1.1 Introduction
This service manual contains
detailed descriptions of all the repair
and servicing procedures specific to
this power tool.
You should make use of the
illustrated parts lists while carrying
out repair work. They show the
installed positions of the individual
components and assemblies.
Refer to the latest edition of the
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
"Troubleshooting" and the
"STIHL Service Training System"
for all assemblies.
Refer to the “Technical Information”
bulletins for engineering changes
which have been introduced since
publication of this service manual.
Technical information bulletins also
supplement the parts list until a
revised edition is issued.
The special tools mentioned in the
descriptions are listed in the chapter
on "Special Servicing Tools" in this
manual. Use the part numbers to
identify the tools in the
"Special Tools" manual. The manual
lists all special servicing tools
currently available from STIHL.

Service manuals and all technical
information bulletins are intended
exclusively for the use of properly
equipped repair shops. They must
not be passed to third parties.
Servicing and repairs are made
considerably easier if the machine
is mounted to assembly stand (3)
5910 890 3100. To do this, secure
the mounting plate (2)
5910 850 1650 to the assembly
stand with two screws (1) and
washers.
The above operation is not
necessary with the new assembly
stand 5910 890 3101 since the
mounting plate is already fitted.

The screws must not project since
they, depending on the machine,
may damage housings when the
machine is clamped in position.
Preparations for servicing
The chain sprocket, saw chain and
guide bar must be removed to
mount the machine on the assembly
stand for servicing.
Engage the bar mounting studs in
the lower holes in the mounting
plate and secure the machine in
position with the M 8 nuts (arrows).
