2.9. Special conditions of the Machine use
2.9.2. 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).
2.9.3. 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 engine cooling liquid.
• Exchange oil in the engine with the recommended one for
given range of low ambient temperatures.
• Use hydraulic oil of corresponding cinematic viscosity.
• Oil in drum gearbox, replace with recommended one for gi-
ven operating temperature range of the gearbox.
• Use winter fuel.
• Check the batteries are recharged.
Note
Warm the batteries to ca 20 °C (68 °F) (removing the batteries
and storing them in a warn room) to lower the limit temperature
for starting by 4 to 5 °C (39,2 to 41 °F).
! CAUTION !
When using HV 100 oil in the hydraulic system
NEVER start the Machine at ambient temperatures
below +2 °C (36 °F).
If required to start the Machine for the period of one
month or longer at ambient temperatures below
-8 °C (18 °F), replace oil in hydraulic system with the
oil of HV 46 viscosity class.
At temperatures below -13 °C (9 °F) with oil of HV 32
class.
It is impossible to start the Machine below -23 °C
(-9 °C) with no preheating of filling media.
Min temperature of engine cooling liq-
uid is 60 °C (140 °F). Max temperature of
100 °C (212 °F).
You may use the Machine at its full capac-
ity only after heating the media to their
operating temperature (cooler possible
to be partially covered).
