Operation in winter
Oil preheating*
Before starting the engine at temperatures below - 20 °C,
turn on the heating element* to preheat the oil.
- Connect the preheating system plug to a 230 VAC
outlet.
Observe the operating instructions of the manufacturer.
Winter diesel fuel
Whenever temperatures fall below 0°C, use winter diesel or
super diesel fuel or additives recommended in the mainte-
nance instructions.
Engine oil for winter operation
Fill engine oil with a suitable SAE class as recommended in
the maintenance instructions.
The cold start capability of the engine can be reduced if the
temperature limits are underrun occasionally, but this will not
damage the engine.
Hydraulic system
The hydraulic functions are sluggish and slower during cold
temperatures. Bring the hydraulic system to operating tem-
perature with some movements without a load.
Putting on snow chains
Snow chains can be mounted on the tires to improve grip.
In the following table you will find the order numbers for
RUD chains which fit on the listed tires. You can also fit
snow chains from other manufacturers if these have the
proper dimensions.
Ballasting
The weight of the machine can be increased with ballast
weights. The ballast weights must be applied parallel with
the same weight on each axle and side.
