Operating the machine in high altitude
Air density decreases as altitude or ambient temperature
increases.
As a result of this, the engine's maximum output, quality
of exhaust gas, temperature level and, in extreme cases,
starting behavior, are impaired.
Engine can be used at altitudes up to 3000 m (9842 ft) and
temperatures up to 50 °C (122 °F) for mobile operations.
If the engine is to operate under more severe conditions
(at higher altitudes or temperatures), it will be necessary
to reduce the injected fuel quantity with the resulting loss
of engine power.
Observe the following recommendations:
Maintain the correct coolant level in the coolant
•
reservoir.
Check the condition of the cooler plug before start-
•
ing and replace it if necessary.
Carefully clean the cooler and the engine.
•
Check the condition of the alternator belt and engine
•
fan belt.
Use lubricants with the recommended degree of vis-
•
cosity.
Use an appropriate coolant.
