A split gear ratio can be set to high, 1:1 or low depending on the position of the shaft (1) in the relation to the indent (2), see the figure below. Markings on the split gear housing indicate ratios corresponding to shaft positions.

Secure that the shaft is in the right position with the fork-shaped tool (4141 1114 00). See the figure below.
