Remember:
Never start the engine without the clutch and clutch drum
mounted.
Do not grasp hot elements such as the muffler or the clutch
before they have cooled sufficiently 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 floor immediately in order to
avoid injuries from slipping.
Do not use tools that are worn or fit 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.
Fire risk
Handle petrol with respect, since it is highly flammable.
Do not smoke and ensure that there are no open flames or
sparks in the vicinity.
Make sure that there is a functioning fire extinguisher in the
vicinity.
Do not try to extinguish a petrol fire with water.
Poisonous fumes
When using cleaning fluids, read the instructions carefully.
Make sure that ventilation is good when handling petrol, trichlo-
roethylene and other highly volatile liquids.
The engine exhaust is poisonous. Test run the engine only if
ventilation is good. Preferably outside.
Special tools
Certain tasks in this handbook require the use of special
tools. In sections where this is applicable, an image of the
tool with an ordering number is provided.
We recommend using special tools in order to avoid personal
injury and to eliminate expensive damage to the components
in question.
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 fine, float-cut file.
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.
WARNING!
Risk of personal injury if the instructions are not
followed.
NOTE!
Material damage may occur if the instructions are
not followed.
