WARNING
Please make sure you read the technical documentation, such as the
Operator‘s Manual and workshop information, before carrying out
any maintenance work.
The composition of exhaust emissions is in
fluenced not only by the special emission
control equipment, but also by various
engine components and their adjustments.
Therefore, emission system maintenance
must include these engine components.
Some maintenance jobs are actually only
tests. They are important however, because
they allow early detection of discrepancies
which can later lead to increased exhaust
emissions. It is generally less expensive to
have such items adjusted immediately
rather than allowing them to contribute to
costly repairs. The maintenance intervals
have been determined so that the vehicle,
under normal conditions, should operate
properly between services.
Change the engine oil and oil filter every
10,000 miles or 1 year. If oil consumption
should increase, determine the cause and
take necessary corrective steps. Do not
reset the Maintenance System service
indicator if the oil level is adjusted or
changed outside the interval of
10,000 miles or 1 year.
Under normal dust conditions, replace the
air filter at every 20,000 miles or 2 years.
Clean air filter cover and housing prior to
removal of air filter.
Spark plugs are subject to electrode
erosion and must be replaced according to
the specified maintenance intervals, or
more frequently as may be required when
subject to severe operating conditions.
i
Maintenance services should be
performed at the number of miles or
years (whichever comes first) as
indicated.

service can be found starting on
