CAUTION
The cap cannot be set between the numerals "1, 4, 7
... 22" or the black dots.
Do not use with the cap numeral between "22" and
the black 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 cap position according to the
screw diameter.
(2) Tightening torque indication
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, 4, 7 ... 22" on the cap, and the black
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 cap and line up the numbers "1, 4, 7 ... 22"
on the cap, or the black dots, 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
The motor rotation may be locked to cease while the
unit is used as drill. While operating the impact driver
drill, take care not to lock the motor.
Too long hammering may cause the screw broken
due to excessive tightening.
3. Rotation to Impact changeover (See Fig. 5)
The "Rotation (Rotation only)" and "Impact (Impact
+ Rotation)" can be switched by aligning the drill
mark " " or the hammer mark " " with the triangle
mark on the outer body.
To make holes in the metal, wood or plastic, switch
to "Rotation (Rotation only)".
To make holes in bricks or concrete blocks, switch to
"Impact (Impact + Rotation)".
CAUTION
If an operation which is normally performed at the
"Rotation" setting is performed at "Impact " setting,
the effect of making holes does not only increase but
it may also damage the bit or other parts.

4. Change rotation speed
By making a combination of the switch-over of "HIGH"
or "LOW" with the shift knob and the switch-over of
Power mode (P) or Save mode (S) with the lever on
the side of the handle, the rotational speed can be set
to four (4) steps. (See "SPECIFICATIONS".)
How to switch over "HIGH" or "LOW"
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.
How to switch over the Power mode (P) or Save
mode (S)
To set to the Power mode (P), slide the lever on the
side of handle to the lower side, and to set to the Save
mode (S), slide the lever to the upper side. (Fig. 9)
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 "HIGH" (high speed)
and the position of the cap is bitween "16" and "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
off. If the motor is locked for a while, the motor or
battery may be burnt.
In the work of the save mode (S), avoid the continuous
screw-tightening as temperature of electronic
components of the converter switch increases.
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.
