starts to enter red range (A) during operations, it shows that the
engine oil pressure is abnormality,
Check the lubrication system and the oil level in the oil pan as

and check the lubrication and the oil level in the oil pan.

tion target is being achieved. If the gauge is in green range A,

has gone over the target. When setting the fuel consumption
target, see “ECO Display (3-52)“.

played on the monitor. If the machine is waiting for work or tak-
ing a short break, stop the engine to reduce unnecessary
