FIELD: machine building.
SUBSTANCE: invention relates to operation of working machine hydraulic system. Proposed method comprises the steps that follow. Equipment configuration is retained at definite orientation to measure first pressure in hydraulic drive chamber (56, 58) connected with equipment at preset position. First signal is compared with first pressure magnitude. First functional relationship (71) is selected from multiple memorised functional relationship if said first signal is higher than first pressure magnitude. Second functional relationship is selected from multiple memorised functional relationships if said first signal is lower than first pressure magnitude. Hydraulic drive is controlled on the basis of selected functional relationship. Note here that each of multiple memorised functional relationships is associated with different category of equipment configuration.
EFFECT: possibility to modify relationship between hydraulic drive speed.
