(2) Tightening torque indication
The tightening torque di
ff
ers depending on the type of
screw and the material being tightened.
The unit indicates the tightening torque with the numbers
“1, 3, 5 ... 22” on the clutch dial, and a dots. The tightening
toque at position “1” is the weakest and the torque is
strongest at the highest number (See
Fig. 5)
.
(3) Adjusting the tightening torque
Rotate the clutch dial and line up the numbers “1, 3, 5 ...
22” on the clutch dial, or the dots, with the triangle mark
on the outer body. Adjust the clutch dial in the weak or the
strong torque direction according to the torque you need.
CAUTION
○
The motor rotation may be locked to cease while the unit
is used as drill. While operating the driver drill, take care
not to lock the motor.
○
Too long hammering may cause the screw broken due to
excessive tightening.
3. Change rotation speed
Operate the shift knob to change the rotational speed.
Move the shift knob in the direction of the arrow (See
Figs. 7
and
8
).
When the shift knob is set to “LOW”, the drill rotates at a
low speed. When set to “HIGH”, the drill rotates at a high
speed.
CAUTION
○
When changing the rotational speed with the shift knob,
con
fi
rm that the switch is o
ff
.
Changing the speed while the motor is rotating will
damage the gears.
○
When setting the shift knob to “HIGH” (high speed)
and the position of the clutch dial is “17” or “22”, it may
happen that the clutch does not engaged and that 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 o
ff
. If
the motor is locked for a while, the motor or battery may
be burnt.
○
To extend the lifetime, the lithium-ion battery equips with
the protection function to stop the output. Therefore, if the
tool is overloaded, the motor may stop. However, this is
not the trouble but the result of protection function. In this
case, release the switch of tool and eliminate the causes
of overloading.

Metal
For drilling with a metal working drill bit.
CAUTION
○
The selection examples shown in
Table 5
should be
considered as general standard. As di
ff
erent types of
tightening screws and di
ff
erent 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 BSL1415, BSL1815 and BSL1830
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.
