ASSEMBLY
WARNING!
To reduce the risk of injury, always unplug tool
before attaching or removing accessories. Use
only specifically recommended accessories.
Others may be hazardous.
Installing Bits into Keyed Chucks (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 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.
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 informa
tion 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 on page 4.
