two-gear selector (4) into position 2 by aligning the number with mark on the housing
(20) (2nd gear).
Setting the drilling depth (DR650)

• Tighten the side handle by turning the grip clockwise.
Screwdriving with clutch drill (DR330)
This tool is fitted with a collar 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
