Reversible, Keyless Chuck, Unlock | Craftsman 315.27994 guide

REVERSIBLE

See Figure 5.

This tool has the feature of being reversible. The direction of rotation is controlled by a selector located above the switch trigger. With the drill held in normal operating position, the direction of rotation selector should be positioned to the left of the switch for drilling. The drilling direction is reversed when the selector is to the right of the switch. When the selector is in center position, the switch trigger is locked.

_i CAUTION: To prevent gear damage, always allow chuck to come to a complete stop before changing the direction of rotation or the two speed gear train (hi-lo).

To stop, release switch trigger and allow the chuck to come to a complete stop.

_lb WARNING: Your drill should never be connected to power supply when you are assembling parts,

making adjustments, installing or removing drill bits, cleaning, or when not in use. Disconnecting your drill will prevent accidental starting that could cause serious personal injury.

KEYLESS CHUCK

See Figure 6.

A keyless chuck has been provided with your drill to allow for easy installation and removal of bits. As the name implies, you can hand tighten or release drill bits in the chuck jaws. Arrows on the chuck indicate which direction to rotate the chuck sleeve in order to LOCK (tighten) or UNLOCK (release) the chuck jaws. Loosen the chuck sleeve by rotating it counterclockwise with one hand. Insert drill bit straight into the chuck the full length of the

jaws, and tighten securely by rotating the chuck sleeve in clockwise direction.
