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 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, remove the key, 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.

Release the locking latch from the brake pedals
so that both pedals work independently of each
other.
To reduce free travel of the brake pedals, tighten
the brakes as follows:
A. Loosen the front nut on the threaded end of
the brake cable (Figure
Figure 73
B. Tighten the rear nut to move the cable
rearward until the brake pedals have 13 to
25 mm (1/2 to 1 inch) of free travel.
C. Tighten the front nuts after the brakes are
adjusted correctly.
