(2) Tightening power indication
Tightening power should be changed according to
the screw type and the materials to be tightened.
Guidance of the tightening power is indicated on
the outer frame of this unit with numerals "1", "2",
"3", "4" and "5". The minimum power is from "1"
position and bigger the value the stronger is the
power (see Fig. 5).
(3) How to adjusts the tightening power
Rotate the cap and set to one of the numerals.
Adjust the power by cap rotation in such a way that
when the power is too strong, set to the next
smaller numeral and set to the next larger numeral
when too weak.
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

CAUTION
The selection examples shown in Table 2 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.
6. Mounting and dismounting of the bit.
(1) Mounting the bit
After inserting a driver bit, etc. into the keyless drill
chuck, firmly grasp the ring and tighten the sleeve
by turning it toward the right (in the clockwise
direction as viewed from the front). (See Fig. 8)

speed. Move the shift knob in the direction of the
arrow (see Figs. 6 and 7).
When the shift knob is set to "L", the drill rotates
at a low speed. When set to "H", 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 setting the shift knob to "H" (high speed) and
the position of the cap is "4" or "5", it may happen
that the clutch does not engaged and that the motor
is locked. In suh a case, please set the shift knob
to "L" (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.
4. The scope and suggestions for uses
The usable scope for various types of work based
on the mechanical structure of this unit is shown
in Table 1.
Use for drilling purpose.
Use the bit and socket matching the screw
diameter.
Use after drilling a preparatory hole.
L (Low speed)
If the sleeve becomes loose during operation, tighten
it further. The tightening force becomes stronger
when the sleeve is tightened.
(2) Dismounting the bit
Firmly grasp the ring and loosen the sleeve by
turning it toward the left (in the counterclockwise
direction as viewed from the front). (See Fig. 8)
