Common-rail fuel injection system provides high injection pressure for low emission. Ductile cast-iron pistons and heli- cal intake ports make this engine a great fuel saver. Mode-switching system Electronic engine control provides superior climbing ability and outstanding fuel economy. High power mode with superior operating power suited to job sites where much time is spent working on inclines. Economy mode with reduced fuel consumption and operating noise should be used when working on level sites or under conditions where machine load is lighter. Automatic idling setting system (AISS) This system facilitates quick engine warm-up and cab cool- ing/warming with air conditioner. When setting the system ON, engine idle speed is kept at 1000 rpm when coolant temperature is 50˚C(122˚F) or lower. Speed automatically returns to 650 rpm when coolant tem- perature reaches 50˚C(122˚F) . 7-speed, fully automatic K-ATOMiCS transmission The K-ATOMiCS (Komatsu Advanced Transmission with Optimum Modulation Control System) automatically selects the optimum gear according to vehicle speed, engine speed and the shift position you’ve chosen. The result: the best gear for any driving situation. Oil-Cooled multiple-disc retarder and optional exhaust retarder The truck can be decelerated without frequent use of the brakes, allowing you to travel safer at higher speeds, even down long, steep slopes. Long wheelbase and wide tread With an extra-long wheelbase, a wide tread and an excep- tionally low center of gravity, the HD325-6 hauls the load at higher speed for more production, and delivers supreme driv- ing comfort over rough terrain. Big body A wide target area makes for easy loading with minimal soil spillage and more efficient hauling. Small turning radius The MacPherson strut type front suspension has a special A- frame between each wheel and the main frame. The wider space created between the front wheels and the main frame increases the turning angle of the wheels. The larger this turning angle, the small- er the turning radius of the truck. PRODUCTIVITY FEATURES 2 O F F - H I G H W AY T R U C K HD325-6 7.2m(23'7") A-frame K-ATOMiCS (Komatsu Advanced Transmission with Optimum Modulation Control System) Oil-cooled multiple-disc brakes

Cast-steel components are employed in the main frame in critical areas where loads and shocks are most concentrated. Rigorous dump body design The standard dump body is made of 130 kg/mm2 184,900 ps high-tensile-strength steel for excellent rigidity and reduced maintenance cost. The V- shape design also increases structural strength. The side and bottom plates of the dump section are reinforced with ribs for added strength. Reliable hydraulic system The oil cooler is installed below the retarder, improving the reliability of the hydraulic system during sudden temperature rises. Further, in addition to the main filter, a 52-micron line filter is set at the entrance to the transmission control valve. This system helps prevent secondary faults. Excellent footwork and durable power train By adopting electronic modulation on all levels, peak torque when shifting is reduced, raising the endurance of the power train. Electronic devices for excellent operation In the harness connection, a dual-lock connector is used to prevent loosening from vibrations and contact failure. Also, the base boards for controllers and other devices are fixed by molding (with resin) , realizing high water, dust and vibra- tion resistance. EXCELLENT RELIABILITY AND DURABILITY Protection functions supported by electronic control Item Function Downshift inhibitor Over-run inhibitor Reverse inhibitor Forward/Reverse shift inhibitor Anti-hunting system Neutral safety Even if the driver downshifts accidentally,a speed appropriate to the current gear is automatically set,preventing over-runs. The vehicle is prevented from moving backward when operating the body. This device makes it impossible to shift from forward to reverse when the vehicle,s speed surpasses 4 km/hour. When running near a shift point,smooth automatic shifting takes place. The engine is prevented from starting when the shift lever is not in neutral. When descending grades,if the vehicle,s speed surpasses the maximum for the current gear, the rear brakes automatically operate,preventing over-runs. K-ATOMiCS with “Skip-shift” Function An electronically controlled valve is provided for each clutch pack in the transmission for independent clutch engagement/ disengagement. It enables an ideal change in clutch modula- tion pressure and torque cut-off timing in response to travel conditions. This system and newly added “skip-shift” function ensure smooth shifting and responsive acceleration. “Skip-shift” function Optimum travel speed automatically selected in response to angle of ascent. Reduced frequency of shift downs and smoother operation are provided. Hydropneumatic suspension All four wheels have hydropneumat- ic suspension with a fixed throttle damper control valve that greatly reduces pitching, rolling and bouncing over rough terrain. Ideal driving position settings The 5-way adjustable operator seat and the tilt-telescopic steering column create an optimum driving posture, for increased driving comfort and more control over the machine’s operations. See everything in quiet comfort Wide windows in the front, side and back, plus plenty of space in the richly upholstered interior, give you a quiet, comfortable environment from which to see and control every aspect of your work.

ment-free caliper disc type. Centralized greasing points and oil filters Greasing points have been centralized at three locations. Fuel and engine oil filters are also located together on the left-hand remote mount, for easy, remote inspection from the ground. EASY MAINTENANCE 4 O F F - H I G H W AY T R U C K HD325-6 Availability rate with vehicle monitoring system The electronic display panel shows current vehicle condition and how to fix them with action codes and check results with service codes. Thus, vehicle management is easier and the working rate is higher. At the same time the monitoring data is saved to be used for later troubleshooting. Service code display and memory function The contents of each controller are displayed on the elec- tronic display panel in service codes. The stored vehicle infor- mation can be downloaded to a personal computer. This enables a quick response to problems and shortens mainte- nance time. This also shows the truck’s current condition and facilitates management. Action code display function If an abnormality on the truck occurs, an “E”appears on the electronic display panel with the appropriate action code, which notifies the operator how to deal with the abnormality. The operator never misses an abnormality and can take the proper corrective action.

ARSC is available as an option. This allows you to simply set the downhill travel speed and go down slopes at a constant speed (travel speed permitted from brake perform- ance). As a result, you can concentrate on steering. The speed can be set at increments of 1km/h 0.6mph per one click (±5km/h 3.1mph of setting speed) to match the optimum speed for the slope. Also, when it is predicted that the retarder oil temperature becomes overheat, since the retarder oil temperature is always monitored, operator is informed this by warning lamp. OFF-HIGHWAY TRUCK HD325-6 PLMII (lC card type payload meter) This system allows the production volume and the working conditions on the dump truck to be analyzed and managed directly via a personal computer. It can store up to 2900 working cycles. Engine exhaust retarder The retarder capacity is increased by 30%, so faster speed is permitted on the downward slope. This improves safety and hauling performance. Three-mode hydropneumatic suspension (optional) To further enhance driving comfort, automatic three-mode suspension is optionally available. This enables the operator to select one of three cushioning effects (SOFT, NORMAL or HARD), depending on road conditions, for improved damping control. ABS (Anti-lock brake System) ABS is introduced to construction machinery first in the industry by Komatsu’s outstanding electronics technology. This system prevents the tire lock under slippery condition while applying service brake and gives safety drive of the truck. ROPS This protects the operator and cab should the truck turn over.

Usable rimpull depends upon traction available and weight on drive wheels. To determine brake performance: These curves are provided to establish the maxi- mum speed and gearshift position for safer descents on roads with a given dis- tance. Read from gross weight down to the percent of total resistance. From this weight resistance point, read horizontally to the curve with the highest obtainable speed range, then down to maximum descent speed the brakes can safely han- dle without exceeding cooling capacity.
