Cooling System
Maintenance
Cleaning the
Engine-Cooling Areas
Service Interval:
Every 100 hours Clean the cooling
system twice as often during
special operating conditions; refer
to
Special Operating Conditions (page
27)
.
Important:
Operating the engine with a blocked
rotating screen, dirty or plugged cooling fins, or
with the cooling shrouds removed, causes engine
damage due to overheating.
Important:
Never clean the engine with a pressure
washer because water could contaminate the fuel
system.
Clean the rotating screen, cooling fins, and external
surfaces of the engine.
Note:
Clean the engine cooling components more
often under extremely dusty and dirty conditions.
Brake Maintenance
Inspecting the Brakes
Service Interval:
Every 100 hours
Brakes are a critical safety component of the machine.
As with all safety components, they should be closely
inspected at regular intervals to ensure optimum
performance and safety.
•
Inspect the brake shoes and pads for wear or
damage. If the lining (brake pad) thickness is less
than 1.6 mm (1/16 inch), the brake shoes should
be replaced.
•
Inspect the backing plate and other components
for signs of excessive wear or deformation. If any
deformation is found, the appropriate components
must be replaced.
•
Check the brake-fluid level; refer to
Brake-Fluid Level (page 52)
.
