I do not know of any other source. I think the part your looking for has also been discontinued.

Remove cup from bottom of unit by depressing 2 detent tabs and pulling away from unit.
Replace empty spool with new full one or wind on aftermarket string. Wind in direction of
arrow on spool. Make sure spool is seated on rachet firmly.

Hi Deborah,
You need to start from the beginning of the trimmer string. Remove the entire spool. Insert the start of the line through and wedge it into the little groove to keep it from coming loose. Now wind the line tightly and neatly in the direction shown on the spool. (it should provide an arrow stating to "wind this way". As you near the end of the line, keep it snug and push the end through the hole where it leads out to the cutting zone. As you re-insert the spool into the housing, make sure it stays tightly wound as you lock it into place. This should help. Usually when your string is too short, you tap the **** of the spool on the ground to advance the line. It should feed a bit at a time, and when you hear it getting cut off, you should stop advancing the line.
Hope this helps.

have a read through, it may help assist you.

Do you mean that the string keeps feeding as you try to operate the trimmer?

If so, you are winding the string on the spool the wrong way. Put the string on the spool in a clockwise direction. This should do it.

If the line keeps getting too long, it's because swivel 14 in diagram 7 was in the wrong position when you inserted the spool - just move it to the ouside position, re-insert the spool and away you go. Frankie.
