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 diff ers 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.
(3) Adjusting the tightening torque
Rotate the clutch dial and line up the numbers "1, 4,
7 ... 22" on the clutch dial, or the black 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
hammer 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 "Hammer
(Hammer + 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
"Hammer (Hammer + Rotation)".
CAUTION
● If an operation which is normally performed at
the "Rotation" setting is performed at "Hammer"
setting,the eff ect of making holes does not only
increase but it may also damage the bit or other
parts.

● If it is hard to turn the cap to hammer mark
" " position, turn the chuck slightly in either
direction and then turn the cap to hammer mark
" " position again.
4. 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.
Low 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
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.
● 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.
