Genuine Answers for Land and Environment Optimization
● Largest digging force
Bucket digging force and arm crowd force are largest in its class.
● Largest bucket capacity in its class. The wide opening shape and
shallow bottom facilitates loading.
● Faster hydraulics
The high-output engine on the PC1250-7 provides plenty of hydraulic
horsepower for faster cycle times and increased productivity.
● Fuel consumption is reduced 13% with Economy Mode.
See page 4.
Productivity Features
● Strengthened boom
and arm have larger
cross-sections and improved welding for maximum strength and reliability.
Excellent Reliability and Durability
● Two-mode setting for boom
Switch selection allows either powerful digging
or smooth boom operation.
● Shockless boom
Switch selection reduces chassis vibration after
sudden stops.
See page 5.
● Boom foot hoses are arranged on the inside,
improving hose life and safety. See page 6.
Harmony with Environment
● Low emission engine
Powerful turbocharged and air-to-air aftercooled Komatsu SAA6D170E-3
engine provides 485 kW 651 flywheel HP.
See page 4.

Hydraulics
Unique three-pump system assures smooth compound movement of the
work equipment. OLSS (Open Center Load Sensing System) controls all
three pumps for efficient engine power use. This system also reduces
hydraulic loss during operation.
Active and Economy mode
The PC1250-7 excavator is equipped with two working modes. Each mode
is designed to match engine speed, pump speed, and system pressure
with the current application, giving the operator flexibility to match equipment performance to the job at hand.

Working Mode Selection
Heavy Lift Mode
Gives the operator approximately 10% more lifting force on the boom
when needed for handling rock or heavy lifting applications.
Two Settings for the 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.
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.
Shockless Boom Control
The PC1250-7 features a shockless
valve (double-check slow return valve)
that 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 prevented.
Two Working Modes
Heavy Lift Mode
Engine
The PC1250-7 gets its exceptional power and work capacity
from its Komatsu SAA6D170E-3 engine. Output is
485 kW 651 flywheel HP providing more hydraulic power.
In addition, the fuel consumption is reduced by 13%
when using Economy Mode.
Noise levels are reduced for greater operator comfort.
Largest Bucket Capacity
Bucket capacity is the largest in its class and its large
opening and shallow bottom offers easy loading.
Improved Machine Stability
The center of gravity is moved rearward and the 18.0 tonne
19.8 U.S. ton counterweight provides the stability and lifting
capacity needed for maximum productivity.
Additional Features
• Large digging force
• Large drawbar pull
• Fast cycle times

etc.
The controller finds any abnormality, and displays it on the
LCD.
2. Maintenance Monitor Function
informs replacement time of oil
and filters on LCD when the
replacement interval is reached.
3. Trouble Data Memory Function
stores machine abnormalities
(error codes) in the monitor for
effective trouble shooting.
