REMOVING THE CHUCK SCREW
Set the Speed Selector Slide (3a) to the #1 setting. With the aid of a small pencil tip torch (or use an air reduction nozzle on a heat gun) apply heat into the chuck opening, directly to the head of reversing screw just prior to removing the screw. Place a T40 1/4” torx bit into the head of the reversing screw and place a 1/4” boxed end wrench over the hex on the T40 bit. It is recommended to use a 12”-18” metal tube or pipe as leverage over the boxed wrench. In a clockwise direction apply a slow, steady force on the ‘cheater bar’ to break the screw loose.
REMOVING THE KEYLESS CHUCK
Tighten a 1/2” or 10mm Allen Key into the jaws of the chuck. Place the tool into a vise with soft jaws (this will require that you remove the belt clip from the tool). It is recommended to use a 12”-18” metal tube or pipe as leverage over the allen key. In a counter-clockwise direction apply a slow, steady force on the ‘cheater bar’ to break the chuck loose.
