Stihl 461 chain brake

Hi All 

Noticed yesterday that there is staring to be a fair bit more slack in the chain brake handle than previously. Handle itself has a fair bit of play in it but still functional although totally not like it normally is. I guess wear and tear is kicking in. Much of a job to do ?? 
??just googled it and the same question is already on here from past posts. I’ll try the advice previously given and see how it goes.

That is a loaded question, ask me and I will say relatively easy as I have been there before, ask someone with no idea and you will get a different answer. Getting the spring back on is probably the most challenging issue and can be....fun.

It is possible that one of the dowel mounts has failed but it may just need a bit of lube and a clean, It is also possible the handle guard latching parts have worn and you need a new one.

The test I do is to push the brake on from the far left, middle and far right of the handle guard. The brake should snap on with similar effort used in all three places. Often the brake will fail on the side nearest the starter cover. The brake should also sound crisp and not come on with a dull thump.

Turned out to be just full of crud, that saw gets used a lot on a granberg mini mill and it was after a couple of 4.8m cuts making 200x200 beams from a slab that it felt not quite right, not sure if the heat from the clutch played a part in how it activated but anyway once cleaned and put back together it’s back to normal. Cheers for the input.
