Installing Drill Bits (Fig. 3)
WARNING: Never hold the chuck body with one hand and use the drill power to rotate the drill body to loosen or tighten bits.
Serious injury may result.
• Remove drill plug from the power source.
• Rotate chuck collar (1) in a counter clockwise direction until the chuck jaws (2) open wide enough to accept the bit (3).
• Insert the bit into the chuck the full length of the jaws or until the spiral portion of the bit is near the chuck jaws. Raise the
front of your drill slightly to prevent the bit from falling out of the chuck jaws.
• Tighten the chuck jaws onto the bit by turning the chuck body in a clockwise direction.
• NOTE: Make sure the bit is properly aligned in the jaws and NOT at an angle. An improperly aligned bit could be thrown from
the chuck when the drill is started.
• Finish tightening the chuck jaws by inserting the chuck key (4) into one of three holes (5) in the chuck body. Rotate chuck key
clockwise until drill bit is held firmly in place by the chuck jaws.
