General recommendations
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 poison-
ous!
● 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.
