4 Putting into operation
Starting the engine at low ambient temperatures
Start the engine as described in chapter Starting the engine.
Warm-up phase at low ambient temperatures
• Let the engine run below 1800 rpm until the coolant reaches its
operating temperature.
• Avoid fast movements of the operating hydraulics.
• Check for unusual noise, exhaust color, leaks, malfunctions or
damage.
In case of malfunctions, damage, or leaks:
Secure the vehicle, park it and find out the cause for the damage and
have it repaired.
Notices on the warm-up phase
• After reaching the operating temperature, the engine can be operated
under full load.
• The engine reaches its operating temperature more quickly at low
engine speed and under load. This is more efficient than operation at
low engine speed without any load.
• Avoid excess idling. This causes carbon deposits or an increased soot
load of the diesel particulate filter, for example.
Crushing hazard during operation with cold hydraulic oil!
Cold hydraulic oil can cause uncontrolled machine movements. This can
cause serious injury or death.
► The hydraulic oil is still cold even if the engine has reached its
operating temperature.
► If possible, run the machine warm on wide and open terrain.
► Operate the control lever especially carefully if the hydraulic oil is cold.
