NOTE: 500 and 1000 hour intervals are meant to be repeated at
every 500 or 1000 hours. Other intervals only to be performed at
hours indicated.
NOTE: All fluid and filter intervals are valid for near perfect conditions
only. High ambient temperatures - high dust concentration - high
humidity as well as using lower grade oils and fuels will require a
decrease in maintenance intervals.
Contact your Doosan Infracore Portable Power dealer for more
information or assistance in determining the optimum intervals for
your application.
