Chainbrake gets harder to use when saw is hot

[Swooop]

Quite common on 660's

 

Is there a cure?

[Big 'Ammer]

We have several Stihl saws which are no bother, then we have a 660 which has this problem.

 

All are maintained well, the 660 is the only one which needs the clutch drum regularly removing and cleaning out more thoroughly.

 

I'd like to know, as well?

I dont believe there is a cure, no.

 

The main problem being, Stihl dont see it as a problem although it is a common issue.

 

Think the only way to deal with it is, as Nige says clean out more thoroughly and more regularly.

 

Or, dont bother with the brake when the saw gets hot:blushing:
