USE
WARNING : To provide adequate cooling
for the handpiece, always activate it with the
irrigation circuit correctly installed and filled.
To fill the irrigation circuit, always use the
PUMP function.
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 : Only use original
Piezosurgery/Mectron inserts, accessories,
and spare parts.
WARNING : Use of non-original
Piezosurgery/Mectron inserts: this use
entails finite damage to the handpiece
threading, thus compromising correct
operation and risking to cause harm to the
patient.
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 console 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 Piezosurgery/Mectron
torque wrench to fasten the insert to the
handpiece. Do not use any other tools, such
as pliers, pincers, etc.
CAUTION: The handpiece, because of its
shape, can roll. The handpiece must always
be placed on its holder when not in use.
WARNING : The patient must not come
into contact with the device body or the foot
pedal.
WARNING : Do not change the insert or
carry out any maintenance activities when the
handpiece is operating; the operator may be
injured.
WARNING : During the tightening and
removing operations, the user must pay
particular attention to avoiding injury from
inserts with sharp points and cutting edges.
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 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. Use of a worn-out insert
reduces the cutting performance and can
cause necrosis of the bone surface treated.
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.
CAUTION : Never force the cord-
handpiece connector into its seat on the
device as the cord-handpiece connector
and/or the device can be damaged. If the
connector cannot be easily fitted into its seat,
probably the connector and its seat do not
correctly match. Ensure that the connector
index point of the cord-handpiece is placed
upwards.
CAUTION : To avoid damaging the foot
pedal cable, connect and/or disconnect it,
holding it by the connector only. Never pull
the cable.
