key and insert the collet. Hold the collet in place
and tighten down the drawbar by hand. With the air pressure valve on, place your
part in the collet and tighten the drawbar until it stops. Back off ¼-½ turn then turn
the air off. The collet will clamp your part with maximum holding power.

and tighten the drawbar until it stops. This is your starting point for adjustment at
the loose end. Turn the air pressure valve on and tighten the drawbar ¼-½ turn.
Turn the air off and the collet will begin to clamp your part. Repeat until you achieve
the desired amount of clamping force.
