Line replacement on Troy-Bilt TB525CS trimmer

This is for the Troy Built Model TB539 4 Cycle Trimmer with the Speed Spool 2. I watched a few videos, and read a few on-line directions. The manual is absolutley useless, and the directions are far more complicated than they need to be. People who write those manulas up must be morons, because they can't tell you how to do something in simple terms. I toyed with mine for 2 hours, and after several attempts I got the line to feed through. I used the .095 refill line as specified, cut a a10ft. piece of line. First I lined up the arrows on the outside of the spool (the only arrows you will find are on the top exterior of the Speed Spool 2) with the corresponding lines (not arrows) just below the metal parts where the line comes out of. Find which hole you can feed the line completly through. I had to try both sides, as it seems to only feed completely through with one of those holes... you'll have to try both sides and see which one works. The line has to come out the other side. Once the line is fed through one side to the other, pull it through to even it off. Then you simply turn the spool head counter clockwise, and it should feed through. Mine worked, but I haven't tried to bump it yet. But at least the line did not get all tangled up inside. Oh, and by the way...I'm a female, my name is Rosemary, and if I can do it ... you can too!
