PRODUCTIVITYI I
FEATURES
High Productivity and Low Fuel Consumption
Powerful Engine
The high pressure fuel injection in the SAA6D114E-2 engine provides optimum combustion of fuel
at both low and high speed/power applications. This engine also provides fast throttle response to match the machine’s powerful rim pull and fast hydraulic response.
140 kW, 187 HP
This engine meets EPA Tier II emission regulations and EU 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.

The raising speed of the lift arm is increased.
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.
Dumping Clearance: 2885 mm 9'6"
Dumping Reach: 1210 mm 4'0"
