These recommendations for times of use for the attach-
ments for Air Pen Drive have been determined under
average load with an ambient air temperature of
20 °C (68 °F).
Above mentioned duty cycles might need to be reduced
due to higher loads applied and due to ambient air tem-
peratures above 20°C (68°F). This needs to be taken into
consideration during the planning of the surgical inter-
vention.
Generally systems can heat up if in constant use. For this
reason the handpiece and the attachment should be al-
lowed to cool down for the above recommended peri-
ods of constant use. If this is observed the system will be
prevented from overheating and possibly harming the
patient or user. After the above indicated number of cy-
cles, the respective attachments must be allowed to cool
down for 30 minutes. The user is responsible for the ap-
plication and for turning off the system as prescribed. If
longer periods of constant use are required, an addi-
tional handpiece and/or attachment should be used.
For oral surgery it is recommended to prevent any con-
tact of warm components with soft tissues as already
temperatures around 45 °C may damage the lips and
oral mucosa.
Precautions:
•
Carefully observe the above recommended duty
cycles.
•
Always use new cutting tools to prevent heating up
of the system due to reduced cutting performance.
•
Careful maintenance of the system will reduce
heat development in the handpiece and the attach-
ments. The use of the maintenance unit
(05.001.099) is strongly recommended.
Warning:
The Air Pen Drive must not be stored or
operated in an explosive atmosphere.

For maximum 10 minutes.
