CHUCK REMOVAL (FIG. 6)
Turn the adjustment collar (D) to the "drill" position and gear shifter
(E) to position 1 (low speed). Tighten the chuck around the shorter
end of a hex key (not supplied) of 1/4" (6.4 mm) or greater size.
Using a wooden mallet or similar object, strike the longer end in
the clockwise direction, as shown. This will loosen the screw inside
the chuck.
Open chuck jaws fully, insert screwdriver (or Torx tool if required)
into front of chuck between jaws to engage screw head. Remove
screw by turning clockwise (left-hand-thread). Place hex key in
chuck and tighten, as shown in Figure 6. Using a wooden mallet or
similar object, strike key sharply in the counterclockwise direction.
This will loosen the chuck so that it can be unscrewed by hand.
