Bracing for forward rotation (Fig. 4)
Fig. 4
When drilling in forward, the bit will rotate in a clockwise direction. If the bit
binds in the hole, the bit will come to a sudden stop and drill will suddenly
react in a counterclockwise direction.
Figure 4 shows an example of a Super Hole-Shooter properly braced for
forward rotation.
A. Forward (clockwise) rotation
B. Reaction
C. Brace drill with pipe handle here
If the bit binds, the pipe handle or the motor housing braced against the
stud will hold the drill in position.
Bracing for reverse rotation (Fig. 5)
Fig. 5
When drilling in reverse, the bit will rotate in a counterclockwise direction.
If the bit binds in the hole, the bit will come to a sudden stop and the drill
will suddenly react in a clockwise direction.
Figure 5 shows an example of the Super Hole-Shooter properly braced for
reverse rotation.
A. Reverse (counterclockwise) rotation
B. Reaction
C. Brace drill with pipe handle here
If the bit binds, the pipe handle or the motor housing braced against the
stud will hold the drill in position.

Reversing (Fig. 6)
Fig. 6
A reversing switch is located below the trigger switch for removal of bits
from holes. Permit the motor to come to a complete stop before reversing.
Reversing the tool with the gears in motion may cause severe damage.
When removing selfeed bits from partially drilled holes, a fl ick of the trigger
switch will free the threaded pilot screw. When the threads are loose, lift the
bit from the workpiece with the motor stopped.
Drilling
Before drilling, clamp the material down securely. A poorly secured piece
of material may result in personal injury or inaccurate drilling. When drilling
in light gauge metal or wood, use a wooden block to back up the material
to prevent damage to the workpiece.
Mark the center of the hole to be drilled with a center punch to give the bit
a start and to prevent it from "walking." Lubricate the drill bit with cutting
oil when drilling iron or steel. Use a coolant when drilling nonferrous metals
such as copper, brass or aluminum.
To reduce the risk of injury, always wear eye protection.
Chuck Removal (Fig. 7)
This tool is equipped with a threaded spindle to hold the chuck. Before re-
moving the chuck, unplug the tool and open the chuck jaws. A left-handed
thread screw is located inside the chuck to prevent the chuck from loosening
when the tool is operated in reverse direction. Remove the screw by turning
it clockwise. To remove the chuck, hold the tool so that only the side of the
chuck rests fi rmly and squarely on a solid workbench. Insert the chuck key
or a chuck remover bar in one of the keyholes. Turn the chuck so the key
is at about a 30° angle to the bench top and strike the key sharply with a
hammer so the chuck turns
in a counterclockwise direc-
tion (looking from the front of
the tool). This should loosen
the chuck from the spindle
which has a right hand thread
making it easy to remove the
chuck by hand.
NOTE: When replacing the
chuck, always replace the
left hand thread screw in the
chuck.
