TIPS AND MAINTENANCE
Running-in
During the first few operating hours the
engine internal friction is higher than
later on when all the moving parts have
bedded down. How well this running-in
process is done depends to a consider-
able extent on the way the vehicle is dri-
ven during the first 1500 km.
Up to 1000 kilometres
the following general rules apply:
•
Do not use full throttle
•
Do not drive faster than 3/4 of top
speed
•
Avoid high engine speeds
•
Trailer towing should if possible be
avoided.
Warning
•
New tyres must also be “run in”
because they do not have maxi-
mum adhesion at the start. This
must be taken into account by
driving carefully during the first
100 km.
•
New brake linings must also be
run in and do not have the opti-
mum friction properties during the
first 200 km. The slightly reduced
braking effect can be compen-
sated for by more pressure on the
brake pedal. This also applies
when new linings have been fit-
ted.
From 1000 – 1500 km
The speed can be gradually increased to
the road or engine maximum.
During and after the running-in
period the following applies:
•
Do not overrev the engine when cold –
either in neutral or in the gears.
All speeds and revs given are only valid
when engine is properly warm.
❀
Do not drive with the engine
speed unnecessarily high –
changing up early helps to save fuel,
reduces noise and protects the envi-
ronment.
•
Do not let engine labour – change down
when engine no longer runs smoothly.
After the running-in period
•
On vehicles with a rev counter* the
maximum permissible engine speed is
shown by the beginning of the red zone
on the rev counter scale. The needle of the
counter must not move into this zone.
Extremely high engine revs will be auto-
matically governed.
