3.5 Operating Conditions Engine Operation
3.5.1 Winter Operation
● Lube Oil Viscosity
– Select the oil viscosity (SAE grade)
according to the ambient temperature when
the engine is started (see 4.1.2).
– Increase oil change frequency when operat-
ing below –10°C, see 6.1.1.
● Diesel Fuel
– Use winter-grade diesel fuel for operation
below 0°C, see 4.2.2.
● Coolant
–
Set the water/antifreeze mix to suit the lowest
likely temperature (max. –35°C), see 4.3.1.
● Additional Maintenance Work
– Drain the sludge from the fuel tank once a
week by undoing the drain plug.
– Adjust the oil level in the oil bath air cleaner
(if fitted) to suit the ambient temperature.
– At temperatures below –20°C, lubricate the
flywheel ring gear from time to time with
low-temperature grease, such as Bosch FT 1
V 31. To do so, remove the starter and
introduce the grease through the pinion hole.
● Cold-Start Aids
– At temperatures near or below freezing point,
use glow plugs if necessary (see 3.2.1).
This not only lowers the starting limit
temperature, but provides easier starting at
temperatures normally not requiring a
starting aid.
● Battery
– Efficient cold starting requires a healthy
battery (see 6.7.1).
– The starting limit temperature can be
lowered by 4-5°C by heating the battery up to
about +20°C. To do so, remove the battery
and store in a warm place.
