5 The mode is easilyselected with a switch in the operator s cab. When the keyswitch is turned on, Economy mode is selected automati-cally. Select Power mode by using the switch when (Anti-pitching 4-wheel oil-cooled multi-ple disc retarder)The machine is equipped with 4-wheel retarder AP-FOUR(Anti-pitching 4-wheel oil-cooled multiple disc retarder) thatapplies retarding force on all four wheels. With this retarder,the retarding force is shared between four reduces the possibility of tire-lock and enables effec-tive use of retarder capacity, allowing stable downhill machine descends slopes smoothly and comfortablywithout machine body pitching since retarding force onfront and rear wheels is controlled Retard Speed Control (ARSC)ARSC allows the operator to simply set the downhill travelspeed and go down slopes at a constant speed.

6 As aresult, the operator can concentrate on steering. The speedcan be set at increments of 1 MPH per click ( 5 MPH of setting speed adjustment) to match theoptimum speed for the slope. Also, since the retarder cooling oil temperature is always monitored, the speed isautomatically performance Komatsu SAA12V140E-3engineThis engine delivers faster acceleration and higher travelspeeds with high horsepower per ton. Advanced technology,such as High Pressure Common Rail injection system(HPCR), air-to-air aftercooler efficient turbo-chargerenables the engine to be North American EPA Tier 2 emis-sion certified.

The shift-ing point is automaticallyselected depending on theacceleration of the machineto reduce excessive (Variable horsepower control)Both in Power and Economy modes, the VHPC systemdetects whether machine condition is loaded or unloadedand selects optimum horsepower setting mode, providingboth high production and low fuel consumption. Power mode:Makes best use of the horsepower toattain optimal production. This mode is suitable for operationin job sites including uphill travel with load where throughputtakes top priority. Economy mode:Sets the maximum horsepower at lowlevel to reduce fuel consumption.

8 The machine maintainssufficient power for normal operation in this selective reverse gears (RH/RL)In order to meet various operating conditions, two reversegears are provided. The switch on the panel allows theoperator to select optimum reverse gear of RH or RLdepending on the job site conditions at hand. Furthermore,the reverse gear is equipped with a lockup clutch, just likeforward gear, allowing the operator to reverse the machinewithout worrying about for normal operation. Thanks to the lockup clutch,the machine can be reversed at higher speed than the cur-rent machine while having the same for operation in job sites where there are TRUCKHD785-7 OFF-HIGHWAYTRUCK67 Automatic Idling Setting System (AISS)This system facilitates quick engine warm-up and cab cool-ing/warming.
