3 Easy entry/exit, rear-hinged doors Telescopic/tilt steering columnSee page with Environment Meets EPA Tier II or EC secondemission Low spectator noise Low fuel consumptionBased upon the expertise, technology and success which Komatsu has accumulated over 80 years, the new brand was born to provide customers all over the world a fresh image of the innovative technology and great value of Komatsu equipment. The new brand name is GALEO. High productivity, environment-friendly, safety and benefiting from cutting-edge technology, GALEO will contribute to our environment in the 21st Answer for Land and Environment OptimizationPhoto may include optional 1:16 PM Page 25WA470-5 WHEEL LOADER4 PRODUCTIVITYFEATURESPRODUCTIVITYFEATURES P owerful EngineThe electronically controlled fuel injection timing in theSAA6D125E-3 engine provides optimum combustion of fuel at both low and high speed/power applications.

4 This systemalso provides fast throttle response to match the machine spowerful rim pull and fast hydraulic kW, 261 HPThe common rail type fuel injection system providesmaximum power with minimum emissions. This engine meets EPA Tier II emission regulations and EC secondemission Fuel ConsumptionThe fuel consumption is reduced greatly because of thelow-noise, high-torque engine and the large-capacity torqueconverter with maximum efficiency in the low-speed of Fuel Consumption:15% (compared withDash 3 technology).

5 Dual-Mode Select SystemThis WHEEL LOADER offers two selectable operating modes Normal and Power. The operator can adjust the machine sperformance 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 Mode Select SystemThis operator controlled system allows the operator to select manual shifting or three levels of automatic shifting(low, medium, and high). Manual:Transmission isfixed to gear speed selectedwith gear shift lever.

6 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 speedsbetween 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 operationon Dual-Speed Hydraulic SystemKomatsu s dual-speed hydraulic system increasesoperational efficiency by matching the hydraulic demands to work from the switch pump is completely returned to the tankwhen digging and breaking out, therefore, hydraulic flow to the LOADER is reduced and pressure is increased.

7 Thisreduces horsepower demand from the engine and makesthe operation more efficient. Kick-down switch signal alsocontrols the oil flow. This new technology is greaterproductivity at the lowest operating pumpSwitching pumpCut-off valveTankCut-off valveTankLoader pumpSwitching pumpWhen digging / scoopingAll the oil from the switching pump returns to the load is reduced and large power flows to the the oil from the switching pump flows to the work raising speed of the lift arm is raising lift armMaximum Dumping Clearance and ReachThe long lift arms providehigh dumping clearancesand maximum dumpingreach.

8 The operator caneven level loads on thebody of a dump truck easily and Clearance: 3120 mm10'3"Dumping Reach: 1305 mm4'3"( yd3bucket with )Long Wheelbase/Articulation Angle of 40 The longest wheelbase in class and the widest tread provideimproved machine stability in both longitudinal and lateraldirections. Since the articulation angle is 40 , the operatorcan work efficiently even in the tightest job Tread2300 mm 7'7"Wheelbase3450 mm 11'4"Minimum turning radius (center of outside tire)5900 mm 19'4"High Productivity and Low Fuel 1:16 PM Page 4 EMMS (Equipment Management Monitoring System) Monitor is mounted in front of the operator allowing the operator to easily check gaugesand warning lights.

9 A speciallydesigned two-spoke steeringwheel allows the operator to easily see the instrument Control and Troubleshooting Functions Action code display the LOADER has anytroubles, the monitor displays action details on thecharacter display at the center bottom of the monitor. Monitor monitors engine oil level,pressure, coolant temperature, air cleaner clogging controller finds abnormalities, all of these are displayedon LCD. Replacement time notice informsreplacement time of oil and filters on LCD when it reachesreplacement intervals.

10 Trouble data memory storesabnormalities for effective Cooling Fan and Swing-out Cooler ElementsIf the machine isoperating in adverseconditions, theoperator can reverse the hydraulic coolingfan from inside thecab by turning on aswitch on the controlpanel. The coolers canalso swing out for easy ComponentsKomatsu manufactures the engine, torque converter,transmission, hydraulic units, electric parts, and even each bolt on this WHEEL loaders are manufactured with an integrated production system under a strict quality control multi-disc brakes and fully hydraulic brakingsystem mean lower maintenance costs and higherreliability.
