Servicing the
Engine-Cooling System
Service Interval: Every 100 hours
Every 2 years
This machine is equipped with a hydraulically driven
fan-drive system that automatically (or manually)
reverses to reduce the radiator/oil cooler and screen
debris buildup. While this feature can help reduce the
time required to clean radiator/oil cooler, it does not
eliminate the need for routine cleaning.
1. Shut off the engine and raise the hood.
2. Clean the engine area thoroughly of all debris.
3. Clean both sides of the radiator/oil cooler area
thoroughly with compressed air
Note:
Start from the fan side and blow the
debris out toward the back. Then, clean from
the back side and blow toward the front. Repeat
this procedure several times until all chaff and
debris is removed.
Important:
Cleaning the radiator/oil cooler
with water can promote premature corrosion
and damage to components.
