Operate the shift knob to change the rotational speed. Move the shift knob in the direction
of the arrow. (See Fig. 20 and 21)
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, confirm that the switch is off.
Changing the speed while the motor is rotating will damage the gears.
● When a large force is required for operation (operations indicated in the following
chart) set the shift knob to “LOW”. If “HIGH” is set and the unit is used, it may cause
the motor to burn out or malfunction prematurely.
9. Confirm the cap position (See Fig. 22)
The tightening torque of this unit can be adjusted
according 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, 4, 7 ... 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:
● The cap cannot be set between the numerals “1, 4, 7
... 22” or the black dot.
● 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. 23)
10. 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.
