Allowing engine to „warm up“
To keep excessive wear and increased load of individual assemblies to a minimum,
the engine should always, but especially at low outside temperatures (<10°C), warm
up for approx. 5 minutes at idle speed and without any load.
The milling drum should be engaged.
The optimum operating values of a warm machine are:
- Coolant temperature of engine: >70°C
- Hydraulic oil temperature: 60-70°C
Take due note of visual signal from the
hydraulic system! If indicator light (A)
lights up, milling must be interrupted or
should not be started.
Check hydraulic oil filter for signs of dirt,
and also check the oil level.
Before the milling operation is started, all
hydraulic function elements on the ma-
chine should be moved several times.
