The service meter is the most reliable method of determining service intervals. The service meter shows the total
number of units your engine has run. Perform the maintenance at multiple intervals of units shown. For example when
the service meter shows "100" on the dial, all items listed under "EVERY 10 SERVICE METER UNITS" should be
serviced now for the tenth time, and all items under "EVERY 50 SERVICE METER UNITS" should be serviced for the
If your engine does not have a service meter, use the calendar interval. These figures are based on a 10 hour day
and a 2000 hour year. If your operation differs from these limits, base your service intervals on actual running time.
Keep an accurate record of operating time.
Items which do not pertain to your engine may be lined out to customize your charts.
