[. . . ] This results in superb, fine controllability. Front radiator mask Openable and closable radiator mask facilitates radiator cleaning. Benefits of CLSS Electronic monitoring system An electronic monitoring system prevents minor problems from developing into major ones. All meters and gauges are controlled by a microcomputer, which provides a wide indication range for an easier, more precise reading. More precise and responsive operation due to the pressure compensation valve. Reduced fuel consumption by discharging only the required amount of oil from the pump. The work equipment moves smoothly for operations such as side-cutting even when priority is given to steering. CLSS for D68ESS-12 Oil pressure check ports Oil pressure check ports for the power train are centralized on the right hand side of the operator Gull-wing engine side covers Coolant reservoir Cylinder Cylinder A radiator coolant reservoir makes it easier to check the coolant level and eliminates frequent refilling. A gas-spring cylinder opens the gull-wing engine side covers widely, allowing the engine and auxiliary components to be easily checked.
