Passo 2
Removal of Retaining Screw
-
Open up the jaws all the way and look for a retaining screw at the bottom of the chuck. If a screw is present, you will need to remove it before you can unscrew the chuck.
-
These retaining screws always have a left hand thread, so you'll have to turn clockwise to remove it.
-
Closing the jaws until they just touch the screwdriver can help to keep it centered (especially on slotted screws) and perpendicular.
-
The screw can be stubborn to come loose, especially if it has threadlocking compound on it or if it is rusty. An impact driver can work wonders here. And remember - clockwise!
