• If the chuck is left closed for an extended period without a bur inserted, it could become difficult to insert the bur.
• Be sure to insert the Bur Stopper in the chuck before inserting a CA Bur. Once trapped in the chuck without the Bur Stopper, the bur will be
difficult to remove.
• Do not use a HP Bur in combination with the Bur Stopper as the bur will not be fully secured and may disengage from the chuck, causing an
injury.
• Do not use Short Shank CA burs as the bur will not be fully secured and may disengage from the chuck, causing an injury.
5. Check before treatment
Check for handpiece vibration, noise and overheating. If any abnormalities are found do not use the handpiece and contact your Authorized NSK Dealer.
