holes. To release the bit, turn the chuck counterclockwise in just
one hole, then loosen the chuck by hand.
nOTE: When using hex shank or three‑sided shank bits, be sure
to align the flat sides of the bit with the chuck jaws to ensure
the bit is properly engaged by the jaws.

Drilling

WARNING: TO REDUCE THE RISK OF PERSONAL
INJURY, ALWAYS ensure workpiece is anchored or
clamped firmly. If drilling thin material, use a wood
"back-up" block to prevent damage to the material.
1. Use sharp drill bits only. For WOOD, use twist drill bits, spade
bits, auger bits, self‑feed bits, or hole saws. For METAL, use
steel twist drill bits or hole saws.
2. Always apply pressure in a straight line with the bit. Use
enough pressure to keep drill biting, but do not push hard
enough to stall the motor or deflect the bit.
3. Hold tool firmly with both hands to control the twisting
action of the drill.
4. IF DRILL STALLS, it is usually because it is being overloaded
or improperly used. RELEASE TRIGGER IMMEDIATELY,
remove drill bit from work, and determine cause of stalling.
