General recommendations
Bear in mind:
Do not start the engine without the clutch drum and
driveline
fi tted as the clutch can become detached and
cause severe personal injury.
Do not touch hot components, e.g. the muf fl er and clutch
before they have cooled suf fi ciently to avoid burns.
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 poiso-
nous!
Wipe up oil spills from the fl oor immediately to avoid slip-
ping.
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 ef fi ciently.
Special tools
Some of the work described in the Workshop Manual requires
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 ef
fi 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.
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 instruc-
tions are not followed.
The machine is type approved for safety in accordance with
applicable legislative demands with the equipment speci
fi ed
in the Operator’s Manual. The assembly of other equipment
or accessories 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.
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.
Fire risk
Handle fuel with respect as it is extremely in fl ammable.
Do not smoke and ensure there are no open fl ames or sparks
in the vicinity.
Make sure there is a working fi re extinguisher close at hand.
Do not try to extinguish a petrol fi re with water.
