Work lights (amber)

This warning light illuminates when the work lights are switched on.
Information Display
19
The display shows information on the operational condition of the machine and highlights any
trouble in the form of symbols or error codes.
Rev counter/ Techometer
The rev counter (1) indicates the engine rpm. Each di-
vision on the scale represents 100 rev/min., therefore,
with the needle indicating 20 , the engine is running at
2000 RPM.
Engine speed
NOTICE: Never use the engine continuously for a long
time at speeds between 2500 - 3000 RPM (yellow area
on the speedometer) to avoid damage to the engine
and definitely never exceed 3000 RPM (red area on
the speedometer). For appropriate use, always operate
under the speed corresponding to 2300 RPM.
Engine coolant temperature gauge
The temperature display (1) indicates the temperature of
the engine coolant.
• blue area = normal temperature;
• red area = temperature too high.
In this case, slow the engine to idling speed (without stop-
ping the engine) and, if the light stays on, have the cooling
system checked.
Fuel level gauge
This instrument (1) indicates the level of diesel in the tank
and only works when the ignition key is turned onto ON.
