REMOVING THE CHUCK
The chuck on the GH-24, GH-30 and the GH-45 is held on by a right hand, 8mm, socket head cap screw or
hex head bolt. To remove the chuck you must remove this bolt with an Allen wrench. However, if you
cannot hold the chuck and remove the bolt, you may have to make a tool to assist you. Use a piece of steel
having a width slightly less than the width of the slot in the chuck. In the center of the steel, place a hole
large enough for the Allen wrench or socket extension to go through. This steel will give you the holding
leverage necessary to break the bolt free. (See included figure) If the chuck doesn't come off immediately
after removing the screw, it may be necessary to gently tap the edge of the chuck with a rubber mallet.
Reassemble the new chuck in the reverse order.
