WARNING:
Read all safety warnings, instruc-
tions, illustrations and specifications provided
with this power tool. Failure to follow all instructions
listed below may result in electric shock, fire and/or

surfaces, when performing an operation where
the cutting accessory or fasteners may contact
hidden wiring or its own cord. Cutting acces-
sory or fasteners contacting a "live" wire may
make exposed metal parts of the power tool "live"
and could give the operator an electric shock.
2. Always be sure you have a firm footing. Be sure no
one is below when using the tool in high locations.
3. Hold the tool firmly.
Keep hands away from rotating parts.
4.
5. Do not leave the tool running. Operate the tool
only when hand-held.
6. Do not touch the drill bit or the workpiece
immediately after operation; they may be
extremely hot and could burn your skin.
7. Some material contains chemicals which may be
toxic. Take caution to prevent dust inhalation and
skin contact. Follow material supplier safety data.
8. If the drill bit cannot be loosened even you
open the jaws, use pliers to pull it out. In such a
case, pulling out the drill bit by hand may result in
injury by its sharp edge.
Safety instructions when using long drill bits
1. Never operate at higher speed than the maximum
speed rating of the drill bit. At higher speeds, the
bit is likely to bend if allowed to rotate freely without
contacting the workpiece, resulting in personal injury.
2. Always start drilling at low speed and with the bit
tip in contact with the workpiece. At higher speeds,
the bit is likely to bend if allowed to rotate freely without
contacting the workpiece, resulting in personal injury.
3. Apply pressure only in direct line with the bit and do
not apply excessive pressure. Bits can bend causing
breakage or loss of control, resulting in personal injury.
SAVE THESE INSTRUCTIONS.
WARNING:
DO NOT let comfort or familiarity

rules stated in this instruction manual may cause
serious personal injury.
