The air intake area must be clear of debris to prevent
the engine from overheating.

decrease cooling performance.

remove all foreign material.

to "EVERY 100 HOURS" in "PERIODIC SERVICE"
section.
4. If the scale forms in the tube, clean with the scale
inhibitor or its equivalent.
5. Each time the panel screen is covered with grass
during operation, rub it off the screen with the hand.
Check the radiator screen from time to time if grass
accumulates.

panel, remove the radiator screen and clean inside
completely.
After cleaning, replace the radiator screens properly.

When assembling the panel screen, be sure to fit it in
the runners.
