Mectron compact piezo LED Mode D'emploi Et D'entretien page 21

WARNING: Before each treatment
ensure that the insert that is suitable for the
treatment is inserted on the handpiece.
Use only the Mectron torque wrench to
secure the insert to the handpiece.
WARNING: Do not change the insert
whilst the handpiece is in operation in order
to avoid causing injury to the operator.
WARNING: Insert Breakage and Wear.
High frequency oscillations and wear can, in
rare cases, lead to the breakage of the insert.
Deformed or damaged inserts are susceptible
to breakage during use. Broken or worn
inserts must not ever be used.
In the event of breakage check that no
fragments remain in the treated part and
at the same time use suction effectively to
remove them.
It is necessary to instruct the patient to
breathe through the nose during the
treatment, or use a dental dam, so as to avoid
to ingest fragments of broken inserts.
Check the state of wear of the insert and
its integrity before and during each use.
If a drop in performance occurs, see to its
replacement.
The state of wear of the most common
inserts (S1, S1-S, S2, S5, P2, P4, P10) can be
checked using the supplied INSERT-CARD. To
use the INSERT-CARD correctly:
• Position the insert on the INSERT-CARD
so that the profile corresponds to the
one printed on the card. The printed
profile on the card has a red line
indicating the limit of wear;
• If the insert is shorter than the limit of
wear, its performance will be significantly
inferior compared to that of a new insert,
and should therefore be replaced.
If the layer of titanium nitride (gold-plated
surface), where present, is visibly worn, the
insert must be replaced. The use of a worn
insert reduces its efficiency.
Diamond Inserts: diamond inserts must be
replaced when the layer of titanium nitride is
visibly worn and in any case after a maximum
of 10 treatments.
When the nitriding is consumed, the
cutting edge loses effectiveness; a possible
regrinding harms the insert, therefore it is
prohibited. Verify that the insert is not worn.
During the operation frequently check that
the insert is intact, especially in the apical
part.
During the operation avoid prolonged
contact with the retractor or with metal
instruments in use. Do not exert excessive
pressure on the inserts during use.
CAUTION: Contraindications. After
autoclaving the handpiece, the inserts, the
torque wrench, or any other sterilisable
accessory, wait until it has completely cooled
before reuse.
CAUTION: The electrical contacts
inside the connectors on the handpiece
and cord must be dry. Before connecting
the handpiece to its cord, make sure that the
electrical contacts of the connector on both
sides are perfectly dry, especially after the
sterilisation cycle in an autoclave. If necessary
dry the contacts by blowing them with
compressed air.
CAUTION: Owing to its conformation,
the handpiece can rotate. When not used the
handpiece must always be put back on its
support stand.
WARNING: During the intervention on
the patient, do not perform any maintenance
tasks on the system.
WARNING: Infection control. After
prolonged non-use of the dental unit, run a
water circuit cleaning cycle as indicated in the
user manual supplied by the manufacturer of
the dental unit.
