CLEANING INTAKE SCREEN:

Grass particles, chaff or dirt can clog the air cooling system,
especially after prolonged service in cutting dry grass or when
operating in extremely dusty or dirty conditions. Continued
operation with a clogged cooling system can cause severe over-
heating and possible engine damage. Figure 1-6 shows the areas
to be cleaned. This should be a regular maintenance operation,
or clean intake screen and oil cooler fins after each use.
