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 aggre-
gates) or non-frozen material must be compacted quickly
before it will freeze.
Prepare the machine for operation under low temper-
ature:
•
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 temper-
ature 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 temperature lower than +2 °C
(36 °F).
If it is necessary to start the machine for
a month or longer at ambient tempera-
ture 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 tem-
peratures below -23 °C (-9 °F) without
pre-heating service fluids.
