sories. Only use accessories specifically
recommended for this tool. Others may be
hazardous.
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").
Installing Bits
Always remove the battery before inserting or
removing bits. Select the proper style and size bit
for the application.
Installing Bits into Keyed Chucks
1. Remove the battery pack.
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 lin-
ing up properly.
3.
4. Place the chuck key in each of the three holes
in the chuck, turning it clockwise to tighten the
chuck securely.
NOTE:
Never use a wrench or means other than
a chuck key to tighten or loosen the chuck.
5. To remove the bit, insert the chuck key into
one of the holes in the chuck and turn it coun-
terclockwise.
Bit binding
If the bit binds, the drill will suddenly react in the
opposite direction of the rotation of the bit. Reduce
the chances of a sudden reaction by following the
instructions listed below. Prepare for a sudden
reaction by holding or bracing securely.
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.
• Keep selfeed bits aligned with the work surface
so bits go in straight (see "Drilling").
• 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.
If the bit does bind:
1. Release the trigger immediately.
2. Reverse the motor.
3. Remove the bit from the work and start again.
4. Do not pull the trigger on and off to attempt to
start a stalled bit. This will damage the drill.
Warning
To reduce the risk of injury,
wear safety goggles or glasses with side
shields.
Warning
To reduce the risk of per
-
sonal injury when drilling, hold the tool by isu
-
lated gripping surfaces when performing an
operation where the cutting tool may contact
hidden wiring. Contact with a "live" wire will
make exposed metal parts of the tool "live"
and shock the operator
Warning
To reduce the risk of injury,
hold or brace securely. Always be prepared
for bit binding and drill reaction.

Insert the bit into the chuck. Center the bit in the
chuck jaws and lift it about 1.6 mm (1/16") off of the
bottom. Tighten the chuck jaws by hand to align
the bit.
