CAUTION
• Do not use burs with problems listed below as the bur may break, seize up or disengage from the chuck.
- Bent, deformed, worn, rusted, broken, deficient bur.
- Bur which is cracked on the edge or axis.
- Non-ISO(EN ISO) standard, or tampered bur.
• Do not use burs other than specified in "10. Specifications" as such burs may be accidentally released or break during rotation.
• Always keep the bur shank clean. Dirt or 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 bearings or accidental release of the bur
may occur.
• Do not exceed Max. Bur Length shown in "10. Specifications".
• Do not use a surgical bur with its maximum length of 25mm or longer. Using such bur with this handpiece may lead to premature abrasion of
the bearings. In addition, sudden release, bend or breakage of the bur may occur.
• Always follow the instructions provided by the bur manufacturer.
• Do not exceed the bur speed recommended by the bur manufacturer.
• Do not mount or remove the bur until the motor has completely stopped.
• Do not apply excess pressure to the bur as it may break or bend or become difficult to remove.
