5. Confirm the cap position (see Fig. 9)
The tightening torque of this unit can be adjusted accord-
ing to the cap position, at which the cap is set.
(1) When using this unit as a screwdriver, line up the one of
the numbers “1, 3, 5 ... 22” on the cap, or the black dot, with
the triangle mark on the outer body.
(2) When using this unit as a drill, line up the cap drill mark
“
” with the triangle mark on the outer body.
CAUTION:
ⅷ The cap cannot be set between the numerals “1, 3, 5 ... 22”
or the black dot.
ⅷ Do not use with the cap numeral at “22” and the black line
at the middle of the drill mark. Doing so may cause
damage. (See Fig. 10)
6. Tightening torque adjustment
(1) Tightening torque
Tightening torque should correspond in its intensity to the screw diameter. When too
strong power is used, the screw head may be broken or be injured.
Be sure to adjust the cap position according to the screw diameter.
(2) Tightening torque indication (See Fig. 9)
The tightening torque differs 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 cap, and
a black dot. The tightening torque at position “1” is the weakest and the torque is
strongest at the highest number.
(3) Adjusting the tightening torque (See Fig. 9)
Rotate the cap and line up the numbers “1, 3, 5, ... 22” on the cap, or the black dot, with
the triangle mark on the outer body. Adjust the cap in the weak or the strong torque
direction according to the torque you need.
CAUTION:
ⅷ 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.
ⅷ When setting the shift knob to “HIGH” (high speed) and the position of the cap 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).
ⅷ 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.
ⅷ Too long hammering may cause the screw broken due to excessive tightening.
ⅷ A buzzing noise is produced when the motor is about to rotate; This is only a noise, not
a machine failure.
