This machine is equipped with a hydraulically driven fan
drive system that automatically (or manually) reverses
to reduce radiator and screen debris build-up. While
this feature can help reduce the time required to clean
radiators and coolers, it does not eliminate the need for
routine cleaning. Periodic cleaning and inspection of
the radiator is still required.
Remove debris from the oil cooler and radiator
daily. Clean them more frequently in dirty conditions.
1. Turn the engine off and raise the hood. Clean the
engine area thoroughly of all debris.
2. Remove the knobs (Figure 61) securing the oil cooler
to the frame.
1. Knobs
3. Pivot the oil cooler rearward. Clean both sides of the
oil cooler and radiator area (Figure 62) thoroughly
with compressed air. Start from the fan side and
blow the debris out towards the back. Then clean
from the back side and blow towards the front.
Repeat procedure several times until all chaff and
debris is removed.
Important: Cleaning the radiator or oil cooler
with water can promote premature corrosion
and damage to components.
