Kick-down
switch
Tilt Steering Column
& One-Glance Monitors
The steering column can be easily tiltadjusted to the most comfortable position with one lever. The two-spoke
steering wheel allows maximum visibility of the monitor panel and the forward work environment.
Easy to Use Joystick
Steering (Optional)
A joystick steering system has been
incorporated to allow steering and forward/reverse selection to be controlled
by wrist and finger without the operator
having to move his arm from the arm
rest.
Faster Pile-Penetration
& Dozing
A kick-down switch down-shifts the
transmission from forward 2nd to 1st
gear, for increased rim pull and
improved dozing. When the direction
control lever is set to reverse, it automatically up-shifts from 1st gear to
2nd, to reduce cycle time.
Engine Speed Setting
System
Activating the system allows the
operator to increase (decrease) the
engine speed and maintain the
desired speed setting. This makes
long-distance travelling easy since
the vehicle can be operated with
operator’s foot released from the
accelerator pedal.
Ergonomically-Designed
Controls
All controls are ergonomically
designed to minimize operator fatigue.
The steering wheel and instrument
panel are similar to those of a car.
The blade controls have PPC valves
and short-stroke levers, to reduce
operator effort. The electrically controlled transmission and finger operated control levers allow direction and
gearshift operations to be performed
without the operator removing a hand
from the steering wheel.
Roomy, Quiet Cab
With Power Windows
The cab is large, with a comfortably
spacious interior and power windows.
Also, a wide viewing angle is guaranteed because the cab is pillar-less.
The high-capacity air conditioner
ensures operator comfort, no matter
the exterior conditions.
Low Vibration & Noise
The cab rests on Komatsu viscous
damping mounts (rubber and silicon
oil) to reduce vibration and noise. All
hydraulic equipment is mounted on
high-resistance rubber to further
reduce vibration and noise.

High Productivity and Reliability Operator Environment
Proven Power
The Komatsu SAA6D170E-3 delivers
power and efficiency to get the job
done quickly and cost-effectively
while meeting EPA and EU Tier 2
emission regulations. The engine is
a water-cooled, four-stroke, six-cylinder in-line, turbocharged, air-to-air
aftercooled, direct injection engine
that produces high performance and
excellent fuel economy.
Torque Converter Lockup
System
Switching the torque converter lockup system on transmits all of the
engine power directly to the transmission for greater efficiency during
long pushes. The result is efficient
use of engine power, less fuel consumption, and faster cycle times.
Reliable Power Train
The engine, torque converter and
transmission, as well as the
hydraulic equipment and electrical
parts, undergo strict quality control
checks for enhanced reliability and
durability.
Durable Blade
Komatsu blades are manufactured
using high-tensile strength steel providing excellent rigidity and
increased dozing capacity.
Flywheel horsepower

Blade capacities
8.0-22.5m
3
(10.5-29.4cu.yd)
Built-in Blade Tilt Piping
Blade piping is built into the straight
frame to protect it from damage.
High-Rigidity Frames
Front and rear frames are designed to
work in the toughest applications and
provide high rigidity for the power train
and dozer equipment. The high-rigidity
frames, together with the reinforced
dozer linkage, reduce dozing stress
and shock.
High-Quality Paint
Exterior surfaces are treated with a
cationic electro-deposition undercoat
and melamine baked final paint for
rust resistance and longer service life.
Non-Spin Differential
(Optional)
The field-proven non-spin differential
prevents tire slippage on slippery terrain such as soft or sandy ground, so
stable travel is ensured and tire wear
is reduced to a minimum for maximum
tire life.
Maintenance-Free
Braking System
Service brakes utilize two hydraulically-actuated independent circuits for
increased safety and are adjustmentfree, fully-sealed, wet disc units, preventing intrusion of dirt and dust. Since
the brake system does not use air, it
provides many benefits such as
absence of condensation, dependable
braking even in cold conditions, no
need for drainage, and rust free piping.
Charging time after engine starting is
drastically shortened and pedal effort is
reduced.
Simple Checks,
Easy Maintenance
The main monitor and the maintenance monitor (EDIMOS II) are neatly
arranged on the instrument panel for a
quick, clear reading of machine functions at all times. The main monitor
also has a diagnostic function.
