OPERATING MANUAL
2.9.3 Machine operation during initial run
period
When putting anew machine into operation or during the rst
30 hours after acomplete overhaul, do not run the machine at
full power!
2.9.4 Machine operation at low
temperatures
The compaction in the winter season depends on the content
of ne particles and water in the soil being compacted. With
the temperature dropping below the freezing point the soil be-
comes more solid and harder to compact.
At the temperatures below 0°C (32°F) it is possible to compact
only dry soils (and loose stony materials), or carry out rapid com-
paction of non-frozen materials (before the soil gets frozen).
Prepare the machine for operation at low temperatures:
- Check concentration of the engine coolant.
- Replace the engine oil with the oil recommended for the
range of ambient temperatures.
- Use hydraulic oil of the corresponding cinematic viscos-
ity.
- Use awinter diesel.
- Check the battery for charging.
The good condition of the battery is aprecondition for good
starting under low temperatures. The machine can be used at
full power only after the operating uids have been heated to
their operating temperatures.
2.9.5 Machine operation at higher
temperatures and humidity
The engine power output decreases with the increasing tem-
perature and air humidity. Considering that both of the factors
reducing the engine power are independent on each other, it is
possible to describe their impact as follows:
- Every 10°C (18°F) of the temperature rise means apow-
er drop by up to 4% (at aconstant humidity);
- Every 10% of the relative humidity rise means apower
drop by up to 2% (at aconstant temperature).
At outdoor temperatures when the hydraulic oil temperature is
constantly about 90°C (194°F), we recommend you to replace
the oil with the oil ISO VG 100 having the cinematic viscosity of
100mm
2
/s at 40°C (104°F).
2.9.6 Machine operation at higher altitudes
With the increasing altitude, the engine power output decreas-
es as a result of the lower atmospheric pressure and specic
density of the incoming air.
The engine power depends on the environment, in which
the machine is working.
