The air cleaner consists of a plastic cover
with replaceable paper insert. The insert
should
be replaced every 40 000 km

dusty conditions, it may be necessary to
change the cleaner more often. No kind of
cleaning whatsoever should be carried out
between the above intervals.
To replace, disconnect the hose clamp for
the air preheating unit and also the clips
holding the air cleaner cover. The insert is
then accessible for removal. Make sure
when fitting the top section that the ther-

The air cleaner consists of a container
with a replaceable paper insert. The insert
should be replaced after every 40 000 km
