Working Modes Selectable
Two established work modes are fur-
ther improved.
P mode
– Power or work priority mode
has low fuel consumption, but fast
equipment speed and maximum pro-
duction and power are maintained.
E mode
– Economy or fuel priority
mode further reduces fuel consumption,
but maintains the P-mode-like working
equipment speed for light duty work.
You can select Power or Economy
modes using a one-touch operation on
the monitor panel depending on work-
loads.
Eco-gauge that Assists Energy-
saving Operations
Equipped with the Eco-gauge that can
be recognized at a glance on the right of
the multi-function color monitor for envi-
ronment-friendly energy-saving opera-
tions. Allows focus on operation in the
green range with reduced CO
2
emis-
sions and efficient fuel consumption.
Komatsu Technology
Komatsu develops and produces all major
components, such as engines, electronics
and hydraulic components, in house.
With this “Komatsu Technology,” and adding
customer feedback, Komatsu is achieving
great advancements in technology.
To achieve both high levels of productivity and
economical performance, Komatsu has devel-
oped the main components with a total control
system. The result is a new generation of high
performance and environment-friendly exca-
vators.

Fuel consumption varies depending on job
conditions.
Eco-gauge
Low Operation Noise
Enables a low noise operation using the low-noise engine and methods to cut
noise at source.
Idling Caution
To prevent unnecessary fuel consumption, an
idling caution is displayed on the monitor, if the
engine idles for 5 minutes or more.
Low Fuel Consumption
The newly-developed Komatsu
SAA6D107E-1 [ecot3] engine enables
NOx emissions to be significantly
reduced with the accurate multi-staged
fuel injection by the engine controller. It
improves total engine durability using
the high-pressure fuel injection system
developed specifically for construction
machinery. This excavator significantly
reduces hourly fuel consumption using
the highly-efficient matching techniques
of the engine and hydraulic unit and
also provides features that promote
energy-saving operations such as the E
mode and Eco-gauge.
