2.9. Special conditions of the Machine use
2.9.5. Operating the Machine at high altitudes
With higher altitudes the engine capacity will drop due to re-
duced atmospheric pressure and specific weight of air induced.
If the engine has black smoke at high altitudes (over 1500 m),
please contact engine Manufacturer’s service centre who will
make adjustment to your fuel injection pump for these operat-
ing conditions.
2.9.6. Work of the machine in the dusty
environment
When operating in very dusty environment, you must cut short
the intervals for cleaning and replacement. Cut the intervals of
cleaning the engine cooler, hydraulics, and also of the replace-
ment of cab’s dust filter.
The engine power is affected by the envi-
ronment in which the machine is working.
The machine may be used up to a maxi-
mum altitude of 3,658 m (12,000 ft).
2.9.7. Driving with vibrations on compacted
and hard materials
When operating the Machine with vibration on hard materials
(e.g. stony loose material), or with high level of compacting the
base material, there can be even loss of contact between the
drum and the material compacted (so called vibro-hit). This state
will show in the increased vibration transfer into the Machine
frame and onto the Driver’s control stand. Its partial elimination
is possible via increasing the travel speed or changing the Ma-
chine vibration parameters (with the use of lower amplitude).
When it is necessary to operate the Machine under conditions
where the Operator might be exposed to higher vibrations, then
the Machine Operator will be liable to adjust the work proce-
dures so as to prevent any injury to Driver’s health.
Note
When driving the Machine with vibrations on a different base
material than stated in “Specification Manual”, the emission fig-
ures for vibration acceleration will be different - “Noise and vi-
bration emissions”.
The driving with vibration on hard (fro-
zen, concrete, overcompacted) surface or
on bedrock is forbidden. There is a danger
of damage to the machine.
