Always insert the bur all the way into the chuck. If insertion is insufficient, premature failure of the
bearings or accidental release of the bur may occur.
Ř
Do not exceed Max. Bur Length shown in "16. Specifications".
Ř
Always follow the instructions provided by the bur manufacturer.
Ř
Do not exceed the bur speed recommended by the bur manufacturer.
Ř
Do not insert or remove the bur until the rotation has completely stopped.
