Ms660 chain brake (again?!)

[RobRainford]

It's a common issue. Caused by the exhaust warming up the mechanism side of the handle. Stihl seem unable/unwilling/struggling? To sort the issue (maybe the 661 was the fix, which didn't turn out perfect!)

 

I saw a post about greasing the mechanism an thought before I make an ugly looking piece of metal to make the handle stiff, I'll have a go at that

 

This is what I was greeted with. Lots of dirt and debris that would increase the effort needed to get the mechanism to work.

 

 

So, after much cleaning and liberal amounts of grease to the moving parts. I'm left with a very easy to operate chain break. Noticeably different from before. Time will tell if its a good fix. Should have got some pictures of it clean. The amount of black crud that came out was unreal.

 

This may affect some and not others. I'll get some more pictures to show what ive done and will update in the future on how well the fix has worked, if it did.

Done this to my MS650 today had the same problem as yours got to a point today I could not engage the brake at all. Cleaned and lubed all back to working order. Seems like a common problem as you said

[rob,s]

I've had the same problems with the 201 and 441 stihl don't make chain brakes like they used to

Cheers for the post Rob. Did you just use an airline for blasting out the crud?

[spudulike]

This is pretty typical of every saw I get in, all the MS200s are like that and are very dull to use but snap on once cleaned.

 

It just shows the need for general maintenance, this is a safety device and should be cleaned regularly.

Tip.

Get a can of spray 'JIZER' and spray around the bits. Leave it to soak for 5 minutes then just blast it out with an airline.

 

Then wash your face.

 

Caution, always wear protection when using an airline.

 

Note to Mendyplog, "Jizer" not "Cizer". (Though some of that Tuckers stuff may be stronger)
