INSTRUMENTS AND CONTROLS
2 - ENGINE COOLANT TEMPERATURE INDICA-
TOR
3 - FUEL LEVEL INDICATOR
This instrument indicates the temperature of the engine coolant,
which in normal conditions should be 80-85°C.
After starting the engine and before starting work, let it warm up
until the temperature indicator reaches the green range.
If the indicator exceeds the limit values while the engine is run-
ning and reaches the overheating red range, let the engine idle
until the indicator returns to the normal temperature green range.
When the indicator reaches the overheating red range, the acous-
tic alarm sounds, too.
If this inconvenience occurs repeatedly, try to find out the cause
(see “3.14.4.3 TROUBLESHOOTING – ENGINE”).

is available only with the ignition key in position «I» (see “3.3.3

The green range indicates the normal fuel level, while the red
range indicates that the fuel level is low.

If the indicator reaches the reserve red range while the ma-
chine is working, stop it and refuel it up to the correct level.
