Rotary collet chuck:
By turning the rotary clamp mechanism, the collet mechanism opens or closes. This technology
makes it possible to fix a maximum number of grinding tools and ensures the maximum smooth
running while working.
All-in-one control knob:
Select running direction and rotational speed with one regulator at the same time through the
simplest operation.
Safety Stop:
If the device develops excessive speed and pressure during grinding, the electronics will
respond by switching off the device. In this case, you must set the rotation switch (D) of the
device to zero (middle position) and start the device again.

To ensure that the safety, reliability and performance of the unit are not adversely affected,
enhancements, readjustments, alterations or repairs are not permitted aside from those
performed by Promed authorized persons.
A. Keep the inner parts of the handpiece as free as possible from dust and grinding residue.
B. Remove dirt from the outer surface of the handpiece with a cloth moistened with alcohol.
Prevent moisture from entering the unit.
C. Only use grinding heads with a dental standard size of 2.332 - 2.350 mm (0.091 - 0.093
inches) and avoid using rusted or damaged grinding heads. Their false usage may lead
to excessive wear and tear in the ball bearings. Adhere to the safe speed and the safety
measures stipulated by the manufacturer.
D. Do not expose the handpiece to strong knocks as this may damage the ball bearings. If the
handpiece should fall down, check whether the grinding head is bent. Pay closer attention
to noise and/or heat generation. Send the handpiece immediately in for repair should it
be damaged.
E. Before cleaning the unit, make sure that it is turned off and disconnected from the electricity.
F. Do not use any aggressive substances such as scouring agents or other detergents as they
may corrode the surface.
