too small or too large may damage the collet.

hole (turn spindle to align holes).

nut slightly by turning counter-
clockwise. Insert shank of the
accessory into the collet. Tighten
chuck nut with wrench, keeping pin in pilot hole. Test for
a secure hold by pulling on accessory. Remove pin.
Handpieces H.8, H.8D, and H.8SJ
These handpieces have a chuck
guard that slides back when
changing collets and accessories.

wrenches shown at right, for
opening and closing the collet.
Use one wrench to hold the
spindle and the other to unscrew the chuck nut by turning
counterclockwise.
Changing Collets

come with your handpiece are
for holding burs and other acces-
sories with different shank sizes.
