stihl FS 250 trimmer ? (1 Viewer)

[nspctr1]

I am finally ready to change the head on my trimmer to a chisel blade. The parts guy asked if the shaft was "ribbed" or straight? How do you tell? If I pull the line cap off I cant see the shaft so I will probably have to remove the line cup but dont know how. Does it take a special wrench?

Thx

Takes a special tool (I.E. and allen wrench).

From the top, rotate the sting head counter clockwise easy peasy.
