I am looking for Opel Corsa D 1.2 63KW workshop (A12xer)

Good to all. I recently acquired this second -hand car and I would like to know all the engine maintenance details. I have found some manual but none is from the car engine. It is the A12xer, a 1.2 of 63 kW. In some pages, information appears about the review intervals and others, but nowhere as in the workshop manual.

Thank you very much in advance!
Greetings
