DRILLING
See Figures 7 - 8.
Levels are located on the top and end of the motor
housing to help keep the drill bit level during use.
n Depress and release the variable speed switch to be
sure the drill is in the OFF position before connecting it
to a power supply.
n Check the direction of rotation selector for the correct
setting (forward or reverse).
n Secure the material to be drilled in a vise or with
clamps to keep it from turning as the drill bit rotates.
n Plug the drill into power supply. Hold the drill firmly and
place the bit at the point to be drilled.
n Depress the variable speed switch to start the drill.
n 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.
n 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.
n 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.
n 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.
