Here's a PDF of your trimmers assembly.

If that isn't your trimmer goto:

And use the "PARTS LIST" files, they're the diagrams. Owners manuals on
your trimmer have nothing about the construction of the engine.

And yes the attachments should work with almost any trimmer, just check
the "flexable drive shaft's" connector to make sure they are the same
size and shape.

Good luck,
