Maintenance
The maintenance programme covers a number of
points that are divided into the following sec-
tions:
• Lubrication system.
• Air cleaner.
• Cooling system.
• Fuel system.
• Miscellaneous.
Secure the starting device or disconnect a battery
cable before working on the engine. If the engine
starts unexpectedly, there is a serious risk of in-
jury.
There is always a risk of sustaining burns when
an engine is hot. Particularly hot parts are branch
pipes, turbochargers, oil sumps, and hot coolant
and oil in pipes and hoses.
The maintenance programme includes the fol-
lowing:
• R maintenance: One event when taken into
service.
• S maintenance: Minimum basic maintenance.
• M maintenance: More extensive mainte-
nance.
• L maintenance: Includes nearly all mainte-
nance items in the form.
• XL maintenance: Includes all maintenance
items in the form.
During a period, the sequence is S-M-S-L-S-M-
S-L-S-M-S-XL.
