258 Power hydraulics circuit III/IV input window. If necessary, press and hold the u button until a flow rate is shown. or Power hydraulics circuit III/IV X Equipment with load sensing: press and hold the t button until LS is shown in the input window. The power hydraulics (VarioPower ® ) are loca- ted in a separate frame in the platform sub- frame. This has enormous pay load advan- tages, e.g. for snow-clearing and protecting the hydraulic components from corrosion. If the power hydraulics are not needed, they can be removed, including the frame, from the platform subframe. Further information can be obtained from a Mercedes-Benz Ser- vice Centre.
The following components of the power hydraulics are located in the platform sub- frame: General notes Attached equipment with constant flow rate, change the flow rate X Using the u and t buttons, increase or decrease the flow rate. Hydraulic system Activating side and rear working hydraul- ics system circuit II X Press the 9 button on the steering wheel or the black button on the control lever until the indicator lamp in button J lights up. Side and rear working hydraulics circuit II is activated. The symbol for side and rear working hydraulics circuit II \ is coloured.
R Hydraulic oil reservoir R Hydraulic pumps R Oil cooler Switching side and rear working hydraul- ics circuit II back to standby mode R Oil filter The hydraulic pumps are selectively driven via a propeller shaft from an engine-driven power take-off. The power hydraulics consists of two open oil circuits. It operates continuous consumers or attached equipment that consume low quan- tities of oil. X Call up the Hydraulics menu window ( Y page 237). X Using the r or s button, select side and rear working hydraulics circuit II. X Press the 9 button on the steering wheel or the black button on the control lever until the indicator lamp in button W flashes.
The symbol for side and rear working hydraulics circuit II \ has a coloured bor- der. Side and rear working hydraulics cir- cuit II is in standby mode. Activating/deactivating the power hydraulics General notes Deactivating side and rear working hydraulics system circuit II ! Only switch on the power hydraulics when connected to an item of attached equip- ment. There is otherwise a risk of damage to the power hydraulics. You must switch off the power hydraulics when you have finished using the equip- ment and when you are transporting it. X Press button W . The indicator lamp in button W goes out. or X Switch off the hydraulic system ( Y page 230).
