I don't know how to access the bottom of the shaft and spool of the string trimmer to change the string. The model is Super Trim, made in USA, but an older, light /small electric model. Should the cover pop off, unscrew, twist off, What?

SOURCE: Ref: Stihl FS46 string trimmer. Broken Flex shaft.

Remove orange sheild,remove single screw holding head in shaft then grab head with pliers and twist side to side until complete head is free.You should then be able to grab part of shaft.On power head loosen screws {about one turn each} that hold two white case halves near trigger,I think there are four,then there is a single torx screw on the bottom of lower case half in the middle that must be taken out to allow tube to be removed.Romove flexshaft from top.Check 4 plastic burnt to flexshaft,if there is you must replace tube liner as well,usally around bent part of tube the liner will go bad.

Hold orange spool containing string while twisting the black plastic cap in the center, counterclockwise. This retaining cap is loosely spring loaded, so watch for the spring falling out. Once this locking cap is removed, the spool pulls right off.

SOURCE: B & D auto feed string trimmer won't advance string

Is the string spool seated on the rachet correctly? If so and all is well, it is worth noting that these trimmers auto feed fuunction is problematic at best, requiring manually unwinding some line every few minutes as the unit gets older.

SOURCE: I have a Toro 12 inch Toro Electric trimmer and I can't get the spool off to change. Any solution?

I am having the same problem - the spool should just come off by turning it counter-clockwise but is completely stuck. This model does not have any tabs that need to be pushed in to get the spool off. Very frustrating!

I have an 11" Toro trimmer and was having trouble deciphering the symbols on the base. The key is having a method to gain some opposing force to unscrew the cap that holds the spool. I have an oil filter wrench called the round wrench. It is a steel bar with an attached length of rubber belt that can tighten around cylindrical objects. I used that to oppose the unlock direction on the trimmer and "voila", no tabs to push no trick with the button, you just need opposing force.
