How to replace a Toro weedeater pull string?

To replace the pull string on a Toro weedeater, first ensure the engine is off and cool. Remove the starter cover by unscrewing any screws, then take out the spool containing the old string. Thread a new string through the spool, wind it tightly in the direction indicated, and reassemble the spool into the housing. Finally, reattach the starter cover, and your weedeater will be ready for use.
