EPF Scheme - resignation from service

It is written in Form-19 that in case of leaving service, the claim should be submitted after two month from the date of leaving service provided the member continues to remain unemployed in an establishment to which the Act applies.
What exactly is the meaning of the PROVISO?
Does the period of two months applies to all the members of the scheme i.e. does it apply to resignation also?
What are the other docs./formalities which are to be submitted?
It would be more helpful if anyone could provide me paragraph 69 of EPF Scheme.
