DRILLING
See Figure 11.
OVERLOAD
Your drill has a built-in overload protsctor to protect
the motor during overloading or prolonged use. The
overloed protector automatically activates to break the
circuit. When this occurs, allow your drill to cool a few
seconds before resuming operation.
CHUCK
REMOVAL
See Figures 12, 13, and 14.
The chuck must be removed in order to use some
accessories. To remove:
•
Lock switch trigger on your drill by placing the
direction of rotation selector in center position.
See Figure 2.
•
Insert a 5/16 inch or larger hex key wrench into the
chuck of your drilland 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 ddlling hard smooth surfaces use a canter punch
to mark desired hole location. This will prevent the ddll
bit from slippingoff center as the hole is started. How-
ever, the low speed feature allows starting holes without
center punching if desired. To accomplish this, simply
operate your drillat a low speed until the hole is started.
The matedal to be ddlled should be secured in a vise or
with clamps to keep it from tuming as the ddll bit rotates.
Hold tool firmly and place the bit at the point to be ddlled.
Depress the switch trigger to start tool.
Move the ddn bit into the workpisce 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 bit
breakthrough. When these situations occur, drill
has a tendency to grab and kick opposite to the
direction of rotation and could cause loss of
control when breaking through material. If not
prepared, this loss of control can result in
possible serious injury.
When drilling metals, use a light oil on the ddll bit to
keep it from overheating. The oil will prolong the life of
the bit and increase the drilling action.
If the bit jams in workpiece or if the drill stalls, release
switch trigger immediately. Remove the bit from the
workpiece and determine the reason for jamming.
