81AP 240
OPERATION MANUAL
2.9.4. Machine work under high temperatures
and humidity
Engine power lowers with growing air temperature and humid-
ity.
Every 10 °C of temperature increase means power drop by
•
up to 4 % (at constant humidity),
Every 10 % of increased relative humidity means power drop
•
by up to 2 % (at constant temperature).
Note
In the environment where hydraulic oil temperature moves
•
constantly round 90 °C (194 °F), we recommend to have hyd-
raulic oil replaced by the oil with HV 100 kinematic viscosi-
ty.
For planetary gearbox with hydraulic torque converter wi-
•
thin the environment characterized as TROPICAL, we recom-
mend to use oil of SAE 30 viscosity value that corresponds to
the performance classication of Caterpillar TO-4.
2.9.5. Machine work in high altitudes
With altitude growing the atmospheric pressure and speci- •
c gravity of intake air decrease, and in connection therewi-
th the engine performance lowers.
If engine smokes black in the altitudes of over 1500 m, ple-
•
ase contact service department of engine manufacturer
(Engine Operation and Maintenance Manual) and this ma-
nufacturer will adjust the injection pump accordingly to suit
such conditions.
2.9.6. Work of the machine in the dusty
environment
When working in a very dusty environment, please cut short •
the intervals for replacement of suction lter elements, cut
short the interval for cleaning the coolers, for replacement
of cabin’s dust lter, refer to Machine Maintenance Table.
The engine power is aected by the
environment in which the machine is
working.
The machine may be used up to a maxi-
mum altitude of 3,658 m (12,000 ft).
