B. Carefully push the paddle back all the way to the rear and hold
it there. (See Picture #6)
C. In the bottom of the alignment port is a locating pin, (See Pic-
ture #7) and located on the nose of the chuck is a milled slot. (See
Picture #8) To insert the chuck into the alignment port, both the
pin and slot must be aligned.
For easier alignment, a reference line (See Picture #9) has been
milled on the O.D. of the chuck, as well as an alignment detent lo-
cated on to the face of the alignment port. (See Picture #10) By
aligning these two reference points you
have properly positioned the locating
pin and slot. If both are in alignment
you will be able to, successfully slide
the chuck into the alignment port. At
this point the chuck nose should be en-
tirely hidden inside the alignment port.
D. Grasp the shank of the drill bit and push it into the chuck to the
drill stop. (See Picture #11)
E. Release the paddle, but continue pushing the drill bit in against
the stop. The two pawls will close onto the drill bit. (See Picture#
12)
NOTE: Short drill bits may be aligned first without the chuck. After
aligning the short drills, slip the chuck over the drill bit and into the
alignment port and tighten the chuck jaws, securing the drill bit.
Before removing the chucked drill bit from the alignment port com-
pare the position of the drill bit against the pawls with the “correct”
illustration. (See Illustration #12b )
F. Look down into the viewing port in front of the paddle. Note the
location of the two spring steel pawls. Rotate the drill bit until the
pawls slip in and grab the flutes at the narrowest point. (See Pic-
ture #12 and Illustration #12b) Continue to push the drill bit
against the drill stop.
G. With the drill point against the drill stop and the pawls in the
flute of the drill, use the other hand to tighten the chuck by turning
the chuck knob clockwise. Push the paddle back again to release
the drill bit and remove the chuck and drill from the alignment
port. Snug the chuck knob clockwise using both hands to secure
the drill bit.
STEP 3: Sharpening the drill point
A. Push the Drill Sharpener switch to the ON ( | ) position.
