・ 

DLC1213: This controller features the speed and soft start control. 

・ 

Speed control: Set low speed for small size screw and high speed for larger screws. 

・ 

Soft start: Set quick start when using higher torque or fastening a tapping screw, otherwise, the 

tool may not fasten screw. 

 

 
          CAUTION

 

Implement the operation properly. Insufficiently pressed blade or inadequately pulled lever may
