INSTALLINGBITS
See Figures 9 - 10.
[] Lock the switch trigger by placing the direction of
rotation selector in the center position.
[] Open or close the chuck jaws to a point where the
opening is slightly larger than the bit size you intend to
use. Also, raise the front of the drill slightly to keep the
bit from falling out of the chuck jaws.
[] Insert the drill bit.
_ WARNING: Make sure to insert the drill bit straight
into the chuck jaws. Do not insert the drill bit into the
chuck jaws at an angle then tighten, as shown in
figure 10. This could cause the drill bit to be thrown
from the drill, resulting in possible serious personal
injury or damage to the chuck.
[] Tighten the chuck jaws on the drill bit.
NOTE: Rotate the chuck body in the direction of the
arrow marked LOCK to tighten the chuck jaws. Do not
use a wrench to tighten or loosen the chuck jaws.

DRILLING
See Figures 11 - 12.
Levels are located on the top and end of the motor
housing to help keep the drill bit level during use.
[] 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.
[] 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, 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 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.
NOTE: This drill has an electric brake. When the switch
trigger is released, the chuck stops turning. When the
brake is functioning properly, sparks will be visible through
the vent slots on the housing. This is normal and is the
action of the brake.
