CAUTION
The clutch dial cannot be set between the numerals
○
"1, 3, 5 ... 22" or the dots.
Do not use with the clutch dial numeral between
○
"22" and the line at the middle of the drill mark.
Doing so may cause damage (See Fig. 6).
2. Tightening torque adjustment
(1) Tightening torque
Tightening torque should correspond in its intensity to
the screw diameter. When too strong torque is used, the screw head may be broken or be
injured. Be sure to adjust the clutch dial position according to the screw diameter.
(2) Tightening torque indication
The tightening torque diff 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 the dots. The tightening torque at position "1" is the weakest and the torque is strongest
at the highest number (See Fig. 5 on page 29).
(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, confi rm that the switch is off .
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 is not engaged and that the motor
is locked. In such a case, please set the shift knob to
"LOW" (low speed).
