DRILLING
See Figure 9,
• Check the direction of rotation selector for the correct
setting (forward or reverse).
Fig. 9
• Secure the material to be drilled 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.
m Depress the switch trigger to start the dritl.
III 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 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.
n When drilling hard, smooth surfaces, use a center
punch to mark the desired hole location. This will pre-
vent the drill bit from slipping off-center asthe hole is
started.
• When drilling metals, use a light oil on the drill bit to
keep itfrom overheating, The oil will !_rolong the life of
the bit and increase the drilling action.
n If the bit jams in the workpiece or if the drilt stalls,
stop the toot immediately. Remove the bit from the
workpiece and determine the reason for jamming,
NOTE: This drill has an electric brake. When the switch
trigger is released, the chuck stops turning, When the
brake is functioning properly, sparks wilt be visible through
the vent slots on the housing. This is normal and is the
action of the brake.
