<p>The implement (4) has a working drive movable element (2), and an energy recovery cylinder (3) provided for recovering energy from the movement of the movable element provided with a gas-filled chamber (1). The working power of movable element is controlled as a function of directly or indirectly determined temperature of the gas in the gas-filled chamber. The work dynamics of the hydraulics of the gas-filled chamber are adjusted as a function of the temperature signal. An independent claim is included for method for operating implement.</p>
