Question: Weedeater

I would like to know if this part is feed my winding string around a spool or is it feed my cut strips of string insert into head. Thanks
WJA
Hello 1201507,

The part number 308042002 Spool Retainer (or bumper knob) is the part you tap on the ground to advance the string. There is usually a blade in the guard that will cut the line to the correct length after it has been advanced.

Hope this helps,

Question: Ryobi

DJD

I am looking for the string replacement spool and string. Is that what this is? I have the RYOBI RY30020B String trimmer CS30. The string won't advance for some reason so I thought I would order the spool with .080 string on it. Will this fix the issue and is this spool retainer it?
WJA
Hello DJD,

If you are having problems with the string advancing. I think the part you should order is part number, 000998230 complete string head. It includes the complete assembly, including the string to get you back trimming again.

-WJA
The string was advancing, it the bolt that holds the head on that is an issue. I know I need the bumper head, but should that bolt get stuck?
