(1) Lubrication schedule

Time schedules indicated on the Lubrication Chart, Figure 1, are approximate. They are based on
average operating conditions. It may be necessary to lubricate more frequently under severe oper-
ating conditions such as: low engine temperature, high oil temperature, intermittent operation, or
dusty conditions. However, time intervals should not exceed those indicated in the chart without
careful evaluation.
The use of quality lubricating oil, combined with proper oil drain and filter change intervals are im-
portant factors in extending engine life.
