If you aren't sure , take the baler out on the light and with manual in hand, compare what the manual shows vs. what you just pulled out of the barn.  I am not familiar with either baler, but this method has worked with me on other equipment. You will be able to tell if there are any similarities pretty quick.  Check any pictures that may be included and compare the picture in hand to the 710 in front of you. I would bet that while not all is identical, there will be at least some info that will be pertinent.
