In an elevator installation subject to maintenance by a technician, a drive system is operated to move an elevator car along an elevator shaft in response to a call entered by the technician on a first floor. The drive system is deactivated in response to a control signal generated by an elevator controller when a safety circuit of the elevator is interrupted. Interrupting the safety circuit is caused by a detector mounted on the elevator car detecting a signal transmitted by a service tool. The service tool is introduced into a receptacle of a shaft door at the first floor. After deactivation of the drive system the moving of the elevator car comes to a halt with its roof being at a level to allow the technician to step on top of the roof from the first floor.
