INSTALLING DRILL BITS
WARNING: Never hold the chuck body with
one hand and use the drill power to rotate the
drill body to loosen or tighten bits. Serious in-
jury may result.
1. Remove the drill plug from the power
source.
2. Rotate the chuck collar
(1) to open or close the
jaws (2) to a point where
the opening is slightly
larger than the bit size
you intend to use (fig. 5).
3. Insert the bit into the chuck the full length
of the jaws. Raise the front of your drill slightly
to prevent the bit from falling out of the chuck
jaws.
4. Insert the chuck key (3) into one of the three
holes in the chuck body. Rotate the chuck key
clockwise until the drill bit is held firmly in
place by the chuck jaws.
NOTE: Do not use a wrench on the chuck key.
You may damage the key or the chuck.
WARNING: Do not
insert the drill bit into
the chuck and tighten as
shown in fig. 6.
The drill bit MUST be properly inserted with
all three chuck jaws holding the bit centered
in the chuck. Failure to properly insert the drill
bit could cause the drill bit to be thrown from
the chuck resulting in possible serious injury or
damage to the chuck.
REMOVING BITS
1. Remove the drill plug from the power
source.
2. Insert the chuck key into one of three holes
in the chuck body. Rotate chuck key counter-
clockwise until the chuck jaws release the drill

OPERATION INSTRUCTIONS

WARNING: Read instruction manual before
you operate this drill. Your safety depends
on it! Every time you use the drill you should
verify the following:
1. Chuck is tight.
2. Workpiece is properly secured.
3. Safety glasses are being worn.
Failure to adhere to these safety rules can
greatly increase the chances of injury.
DRILLING
When drilling in smooth hard surfaces such as
metal, use a centre punch to mark the desired
hole location. This will prevent the drill bit
from slipping off centre as the hole is started.
The workpiece to
drilled should be secured
in a vise or with clamps
to keep it from turning as
the drill bit rotates (fig. 7).
1. Check the drill bit to
make sure it is firmly
locked into the drill chuck
and the forward/ reverse
switch is in the forward
position.
2. Hold the drill firmly with
both hands. Use your left
hand to grasp the main
handle and switch and
your right hand to grasp
the side assist handle (fig.
7). If the side assist handle
cannot be used due to
inadequate space,
your right hand to grasp
the swivelling "D" handle
(fig. 8).
3. While holding the drill firmly, place the
point of the drill bit at the point to be drilled.
Squeeze the switch trigger to start the drill.
NOTE: Always use a higher drill speed when
drilling small holes. Use a slower drill speed
when drilling large holes.
4. Move the drill bit into the workpiece ap-
plying only enough pressure to keep the bit
cutting. Do not force the drill bit or apply side-
ways pressure to elongate the hole.
