Most exterior plates are treated with a cation electro-deposition undercoat and melamine
baked final paint for rust resistance and longer service life.
In addition, some exterior components employ resin.

- Proportional pressure control (PPC): Little effort is required to operate the bucket and boom control levers, assuring smooth, responsive bucket/boom action. [WA320 and over except WA320-3 CUSTOM]

- Tiltable steering wheel and fully adjustable suspension seat provide maximum operator
comfort. [WA320 and over]

- Hydraulic power steering system guarantees light-touch steering at all times.

- High machine stability is assured by a center-pinsupported rear axle and large oscillation angle that keep the machine level even on the roughest surfaces.

- Automatic bucket positioner assures accurate bucket positioning.

- Boom kick out device facilitates repeated dig-load operations. [WA320 and over]

- Tire saver controls tire slip and lengthens tire life. [WA1200]

GALEO Series

1- High productivity and low fuel consumption

- Dual-mode select system
This wheel loader offers two selectable operating modes-Normal and Power.

    1- Normal mode: This mode provides maximum fuel efficiency for most of general loading.

    2- 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).

- New dual-speed hydraulic system

Komatsu's dual-speed hydraulic system increases operational efficiency by matching the
hydraulic demands to work conditions.

- 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 40º

The widest tread in class and the long wheelbase provide improved machine stability in both
longitudinal and lateral directions. Since the articulation angle is 40º, the operator can work efficiently even in the tightest job sites.

- 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.

2- Increased reliability

- Wet multi-disc brakes and fully hydraulic braking 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.

- Hi-rigidity frames

The front and rear frames have high rigidity to bear twisting and bending loads applied
repeatedly to the loader body.

- 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.

- Komatsu components

Komatsu manufactures the engine, torque converter, transmission, hydraulic units, electric
parts, and even each bolt on this wheel loader.

- 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.

- Sealed DT connectors

Main harnesses and controller connectors are equipped with sealed DT connectors providing
high reliability, water resistance and dust resistance.

3- Easy maintenance

- EMMS (Equipment Management Monitoring System)

Monitor is mounted in front of the operator for easy view, allowing the operator to easily check gauges and warning lights.

- Reversible cooling fan and swing-out cooler elements

If the machine is operating in adverse conditions, the operator can reserve the hydraulic cooling fan from inside the cab by turning on a switch on the control panel.

- Gull-wing type engine side doors open wide

The operator can open and close each gull-wing type engine side door easily with the assistance of a gas spring to perform daily service checks from the ground.

4- Easy & comfortable 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

With the touch of a finger, the kick-down switch automatically down shifts from second to first when beginning the digging cycle.

- Electronically controlled transmission lever

Easy shifting and directional changes with Komatsu two-lever electronic shifting. Change
direction or shift gears with a touch of the fingers without removing the shifting hand from the steering wheel.

- Variable transmission 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.

- Fingertip work equipment control lever

New PPC control levers are used for the work equipment. The operator can easily operate the
work equipment with fingertip control, reducing operator fatigue and increasing controllability.

- Low-noise design

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.

- 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 and exit.
