1.2. INDICATIONS FOR USE
The CEFLA Dental Micromotors are brushless electric micromotors controlled by a control unit inside CEFLA Dental Units.
They are intended to be connected with an ISO-type handpiece attachment: straight or contra-angle of equal, gear-reducing, or gear increasing speed.
They are intended for professional use in dental surgery such as: preventive dentistry, restorative applications, endodontic treatment, prosthetic
applications and implantology practices.
Read carefully the user manual before using Micromotor.
The use of the device must respect the instructions provided.
1.3. IMPORTANT WARNINGS
For the correct interpretation of the indications in this manual the Italian text is binding.
•The device is not suitable for use with blends of inflammable anaesthetics and oxygen or nitrous oxide.
•The instrument is provided in a non-sterile state. Before use, proceed with the applicable reprocessing procedure as detailed in this manual.
•Use of electrically-powered devices may interfere with the operation of active implantable devices such as pacemakers or other active devices. In
case of doubt regarding the treatment of patients with such devices, consult a cardiology expert or another competent medical institute.
•During use of the device dust and fragments from the patient’s oral cavity or from the same device may be projected into the environment (organic
and inorganic dust and metal dust, fragments of the device or its tips and potentially infected biological material).
•Protect the patient, when possible, using a dental dam.
•Instruct the patient to breathe through the nose in cases where the dam is not applicable.
•Medical personnel must put on suitable personal protection equipment.
•Suitably cool the surgical field during use.
•Use only handpieces and counterangles approved and legally marketed in your country.
•Use only burrs (or other similar tools) approved and legally marketed in your country and made with biocompatible materials complying with ISO
10993-1 and whose dimensions comply with EN ISO1797-1 standards.
•Use only lubricant approved and legally marketed in your country for dental handpieces.
•Before each use, verify the proper locking of the handpiece onto the micro-motor and of the burr onto the handpiece chuck.
•Do not use damaged or worn handpieces.
•Make sure that during operation of the motor there is full flow of cooling air. In the absence of cooling stop using the device and call authorised
technical service assistance.
•In case of visible damage, the emission of unusual noises and/or vibrations or if overheating is noticed, do not use the device and call authorised
technical service assistance.
•LED radiation: do not stare into beam or view directly with optical instruments.
The manufacturer will not be held responsible regarding safety, reliability or performance of the device if:
•The essential requirements for the location, detailed in the Dental Unit User Manual are not respected;
•The assembly, the additions, the adjustments, the calibrations and/or the repairs are not performed by authorised technical service personnel;
•If modifications, tampering, incorrect maintenance have been performed, or incompatible and/or non-original spare parts have been used on the
device;
•The device is not used in compliance with the use instructions and its intended use.
CONTRAINDICATIONS
There are no contraindications related to the use of micromotors because they are not intended to get in contact with the patient.

3. OPERATION OF THE DEVICE
3.1. CONNECTION TO THE POWER SUPPLY INSTRUMENT TUBING
Bring the motor next to the instrument tubing and rotate it, on the connector itself until the coupling point is found. Insert the motor completely and then
fully tighten the ring nut.
3.2. CONNECTION AND DISCONNECTION OF THE HANDPIECE
Handpieces complying with ISO 3964 and with the INTRAmatic®Lux. type may be used. Insert the handpiece on the coupling until the connection “click”
is heard.
Never mount a handpiece onto a motor that is running.
To detach the handpiece from the motor pull lightly.
3.3. OPERATING PARAMETERS
Operational modes, speed adjustment, inversion of the rotation direction, continous or reciprocating movements, torque adjustment, spray and LED
lighting activation (if available) are to be made through the Dental Unit command panel. Refer to the Dental Unit instruction manual for the setting of the
operational parameters.
3.4. ILLUMINATION DEVICE
In the micro-motors set up with LEDs for lighting of the surgical field, these light up automatically when the micro-motor is running.
After the motor stops, the LED remains lighted for a pre-set time. Lighting depends on settings made on the Dental Unit.

4. REPROCESSING
RACCOMANDATION: reprocess shall be performed within 30 minutes of the end of use.
The micromotors have been tested for 250 cycles (as required by EN ISO 14457).
Before sanitisation operations, the operator must detach the handpiece from the micromotor and the micromotor from the dental
units tubing.
Before reprocessing, visually inspect the micromotor. Reprocess only micromotors free of any unacceptable deterioration such as
corrosion and damages.
To maintain a level of hygienic security, at the end of each use and within a short time he must clean, disinfect and sterilize the
micromotor.
4.1. CLEANING
For cleaning follow the instructions below:
•Create a cleaning solution following the instructions for light organic debris.
Use a cleaner that is legally marketed and approved in your country (see paragraph PRODUCTS TO BE USED).
•Soak a lint-free cloth in the prepared detergent solution and tightly wrap the micromotor for 2 minutes.
Pay particular attention to have the cloth contact the front and rear connections of the device.
•Unwrap the device and dispose of the wipe.
•Soak a new lint-free cloth in the detergent solution and wipe the device by the following:
1 Wipe the external surface. Repeat this step using a fresh portion of the wipe if any visible soil remains.
2 Wipe the mating surface where the handpiece connects by wrapping the shaft housing with the wipe and rotating the device. Repeat this step with
a fresh portion of the wipe if visible soil remains.
3 Wipe the edge of the anterior mating surface. Press the wipe against the surface and rotate the device a few times both clockwise and
counterclockwise. Repeat this step with a fresh portion of the wipe if visible soil is observed.
Pay particular attention to the screw heads, recesses, and crevices of the device.
4 Wipe the edge of the rear mating surface of the device. Press the wipe against the surface of the device and rotate the device.
5 Repeat only step 4.1.
•Soak a new lint-free cloth in water (do not use saline solution) and wipe the micromotor by the following:
1 Wipe the external surface.
2 Wipe the mating surface between the handpiece and micromotor by wiping the stud and rotating the device a few times clockwise and
counterclockwise.
3 Wipe the edge of the anterior mating surface. Press the wipe against the surface to achieve good contact and rotate the device a few times both
clockwise and anti-clockwise.
4 Wipe the edge of the rear mating surface of the device. Press the wipe against the surface to have good contact and rotate the device a few
times.
•Using compressed air, dry the article.
•Using a new clean lint-free cloth, wipe the device to remove any excess of water or lubricant.
VISUAL INSPECTION.
At the end of the cleaning procedure, visually inspect the device under normal lighting conditions.
If any visible soil is present, repeat the cleaning procedure.

4.2. STERILISATION
Before each autoclave cycle lubricate the micromotor with a quick squirt of a lubricant for dental handpieces legally marketed and approved in your
country (see paragraph PRODUCTS TO BE USED).
Spray the lubrificant into the central hole in the back side of the micromotor only.
Reconnect the motor onto the instrument tubing and activate it so as to expel the excess lubricant.
Dry the outside of the micromotor with gauze or cotton wool before proceeding on with sterilisation.
