How do you replace fishing line on an Abumatic model 120 or model 170 fishing reel?

I have no paperwork for either model that instructs you how to change the fishing line. I%26#039;ve seen schematics for the model 170 but no instructions for either model. These are the %26#039;60-%26#039;70%26#039;s vintage reels. Thank you.|||Have you try to take the top off because there should be a area in there where line suppose to go but if you have any problem you should just go to a local bait and tackle shop and im pretty sure they would help you or they would even ask if you want line on them and they would gladly put fishing line on your reel for a cheaper price then if you bought a whole 300 YRD line at the store.
