How do I adjust the torque settings for screwdriving?

The tool has a torque adjustment collar that allows you to select the operating mode and adjust torque for tightening screws. Start at the lowest torque setting, tighten the first screw, and if the clutch slips before achieving the desired result, increase the collar setting. Repeat until you reach the correct setting, then use that setting for remaining screws. (Page 9)
