Mectron COMPACT PIEZO LED Mode D'emploi Et D'entretien page 10

WARNING: Contraindications. Do not
perform scaling treatments without water
spray in order to avoid the insert over-hea-
ting which may cause damages to the tooth.
Treatments with no water spray can be car-
ried out only with "Dry Work" inserts which
do not have the water passage.
WARNING: Treatments that require
irrigation. Always check operation of the
irrigation before and during use. Make sure
the fluid outflows from the insert.
Do not use the device if the irrigation does
not work or if the pump is defective.
WARNING: Checking device status
before the treatment. Always check that
there is no water underneath the device.
Before every treatment, always check that
the device works perfectly and that the
accessories are efficient. DO NOT use the
device and its accessories if damage is
apparent. Contact an Authorized Mectron
Service Center if the abnormalities concern
the device.
CAUTION: Do not activate the
handpiece while the insert is in contact
with the part to be treated. Doing so, will
not allow the electronic control circuit
of the device to recognize the best point
of resonance of the insert, required for
efficient and optimum performance.
WARNING: Before every treatment,
make sure that the insert appropriate for
the treatment is inserted on the handpiece.
Exclusively use the original Mectron
torque wrench to fasten the insert to the
handpiece.
WARNING: Do not change the insert
with handpiece running, to prevent
causing wounds to the operator.
WARNING: Control of infections.
First Use The reusable accessories (brand
new or returned by service) are delivered
in NON-STERILE conditions and must
be prepared prior to use by applying
the procedures given in Chapter 06 -
CLEANING AND STERILIZATION.
Every use Once used, each reusable
accessory must be thoroughly reprocessed
prior to reuse, according to the procedures
given in Chapter 06 - CLEANING AND
STERILIZATION.
CAUTION: 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.
CAUTION: The electrical contacts inside
the cord and handpiece connectors must
be dry. Before connecting the handpiece
to the cord, make sure that the electrical
contacts of both connectors are perfectly
dry, especially after the sterilization cycle
in autoclave. If need be, dry the contacts by
blowing compressed air onto them.
WARNING: 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 applied to insert during
its use can cause insert fracture.
Should an insert fracture during use, 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. Prior to each use 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.
