Abstract
A wind turbine () has three wind turbine blades (), each being arranged rotatably on the rotor hub () about a pitch axis in order to adjust a pitch angle of the wind turbine blade. Before performing the service work, a pitch angle adjustment is performed so that a pitch angle difference between respective pitch angles of two of the wind turbine blades is between 45 degrees and 135 degrees or between 225 degrees and 315 degrees. After performing the service work, a pitch angle adjustment is performed so that there is at least substantially no pitch angle difference between pitch angles of the respective wind turbine blades of the rotor (). During the service work, the rotor is maintained in a rotational position in which a longitudinal axis of the third wind turbine blade forms an angle of not more than 5 degrees with a horizontal axis.
