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.

202 kW, 271 HP

The common rail type fuel injection system provides
maximum power with minimum emissions. This engine
meets EPATier 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).

● 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

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 short
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.

All the oil from the switching pump returns to the tank.
Hydraulic load is reduced and large power flows to the tires.

When raising lift arm

All the oil from the switching pump flows to the work equipment.
The raising speed of the lift arm is increased.
