The present invention relates to a respective method of operating a continuous casting machine (1) at the start of casting, at the end of casting and for the production of a transition piece (21) .The object of the invention is to: - the quality of the strand ends (16, 18) to improve and - preventively to protect the continuous casting machine (1) during the application of the method from damage. This object is achieved by a method for operating a continuous casting machine (1) at the start of casting by the following additional method steps: - detecting a position of the strand beginning (16) in the strand guide (4), - after the strand beginning (16), preferably an upper end ( 17a) has passed the strand initial portion (17), the pair of adjustable strip guide rollers (5): Starting the pair to the strand (2), so that the pair touches the string (2); - cooling the strand initial portion (17) with Q Qnominal wherein the cooling nozzle (10), a refrigerant amount Q is less a nominal amount of coolant to the strand Qnominal initial portion (17) ausbrin and- cooling the strand main part (20) with Q Qnominal, said cooling nozzle (10), a refrigerant quantity Q is substantially equal to the strand Qnominal main part (20) ausbringt.
