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.
Remove debris and chaff from the engine compartment,
oil cooler and radiator daily. Clean more frequently in
dusty and dirty conditions, if required.
1. Turn the engine off and raise the hood. Clean the
engine area thoroughly of all debris.
2. Rotate the latches (Figure
to the frame.

1. Latches
3. Pivot the oil cooler rearward. Clean both sides of the oil
cooler and radiator area 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 or oil cooler
with water can promote premature corrosion and
damage to components.
4. Pivot the oil cooler back into position. Secure it 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 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, adjust the
brake cables as follows:
A. Loosen the front nut on the threaded end of the
brake cable.
Note: To allow easier access to the adjusting
nuts, the spring may be unhooked and removed.

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 the brakes are adjusted
correctly.
E. Reinstall the springs, if removed.
Important: Adjusting the brake tension too tight
will decrease the life of the friction pad material.
