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 optimum operating values of a warm machine
are:
- engine: 60 - 110°C coolant temperature,
2.4 - 2.8 bar oil pressure at idle speed.
- hydraulic system: 45 - 85°C hydraulic oil
temperature.
The temperatures and pressure levels can be
called up from the info screen 2 and 3.
Before the milling procedure is started, all
hydraulic function elements on the machine
should be moved several times.
See main screen information from “Machine
description” section.
