2 Introduction and safety regulations
2.1 General
This Workshop Manual provides a comprehensive
description of how to trouble shoot, repair and
test the chain saw. A description of different safety
steps that must be taken during repair work is also
given.
2.2 Safety
Note: The section dealing with safety must be
read and understood by all those carrying out
repair work or service on the chain saw.
Warning symbols can be found in this Workshop
Manual and on the chain saw. See "Symbols on
the saw" and "Symbols in the Workshop Manual".
A new warning symbol decal must be applied as
soon as possible if a warning symbol on the chain
saw has been damaged or is missing so that the
greatest level of safety can be maintained when
using the chain saw.
2.3 Target group
This Workshop Manual is written for personnel with
general knowledge about the repair and service of
chain saws.
The Workshop Manual must be read and under-
stood by personnel who will carry out repair work
and service on the chain saw. The Manual is also
suitable for use when training new employees.
2.4 Changes
Any modifications to the chain saw will be gradu-
ally introduced into ongoing production. As these
modifications affect service and/or spare parts,
specific service information will be sent out on
each occasion. This means that in time this Work-
shop Manual will become out of date. In order to
prevent this, the Manual should be read together
with all service information concerning the chain
saw in question.
2.5 Tools
Special tools are required for some stages. All
service tools are listed in the Workshop Manual.
Usage is made apparent in each section.
Always use original Husqvarna:
