Cleaning Radiator And Screen
To prevent the engine from overheating, the screen and
radiator must be kept clean. Normally, check the screen and
radiator daily and, if necessary, clean any debris off these
parts. However, it will be necessary to check and clean the
screen and radiator frequently in extremely dusty and dirty
conditions.
Note: If engine shuts off due to overheating, first check the
radiator and screen for excessive buildup of debris.
To thoroughly clean the radiator:
1. Remove the screen.
2. Working from the fan side of the radiator, either spray
the radiator with a water hose or blow with compressed
air.
3. After the radiator is thoroughly cleaned, clean out
debris that may have collected in the channel at the
radiator base.
4. Clean and install the screen.
