The CX290 is an all hydraulic machine. It consists of an undercarriage fitted with tracks and a turntable bearing which supports the upperstructure frame. The upperstructure frame supports the attachment, at the front end of the machine, plus the engine, hydraulics and cab. When the operator works the controls, the engine-driven variable flow pump delivers hydraulic fluid under pressure to the control valves. The control valves distribute the hydraulic fluid to the various cylinders and hydraulic motors employed. A cooling system and oil cooler keep the fluid temperature down to normal working temperature.
