Safety Speed Table Guidelines
7
•Never use bent or damaged burs.
•Do not force any burs into the collet chuck and always check after insertion if the bur is securely
locked by pulling the bur.
•Always operate at a safe speed for the size and weight of the bur. Start at 0 while slowly increasing
speed and securely gripping the handpiece. Operating at higher speeds often does not cut any better
or faster and can increase wear on the bearings in the handpiece as well as the cutting tool.
•Follow basic safe speed operation according to the chart below and also the safety speed ratings of
manufacturer of the burs.
•Never operate without a bur properly locked in the handpiece.
•After usage, remove any excess dust or debris.
•Do not operate near water or moisture.
•Avoid any chemicals and disinfectants.
