Introduction
For your safety and the safety of your patients
These operating instructions are intended to explain how to use your product. However,
we must also warn of possible dangerous situations. Your safety, the safety of your team
and, of course, the safety of your patients are very important to us.
Please observe the safety instructions!
Intended purpose
This treatment unit is used for the diagnosis and therapy of children and adults in the fi eld of dentistry.
Improper use can damage the treatment unit and thus pose risks and
hazards to the patient, user and third parties.
Qualifi cation of the user
The DKL treatment unit may only be used after medically, professionally and practically trained
personnel have been instructed. The development and design of the treatment unit were geared
towards the target group of dentists, dental hygienists, qualifi ed dental employees (prophylaxis) and
dental assistants.
Production according to EU directive
The medical device complies with the provisions of Directive 93/42/EEC.
0123
Responsibility of the manufacturer
The manufacturer can only be held responsible for the impact on the safety,
reliability and performance of the treatment unit if the following instructions
are observed:
> The dental unit must be used in accordance with these operating
instructions.
> If assembly, additions, new settings, changes or repair work is carried out
by DKL or trained technicians authorised by DKL or personnel of authorized
dealers trained by DKL.
> The electrical installation of the room must comply with the regulations of
the IEC 60364-7-710 standard („Erection of electrical installations in rooms
used for medical purposes“) or comply with the regulations applicable in
your country.
> The recommended annual maintenance is carried out and any repair work
in this context meets the requirements of EN 62353.
„Repeat tests and pre-commissioning tests of medical electrical equipment
and systems – general regulations“are fully complied with.
> The national legal regulations are observed when using the device, in
particular the applicable health and safety regulations and accident
prevention measures.

6
Electromagnetic Compatibility (EMC)
Medical electrical equipment is subject to special precautions with regard to EMC and
must be installed and commissioned in accordance with the EMC instructions. DKL
guarantees that the dental unit complies with the EMC guidelines only if original DKL
accessories and spare parts are used. The use of accessories and spare parts not
approved by DKL may lead to an increased emission of electromagnetic interference or
to a reduced resistance to electromagnetic interference.
The EMC manufacturer declaration can be found on page 46.
HF communication equipment
Do not use portable and mobile HF-communication equipment (such as mobile
telephones) during operation. These can aff ect medical electrical devices.
Risks due to electromagnetic fi elds
The functionality of implantable systems, such as cardiac pacemakers and
implantable cardioverter defi brillators (ICD), can be infl uenced by electric, magnetic and
electromagnetic fi elds.
> Before using the product, ask the patient and user about implanted systems and
check the use.
> Perform a risk-benefi t analysis.
> Do not place the product near implanted systems.
> Do not place the instruments on the patient‘s body.
> Take appropriate emergency precautions and respond immediately to health changes.
> Symptoms such as increased heart rate, irregular pulse, and dizziness may be signs
of problems with a pacemaker or ICD.

temperature for 24 hours.
> Before each application, check the treatment unit and the instruments with cables for
damage and loose parts.
> Do not operate the treatment unit if it is damaged.
> Check the set parameters each time you restart the unit.
> Carry out a test run before each application.
> The application and timely shutdown of the system is the user’s responsibility.
> Make sure that in the event of a device or instrument failure, the treatment can be
completed safely.
> Use only original DKL fuses.
> Never touch the patient and the electrical connection at the treatment unit at the same
time.
> Do not lean on the doctor‘s device, the assistant‘s device, the tray or the operating
lamp.
> When moving the treatment chair, the doctor‘s device, the assistant‘s device, the tray or
the operating lamp, pay attention to the patient and the practice personnel.

>Before putting the device into initial operation and after downtimes (weekends,
(public) holidays etc.), fl ush the water lines intensively.
> Flush all instrument connections for 2 minutes before starting work.
> Rinse used instruments for 20 seconds after each treatment.
Risk of injury or infection caused by instruments that are not in use:
The arrangement of the instruments may cause injury or infection to the hand and
forearm when accessing the tray or the display.
Therefore, when accessing the tray or the display, pay attention to the arrangement of
the instruments.
Safety notes – Transmission Instruments
> Do not exceed the maximum permissible load of 2 kg on the doctor‘s
device.
Follow the instructions and safety notes in the operating instructions for the
transmission instruments.
> For the motors, only use transmission instruments with transmission systems that are
ISO 3964 (DIN 13940) compatible and approved by the manufacturer.
> For air-powered instruments, only use coupling systems according to ISO 9168.
> For air-powered instruments, only use coupling systems with anti-retraction stop for
contaminated cooling water.
> Observe the information provided by the manufacturer of transmission instruments
regarding transmission ratio, maximum speed and maximum torque.
> Only use faultless instruments and with the motors pay attention to the direction of
rotation of the rotating instrument. Follow the manufacturer‘s instructions.
> Plug in the transmission instrument only when the device is at a standstill.
> If the coolant supply fails, switch off the transmission instrument immediately.
> Before each use, check the transmission instrument for damage and loose parts.
> Never operate the clamping mechanism of the transmission instrument while using
the device or while the device is running down.
> Never reach into the instrument while it is running or running down.
> Avoid overheating of the treatment site.
> Check the secure placement of the instrument.
Highly immunosuppressed patients or patients with specifi c lung diseases should not
