228 Overview Useful information R front working hydraulics circuit II, vehicles with positioning pump These Operating Instructions describe all the models and standard and optional equipment of your vehicle that were available at the time of going to print. Country-specific differences are possible. Bear in mind that your vehicle may not be equipped with all the functions described. This also applies to safety-relevant systems and functions. Read the information on qualified specialist workshops ( Y page 30).

If work on the hydraulic system is carried out incor- rectly, high-pressure hydraulic fluid may spray out. There is a risk of injury. Only have work on the hydraulic system car- ried out at a qualified specialist workshop. H Environmental note Environmentally compatible hydraulic fluids must be separately stored, collected and dis- posed of in accordance with waste manage- ment laws. :
