Form No. HESS5981 Printed in Japan 200306 IP. AD (15) High Productivity and Reliability Proven Power The Komatsu SAA6D170E-3 delivers power and efficiency to get the job done quickly and cost-effectively while meeting EPA and EU Tier 2 emission regulations. The engine is a water-cooled, four-stroke, six-cylinder in-line, turbocharged, air-to-air aftercooled, direct injection engine that produces high performance and excellent fuel economy. Operator Environment Tilt Steering Column & One-Glance Monitors The steering column can be easily tiltadjusted to the most comfortable position with one lever. The two-spoke steering wheel allows maximum visibility of the monitor panel and the forward work environment. Built-in Blade Tilt Piping Blade piping is built into the straight frame to protect it from damage. Maintenance-Free Braking System Service brakes utilize two hydraulically-actuated independent circuits for increased safety and are adjustmentfree, fully-sealed, wet disc units, preventing intrusion of dirt and dust. Since the brake system does not use air, it provides many benefits such as absence of condensation, dependable braking even in cold conditions, no need for drainage, and rust free piping. Charging time after engine starting is drastically shortened and pedal effort is reduced. Faster Pile-Penetration & Dozing A kick-down switch down-shifts the transmission from forward 2nd to 1st gear, for increased rim pull and improved dozing. When the direction control lever is set to reverse, it automatically up-shifts from 1st gear to 2nd, to reduce cycle time. Kick-down switch Ergonomically-Designed Controls All controls are ergonomically designed to minimize operator fatigue. The steering wheel and instrument panel are similar to those of a car. The blade controls have PPC valves and short-stroke levers, to reduce operator effort. [. . . ] The steering wheel and instrument panel are similar to those of a car. The blade controls have PPC valves and short-stroke levers, to reduce operator effort. The electrically controlled transmission and finger operated control levers allow direction and gearshift operations to be performed without the operator removing a hand from the steering wheel. Flywheel horsepower 362kW485HP @2000RPM Torque Converter Lockup System Switching the torque converter lockup system on transmits all of the engine power directly to the transmission for greater efficiency during long pushes. The result is efficient use of engine power, less fuel consumption, and faster cycle times. High-Rigidity Frames Front and rear frames are designed to work in the toughest applications and provide high rigidity for the power train and dozer equipment. [. . . ]
