2.9.3. Using the machine under heavy
weather conditions
2.9.3.1. Operating the machine under low
temperature
Compacting in winter depends on content of fine particles
and water in compacted soil. The lower temperature
below zero, the firmer soil and more difficult compacting.
If it is necessary to compact at temperatures below 0 °C
(32 °F), dry soil can be compacted (and stone aggregates)
or non-frozen material must be compacted quickly before
it will freeze.
Prepare the machine for operation under low tempera-
ture:
• Check concentration of engine cooling liquid.
• Exchange engine oil for oil recommended for the
specific range of low ambient temperatures.
• Use hydraulic oil of appropriate kinematic viscosity.
• Exchange oil in drum and wheel gearbox for recom-
mended oil for the specific gearbox operating tempe-
rature range.
• Use winter fuel.
• Check battery charge.
Good battery condition is essential for good starting under
low temperature. You can lower the threshold starting
temperature to 4 to 5 °C (39.2 to 41 °F) by warming
batteries to approx. 20 °C (68 °F) (take them out and store
them in a heated room).
Minimum temperature of engine cooling liquid is 60 °C
(140 °F).
Use the machine at full power only after warming of
service fluids to the operating temperature (you can help
it by partially covering the radiator).
! NOTE !
If oil HV 100 is filled in the hydraulic system, the
machine must not be started at ambient temperatu-
re lower than +2 °C (36 °F).
If it is necessary to start the machine for a month
or longer at ambient temperature lower than -8 °C
(18 °F), exchange oil in hydraulic system for oil of
HV 46 viscosity grade.
At temperatures below -13 °C (9 °F), use HV 32 oil
(e.g. BP BARTRAN HV 32, ESSO UNIVIS N 32, etc.).
The machine cannot be started at temperatures
below -23 °C (-9 °F) without pre-heating service
fluids.
