WARNING:
Always wear safety goggles or
safety glasses with side shields when operating
tools. Fairure to do so could result in objects
being thrown into your eyes, resulting in possible
serious injury.
DRILLING
See Figure 8.
When drilling metals, use a light oil on the drill bit to
keep it from overheating, The oil wirl 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.
CHUCK
REMOVAL
See Figures 9, 10, and 11.
The chuck must be removed in order to use some
accessories. To remove:
Lock the switch trigger by p_acing the direction of
rotation selector in center position.
Insert a 5/16 inch or larger allen wrench (hex key
wrench) into the chuck of your drill and tighten the
chuck jaws securely.
Tap the allen wrench sharply with a mallet in a
crockwise direction. See Figure 9. This will loosen
the screw in the chuck for easy removal,
MALLET
CHUCKJAWS
KEYLESS CHUCK
When drilling hard smooth surfaces use a center
punch to mark desired hole location. This will prevent
the drill bit from slipping off center as the hole is
started.
The material to be drilled should be secured in a vise
or with clamps to keep it from turning as the drill bit
rotates.
Hold tool firmly and place the bit at the point to be
drilled. Depress the switch trigger to start tool.
Move the drill 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 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.
