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.
Periodic cleaning and inspection of the radiator/oil cooler is
still required.
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.

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 you feel braking resistance.
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 as follows:
A. Loosen the 2 mounting screws and remove the
brake-adjustment cover

B. Loosen the front nut on the threaded end of the
brake cable (Figure
(Figure 67).
