Caution
®
• Cercon mill is a handpiece used in dental
laboratory work for cutting while preventing
heat when performing fine work on porce-
lain teeth, porcelain and ceramics. Do not
use for other applications.
• When cutting, wear safety glasses, and use
a grinding box and vacuum for safety.
• Do not modify or disassemble unnecessarily.
Otherwise, performance and safety may be
seriously affected. Please ask your Cercon
mill dealer whenever repairs are required.
• Do not drop the handpiece and unit. Make
sure to put the unit on a horizontal and
stable surface.
• Observe the permissible speeds the ma-
nufacturer or dealer designates for the bur.
Otherwise, you may be injured by scattering
and breaking up of the bur.
• Do not use burs which are oscillating or bent
or damaged and of which shank portions
are worn. Otherwise, you may be injured by
scattering and breaking up of the bur.
• Do not turn the chuck release ring during
rotation of the handpiece. Otherwise, the
handpiece will be broken.
• Never supply lubricant to the handpiece. It
uses a grease filled bearing and additional
lubrication may cause failures.

• Pay careful attention to rattling, vibrations,
sounds and temperature (heating), and in-
spect by rotating in advance before starting
use. Immediately ask your dealer for repair
work if any irregularities are sensed.
• The proper air pressure is 0.25~0.35 MPa.
Pressure exceeding the value may lead to
premature failure of the bearing because of
excessive increases in speeds.

• Extract water if water drips or contaminants
are found on the filter of the unit.
• Always clean the shank of the bur you are
going to mount. Contaminant deposits in the
chuck may lead to oscillating of the bur and
breakage of the chuck.
• Install the cutting bur or test bur even when
not in use.
• Operational control, maintenance and in-
spection is the responsibility of each user.
