2.9.1. Machine operation during running-in
When putting a new machine into operation, the machine
should not be run at full power for the first 50 hours (driving
uphill with vibration).
2.9.2. Machine operation at low temperatures
Compacting in winter season depends on the content of fine
particles and water in the soil being compacted. With the tem-
perature declining below freezing point the soil becomes more
solid and harder to compact.
It necessary to compact at the temperatures below 0 °C (32 °F)
then it is possible to compact dry soil (and stony loose materials)
or make swift compaction of non-frozen materials (before earth
freezes through).
Preparation for work under low temperatures:
• Check concentration of the engine coolant.
• Exchange the engine oil with oil recommended for the
range of outside temperatures.
• Use hydraulic oil of the corresponding cinematic viscosity.
• Use winter fuel.
• Check the batteries are recharged.
The good condition of the battery is a precondition for good
starting under low temperatures. The machine can be used at
full power only after the fillings have been heated up to their
operating temperatures.
Min. temperature of engine coolant is 60 °C (140 °F). Max.
temperature of 100 °C (212 °F).
At temperatures below -13 °C (9 °F), replace the oil in the
hydraulic system with VG 32 class hydraulic oil.
Starting of the machine at temperatures below -23 °C
(-9 °F) is not possible without preheating of the operat-
ing fluids.
