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.
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 handpiece and cord connectors 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.
