7.4 Depth stop DC UNI FF
The depth stop allows you to insert a screw to a
defi ned depth. You can set the dimension to which
the screw head is to project over the workpiece, or
to which it is to be countersunk in the workpiece.
Assembly

driver [8-1].
Pull the release ring [8-2] forwards.
Turn it until the hexagonal pin of the stop engages
in the internal hexagon support of the machine.
Press to stop onto the machine spindle. Let go of
the release ring.
Disassembly
Pull the release ring [8-2] forwards and then re-
move the depth stop from the spindle.
Tool change
Take sleeve A or B off the depth stop. Insert the
corresponding bit or plug-in bit adapter in the mag-
netic holder [8-3]. Refi t sleeve A or B.
Setting the depth
