Operating in emergency situations
In case of emergency, you can switch off the engine and lower the boom manually.
Engine stop knob
If the engine cannot be stopped with the key, it can be stopped man-
ually.
To stop the engine, pull the knob (1) until the engine stops.
After the engine has stopped, push in the knob.
Manual lowering of the front attachments
The boom and arm can be lowered in case of an engine failure or if malfunctions occur in the hydraulic system.
Turn the starter switch to the RUN position.
If necessary, lower the boom and the arm with the control levers as described in the "Operating the controls
during excavation work" section (page 88).
The excavator may only be taken back into operation after the malfunction has been eliminated.
Make sure nobody is standing in the lowering area before starting the emergency lowering proce-
dure.
The lowering function is available only for a short time, as it is controlled by the accumulator in the
hydraulic system. The cylinders extend or retract by force of gravity.
