Introduction

This service manual contains
detailed descriptions of all the repair
and servicing procedures specific to
this power tool series.
As the design concept of model
MS 210, 230 and 250 chainsaws is
almost identical, the descriptions
and servicing procedures in thus
manual generally apply to all three
models. Differences are described
in detail.
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 troubleshooting
charts for all assemblies and
systems in this manual and the
"STIHL Service Training System".
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.

Servicing and repairs are made
considerably easier if the clamp (1)

machine on assembly stand (2)
5910 890 3100 so that one clamp
screw engages the outer 10 mm
bore (3) in the assembly stand.
To service the underside of the
machine (e.g. remove the oil pump),
turn the machine through
180 degrees and mount it so that
one clamp screw engages the inner
10 mm bore (1) in the assembly
stand.

Pull the hand guard back against
the front handle for this purpose.

replacement parts.
