General recommendations

The workshop used to carry out repairs must be equipped with
safety devices in accordance with local directives.
No one may carry out repairs without fi rst having read and
understood the contents of this Workshop Manual.
The boxes below can be found in appropriate parts of this manual.
WARNING!
The warning box warns of the risk for
personal injury if the instructions are not
followed.
NOTE!
This box warns of damage to material if the instructions
are not followed.
The machine is type approved for safety in accordance with
applicable legislative demands with the equipment specifi ed in
the Operator's Manual. The assembly of other equipment or ac-
cessories or spare parts not approved by Husqvarna can result
in the failure to meet these safety demands and that the person
carrying out assembly bears responsibility for this.
Bear in mind:
Do not start the machine without making sure the cut-
ting attachment and all the safety features are fi tted and
working properly.
To avoid burns, do not touch hot components, e.g. the
muffl er before they have cooled suffi ciently.
Avoid getting fuel or oil on your skin or in your mouth.
Use a barrier cream on your hands. This reduces the
risk of infection and makes dirt easier to wash away.
Long term contact with engine oil can represent a health
hazard.
Never start the engine indoors. Exhaust fumes are poi-
sonous! They contain carbon monoxide, an odourless,
poisonous and highly dangerous gas.
Wipe up oil spills from the fl oor immediately to avoid
slipping.
Do not use tools that are worn or fi t badly, for example
on nuts and bolts.
+
Always work on a clean bench.
+
Always work logically to ensure all parts are fi tted cor-
rectly and that nuts and bolts are tightened.
+
Use the special tools where recommended to be able
to carry out the work correctly and effi ciently.

Starter
Fire risk
Handle fuel with respect as it is extremely infl ammable.
Never refuel while the engine is running.
Do not smoke and ensure there are no open fl ames or sparks
in the vicinity.
Never start the engine if the machine is leaking fuel or if there
has been a spillage when refuelling. Allow the remaining fuel
to evaporate fi rst.
Make sure there is a working fi re extinguisher close at hand.
Do not try to extinguish a petrol fi re with water.
Poisonous fumes
When using cleaning agents read the instructions carefully.
Ensure there is good ventilation when handling petrol and other
volatile fl uids.
The engine's exhaust fumes are poisonous. Test run the engine
outdoors.
Special tools
Some of the work described in this workshop manual re-
quires special tools. In each section where this is necessary
there is a picture of the tool and an order number.
We recommend the use of special tools in order to avoid ex-
pensive damage to parts in question and personal injury and
to provide an effi cient repair procedure.
Contact faces and gaskets
Ensure all surfaces are clean and free from gasket residue,
etc. When cleaning use a tool that will not damage the contact
face. Any scratches or unevenness should be removed using
a fl at fi ne cut fi le.
Sealing rings
Always replace a sealing ring that has been dismantled. The
sensitive sealing lip can easily be damaged resulting in inferior
sealing capacity. Surfaces which the seal shall seal against
must also be completely undamaged. Lubricate the sealing lip
with grease before it is fi tted and ensure that it is not damaged
e.g. by shoulders and splines on a shaft. Use tape or a conical
sleeve as protection. It is important that the sealing ring faces
in the right direction for it to act as it is intended.
