Changing Accessories

Burs and other accessories can be inserted or removed from the handpiece collet when the collet is open. To open the collet:
1. Turn off the motor using the Motor On/Off Switch 3 and the Power Switch.
2. Twist the Chuck Handle in the “R” or release direction (clockwise) until the raised indicator bar clicks into the far left mark on the silver center ring.
3. Remove the accessory and replace it with another accessory. Insert the ‘new’ accessory shank fully into the collet for maximum support.
You should feel it touch the back of the collet.
4. Twist the knurled Chuck Handle toward the “S” or secure position by turning counter-clockwise until it snaps to lock the collet.
The accessory and the collet will be able to spin freely. The raised collet indicator bar will be above the far right mark in the silver center ring.
Note: The intermediate position between “S” and “R” holds both the spindle and the accessory in a locked position. It is useful to unscrew an over-tightened mandrel screw.
