6. Tool change on motorhandpiece
By turning the gripsleeve on the handpiece, the chuck can be opened or closed.
Only carry out a tool change when the motor is switched off! To optimise the precision and durability
of the chuck, the tool or the factory-supplied protective pin must always be in a fixed position,
even when not in use.
Always insert tools as far as possible into the chuck in order to achieve maximum holding power!
7. Operation
There is continuously variable speed control of the handpiece up to the maximum preset motor speed using
the respective control unit (see figure below).
The knee controller is equipped with an additional potentiometer for setting a speed limit.
Set the potentiometer to the desired maximum speed. By using the knee lever the speed can now be set
variously up to the pre-set speed.
Please always observe the maximum permitted speed for your tools!
