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 first 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 specified
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.
Bear in mind:
Do not start the engine without the clutch drum and
driveline fitted as the clutch can become detached and
cause severe personal injury.
Do not touch hot components, e.g. the muffler and
clutch before they have cooled sufficiently 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
poisonous!
Wipe up oil spills from the floor immediately to avoid
slipping.
Do not use tools that are worn or fit badly, for example
on nuts and bolts.
+ Always work on a clean bench.
+ Always work logically to ensure all parts are fitted
correctly and that nuts and bolts are tightened.
+ Use the special tools where recommended to be able to
carry out the work correctly and efficiently.
Fire risk
Handle fuel with respect as it is extremely inflammable.
Do not smoke and ensure there are no open flames or
sparks in the vicinity.
Make sure there is a working fire extinguisher close at hand.
Do not try to extinguish a petrol fire with water.

Poisonous fumes
When using cleaning agents read the instructions carefully.
Ensure there is good ventilation when handling petrol and
other volatile fluids.
The engine's exhaust fumes are poisonous. Test run the
engine outdoors.
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
expensive damage to parts in question and personal injury
and to provide an efficient 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 remo-
ved using a flat fine cut file.
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 fitted 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.
