Cleaning the Cooling
System
Service Interval: Before each use or daily—Remove
debris from the engine area, oil
cooler, and radiator.
Clean them more frequently in dirty conditions.
This machine is equipped with a hydraulically driven
fan drive system that automatically (or manually)
reverses to reduce oil cooler/radiator and screen
debris buildup. While this feature can help reduce
the time required to clean oil cooler/radiator, it does
not eliminate the need for routine cleaning. Periodic
cleaning and inspection of the radiator/cooler is still
required.
