TOOL ASSEMBLY

To reduce the risk of injury, always unplug tool before attaching or
removing accessories or making adjustments. Use only specifi cally
recommended accessories. Others may be hazardous.
Installing Bits into Keyed Chucks (Fig. 1)
Fig. 1
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 particles may prevent the bit from lining
up properly.
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 (Fig. 2)
Fig. 2
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
fi rmly 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 fi lm 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 specifi c 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 "Specifi cations").
Pipe Handle
Thread pipe handle into the threaded hole in the motor housing.
WARNING!
OPERATION
To reduce the risk of injury, wear safety goggles or glasses with
side shields. Unplug the tool before changing accessories or mak-
ing adjustments.
To reduce the risk of personal injury when drilling, 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 fi xed 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) between 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 (Fig. 3)
Fig. 3
If the bit binds, the drill will suddenly react in the opposite direction of the
rotation of the bit. Figure 3 shows the path of reaction, (B) if the drill bit binds
while being driven in forward (A).The operator should reduce the chances of
a sudden reaction by following the instructions listed below.
The operator should also prepare for a sudden reaction by holding securely
using the pipe handle or bracing against a solid fi xed 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 specifi c purposes.
• Avoid drilling warped, wet, knotty, and or pitchy material if possible.
• Avoid drilling in material that you suspect contains hidden 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.
