Operation
57
Using the display selector switch (1) you can switch between the
engine speed and the hours of operation.
The time meter (display indication below) shows the actual
hours of operation of the excavator (independent from the en-
gine speed).
The speed indicator (display indication below) shows the current
engine speed.
Check the displays and indicators during operation (page 57).
Stopping the engine
Make sure idle speed is set when stopping the engine. When stopping the engine with a higher
speed, the turbocharger may get damaged due to insufficient lubrication.
If the engine is to be stopped to take the excavator out of operation, the services for placing the
excavator out of operation (page 70) must be carried out.

Turn the starter switch to the STOP position and remove the key.
Observation of the displays after starting and during operation
The operator must observe the indicators and displays after starting and during operation.
If the "Engine oil" message appears during operation, stop the engine immediately and contact skilled person-
nel.
If the "Charge" message appears during operation, stop the engine immediately. Check if the V-belt is very
loose or broken; if necessary, contact skilled personnel.
Watch the coolant temperature gauge, the bar should be inside the "A" range.
If the bar rises towards the "H" during excavator operation, stop the engine immediately and check the
coolant level in the expansion reservoir. Do not open the radiator cap
→
risk of scalding. If the water
level is below the "LOW" mark, allow the engine to cool completely and add coolant (page 96).
Check the cooling system for leaks; if necessary, contact skilled personnel.
Check if the V-belt is very loose or broken; if necessary, contact skilled personnel.
