Disassembly instructions
The drawings and parts lists do not contain any detailed information about the type and
dimensions of retaining elements and the like.
NOTICE
Before you start dismantling them, you should therefore mark up the respective assignment
of retaining elements and the layout of the internal connections for assembly if they have to
be disconnected for maintenance work.
NOTICE
Use pullers or suitable devices to disassemble parts and components attached to the motor
shaft.
Three-phase motors of a vertical construction type can be dismantled in the horizontal
position.

length of 35 mm.
