DRILLING
See Figure 11.
When drilling metals, use a light oil on the drill bit to
keep itfrom overheating. The oil will prolong the life of
the bit and increase the drilling action.
If the bitjams in workpiece or ifthe drill stalls, release
switch trigger immediately. Remove the bit from the
workpiece and determine the reason for jamming.
CHUCK REMOVAL
See Figures 12, 13, and 14.
The chuck must be removed inorder to use some
accessories. To remove:
• Lock switch trigger or your drill by placing the
direction of rotation selector incenter position.
See Figure 2.
• Inserta5/16 inch or larger hex key wrench into the
chuck ofyour drill and tighten the chuck jaws
securely.
• Tap the hex key wrench sharply with a mallet in a
clockwise direction. See Figure 13. This will
loosen the screw in the chuck for easy removal.

When drilling hard smooth surfaces use a center punch
to markdesired hole location. This willprevent the drill
bit from slippingoff center as the hole isstarted. How-
ever, the low speed feature allows starting holes without
center punching ifdesired. To accomplish this, simply
operate your ddll at a low speed until the hole is started.
The matedal to be ddlled should be secured in a vise or
Withclamps to keep it from turning as the drill bit rotates.
Hold toolfirmly and place the bit atthe point to be ddlled.
Depress the switch trigger to start tool.
Move the ddll bit into the workpiece applying only
enough pressure to keep the bit cutting. Do not force or
apply side pressure to elongate a hole.
WARNING: Be prepared for binding or bif
breakthrough. When these situations occur, drill
has a tendency to grab and kick opposite to the
direction of rotationand could cause lossof
control when breaking through material. If not
prepared, this loss of control can result in
possible serious injury.
