Caution! Careful maintenance is only possible, if the machine is clean. Especially visual inspections, e.g. for cracks, can be carried out properly only with a machine that has been cleaned recently. Therefore clean the machine thoroughly before starting any maintenance work (see also chapter "Safe maintenance of machine", subchapters "Cleaning" and "Crack inspection").

Note! The daily maintenance tasks of the machine operator include a functional test of the brakes (slewing gear brake, working brake, parking brake), steering, electrical and hydraulic systems. Also to be carried out is a daily visual inspection of the motor, hydraulic system, gearbox and axles for leakage.
