WARNING: Infection control.
For maximum patient and operator safety,
before using all the parts and reusable
accessories, make sure they have been
previously cleaned and sterilised by following
the instructions in Chapter 8 on page 49
CAUTION: Contraindications. After
having autoclaved the handpiece, inserts,
torque wrench or any other sterilisable
accessory, wait for them to completely cool
down before reusing them.
WARNING: Insert Breakage and Wear.
High frequency oscillations and wear can, in
rare cases, lead to the breakage of the insert.
Deformed inserts or inserts that have been
otherwise damaged are prone 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.
The patient must be instructed to breathe
through the nose during the treatment, or
use a dental dam, so as to avoid ingesting
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.
WARNING: Exclusively use original
MECTRON inserts, accessories and spare
parts.
CAUTION: It is prohibited to make any
changes to this appliance.
WARNING: Contraindications - Jet
polisher. Patients wearing contact lenses
must remove them prior to receiving
treatment with the jet polisher.
WARNING: Contraindications -
Supragingival powder jet polisher. Do
not aim the air, supragingival powder, or
water jet onto the soft tissues or inside the
gingival sulcus. Failure to comply with this
prescription can cause a gingival tissue
emphysema (emphysema of the mucous and/
or subcutaneous). For this type of application,
use only subgingival powder.
! WARNING: Contraindications - Jet
polisher. Do not use the device near areas
subject to recent dental extraction and in
traumatised/damaged areas (or areas nearby)
due to the risk of emphysema.
