ASSEMBLY
To reduce the risk of injury, always
WARNING
unplug tool before changing or
removing accessories. Only use accessories
specifically recommended for this tool. Others
may be hazardous.
Installing Bits into Keyed Chucks
1. Unplug tool.
2. Open the chuck jaws
wide enough to insert
the bit. Be sure the bit
shank and chuck jaws
are clean. Dirt parti-
cles may prevent the
bit from lining up prop-
erly.
3. Insert the bit into the
chuck. Center the bit
in the chuck jaws and
lift it about 1/16" off of the bottom. Then, tighten
the chuck jaws by hand to align the bit.
4. Place the chuck key in each of the three holes in
the chuck, turning it clockwise as shown. Tighten
securely.
5. To remove the bit, insert the chuck key into one of
the holes in the chuck and turn it counterclockwise.
Installing Bits into Morse Taper Sockets
A No. 3 Morse Taper Socket is furnished as standard
equipment on Super Hole-Shooter Cat. No. 2404-1.
Before inserting the drill bit, be sure its taper matches
the socket taper. To insert drill bit, push the shank of the
bit firmly into the socket. This is all that is necessary to
properly seat the bit for drilling. Always keep the taper
shanks clean, free of nicks and coated with a film of oil.
To remove the bit from the socket, unscrew the
knurled taper socket cap and pull out the bit and the
socket. Once removed, the bit can be gently knocked
free with a soft metal mallet. Replace the socket and
the knurled cap.
Bit Selection
• Use sharp bits. Sharp bits are less likely to bind
when drilling.
• Use the proper bit for the job. There are many types
of bits designed for specific purposes. Check the
information on the bit's packaging for proper usage.
• Do not use bits larger than the rated capacity of the
drill. Gear damage or motor overload may result (see
"Specifications").
Pipe Handle
Thread pipe handle into the threaded hole in the
motor housing.
OPERATION
To reduce the risk of injury, always
WARNING
wear proper eye protection marked
to comply with ANSI Z87.1.
When working in dusty situations, wear appro-
priate respiratory protection or use an OSHA
compliant dust extraction solution.
To reduce the risk of personal injury when drill-
ing, always hold tool by the insulated gripping
surfaces when performing an operation where
the cutting tool may contact hidden wiring or its
own cord. Contact with a "live" wire will make
exposed metal parts of the tool "live" and shock
the operator.
When drilling, always brace the drill against a
solid fixed object (such as a stud) in preparation
for a sudden reaction.
When drilling, never use your body to brace drill.
Never put your hands (or other body parts) be-
tween the part of the drill being braced and the
object it is being braced against. Hands (or other
body parts) that are in the path of the reaction
can be pinched, crushed or broken.
Bit Binding
If the bit binds, the drill will suddenly react in the
opposite direction of the rotation of the bit.
Bit Binding Reaction
A. Forward (clockwise) rotation
B. Reaction
The operator should reduce the chances of a sudden
reaction by following the instructions listed below.
The operator should also prepare for a sudden re-
action by holding securely using the pipe handle or
bracing against a solid fixed object.
To reduce the chance of bit binding:
• Use sharp bits. Sharp bits are less likely to bind
when drilling.
• Use the proper bit for the job. There are many types
of bits designed for specific purposes.
• Avoid drilling warped, wet, knotty, and or pitchy
material if possible.
• Avoid drilling in material that you suspect contains hid-
den nails or other things that may cause the bit to bind.
The direction of reaction is always opposite of the
direction of bit rotation.
Reaction is even more likely to occur when enlarging
already existing holes and at the point when the bit
breaks through the other side of the material.
