DRILLING
– cont’d
3. While holding the drill firmly, place the
point of the drill bit at the point to be
drilled. Depress the switch trigger to
start the drill.
4. Move the drill bit into the workpiece
applying only enough pressure to
keep the bit cutting. Do not force the
drill bit or apply sideways pressure to
elongate the hole.
Be prepared for binding and bit
breakthrough. When these situations
occur, the drill bit has the tendency to
grab the workpiece. This action will kick
the drill opposite to the direction of drill
bit rotation and could cause loss of
control when breaking through material
as you complete drilling the hole. If you
are not prepared, this loss of control
can result in possible serious injury.
When drilling metals, use a light oil on the
drill bit to keep it from overheating. The oil
will prolong the life of the drill bit and
improve the drill cutting action. If the bit
jams in the workpiece or if the drill stalls,
release the trigger switch immediately.
Remove the bit from the workpiece and
determine the reason for jamming.
CHUCK REMOVAL
The drill chuck must be removed in order
to use some accessories. To remove the
chuck:
1. Unplug the drill from the power
source.
2.
Insert a 5/16” or larger hex key (1) into
the chuck (2) and tighten the chuck
jaws securely. Make sure each of the
three chuck jaws (3) is seated on a flat
surface of the hex key (see Fig. 4).
3. Tap the hex key sharply with a mallet
(4) in a clockwise direction. This
action will loosen the screw in the
chuck for easy removal.
4. Open chuck jaws and remove hex
key.
5. Open chuck jaws as far as possible
using the chuck key.
6. Remove the chuck screw using a #2
Philips screwdriver (see Fig. 5) below.
NOTE: Turn screw CLOCKWISE to
remove it. This screw has a left
hand thread.
