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.
1. Unlatch and swing open the rear screen
Note: To remove the screen, lift it off the hinge pins.
2. Clean the screen thoroughly of all debris.
1. Rear-screen latch
3. Thoroughly clean both sides of the oil cooler and the
radiator with compressed air
Note: Start from the front and blow the debris out
toward the back. Then clean from the back side and
blow toward the front. Repeat procedure several times
until you remove all chaff and debris.
