A 1.3 Precautions
Safe operation and protection of the unit are
ensured only through proper use in accor-
dance with the instructions for use and
using the tools approved for the purpose.
The following should also be observed:
• the tool manufacturer's instructions,
• the work safety regulations,
• the accident prevention regulations.
■
Each time before switching on, check the
set speed.
■
Observe the permissible maximum speed
and maximum pressure of the tools
(according to tool manufacturer's
instructions).
■
Use safety screens when working with
rotating tools.
■
To avoid danger through accidental
switching on, place the handpiece on a
suitable shelf or tool support.
In the event of an unsatisfactory condition
of the unit or improper use, e.g.:
• unsuitable tools
• tool shafts not manufactured according to
DIN-ISO
• improper use or use not in accordance
with the purpose
• unapproved speeds for tools used
• incorrect clamping of the tools in the
chuck
• insufficient retaining force of the chuck
(wear, soiling, failure to follow the prod-
uct care instructions for the chuck system,
etc.)
• different sizes of tool shaft and chuck
• lack of regular cleaning of the chuck
• failure to follow the maintenance instruc-
tions
• failure to comply with the accident pre-
vention regulations (e.g. failure to use
safety screens, safety devices, handpiece
supports, etc.)
• failure to take into account signs of wear
and damage
• tool shafts which have slipped out (poten-
tial danger = bending of the tool shafts)
there is a danger of injury and damage to
material and unit, e.g. due to:
• Bending of the tool shafts
• Accidental withdrawal of the tools from
the chuck
• Breaking or splintering of the tool.
