FUNCTIONING
INSTRUMENTS AND CONTROLS
(2) Fuel level indicator
It indicates the fuel level in the tank and functions only when
the ignition key is in position "I" (see "Ignition switch (3-11)").
F: maximum level.
E: minimum level.
If the quantity of fuel in the tank is less than 6 litres, the
indicator reaches the red reserve area (A) and the warning light
(B) blinks.
REMARK
If the indicator reaches the red reserve area (A) during use,
stop the engine and provide for refuelling.
(3) Hour meter
This instrument indicates the total number of operating hours of
the engine. The count is continuous and the hour number is
increased by 0.1 when the engine has worked for 0.1 hour (6
minutes), independently of the engine speed.
The hour counter keeps counting even if the machine isn't
working or travelling.
Use this display to manage the specified service intervals.
