CAUTION
• Do not use burs other than specified in "9. Specifications" as such burs may be accidentally released or break during rotation.
• Always keep the bur shank clean. Debris in the chuck could cause poor bur concentricity or low chuck retention force.
• Always insert the bur all the way into the chuck. If insertion is insufficient, premature failure of the handpiece head bearings, or accidental release of the bur, may occur.
• Do not exceed Max. Bur Length shown in "9. Specifications".
• Always follow the instructions provided by the bur manufacturer.
• Do not exceed the bur speed recommended by the bur manufacturer.
• Do not insert or remove the bur until rotation has completely stopped.
• Do not apply excess pressure to the bur as it may break or bend and become difficult to remove.
