SHUT-DOWN (FIG. 1, PG. 2)

Release the trigger in order to stop the tool.

When changing drills or accessories, always disconnect air supply to avoid injury.

OPERATING INSTRUCTIONS

Mark the desired drilling location with an awl or punch to provide a seat for the tip of the bit.

Place drill bit tip on location of mark and apply pressure to trigger to start drill. If drilling metal, apply lubricant to reduce friction and glazing.

Apply constant, even pressure while guiding the drill.

Reduce pressure before cutting through workpiece.

Continue depressing trigger until bit is fully removed from the drilled hole.

WARNING: Use of safety glasses and a breathing mask is

recommended. Drilling certain materials may create hazardous dust

which may require special breathing equipment. Check before using

the tool. Although the tool has a low noise level, the actual drilling

process may cause a noise level such that ear protectors will be required. Safety gloves are recommended.

CAUTION: Drill bit or surface may become extremely hot during drilling. DO NOT touch until cooled.
