Repair of the Martian ROBOT

[Vostok]

Hello to all ROBOT lovers

 

I have two wonderful Martian robots in my collection, but unfortunately both are out of order. I would like to fix them. Can anyone tell me (maybe someone has already disassembled and repaired such a robot) how to properly disassemble the toy and carefully remove the metal parts of the robot (so as not to damage them) It is not very clear how to open the zippers that hold them? Maybe there is a video or photo somewhere of how it is installed.

 

Thanks to everyone who will help!
