doubt it is even needed. I don't have one on any my saws that have that dog setup.I just installed pro safety felling dogs on my new 400. Would someone advise regarding the tiny circlip for the chain catcher. There's no groove in the chain catcher to receive it, all my circlip pliers are too big, and I'm sure I'll lose it in the woods if I have to remove the clutch cover to change a chain.
oops, it holds the plastic roller in place
