Servicing the Engine Cooling
System
Service Interval: Before each use or daily
Remove debris from the engine area, oil cooler and
radiator daily. 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 build-up. 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.
1. Unlatch and swing open the rear screen
Clean the screen thoroughly of all debris.
Note: To remove screen, lift off hinge pins.

Repeat procedure several times until all chaff and
debris is removed.
