[. . . ] Power mode Great productivity can be attained by taking a full advantage of high output power. It is appropriate for job sites where larger production at uphill-hauling is required. Economy mode Engine speeds of the maximum output, downshift, and upshift are set to a lower level. It is appropriate for light Komatsu develops and produces all major components, such as engines, electronics and hydraulic components, in house. [. . . ] The total control system controls both the engine and transmission by monitoring the vehicle conditions. This high technology system assures smooth shifts without shock and maximizes power train life. Hydraulically Controlled Wet Multiple-Disc Brakes and Retarder Wet multiple-disc brakes with proven performance in larger articulated and rigid trucks are tailored for use in the HM300. The large-capacity, continuously cooled, wet-multiple disc brakes also function as a highly responsive retarder which gives the operator greater confidence at higher speeds when Articulated Steering Fully hydraulic articulated steering offers low-effort operating performance and maneuverability. A minimum turning radius of only 7. 96 m 26'1" provides ability to work in tight areas. 7. 96 m 26'1" 4. 01 m 13'2" Komatsu Designed Differential Locking Systems The full-time six-wheel drive system reduces slippage. A wet multiple-disk interaxle clutch also locks the three axles in unison for greater traction. The interaxle lock can be switched on and off while the truck is travelling, thereby boosting productivity. In addition, limited slip differentials prevent the tires on either side from slipping on soft ground. travelling downhill.

The low level of vibration and noise ensure maximum productivity from the operator. Low-noise Designed Cab Integrated cab and floor provide airtight cab. The low noise and sound insulated muffler /exhaust pipe contribute to reducing sound levels. All these together offer a quiet and comfortable operator environment. Air Suspension Seat is Standard The air suspension, fabric-covered seat which is adjustable to the operator's weight is provided as standard. The air suspension seat dampens vibrations transmitted from the machine and reduces operator fatigue as well as holding the operator securely to assure confident operation. These structures conform to ISO 3471-1994 standards. Hydro-pneumatic Suspension for all Terrains The hydro-pneumatic suspension assures a comfortable ride even over rough terrain and ensures maximum productivity and operator confidence. Viscous Cab Mounts Viscous mounts reduce the noise transmitted to the cab and achieve a quiet 76 dB(A) noise level Electric Body Dump Control Lever The low effort lever makes dumping easier than ever. Supplementary Steering and Secondary Brakes Supplementary steering and secondary brakes are standard features. Steering: ISO 5010-1992, SAE J1511 Brakes: ISO 3450-1996 Wide, Spacious Cab with Excellent Visibility The wide cab provides a comfortable space for the operator and a full size buddy seat. Large electrically operated window and the operator's seat positioned to the left side ensures superior visibility. Ergonomically Designed Cab The ergonomically designed operator's compartment makes it very easy and comfortable for the operator to use all the controls. The result is more confident operation by operators and greater productivity. The front under view mirrors are increased to three from one, and the rear view mirrors increased to four from two. Newly employed laminated glass in the windshield assures safe operation. In addition, electric heated rear window facilitates defrosting. Easy-to-See Instrument Panel The instrument panel makes it easy to monitor critical machine functions. In addition, a caution light warns the operator of any problems that may occur. This Komatsu on-board monitoring system makes the machine very friendly and easy to service. Steering Wheel and Pedals Low effort pedals reduce operator fatigue when working continuously for long periods.
