relevant parts list to check the part
numbers of any replacement parts.
A fault on the machine may have
several causes. To help locate the
fault, consult the chapter on

Servicing and repairs are made
considerably easier if the machine
is mounted to assembly stand (3)
5910 890 3101. To do this, secure
the mounting plate (2)
5910 850 1650 to the assembly
stand with two screws (1) and
washers.
The screws must not project since
they, depending on the machine,
may damage housings when the
machine is clamped in position.
Preparations for servicing
Remove the chain sprocket cover,
saw chain, guide bar and clutch
drum before carrying out repairs
– the chain brake must be
disengaged.
Mount the machine to the assembly
stand for servicing and repair work.
Engage the bar mounting stud in the
outer bore in the mounting plate and
secure the machine in position with
the M 8 nut (arrow).

The machine is held in position on
the mounting plate by the screw

STIHL parts symbol K. This
symbol may appear alone on small
