DANGER: To ensure that the handpiece
cools down, always activate it with the
irrigation circuit correctly installed and
filled. To fill the irrigation circuit, always
use the CLEAN function.
WARNING: To correctly use the device,
you must press the foot pedal and start
it with the insert not making contact
with the part to be treated, so that the
electronic circuit can recognize the best
point of resonance of the insert without
interferences, allowing its optimal
performance.
DANGER: Before every treatment, make
sure that the insert appropriate for the
treatment is inserted on the handpiece.
Exclusively use the Mectron torque wrench
to fasten the insert to the handpiece.
DANGER: The patient must not come
into contact with the device body or the
foot pedal.
DANGER: Do not change the insert
while the handpiece is operating, to
prevent causing wounds to the operator.
WARNING: CLEAN function. After the
device is used with aggressive and non-
aggressive solutions, it is necessary to
perform a cleaning cycle on the tubes and
the handpiece with the CLEAN function
(see Chapter 06 - CLEAN FUNCTION). If the
tubes are not cleaned, the crystallization of
the salts may seriously damage the device.
WARNING: CLEAN function. The
CLEAN function must be used after every
treatment, before starting the cleaning and
sterilization procedures.
DANGER: Breakage and wear-out of
the inserts. High frequency oscillations and
wear-out may, in rare circumstances, lead
to the breakage of the insert.
Do not bend, change shape of, or
re-sharpen an insert in any way.
Bending an insert or applying leverage on
it can lead to its breakage.
Deformed or otherwise damaged inserts
are susceptible to breakage during their
use. These inserts must never be used.
Excessive pressure on the inserts during
their use can lead to their breakage.
If an insert breaks, check that none of its
fragments remain in the treated part and,
at the same time, apply effective suction
to remove them.
The patient must be instructed to breathe
through his nose during the treatment,
or a dental dam must be used to prevent
the patient from ingesting fragments of
broken inserts.
When the nitride coating wears out, the
cutting efficiency decreases; re-sharpening
the insert damages it and is therefore
forbidden. Check that the insert is not
worn out.
During the intervention, frequently
check that the insert is intact, especially
its top.
During the intervention, avoid prolonged
contact with retractors or with metallic
instrumentation in use.
WARNING: Contraindications.
Allow reusable, autoclavable items (the
handpiece, the inserts, the torque wrench,
and any other accessory that can be
sterilized ) to gradually return to room
temperature after steam sterilization and
prior to usage. The cooling process must
not be accelerated.
WARNING: The electrical contacts of
both handpiece and cord connectors must
be dry. Before connecting the handpiece
to its cord make sure that the electrical
contacts of both connectors,
dry, especially after the sterilization cycle
in autoclave. If need be, dry the contacts by
blowing compressed air onto them.
