6 - WORKING OPERATIONS
Operating the machine in hot weather and high altitudes
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 behaviour, are impaired.
Engine can be used at altitudes up to 3000 m ( 9842.5 ft )
and temperatures up to 50 °C ( 122.0 °F ) for mobile oper-
ations.
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 reser-
voir;
• check the condition of the cooler plug before starting
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 viscos-
ity;
• use an appropriate coolant.
