CAUTION
Extending the oil and filter change in-
terval beyond the recommendations
will decrease the engine life due to
factors such as corrosion, deposits,
and wear. Engine oil filters capture dirt
and remove deposits from the oil to
prolong the life of internal moving com-
ponents. Follow the oil and filter
change intervals as recommended in
this section of the manual. Failure to
comply may result in equipment or
property damage.
