String trimmer out of whack? It's time to face the fix. Whether you are a legendary landscaper or a weekend weed whacker, eReplacementParts.com provides the parts, procedures and facts you need to fearlessly fix what fails you.
The slider springs are is part of the trimmer's internal bump-feed mechanism. Their job is to return the slider to its idle position, which prevents additional line from feeding out of the trimmer head. After years of use, the slider springs can become weak, damaged, or even lost; and the auto-feed mechanism will no longer work properly.
This article provides step-by-step instructions for removing and installing the slider springs on a Ryobi trimmer.
Let's get started.

REASSEMBLING THE UNIT [top] 4. Reinstall the plunger.
Install the plunger spring onto the shaft.
Install the plunger onto the shaft. Note that the angled edges of the plunger should align with the angled edges of the slider.
Depress the plunger against the slider until the groove for the C-clip becomes visible on the metal shaft.
Use long-nosed pliers to install the C-clip into the groove on the metal shaft (and secure the plunger).
5. Reinstall the reel and line assembly.
Note that the reel assembly contains an assortment of clips (cut-outs) for holding the line in place. The V-shaped clips are designed to hold line in place for longer periods of time (such as storing pre-wound reels). The L-shaped clips are designed to temporarily hold the line in place for installation of the reel assembly.
Rewind the spool until approximately 6 inches of line remains exposed for each of the two lanes. Clip the exposed line into the L-shaped channels on each side of the reel.
Thread the lines through the metal eyelets on the spool (one line per eyelet). The lines should pass from the inside of the spool to the outside.
Install the reel assembly onto the shaft.
Once the reel is seated within the outer spool, gently tug on the two lines to free them from the temporary clips.
6. Reinstall the bump head knob assembly.
Install the bump head knob assembly onto the shaft.
Compress the spring while rotating the bump head knob until the internal threads engage.
Continue rotating the bump head knob until the assembly is hand-tight.
