Clean the cooling ribs
Attention!
Take care when cleaning the radiator with high-pressure
washers or steam blasters! The cooling ribs are composed of
metal plates which are 0.1 mm thick and can be easily
damaged.
Maintain a clearance of at least 30 cm between the nozzle
and radiator ribs!
A slow increase in the coolant and/or hydraulic oil temperature indicates
the cooling system is soiled.
If the coolant temperature is too high (over 110 °C), the corresponding
warning message appears in the multifunctional display.
When completing the work assigned, it may be sufficient to actuate the
reversible fan (option) at regular intervals by pressing the button
