2.9. Machine work under heavy conditions
2.9.2. Machine operation during its running-in
period
Upon the commencement of the operation of a new machi-
ne and during the rst 30 hours of operation, do not load
the machine at its full capacity.
2.9.3. Machine operation at low temperatures
The compaction in the winter period depends on the content of
ne particles and water in the compacted soil. The soil becomes
more solid and more dicult to compact with a decreasing tem-
perature below the freezing point.
Dry soils and stony soils can be compacted and non-frozen ma-
terials (before the soil freezes up) can be quickly compacted at
temperatures below 0 °C (32 °F).
Preparation for works at low temperatures
Check the concentration of the engine cooling liquid.
•
Exchange the engine oil with the recommended one for the
•
respective low ambient temperatures.
Use the hydraulic oil of the corresponding kinematic visco-
•
sity.
Use the winter fuel.
•
Check the battery charge.
•
Note
Heating the batteries to approximately 20 °C (68 °F) (by remov-
ing and storing the batteries in a warm room) will reduce the
limiting starting temperature by 4 to 5 °C (39.2 to 41 °F).
The minimum temperature of the engine cooling liquid is 60 °C
(140 °F). The maximum temperature is 100 °C (212 °F).
! CAUTION !
When using the HV 100 oil in the hydraulic system,
the machine must not be started at ambient tempe-
ratures below +2 °C (36 °F).
