Working Mode Selection
Power and Economy Mode
The PC1250-8R 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.
High Power Komatsu SAA6D170E Engine
Powerful turbocharged and air-to-air aftercooled Komatsu SAA6D170E-5 engine provides 502 kW 672 HP. This Komatsu SAA6D170E engine actualizes high-power to low fuel consumption with the optimum fuel injection by electronic heavy duty HPCR (High Pressure Common Rail) fuel injection system.
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 and hydraulic oil 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
Reduced noise by adoption of an electronically controlled variable speed fan drive, large hybrid fan, low-noise muffler.

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.

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):
412 kN 42.0 ton
Maximum bucket digging force (ISO):
479 kN 48.8 ton
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 PC1250-8R 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.
