Cleaning the Radiator
Service Interval: Before each use or daily
Every 1,500 hours
Every 200 hours
Every 2 years
To prevent the engine from overheating, the radiator
must be kept clean. Normally, check the radiator daily
and, if necessary, clean any debris off these parts.
However, it will be necessary to check and clean
the radiator frequently in extremely dusty and dirty
conditions.
Note: If the mower deck or engine shuts off due to
overheating, first check the radiator for excessive buildup
of debris.
Clean the radiator as follows:
1. Open the hood.
2. Working from the fan side of the radiator, blow out
debris with low pressure (50 psi) compressed air (do
not use water). Repeat the step from the front of
the radiator and again from the fan side.

3. After the radiator is thoroughly cleaned, clean out
debris that may have collected in the channel at the
radiator base.
4. Close the hood.
