•Never use bent or damaged burs.
•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.
Safety Precautions!
CAUTION:
•The length of the bur as well as the weight of the material, type of type,
and durability and precision of the bur construction can also be a major
factor for maximum speed.
•Slowly increase the operating speed and stop immediately if any excessive
noise or vibration.
•Most cutting burs will perform best by constant gentle movement letting the
bur do the work.
•Turn off the main power switch when not in use to avoid power and electric current to the controller.
•Always check the handpiece carefully for smooth operation prior to each use.
•Do not use with any other brands of equipment as brushless units are not compatible with
other brands.
