Ms260 chain brake won't stay fixed!

[RobRainford]

My little 260 destroyed a brake band the other week. Fixed it and it was ok. But now the spring that is in the mechanism won't stay connected to its little post at the back of the unit. It's 3 times now its come off and it's getting annoying. It seems it might be bent but I straightened it and it came off again.

 

Any ideas for this? It's a great little saw but I'm reluctant to use it without a chain brake!

The spring is suppose to be bent inwards slighty, on the longer end.

 

Also has the lever th spring connects to ok and does it have the E clip on it. And is it on the post all the way in so the clip sits in the groove on the post?

Mine used to eat chainbrake bands and springs, self or dealer fitted, didn't matter, a problem I've never had with any other saw.

 

I virtually gave it away in the end, and wouldn't have another if they were free.

D a tree surgeons has two and I have replaced one brake band in 7 to 8 years of fixing his machines. Don't think he has had them that long but I have only replaced one on them.

I have owned dozens of 026's and only ever broken one band. If you need bits speak to yewhunter on here, he just bought my entire pile of breakers and fixers, there were at least half a dozen 26's in there

The bend is there as expected. It's where it sits on the post it keeps coming off. I don't know if its sitting out of line on the post or has bent slightly when I put it on,but it appears to sit on the groove in the post ok.

 

Ill have a bit more of a fettle and try a new spring. The rest of the mechanism is fine. I'm on the 3rd brake band with this saw in 5 years.

 

Might be time for a new one soon if it carries on. Stihl or husky?

How often does the user apply the chainbrake ?

 

I've worked with newly qualified that apply brake far too often in my opinion !

[Gareth Dalzell]

Is it a brand new spring you are putting on. I find the springs loose tension after a while and once they pop of a couple of times we just put a new one on and it solves the problem.

I wouldnt have thought there was room for them to come off with the cover in place.

I maintain alot of these saws Have a look at the spring there should be a little rubber bit around the coils of the spring if this is slit or missing the spring will keep popping off
