Installing Bits into Keyed Chucks
Be sure that the shank of the bit and the
chuck jaws are clean. Dirt particles may
cause the bit to line up improperly. Do not
use bits larger than the maximum recom-
mended capacity of the drill because gear
damage or motor overloading may result.
For best performance, be sure that the bits
are properly sharpened before use.
