2.9.2. How to operate the Machine during its
running-in
Do NOT load the Machine at its full capacity when putting the
new Machine into operation or following its major overhaul dur-
ing the rst 30 hours!
2.9.3. Operating the Machine at low
temperatures
Compacting during winter season depends on the content of
ne particles and water in the soil being compacted. With the
temperature dropping below freezing point the soil becomes
more solid and harder to compact.
At the temperatures below 0 °C (32 °F) it is possible to compact
only dry soils (and stony loose materials), or carry out rapid com-
paction of non-frozen materials (before soil gets frozen).
Set up the Machine for operation at low temperatures:
Check concentration of engine cooling liquid.
•
Exchange motor oil for the one recommended for given ex-
•
ternal temperature range.
Use hydraulic oil of corresponding cinematic viscosity.
•
Use winter diesel oil.
•
Conrm battery has been recharged.
•
A precondition for proper starting at low temperatures is that
the battery is OK. The Machine can be used at its full capacity
only after the media have been heated to their operating tem-
peratures.
2.9.4. Machine operation at high temperatures
and humidity
The engine power lowers with the air temperature and moisture
increasing. Due to the fact that both these factors reducing the
engine power, are independent on each other, it is possible to
describe their impact as follows:
each 10 °C (18 °F) of temperature rise means power drop
-
by up to 4 % (at constant humidity)
each 10 % of RH increase means power drop by up to 2
-
% (at constant temperature).
At ambient temperatures when hydraulic oil temperature is
constantly round 90 °C (194 °F), we recommend to exchange oil
for the one with cinematic viscosity of 100 mm
2
/s.
2.9.5. Machine operation at high altitudes
With the altitudes increasing the engine power drops due to
lower atmospheric pressure and lower specic weight of intake
air.
While in very dusty environment, please
cut short the intervals of cleaning and
replacing the air lter elements; and the
replacement intervals of cabin dust l-
ter, and cut short the intervals of clean-
ing the coolers.
Recommended interval of cleaning is 1x
per week.
2.9.6. Machine operation within very dusty
environment
Engine power depends on the environ-
ment where the Machine is operating.
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
During Machine travel with vibration the drums may loose con-
tact with the materials being compacted (so called vibro-stroke)
due to high level of compaction of the background material or
travel with vibration on hard materials. This condition will come
to light in the form of increased vibration transfer into Machine
frame and onto operator’s control stand. The vibro-stroke can
partly be eliminated through the increased travel speed.
It is banned to work in vibro-stroke mode
in the long term!
In extreme cases there is Machine dam-
age hazard or operator’s health hazard!
