Make a sharp bend in the line and insert it into the hole in the spool hub. Start wrapping the replacement line in the direction shown on the spool.

The motor is failing. Most likely the brushes have failed, but this is all sealed and they cannot be replaced alone.

I have a Ryobi Model RY28040 straight shaft line trimmer. In my case I replaced the complete String Head Assembly that includes the String Head Housing, Spring, and Spool and the string still did not advance. I then discovered that the bolt in the Spool Retainer cap (the red cap that attaches the spool to the shaft) was fused and not moving. The bolt needs to be loose inside the cap in order to allow the spool to move in and out by the spring. I loosened the bolt and fastened the spool back onto the shaft. Fired it up and bumped it a few times and the line began to advance. Turns out I probably only needed to replace the Spool Retainer rather than the String Head Assembly.

check this manual (page 14-15)

i also have a ryobi weed wacker. if it is the same. you don"t have to remove the button. line up the 2 arrows one on wheel with bumpy edges and one by the button. you should see 2 holes feed a 2-3 foot piece of line into the hole the line comes out of for cutting and it should come out of a curved holw on the bottom by the button .tuck the end into a small round hole . pull line tight (tug on the section that you cut with). wind the string by turn the ring around the button. til desired length. if this doesn't work. google you model # and look for a manual (manual for ryobi weed wacker model # ------------.)

it sounds like the centrifugal clutch is slipping. take it to several shops and get some quotes. Most times you'll find that fixing a Ryobi is more expensive than buying a bnew one.

You need to give close attenttion to the string wrap" arrows" or guides and see if there are holes the size of the string your using is correct size to fit into these "grip holes inside the casing.
