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.
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.
Target group
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.
Updates
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.
Tools
For specific procedures special tools are re- quired. In this workshop manual, all the service tools required are listed. Use of the tools is described in appropriate sections.
Always use Husqvarna original:
•Spare parts
•Service tools
•Accessories
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.
