Adjusting the fastening torque
The fastening torque can be adjusted infi- nitely from approx. 5 kg . cm (0.4ft . Ibs)to
37kg . cm (2.7 ft . Ibs).
To adjust it, loosen the two screws and turn the adjusting ring. Then tighten the screws to secure the adjusting ring. Refer to the table below fok relation between the numbers on the adjusting ring and the fastening torque to be obtained.

(Example)
10 kg . cm (0.7 ft . Ibs) of fastening torque can be obtained when the number 2 is aligned to the red mark.
NOTE:
Always tighten the two screws to secure the adjusting ring after adjusting the fastening torque.
Operation
The proper fastening torque may differ depending upon the kind or size of screws, the type of materialsto be fastened, the condition of the threads, etc. Beforestarting your job, always perform a test operation to verify adequate fastening torque.
Hold the tool firmly and place the point of the driver bit in the screw head. Apply forward pressure to the tool to the extent that the bit will not slip off the screw and turn the tool on. As soon as the screw becomes tight, the clutch will cut in and the motor will stop automatically. Release the trigger.
NOTE:
Hold the tool pointed straight at the screw, or the screw and/or bit may be damaged.
If the motor will not start even after you pull the trigger, release the trigger. Then pull the trigger again after turning the bit slightly with your fingers.
