INSTRUMENTS AND CONTROLS
2 - ENGINE COOLANT TEMPERATURE INDICA-
TOR
3 - FUEL LEVEL INDICATORT
It indicates the temperature of the engine coolant, which must
normally be 80-85°C.
After the start, it is necessary to let the engine warm up before
beginning work.
If during operation the indicator exceeds the limit values and en-
ters the overheating sector (red), let the engine idle until the indi-
cator returns to the normal temperature sector (green).
When the indicator is in the overheating sector (red), the acous-
tic alarm sounds, too.
If this inconvenience occurs again, try to locate the fault (see
3.15.5.3 TROUBLE-SHOOTING - ENGINE).
