This LUBRICATION AND MAINTENANCE SCHEDULE lists those items commonly ordered on this engine which require servicing. The time intervals are based upon the numbers showing on the engine's service meter. Use the daily readings of the Service Meter to determine maintenance intervals. Perform required maintenance at multiples of each unit. "EVERY 10" means perform that maintenance at 10, 20, 30, etc., service meter units. For those areas which require periodic maintenance which cannot be given a definite service hour, see the column "WHEN TO SERVICE". For items marked (*) see "KEY TO FUELS, LUBRICANTS AND WATER" in this chart. "Page" refers to the page number in the LUBRICATION AND MAINTENANCE PROCEDURES where the service procedure is detailed for that item.
