opening is slightly larger than the bit size you intend to
use. Also, raise the front of the drill slightly to keep the
bit from falling out of the chuck jaws.

_I_ WARNING: Make sure to insert the drill bit straight
into the chuck jaws. Do not insert the drill bit into
the chuck jaws at an angle then tighten, as shown in
