Safety instructions for all operations
1. Use the auxiliary handle(s). Loss of control can
cause personal injury.
2. Hold the power tool by insulated gripping sur-
faces, when performing an operation where the
cutting accessory may contact hidden wiring.
Cutting accessory contacting a "live" wire may
make exposed metal parts of the power tool "live"
and could give the operator an electric shock.
3. Always be sure you have a firm footing. Be
sure no one is below when using the tool in
high locations.
4. Hold the tool firmly.
5. Keep hands away from rotating parts.
Do not leave the tool running. Operate the tool

immediately after operation; they may be
extremely hot and could burn your skin.
8. Some material contains chemicals which may be
toxic. Take caution to prevent dust inhalation and
skin contact. Follow material supplier safety data.
9. 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.
10. If something wrong with the tool such as abnor-
mal sounds, stop operating immediately and
ask your local Makita Service Center for repair.
Before operation, make sure that there is no
11.
buried object such as electric pipe, water pipe
or gas pipe in the ground. Otherwise, the tool
may touch them, resulting an electric shock, elec-
trical leakage or gas leak.
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.
