Check the oil before each use and change the oil regularly (see Figures 1-1 through 1-5). Failure to use the correct oil, or using dirty oil, can cause premature engine wear and failure.

Forced air from the flywheel fan flows through the oil cooler fins dis- sipating heat from the engine oil (see Figure 8-5) . The oil cooler fins should be cleaned every 100 hours (or more often under dusty conditions) and checked periodically for debris.
