Checking and Cleaning Radiator to Prevent Overheating
CAUTION
To avoid personal injury:
• Be sure to stop the engine and remove the key before
cleaning.
Daily or after every 5 hours of operation, check to be sure the
radiator screen and radiator core are clean. Dirt or chaff on the
radiator screen or radiator core decrease cooling performance.
1. Remove the radiator screen and panel screen and remove all
foreign material.
2. Remove the dust from between the fins and the tube.
3. Tighten the fan drive belt as necessary. For this, refer to “EVERY
100 HOURS” in Maintenance section.
4. If 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 hand. Check the radiator
screen from time to time if grass accumulates.
6. If the dust or chaff has accumulated inside of the panel, remove
the radiator screen and clean inside completely.
After cleaning, replace the radiator screens properly.
NOTE
• When assembling the panel screen, be sure to fit it in the
runners.
