See page 8.

Large Comfortable Cab

• Low-noise cab, similar to passenger car

• Low vibration with cab damper mounting

• Highly pressurized cab with optional air conditioner

• Operator seat and console with armrest that enables operations in
the appropriate operational posture

See page 6.

Ecology and Economy Features

● Low fuel consumption by total
control of the engine,
hydraulic and electronic system.

Reduces fuel consumption by approx. 10%.
(Compared with the PC270-7)

● Low emission engine

A powerful, turbocharged and air-to-air
aftercooled Komatsu SAA6D107E-1 provides
140 kW 187 HP. This engine meets EPA Tier 3
and EU Stage 3A emission regulations, with­out sacrificing power or machine productivity.

• Economy mode improves fuel consumption.

• Eco-gauge for energy-saving operations

• Extended idling caution for fuel conservation

● Low operation noise

The dynamic noise is lowered by 1 dB compared
with the PC270-7, realizing a low noise operation.

● Large Drawbar Pull

Provides superb steering and slope climbing
performance.

See pages 4 and 5.

Easy Maintenance

• Long replacement interval of engine oil, engine oil filter, and
hydraulic filter

• Remote mounted engine oil filter and fuel drain valve for easy
access

• Equipped with the fuel pre-filter as standard (with water separator)

• Side-by-side cooling concept enables individual cooling modules
to be serviced.

• Equipped with the EMMS monitoring system

See page 9.

Photo may include optional equipment.

Safety Design

• Cab dedicated to hydraulic excavator for protecting the
operator in the event of a roll over accident.

• Anti-slip plates for safe work on machine

• Safety enhancement with large side-view, sidewise, and
rear mirrors added.

• Rear view monitoring system for easy checking behind the
machine (optional)

• OPG top guard level 2 capable with optional bolt-on top guard

See page 7.

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 Energy­saving 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 CO

2

emissions and efficient fuel consump-

tion.

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 10% reduced

Compared with the PC270-7 at P mode and
100% working efficiency.
Fuel consumption varies depending on job
conditions.

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.
