Service Manuals and technical
information bulletins are intended
exclusively for the use of properly
equipped repair shops. They must
not be passed on to third parties.
Servicing and repairs are made
considerably easier if the machine
is mounted on assembly stand (3)
5910 890 3101. For this purpose,
secure the clamp (2)
5910 850 1650 to the assembly
stand with two screws (1).
The screws must not protrude, as
they may damage the housings
when clamping the machine,
depending on the machine.
The machine is guided with the
collar screw through the upper hole
of the clamping rail and fastened
using nut M 8 (arrow).
The machine is fastened to the
mount on the clamping rail by the
screw head on the crankcase.
