Working Mode Selection

Power and Economy Mode

The PC800-8 excavator is equipped with two working modes.

Each mode is designed to match engine speed, pump flow,

and system pressure to the current application, giving the

operator flexibility to match equipment performance to the job

at hand.

Environment-friendly Clean Engine Mounted

Komatsu SAA6D140E-5 engine is Tier 3 and EU stage 3A
emissions certified.
The SAA6D140E-5 engine adopts the world’s first cooled
EGR system with electronically controlled bypass-assist type
venturi. NOx emission is reduced 40%, while maintaining
high power and low fuel consumption.

Electronically Controlled Variable Speed Fan
Contributes to Low Fuel Consumption and Low
Noise

The electronic control system sets
the rotational speed of the cooling fan
according to the coolant, hydraulic oil,
and ambient temperature; effectively
uses the engine output to prevent
wasteful fuel consumption; and
reduces noise during low-speed fan
rotation.

Lower and Economical Fuel
Consumption Using
Economy Mode

Enables operator to set the Eco
mode to up to four levels
according to working conditions
so that production requirement is
achieved at lowest possible fuel consumption.

Reduction of Ambient Noise (optional)

Reduced noise by adoption of an electronically controlled
variable speed fan drive, large hybrid fan, low-noise muffler
and cover with glasswool, to meet EU stage 2 noise
regulations.

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

developed the main components with a total

control system.

The result is a new generation of high

performance and environment friendly

excavators.

Selection

ON

OFF

Result

Oil flow to the swing motor is increased.
180˚loading operations are most efficient.

Oil flow to the boom is increased.
90˚loading operations are most efficient.

Heavy Lift Mode

Gives the operator 10% more lifting force on the boom when
needed for handling rock or heavy lifting applications.

Swing Priority Setting

The swing priority setting allows the operator to use the same
easy motion for 180˚ loading as 90˚ loading operations. By
altering the oil flow, this setting allows you to select either
boom or swing as the priority for increased production.

Large Digging Force

Thanks to the high engine output and an excellent hydraulic
system, this machine demonstrates powerful digging force.

Maximum arm crowd force (ISO):

250 kN 25.5 ton

Maximum bucket digging force (ISO):

333 kN 34.0 ton

Work Equipment Speed Increased

An arm quick return circuit is provided for arm dumping. This
returns a portion of oil flow directly to the hydraulic tank at
arm dumping to reduce the hydraulic pressure loss.
Combined with increased bucket dumping speed, faster
loading work is realized.

Large Drawbar Pull and Steering Force

Since the machine has a large drawbar pull and a high
steering force, it demonstrates excellent mobility even when
it is being used on inclined sites.

Two-mode Setting for Boom

Smooth mode provides easy operation for gathering

blasted rock and scraping operations. When maximum
digging force is needed, switch to power mode for more
effective excavating.

Shockless Boom Control

The PC800-8 boom circuit features a shockless valve
(double-check slow return valve) to automatically reduces
the amount of vibration present when operating the boom.
Operator fatigue is reduced (which can improve safety and
productivity), and spillage caused by vibration is minimized.
