OPERATION
2.2.7 Operation monitoring
Observe the control and indication instruments
on the dashboard from time to time.
If an illuminated indicator or the Diagnostic
Code indicator indicates a malfunction, find out
and eliminate the cause.
If an acoustic signal sounds, immediately shut
down the engine.
Check the filling level for operating substances
(fuel, water, additive). Fill up tanks in time.
Never drive the machine until the fuel tank is
empty.
The alternator is driven by a drive belt. If the
drive belt tears, the battery charging current is
interrupted. The illuminated indicator for charg-
ing current (201) lights up. Switch off the en-
gine immediately to prevent battery discharge.
Replace defect drive belt by a new one.
Observe the following items in order to main-
tain a proper function of the alternator:
• Do not interrupt the connection between
battery and alternator when the engine is
running.
• Do not confuse battery connections.
• Remove the earthing strip from the battery
strip during welding work.
In order to protect electronic components as e.
g. central control unit, monitor unit, sensors, re-
lays etc., all connectors must be pulled out pri-
or to welding work; otherwise, the electronic
components will be destroyed. The negative
pole must be applied directly to the construc-
tive part to be welded. Take care for a good
contact!
