cylinder tapas adjustment mode

I have a question for the adjustment of the cylinder covers.
For example, in Fiat Siena Fire 16v's adjustment instruction, it says that the following should be done:
1- Adjust 3kgrs according to the order of 1 to 10
2- loosen 90 ° and press 3kgrs
and here the question: you must loosen and adjust one by one from 1 to 10 or loosen all from 10 to 1 and garlic from 1 to 10

You always press them and the challenge of the bolts is done in the order of PARTE that is established, but for that engine with 70 pounds in three batches and now.
