the motor is locked. In such a case, please set the
shift knob to "LOW" (low speed).
If the motor is locked, immediately turn the power
off. If the motor is locked for a while, the motor or
battery may be burnt.

CAUTION:
The selection examples shown in Table 5 should be
considered as general standard. As different types of
tightening screws and different materials to be
tightened are used in actual works proper adjustments
are naturally necessary.
When using the driver drill with a machine screw at
HIGH (high speed), a screw may damage or a bit may
loose due to the tightning torque is too strong. Use
the driver drill at LOW (low speed) when using a
machine screw.
NOTE:
The use of the battery BAC-LI in a cold condition
(below 0 degree Centigrade) can sometimes result in
the weakened tightening torque and reduced amount
of work. This, however, is a temporary phenomenon,
and returns to normal when the battery warms up.
6. Using the hook
The hook is used to hang up the power tool to your
waist belt while working.
CAUTION:
When using the hook, hang up the power tool firmly
not to drop accidentally.
If the power tool is dropped, it may lead to an accident.
