(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

⅜ 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.

⅜ 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.

⅜ To make holes in the metal, wood or plastic, switch

to “Rotation (Rotation only)”.

⅜ 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

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

⅜ 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.

⅜ 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).

⅜ 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.

Be sure to turn the shift knob.
