DRILLING
See Figure 6 - 7.
Levels are located on the top and end of the motor housing
to help keep the drill bit level during use.

Depress and release the switch trigger to be sure the drill
is in the OFF position before connecting it to a power
supply.
 Check the direction of rotation selector for the correct
setting (forward or reverse).
 Secure the material to be drilled in a vise or with clamps
to keep it from turning as the drill bit rotates.
 Plug the drill into power supply. Hold the drill firmly and
place the bit at the point to be drilled.
 Depress the switch trigger to start the drill.
 Move the drill bit into the workpiece, applying only enough
pressure to keep the bit cutting. Do not force the drill or apply
side pressure to elongate a hole. Let the tool do the work.
WARNING :
Be prepared for binding at bit breakthrough. When these
situations occur, the drill has a tendency to grab and kick
in the opposite direction 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 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.
 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, stop
the tool immediately. Remove the bit from the workpiece
and determine the reason for jamming.
