•Do not force any burs into the collet chuck and always check after insertion 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.
