Introduction And Safety Instructions - Husqvarna Jonsered CS 2245 Workshop Manual

2 Introduction and safety instructions

2.1 General
This Workshop Manual describes in detail how the
chain saw is to be fault traced, repaired and tested.
A description of different safety measures that
should 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 decal must be applied as soon as possible if a
warning symbol on the chain saw has been da-
maged or is missing so that the greatest possible
safety can be obtained 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
Modifi cations will be successively introduced on
the chain saw during production. When these
modifi cations affect the service and/or spare parts,
separate 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shop Manual will become out of date.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 evident from respective sections.
Always use Husqvarna's original:
• Spare parts
