INTRODUCTION
As production continues, changes will be intro-
duced successively to the chain saw. If at any
time these changes influence service and/or
spares, special service announcements will be
sent out, which means that this manual will cease
to be current with time. In order to avoid prob-
lems, the manual should always be read together
with all service announcements that apply to the
specific model of chain saw.
Layout
The descriptive sections in this workshop manual
are set out in a number of flow diagrams. When
carrying out repairs on a specific chain saw,
follow the signs that apply to the saw in question.
Diagrams are not numbered as they are linked to
the actual text, either by lines or by being in the
same box.
Positional directives to components inside the
diagrams are designated with A, B, etc. and start
from A again in each new section.

Safety
Note!
The section dealing with safety should be
read and understood by all who carry out
repair or service work on the chain saw.
Target group
There are warning symbols on the chain saw. If a
warning symbol has been damaged or is missing,
it must be replaced immediately in order to
maximise safety when the saw is in use.
This workshop manual is written for personnel
that are assumed to have general knowledge of
service and repair of small engines.
The workshop manual should be read and under-
stood by all personnel carrying out service and
repair work on the chain saw. The manual is also
suitable for use in the training of new employees.
