8-1-2. Removal of the drill chuck
The Drill Chuck 4 4 [4] <4> is secured to the Spindle 5 5 [5] <5> with 1/2"-20UNF (Right Hand) and the
Special Screw (Left Hand) M6 x 23 1 1 [1] <1>. At first, open the chuck jaw as far as possible and loosen
the Special Screw by turning it clockwise.
a. Hold the drill so that only the Drill Chuck 4 4 [4] <4> rest firmly and squarely on the edge of a solid bench.
Install the hex. bar wrench into the Drill Chuck. Turn the Drill Chuck until the wrench is at about a 30˚ angle to
the bench top and strike the wrench sharply with a hammer so the drill chuck turns in the counterclockwise
direction. (Fig. 15)
If the Drill Chuck cannot be removed by striking the wrench, do not strike the wrench forcibly and try another
way as follows.
b. Hold the Spindle 5 5 [5] <5> with the open-end wrench secured to the vise as shown in Fig. 16.
Mount the pipe to the hex. bar wrench. Turn the hex. bar wrench counterclockwise to loosen the drill chuck.
