The contra-angles are intended for dental care (enamel work, removal of caries,
preparation of cavities and crowns, removal of fillings, finishing and polishing dental and
restoration surfaces). Any other form of use is forbidden and can cause danger.For this
contra-angle, we applied Community Directive 93/42/EEC, transposed by the French
regulations on medical equipment (Official Bulletin - L169 - 12 July 1993), as amended
by the 2007/47/CEE directive.
D
In accordance with these provisions, the contra-angle must only be used by
someone with experience of dental medicine for the application described,
and in compliance with the provisions in effect in relation to the prevention of
accidents at work, protection of employment and the instructions for use. This medical
device must be prepared and maintained only by people trained in the prevention of
infection, self-protection and protection of patients.
In accordance with these provisions, the user must :
• only use working instruments without defects,
• only use the contra-angle on drive units which comply with the directives of Standard
EN 60 601,
• observe correct use,
• protect themselves and the patient or third party against any danger,
• prevent all contamination by the product.
E
Pressure must be aadapted to the rotary instrument (refer to the manufacturer
of rotary instruments). We recommend an effort <2N for all speeds above
40000 rpm.
E
Before use, check that the contra-angle is not damaged and that no part is
missing. When inserting or changing the rotary instrument, make sure that
the contra-angle is stationary. After insertion of a rotary instrument, check
that it is correctly held by a slight rotary movement.
Do not handle the rotary instrument during operation.
Only operate the locking system when the motor is stopped.
Pressing the push button during the operation of the instrument may cause the rotor
to heat and the loss of the rotary instrument.
E
In order to cool the treatment area, only an adapted and correctly tempered
cooling spray should be used. Ensure that the spray is always sufficient and
regular (if not there is a risk to the health of the tooth and the adjacent tissue).
If there is no irrigation, the contra-angle must be taken out of use immediately.
If the nozzles are clogged in spite of cleaning, do not operate the contra-angle and
contact the after-sales service department.
E
In the event of visible malfunction or damage, immediately stop using the
instrument and inform your approved distributor or the manufacturer.
In the event of any questions on the equipment, contact either your approved
U
distributor or the manufacturer.
A poorly maintained instrument may overheat and cause unusually severe burns.
