WARNING!
• Be sure to attach the belt hook securely
to the main unit with the screw firmly
fastened. When the belt hook is not
firmly attached to the main unit, the
hook may disconnect and the tool may
fall. This may result in an accident or
injury.
• Periodically check screw for tightness.
If found to be loose, tighten firmly.
• Be sure to attach the belt hook firmly
and securely onto a waist belt or other
belt. Pay attention that the tool does
not slip off the belt. This may result in
an accident or injury.
• When the tool is held by the belt hook,
avoid jumping or running with it. Doing
so may cause the hook to slip and the
tool may fall. This may result in an
accident or injury.
• When the tool is hooked onto the waist
belt by the belt hook, do not attach
driver bits to the tool. A sharp edge
object, such as a drill bit, may cause
injury or an accident.

goes out.
• Avoid using the tool in a way that causes
the overheating protection feature to
activate repeatedly.
• If the tool is operated continuously under
high-load conditions or if it is used in
hot-temperature conditions (such as
during summer), the overheating protec-
tion feature may activate frequently.
• If the tool is used in cold-temperature
conditions (such as during winter) or if it
is frequently stopped during use, the
overheating protection feature may not
activate.
