engine life.
2. PERIODIC INSPECTION
Periodic maintenance is vital to the safe and
efficient operation of your engine.
Check the table below for periodic maintenance
intervals.
Should the engine be operated in extremely dusty
condition or in heavier loading condition, the
maintenance intervals must be shortened
depending on the contamination of oil, clogging of
filter elements, wear of parts, and so on.
