The brake band on my ryobi pcn4545 which is attached to the kick back lever isn't releasing properly and is slowing down and almost stopping the saw when using it. I fitted a new band and clutch to try to cure the fault but it is still the same. It appears that the band is too tight but I can't find any means of adjustment. Can any one help please.
Had the same problem - managed to melt the plastic housing because the band was getting hot.
Had all but given up finding a fix and there is no obvious brake adjustment.
BUT g white saved the day - shortened the spring and all is fine again - for the moment.
Thanks for the info
