8.2.5 Shutting down the machine
CAUTION
Thermal overload of the turbo charger.
Abrupt stopping of the engine under load can cause a fault or damage to the turbo charger.
➤ Run the engine a few minutes in idle before shutting down to allow the turbo charger to cool.
Operating the machine in the cool-down phase
➤ Press and hold the «Stop» key for longer than one second.
■ The machine switches to unloaded run-on, i.e. the engine runs at IDLE speed and the oil
separator tank is vented.
■ When the cool-down period has elapsed (engine setting "unloaded run-on") the machine has
cooled enough so that the engine can stop automatically.
■ The controller display shows
back pressure if the pressure in the oil separator tank is still
> 1 bar.
■ When the machine is fully vented, the display changes to
ready to start.
■ When the OST is fully vented after shutdown, the re-start inhibitor is activated and is indi‐
cated by the timer counting down from 20 seconds.
Shutting down the machine
If the machine is not to be used again, the «battery isolating switch» should be switched off.
