High Productivity and Low Fuel Consumption
Powerful Engine
The electronically controlled fuel injection timing in the
SAA6D125E-3 engine provides optimum combustion of fuel
at both low and high speed/power applications.This system
also provides fast throttle response to match the machine’s
powerful rim pull and fast hydraulic response.
195 kW, 261 HP
The common rail type fuel injection system provides
maximum power with minimum emissions.This engine
meets EPA Tier II emission regulations and EC second
emission regulations.
Low Fuel Consumption
The fuel consumption is reduced greatly because of the
low-noise, high-torque engine and the large-capacity torque
converter with maximum efficiency in the low-speed range.
Reduction of Fuel Consumption: 15% (compared with
Dash 3 technology).
Dual-Mode Select System
This wheel loader offers two selectable operating modes—
Normal and Power. The operator can adjust the machine’s
performance by flipping a switch.
● Normal Mode: This mode
provides maximum fuel
efficiency for most of
general loading.
● Power Mode: This mode
provides maximum power
output for hard digging
operation or hill climb.
Transmission Mode Select System
This operator controlled system allows the operator to
select manual shifting or three levels of automatic shifting
(low, medium, and high).
shifting is performed at relatively low engine speeds,
suitable for general excavating and loading.
● Auto. M: Gear is shifted at medium engine speeds
between those of L and H modes.
● Auto. H: This mode provides large rim pull and shor t
cycle time since gear shifting is performed at relatively
high engine speeds, suitable for load and carry operation
on uphill.
New Dual-Speed Hydraulic System
Komatsu’s dual-speed hydraulic system increases
operational efficiency by matching the hydraulic demands
to work conditions.
Oil from the switch pump is completely returned to the tank
when digging and breaking out, therefore, hydraulic flow
to the loader is reduced and pressure is increased.This
reduces horsepower demand from the engine and makes
the operation more efficient. Kick-down switch signal also
controls the oil flow. This new technology is greater
productivity at the lowest operating cost.
● Manual: Transmission is
fixed to gear speed selected
with gear shift lever.
● Auto. L: This mode
provides smooth gear
change and low fuel
consumption since gear
Maximum Dumping Clearance and Reach
The long lift arms provide
high dumping clearances
and maximum dumping
reach.The operator can
even level loads on the
body of a dump truck
easily and efficiently.
Long Wheelbase/Articulation Angle of 40˚
The longest wheelbase in class and the widest tread provide
improved machine stability in both longitudinal and lateral
directions. Since the articulation angle is 40
can work efficiently even in the tightest job sites.

Komatsu Components
Komatsu manufactures the engine, torque converter,
transmission, hydraulic units, electric p ar t s , and even each
bolt on this
wheel loader.
Komatsu
loaders are
manufactured
with an
integrated
production
system under
a strict quality
control system.
Wet multi-disc brakes and fully hydraulic braking
system mean lower maintenance costs and higher
reliability. Wet disc brakes are fully sealed. Contaminants
are kept out, reducing wear and resulting maintenance.
Brakes require no adjustments for wear, meaning even
lower maintenance.The new parking brake is also an
adjustment-free, wet multi-disc for high reliability
and long life.
Added reliability is designed into the braking system by the
use of two independent hydraulic circuits.Provides hydraulic
backup should one of the circuits fail.
Fully hydraulic brakes mean no air system to bleed,
or the condensation of water in the system that can
lead to contamination, corrosion, and freezing.
ELIABILITY
ELIABILITY
High-rigidity Frames
The front and rear frames have high rigidity to bear twisting
and bending loads applied repeatedly to the loader body.
Both upper and lower center pivot bearings are tapered
roller bearings having high durability.The structure is similar t o
those of large-sized loaders and the reinforced loader
linkage also ensures high rigidity.
Flat Face-to-Face O-Ring Seals
Flat face-to-face O-ring seals
are used to securely seal all
hydraulic hose connections
and to prevent oil leakage.
In addition, buffer rings are
installed to the head side of
the all-hydraulic cylinders to
lower the load on the rod
seals and maximize
the reliability.
Cathion Electrodeposition Primer Paint/
Powder Coating Final Paint
Cathion electrodeposition paint is applied as a primer
paint and powder coating is applied as topcoat to the
exterior metal sheet parts. This process results in a
beautiful rust-free machine, even in the most severe
environments.Some external parts are made of plastic
providing long life and high impact resistance.
Sealed DT Connectors
Main harnesses and controller connectors are equipped
with sealed DT connectors providing high reliability, water
resistance and dust resistance.

● Action code display function. If the loader has any
troubles, the monitor displays action details on the
character display at the center bottom of the monitor.
● Monitor function. Controller monitors engine oil level,
pressure, coolant temperature, air cleaner clogging etc.
If controller finds abnormalities, all of these are displayed
on LCD.
● Replacement time notice function. Monitor informs
replacement time of oil and filters on LCD when it reaches
replacement intervals.
● Trouble data memory function. Monitor stores

Easy Operation
Automatic Transmission with ECMV
Automatic transmission with ECMV automatically selects the
proper gear speed based on travel speed, engine speed, and
other travel conditions.The ECMV (Electronically Controlled
Modulation Valve) system engages the clutch smoothly to
prevent lags and shocks when shifting. This system provides
efficient machine operation and a comfortable ride.
● Kick-down
switch: Consider
this valuable
feature for added
productivity. With
the touch of
a finger, the
kick-down switch
automatically downshifts from second to first when
beginning the digging cycle. It automatically upshifts from
first to second when the direction control lever is placed
in reverse.This results in increased rim pull for better
bucket penetration and reduced cycle times for higher
productivity.
● Hold switch: Auto shift is selected and if the operator
turns on this switch when the lever is at the 3rd or 4th
gear speed position, the transmission is fixed to that
gear speed.

Variab le T ransmission Cut-off
The operator can adjust the transmission cut-off connected to
the left brake pedal with the switch near the operator’s seat
to set the brake/cut-off point for easier operation and higher
operating performance in variable operating conditions.
● High cut-off pressure for digging operations.
● Low cut-off pressure for truck-loading operations.
Telescopic/Tilt
Steering Column
The operator can
tilt and telescope
the steering column
to provide a
comfortable working
position.
Fingertip Work Equipment Control Lever
New PPC control levers are used for the work equipment. Th e
operator can easily operate the work equipment with
fingertip control, reducing operator fatigue and increasing
controllability. The PPC control lever column can be tilted
forward or rearward and the wrist rest can be adjusted up
or down to provide the
operator with a variety
of comfortable operating
positions.
Comfortable Operation
Low-noise Design
Operator noise: 72 dB(A)
Dynamic noise (outside): 109 dB(A)
The large cab is mounted with
Komatsu’s unique ROPS/FOPS
viscous mounts.The low-noise engine, hydraulically driven
fan, and hydraulic pumps are mounted with rubber cushions,
and the cab sealing is improved to provide a quiet,
low-vibration, dustproof with pressurizing, and comfortable
operating environment. Also, spectator noise is lowest
in this class.
Pillar-less Large Cab
(Optional)
A wide pillar-less flat
glass provides excellent
front visibility. The wiper
arm covers a large area
to provide great visibility
even on rainy days.
The cab area is the largest in its class providing maximum
space for the operator.

Rear-hinged Full Open Cab Door
The cab door hinges are
installed to the rear side
of the cab providing
a large opening angle
for the operator to enter

operator can get on
and off the cab easily.
Emergency Brake
If the brake oil pressure drops, the warning lamp flashes
and the warning buzzer sounds intermittently. If the brake
pressure drops lower, the par king brake is applied providing
a double safety system.
