Well I jinxed myself.....I went to engage the blade and something happened to the button you press to engage the blade. There are two things you have to do when you engage the blade. #1 depress button #2 pull bar back. When I depressed the button it became loose almost like an internal spring became loose or broken.

So what happens now? Do I take it apart n try to fix or replace the assembly?

Must be one of those be careful what you create kind of things. What would it hurt to open up?

Well Mr Plum I took your advice and disassembled it. Even though I'm not very mechanically inclined. It was the cable, it came off inside the assembly. Put it back together n it works.

as usual when I try and fix things......I end up with extra parts. For the life of me I can't find a place to put the spring that popped out as soon as I opened it up. It works w/o it.....Lol. Any thoughts?

Most of those controls can be a bit of an art form to service. Me, I might only have a couple a year. You could try checking your full model number on the googler and looking up your part on images and see if you can actually find one apart. Save all your extra left over parts, put your wife on the flea market circuit making costume jewelry out of them and retire early? ;)

Hopefully your still out there Tom! Well the cable coming off inside the control was a fix, it did come off and affect the blade stop from engaging but now it sounds like I do have the original problem with the blade control dis engaging for some other reason. Not sure if it's mechanical or some other type of problem.

Do you think replacing the control assembly will be a fix? I been searching the Internet for the whole assembly with no luck.

Typically that what happens. I've not had one that the control didn't fix for the erratic operation.

Thanks I came across someone online with the same issue. Turned out the bar connects to the linkage which controls the blades was popping out from vibration. He removed the bar and bent it open so it wouldn't pop out. It work for him.

Gonna give it a try before I purchase a new assembly.
