OPERATION
ECO GAUGE / DRAWBAR PULL GAUGE
The ECO gauge/ drawbar pull gauge displays ECO gauge (in-
stantaneous fuel consumption) (C) or drawbar pull gauge (work
load) (D).
The instantaneous fuel consumption means the fuel consump-
tion rate at each moment, which varies with the work load and
engine speed.
When the gauge is in green range (A), the instantaneous fuel
consumption is at a good to medium level.
When the gauge is in yellow range (B), the instantaneous fuel
consumption is at a bad level.
REMARK
Although there is no abnormality on the machine when the gauge enters the yellow range, for the conservation
of global environment reduce the engine output to a point where there is no adverse effect on the operation.
Perform energy saving operations within the green range. Travel less frequently. It also helps energy saving op-
erations. Consider the best way of operation for energy saving.
For switching the display, see "ECO GUIDANCE (3-55)".
FUEL CONSUMPTION GAUGE
Fuel consumption gauge shows the average fuel consumption
of the machine.
(A): Shows the average fuel consumption of a day (from 0:00
a.m. of the day to 0:00 a.m. of the next day).
(B): Shows the split fuel consumption under measurement.
(C): Shows the split fuel consumption while measurement is
stopped.
REMARK
Display on the fuel consumption gauge can be switched be-
tween the average fuel consumption per day and the average
fuel consumption during a selected period (split fuel consump-
tion).
For the procedure for switching the display, see "ECO GUID-
ANCE (3-55)".
DEF LEVEL GAUGE
DEF level gauge indicates the remaining level of DEF.
If the indicator is in green range during operations, it is normal.
If the indicator comes close to (A) of red range during opera-
tion, check and add DEF.
(A) to (B): Red range
(A) to (C): Green range
When the indicator is in red range from (A) to (B), DEF level
caution lamp (1) lights up in red.
If DEF level further decreases after the lamp lights up in red,
the engine output power and engine speed are limited. For de-
tail, see "HANDLE UREA SCR SYSTEM (3-113)".
When remaining level of DEF cannot be detected, DEF level caution lamp (1) lights up in white.
