EXPLANATION OF COMPONENTS
FUEL GAUGE
Fuel gauge shows the amount of fuel in the fuel tank.
If the indicator is in red range (C), the fuel level caution lamp
lights up in red.
The fuel level is 120 ℓ or below. Check the fuel level, and add
fuel.
ECO GAUGE
ECO gauge indicates the instantaneous fuel consumption (fuel
consumption rate at each moment).
The instantaneous fuel consumption varies depending on the
operation ways (accelerator operation, travel speed, gear
speed, etc.) and the given load during travel (load weight,
slope, ground condition, etc.).
As the indication of ECO gauge is higher, the fuel consumption
is higher.
Reduce the indication of ECO gauge to the level where there is
no adverse effect on the operation, it leads to energy saving
operation to reduce the fuel consumption.
REMARK
Even if the indication of ECO gauge is in orange range (A), it is not a machine trouble.
Target fuel consumption (B) displayed by ECO gauge can be changed as necessary.
For the method of changing the target fuel consumption (B) displayed by ECO gauge, see."SET TARGET FUEL
CONSUMPTION VALUE DISPLAYED IN ECO GAUGE (3-64)"
