MS 170 Chain brake Problem

[Rob Hornett]

Any sugestion, please Ladies and Gentlemen

i have an MS170 brought 2009, its had light to moderate use since new but now using it almost daily.

 

since monday the chainbrake has become harder to apply.

the saw is regularly maintained and inspected,

 

when removing the small cover that houses the spring and cam for the chainbrake, there is slight wearing from the spring on the cam and the un coiled end of the spring itself is slightly miss shapen where it passes over the cam.

 

is it normal for this saw to have this problem?:confused1:

any advise please

Rob

Id just replace any worn parts as parts are as cheep as chips.

I had the same problem on a ms260, replacing the linkage between the brake handle and brake band solved it, don't know how much, the parts are but fairly simple to fit yourself.

 

Hope this helps.
