Hexagon insert for starter adaptor

You use the already existing starter adaptor insert Ord.No. 67/46 to adopt it on this fan in order to use a starter optional either with a hexagonal starter extension or with its conventional fitting with rubber cone.

Avoid the chance of any rubber particles being drawn into the motor by using exclusivly for top start the rubber cones from abraison-resistant material like our Ord.No. 64/37.
