Drill safety warnings
Safety instructions for all operations
1. Hold the power tool by insulated gripping
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.
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, the workpiece or
chips 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 inhala-
tion 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.
9. Make sure there are no electrical cables, water
pipes, gas pipes etc. that could cause a hazard
if damaged by use of the tool.
Safety instructions when using long drill bits
1. Never operate at higher speed than the max-
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.
Always start drilling at low speed and with the
2.
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

Reversing switch action
CAUTION:
Always check the direction of

When changing the direction of rota-
tion, be sure to fully set the reversing switch to
position A side or B side. Otherwise, when the
switch trigger is pulled, the motor may not rotate or
the tool may not work properly.
This tool has a reversing switch to change the direction
of rotation. Move the reversing switch lever to the posi-
