This is the best I can do. Hopefully someone with better translating skills will post.
Basically someone has done all of the work or is almost finished with the work. The person being talked to doesn't have anything they can do to help so yes he or she is free to do something else.
So he doesn't have something to do.
He is free.
He did all works he have to do.
Is it right?
