General recommendations
Remember:
!
Never start the engine without the clutch and clutch drum
mounted.
!
Do not grasp hot elements such as the muffl er or the clutch
before they have cooled suffi ciently to avoid burn injuries.
!
Avoid getting petrol on you skin or in your mouth. Use
protective cream on your hands. This lowers the risk of
infection and makes dirt easier to wash off. Long-term contact
with engine oil can be damaging to your health.
!
Never run the engine indoors. The engine exhaust is poisonous!
!
Wipe up any spilled oil from the fl oor immediately in order to
avoid injuries from slipping.

Do not use tools that are worn or fi t poorly on nuts and bolts
and so on.
+ Always work on a clean work surface.
+ Always work in a logical manner in order to be sure that all
components are correctly attached and that nuts and bolts are
tightened.
+ Use special tools where recommended in order to work
correctly.

Sealing faces and gaskets
Make sure that all sealing faces are clean and free from old
gasket remnants. Use a tool that will not damage the sealing
face when it is cleaned. Any scratches and irregularities
should be removed with a fi ne, fl oat-cut fi le.
Sealing rings
Always change a sealing ring once it has been dismounted.
The sensitive sealing lips can be easily damaged with poor
sealing ability as a result. The surfaces that the seal is to
tighten against must also be completely free from damage.
Lubricate the sealing lip with grease before it is attached
and make sure that it is not damaged by such things as the
collars and splines on an axle. Use tape or a conical bushing
as protection. It is important that the sealing ring is turned
correctly in order for it to function as intended.
NOTE!
Material damage may occur if the instructions are not
followed.
