surfaces, when performing an operation where
the cutting accessory may contact hidden wir-
ing or its own cord. Cutting accessory contacting
a "live" wire may make exposed metal parts of the
power tool "live" and could give the operator an
electric shock.
4. Always be sure you have a firm footing. Be
sure no one is below when using the tool in
high locations.
5. Hold the tool firmly with both hands.
6. Keep hands away from rotating parts.
Do not leave the tool running. Operate the tool

only when hand-held.
8. Do not touch the drill bit or the workpiece
immediately after operation; they may be
extremely hot and could burn your skin.
9. Some material contains chemicals which may
be toxic. Take caution to prevent dust inhala-
tion and skin contact. Follow material supplier
safety data.
10. 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
Never operate at higher speed than the max-
1.
imum 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
