OPERATION
DRILLING
See Figure 5.
When drilling hard smooth surfaces, use a center punch
to mark the 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 the drill firmly and place the bit at the point to be
drilled. Depress the switch trigger to start the 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 at bit break-
through. 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 drill 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 the workpiece or if the drill stalls, release
the switch trigger immediately. Remove the bit from the
workpiece and determine the reason for jamming.

LEVEL
See Figure 5.
This dril has a level on top of the motor housing. It can
help to keep the drill bit level during operation.
