Servicing the Engine Cooling
System
Service Interval: Every 100 hours
Every 2 years
Remove debris from the oil radiator/oil cooler 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
radiator/oil cooler and screen debris build-up. While this
feature can help reduce the time required to clean radiator/oil
cooler, it does not eliminate the need for routine cleaning.
Periodic cleaning and inspection of the radiator/oil cooler is
still required.
1. Turn the engine off and raise the hood. Clean the
engine area thoroughly of all debris.
2. Clean both sides of the radiator/oil cooler area (Figure
67) 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/oil cooler
with water can promote premature corrosion and
damage to components.

Brake Maintenance
Adjusting the Service Brakes
Adjust the service brakes when there is more than 25 mm (1
inch) of "free travel" of the brake pedal, or when the brakes
do not work effectively. Free travel is the distance the brake
pedal moves before braking resistance is felt.
1. Disengage the locking latch from the brake pedals so
that both pedals work independently of each other.
2. To reduce free travel of the brake pedals, tighten the
brakes:
A. Loosen the 2 mounting screws and remove the
brake adjustment cover (Figure 68).

B. Loosen the front nut on the threaded end of the
brake cable (Figure 69).
