Adjusting Torque Control - Figure E
	E	3
This tool is fitted with a torque adjustment collar (3)
to select the operating mode and to set the torque for
tightening screws. Large screws and hard workpiece
materials require a higher torque setting than small
screws and soft workpiece materials.
• For drilling in wood, metal and plastics, set the
collar to the drilling position symbol
• For screwdriving, set the collar to the desired
setting. If you do not yet know the appropriate
setting, proceed as follows:
• Set the collar to the lowest torque setting.
• Tighten the first screw.
• If the clutch ratchets before the desired result is achieved, increase the collar setting
and continue tightening the screw. Repeat until you reach the correct setting. Use this
setting for the remaining screws.
