Introduction - Husqvarna 570 Workshop Manual

General
This Workshop Manual provides a comprehensive
description of how to trouble shoot, repair and test the
chainsaw. A description of different safety measures that
should be taken during repair work is also given.
Safety
Note! The section dealing with safety should be read
and understood by all who carry out repair and service
work on the chainsaw.
Warning symbols can be found in this Workshop Manual
and on the chainsaw. See page 3. A new warning symbol
must be applied as soon as possible if a warning symbol on
the chainsaw has been damaged or is missing to ensure
the greatest possible safety when using the chainsaw.
Target Group
When producing this Workshop Manual the assumption
has been made that personnel who use it have general
knowledge in the repair and service of small engines.
The Workshop Manual must be read and understood by
personnel who are to carry out repair work and service on
the chainsaw. The Manual is also suitable for use when
training new employees.
Modifications
Modifications will be successively introduced on the
chainsaw during production. When these modifications
affect servicing and/or spare parts, separate service
information will be sent out on each occasion. This means
that in time this Workshop manual will become out of
date. In order to prevent this, the Manual should be read
together with all service information issued concerning
the chainsaw in question.
Tools
Special tools must be used during specific steps. All service
tools are listed in the Workshop Manual. Usage is evident
from respective sections.
Always use Husqvarna original parts:
• Spare parts
• Service tools
• Accessories
