Servicing the Engine-Cooling
System
Service Interval: Every 100 hours—Inspect the
cooling-system hoses.
Every 2 years—Flush the cooling system and replace
fluid.
Before each use or daily (more often in dusty or dirty
conditions).
1. Shut off the engine and raise the hood.
2. Clean the engine area thoroughly of all debris.
3. Rotate the latches securing the oil cooler to the frame
(Figure 78).

1. Latches
4. Pivot the oil cooler rearward.
5. Clean both sides of the oil cooler and radiator area
thoroughly with compressed air.
Note: 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.
6. Pivot the oil cooler back into position.
7. Secure the oil cooler to the frame with the latches and
close the hood.

Brake Maintenance

Adjusting the Service Brakes

Adjust the service brakes when there is more than 50 mm (2
inches) 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 the free travel of the brake pedals, adjust
the brake cables as follows:
A. Loosen the front nut on the threaded end of the
brake cable.
Note: For easier access to the adjusting nuts, you
may unhook and remove the spring.

2. Front nut
B. Tighten the rear nut until the brake pedals have
50 mm (2 inches) of free travel.
C. Repeat the procedure on the other brake cable.
D. Tighten the front nuts after adjusting the brakes.
E. Install the springs, if removed.
Important: Adjusting the brake tension too tight
decreases the life of the friction-pad material.
