With your free hand, insert the
Chuck into the Alignment Hole—
make sure the flat spots on the
Chuck match the flat spots in
the hole.
At this point, the Chuck
should be inserted into the
Alignment Hole with the
flat spots hidden, and the
Chuck should be locked in the hole.

With the Alignment Button held
in, push the drill bit forward until
it is against the Drill Stop.
Look at the drill bit through
the Window over the
Alignment Hole—it should be
against the Drill Stop.
Release the Alignment Button.
While looking in the Window,
turn the drill bit to the right until
you feel the Bit Clamps grip
the bit at its narrowest
point (the bit is now difficult
to turn either way).
Turn the Chuck Knob to the right
until it is tight but make sure that
the bit did not turn or the Chuck
did not back out of the Hole.
