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.
