I need some help with my zebco fishing rod and reel?

on the rod it says its a zebco 4038 5' 6" heavy action and it has a zebco 404 heavy action closed face {spooled with a 15 lbs line} so you have to press a on to cast. the reel cast fine it's just i can't get the drag set and it's a little rough when you reel in and i want it to be smooth. lastly will this rod be good for b and catfish. if you can list a set with a repair manual that would be great
