In order to bring the handle into the operating position it has to be turned first through 90° to a stop against a torsion spring and then it is pushed against spring pressure into its hold position. Operated in this way and with the axial force maintained, the handle can be used to crank. When „releasing“ the handle, the pressure spring return it back to the retracted position.
