7.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 clutch dial position according to the screw diameter.

(2) Tightening torque indication (See Fig. 8)

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, 5, 9 ... 21” and black dots on the clutch dial. The tightening torque at position “1” is the weakest and the torque is strongest at the highest number.

(3) Adjusting the tightening torque (See Fig. 8) Rotate the clutch dial and line up the numbers “1, 5, 9 ... 21” or the dots on the clutch dial, 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 driver drill, take care not to lock the motor.

●When setting the shift knob to “HIGH” (high speed) and the position of the clutch dial is between “9” and “21”, 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).

English

●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.

●Too long hammering may cause the screw broken due to excessive tightening.
