CAUTION
It is recommended that a bur be kept in the chuck at all times. Do not operate the
handpiece without a bur in the chuck.
•
Use only recommended burs.
•
Always be sure chuck is free of dirt or debris before replacing a bur.
•
After replacing a bur, make sure that the Collet Chuck is fully closed before running the Motor.
•
DO NOT to open the collet while the motor is running. It will damage the handpiece.
•
Always put the Handpiece on the Handpiece Cradle 21 or in Handpiece Holder 22 while not in
use. (Fig.7). Take special care not to drop it on the floor.
•
Thoroughly clean the Collet before reassembling. Clean at least once a week for
longer life.
•
Keep the Handpiece clean and free of dirt and debris during disassembly.
•
The spindle and the motor should be disassembled only by a qualified repair facility.
CAUTION
•
Never exceed the maximum rotation speed specified by the manufacturer or for the bur
being used.
•
Large burs, even when operated below maximum rated speed, may begin to vibrate. Speed
should be reduced immediately to prevent damage to the bur, handpiece, or operator.
•
Be sure to insert the Bur shank all the way, until it touches the back of the Collet Chuck. Then
tighten the Collet Chuck. If the Bur is used while not inserted completely, it is very dangerous
because vibration may cause it to come out, bend, or break.
