Cooling System Safety

•
Swallowing engine coolant can cause poisoning;
keep out of reach from children and pets.
•
Discharge of hot, pressurized coolant or touching
a hot radiator and surrounding parts can cause
severe burns.
– Always allow the engine to cool at least 15
minutes before removing the radiator cap.
– Use a rag when opening the radiator cap, and
open the cap slowly to allow steam to escape.
•
Do not operate the machine without the covers
in place.
•
Keep your fingers, hands and clothing clear of
rotating fan and drive belt.
•
Shut off the engine and remove the key before
performing maintenance.
Cleaning the
Engine-Cooling Areas
Service Interval: Every 100 hours Clean the cooling
system twice as often during
special operating conditions; refer
to Maintaining the Machine under
Special Operating Conditions (page
28).
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
Important:
Brakes are a critical safety component
of the machine. Closely inspect them at the
recommended service interval to ensure optimum
performance and safety.
•
Inspect the brake lining for wear or damage. If the
lining (brake pad) thickness is less than 1.6 mm
(1/16 inch), replace the brake lining.
•
Inspect the backing plate and other components
for signs of excessive wear or deformation.
Replace any deformed components.
•
Check the brake-fluid level; refer to
