I need help to open a manual !!

Hello, I need help to open a workshop manual that I just got down, I decomprint with Winrar by extracting the file in a folder with the same name, which contains several folders and I don't know what I have to do now to access the manual or reproduce it.
Thank you so much.

Cordial greeting from Manizales, Colombia. Search in each of the folders that I think Winrar when decompressing the file and places those of the PDF type. By double clicking, it would open, of course having installed a reader program of such files. Or you can send me the file to my email and I solve the problem ().
