CAUTION
• Do not use non-standard burs. The ISO standard shank diameter is Ø1.5.9-Ø1.60mm
• Fully depress the Push Button and insert the bur into the chuck until bur is secure.
• Do not use bur when removing the crown, do not use bur to pry loose the crown. It may cause a malfunction in the handpiece.
• Do not apply too much pressure to the bur. Bur may break or bend and become difficult to remove.
• Do not use any bur longer than 18.5mm.
• Do not use bent, worn, damaged, or non-concentric burs. Such burs can cause damage to the handpiece.
• Do not exceed the bur speed recommended by the bur manufacturer.
• Always use clean burs. Unclean burs may allow debris to build up inside chuck, causing weak bur retention or premature chuck wear.
• When using shorter-than-short burs make certain the head/diamonds do not come in contact with the chucking mechanism.
