Change of Clutch Spring (see picture)
To avoid loosing parts, it is recommended to only disassemble
the machine on top of a flat work surface.
1. Prior to change of clutch spring, disconnect driver from air / power
supply.
2. Unscrew spring sleeve complete (left hand thread).
3. Unscrew clutch bearing complete (left hand thread).
4. Take out the complete clutch.
5. Put wrench 805492 (AF 6) onto the hex of the clutch shaft and screw off
adjustment nut by means of wrench 805491 (AF 11) (right-hand thread).
6. Draw off lock ring.
7. Take off clutch spring and assemble clutch in reverse order.
8. Introduce clutch complete into the clutch bearing and screw the latter on
to the screwdriver.
The hex of the clutch shaft must engage with the hex of the
gear support resp. spindle (located in gearing).
Check this and ensure that engagement lift on the spindle is
available (only push-to-start-screwdriver).
9. Re-adjust the clutch to the required torque (see chapter Torque
Adjustment ).
