure jet. Therefore, only operate interior cleaners in closed containers.
Health hazard from residues in the containers being cleaned or from the cleaning fluid used. Therefore, follow the prescribed protective measures.
Risk of injury from the interior cleaner falling over at low immersion depth. In this case, secure the interior cleaner additionally.
There is a danger of injury due to the container falling over. Therefore, additionally secure the container and interior cleaner.
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 are persons who have reached the age of 18 and are qualified to operate this system (exceptions for trainees, see BGV D15 §6).
Switch off the separate high-pressure pump.
Pull out the mains plug.
Close the cleaning fluid supply.

The use of a dirt filter in the water line is recommended, but the filter should be cleaned regularly.
Danger from high electrical voltage
Lethal danger
Only have the required electrical installation carried out by a qualified electrician.
A power supply is not included in the scope of delivery.
The socket must be protected by a fault current protection 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 emergency.
Position the on-site power supply so that it is protected from spray water. If this is not possible, a waterproof power supply must be used.
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 subjected to pressure peaks during start-up.

Mount the spray nozzles or screw plugs with Teflon tape.
Place the interior cleaner with the bunghole cone sitting on the carrier tube on the object to be cleaned.
Release the screw connection on the bunghole cone.
Set the immersion depth.
Tighten the screw connection on the bunghole cone.
Connect the separate high-pressure pump to the indoor cleaner using a high-pressure hose.
High-pressure jet
Risk of injury from escaping, possibly hot high-pressure jet
Only operate the interior cleaner in containers that are closed on all sides.
Switch off the separate high-pressure pump and the interior cleaner's own drive if you want to insert the interior cleaner into the container or transfer it to another container.
Try to arrange the interior cleaner centrally.
Recommendation: Carry out 1 cleaning cycle if the container is slightly to moderately soiled and 2 cleaning cycles if it is heavily soiled. The duration per cycle is 6 minutes.
Connect the interior cleaner to the on-site power supply.
Connect the mains plug.
Open the cleaning fluid supply.
Switch on the separate high-pressure pump.
Switch on the interior cleaner at the power switch. The indicator light lights up.
Perform cleaning.
Rinse the interior cleaner for 30 seconds without adding detergents before shutting down. This prevents encrustation and sticking and thus premature wear and tear of the seals.
Switch off the interior cleaner at the power switch. The indicator light goes out.
Pull out the mains plug.
Switch off the separate high-pressure pump.
Close the cleaning fluid supply.
Remove the interior cleaner from the container.
