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. 6) 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" on the clutch dial, and a black dot. 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. 6) Rotate the clutch dial and line up the numbers "1, 5, 9, ... 21" on the clutch dial, or the black dot, 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. ● 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. 7. Check the rotational direction. The bit rotates clockwise (viewed from the rear side) by pushing the R-side of the selector button. The L-side of the selector button is pushed to turn the bit counterclockwise (See Fig. 8).
