7. Operation
7.1 Inserting a screw

1. Insert the head of the screw into the socket at a
slight angle and then bring it into position between
the two jaws (fixed jaw and swiveling jaw) of the
attachment.
NOTE The screw can be brought into position
only from the chamfered side of the jaws.
2. The screw has been inserted correctly when the
two jaws close around the shank of the screw.
3. Check that the jaws have closed properly by trying
to move the screw from side to side slightly.
7.2 Setting the optimum screwdriving depth
1. Using the thumbwheel to set the optimum screw-
driving depth
2. Turning the thumbwheel counterclockwise causes
the screw to be driven deeper.
3. Drive a screw to test the screwdriving depth
setting.
NOTE The driving operation is completed only
when the two guide arms have opened completely
and the clutch of the screwdriver has disengaged.
Although the screwdriver continues to run, the
screw is driven no further.
4. Readjust the setting if necessary.
NOTE Each audible click of the thumbwheel
corresponds to a depth adjustment of 0.2 mm
(0.008 in).
5. Turning the thumbwheel clockwise causes the
screw to be driven less deeply.
