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
environment-friendly energy-saving
operations. Allows focus on operation
in the green range with reduced CO2
emissions and efficient fuel consump-
tion.
Komatsu Technology

Eco-gauge
Low Emission Engine
Komatsu SAA6D107E-1 meets EPA Tier 3 and EU Stage
3A emission regulations and reduced NOx emission by 29
% compared with the
PC270-7.
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.
Large Maximum Drawbar Pull
PC270-8’s maximum drawbar pull provides
superb slope climbing performance.
The optional heavy duty travel motor gives a
extra 6% increase.
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.
Reduced fan speed

Low Cab Noise
The newly-designed cab is highly rigid
and has excellent sound absorption
ability. Thorough improvement of noise
source reduction and use of low noise
engine, hydraulic equipment, and air
conditioner allows this machine to gen-
erate a low level of noise similar to
that of a passenger car.
Low Vibration with Cab Damper
Mounting
PC270-8 uses viscous damper mount-
ing for cab that incorporates longer
stroke and the addition of a spring. The
new cab damper mounting combined
with high rigidity deck aids vibration
reduction at operator seat.
Wide Newly-designed Cab
Newly-designed wide spacious cab
includes seat with reclining backrest.
The seat height and longitudinal incli-
nation are easily adjusted using a pull-
up lever. You can set the appropriate
operational posture of armrest together
with the console.
Reclining the seat further enables you
to place it into the fully flat state with
the headrest attached.
Pressurized Cab
Optional air conditioner, air filter and a
higher internal air pressure (+6.0 mm
Aq +0.2"Aq) prevent external dust
from entering the cab.
Automatic Air Conditioner
(optional)
Enables you
to easily and
precisely set
cab atmos-
phere with
the instru-
ments on the large LCD.
The bi-level control function keeps the
operator's head and feet cool and
warm respectively. This improved air
flow function keeps the inside of the
cab comfortable throughout the year.
Defroster function keeps front glass
clear.
Cab Dedicated to Hydraulic Excavator
The cab is designed specifically for hydraulic excavators and
gains reinforced strength from the pipe-structured cab frame-
work. The cab framework provides the high durability and
impact resistance with very high impact absorbency. The
seat belt keeps the operator in the seat of the cab during a
roll over.
Anti-slip Plates
Highly durable anti-
slip plates maintain
superior traction
performance for the
long term.
Pump/engine Room Partition
Pump/engine room partition prevents oil from spraying onto
the engine if a hydraulic hose should burst.
Lock Lever
Locks the hydraulic
pressure to prevent
unintentional move-
ment. Neutral start
function allows
machine to be started
only in lock position.
Large Side-view, Rear, and
Sidewise Mirrors
Enlarged left-side mirror and addition of
rear and side mirror allow the PC270-8
to meet the new ISO visibility require-
ments.
Rear View Monitoring System (optional)
The operator can view the rear of the machine with a color
monitor screen.
Thermal and Fan Guards
Thermal and fan guards
are placed around high-
temperature parts of the
engine and fan drive.
