4 Lateral stability is increased by 30% (compared withthe fixed gauge of the current model). Complies with transportation regulations by retractingthe production and low fuel consumption areachieved through the following two operationmodes:Active mode, with maximum engine output to handle largeproduction, while keeping fuel consumption low; and Ecomode for light duty applications, which enables operationat a speed comparable to Active mode with even lower fuelconsumption. The two modes, Active mode for handling large production and Eco mode for low fuel consumption have been significantly MODEThis mode handles large production by providing powerfuland speedy operation, and achieves economical efficiency bysubstantial reduction of fuel MODEO peration speed equal to that of the Active mode can beachieved when handling light duty operation while alsokeeping fuel consumption Controlled High Power Engine InstalledA 246kW (330HP) Komatsu SAA6D125E engine, is thelargest in its power and low fuel consumption are achieved byoptimizing fuel injection via electronic Digging Force among the 40-ton ClassWith the addition of a one-touch power max.
