Insert drill bit into chuck far enough to obtain maximum gripping of the
chuck jaws (fig.21). The jaws are approximately 1" long. When using a
Jaws
small drill bit, do not insert it so far that the jaws touch the flutes (spiral
grooves) of the drill bit. Make sure the drill bit is centered in the chuck
before tightening the chuck with the key.
Tighten the drill bit sufficiently, so that it does not slip while drilling. Turn
the chuck key clockwise to tighten, counterclockwise to loosen.

POSITIONNING THE TABLE AND WORKPIECE
Lock the table to the column in a position so that the tip of the drill bit is
just a little above the top of the workpiece.
Always place backup material (wood, plywood...) on the table underneath
the workpiece. This will prevent "splintering" or making a heavy burr on
Workpiece
the underside of the workpiece as the drill bit breaks through. To keep the
backup material from spinning out of control, it must contact the left side
of the column, as illustrated in fig.22.

material
WARNING! If the backup material is not long enough to reach the left
side of the column, clamp it to the table. Failure to do this could result in
personnal injury.
For small workpieces that can't be clamp to the table, use a drill press vise
FIGURE 22
(optional accessory) (Fig.23). See authorized KING CANADA retailer for
more information on purchasing drill press vises.
WARNING! The vise must be clamped or bolted to the table to reduce the
risk of injury from spinning work or vise or tool breakage.
