4. Insertion /Removal of the Bur
CAUTION
• Do not use non-standard burs. The ISO standard shank diameter is φ1.59 - φ1.60 mm.
• Do not exceed the bur speed recommended by the bur manufacturer. Moreover, do not use the bur which it has lower rotation speed.
• Do not use long surgical burs. Do not use burs longer than 26mm.
• Do not use short shank burs. (M600LG M4, M600LG B2, M600LG QD)
• Always keep the bur shank clean. Entry of hard debris into the chuck via the bur shank could cause rotation slip and also prevent the bur from
being securely located in the chuck.
• Fully depress the Push Button and insert the bur into the chuck until it is secure.
• Test that the bur is secure by gently pulling and pushing the bur without depressing the Push Button.
