If you're looking to make it looser, then take the side plate off and there are 4 square plastic tabs there on the side of the spool. They are magnets. You can take a knife or small screwdriver and click a couple of them back and that will loosen up your spool a LOT.
My advice is start with 2 in 2 out... middle of the dial on number and about 1/3 screwed in om the spool tension. Get a feel for it and loosen up from there... i crank my drag down TIGHT but thats up 2 u
