Well this thread is a year old and a lot more data is in regarding the 562's.
A pretty fair # of these have come back to the saw shop blown up. The air filtration and amount of debris getting past the filter is appalling. Bearings are living a very short life and a small # of the saw have a dreaded "hesitation issue".
Mine is starting the hesitation thing. Coming off idle after many bucking cuts the saw will just die. Did it 10 times the other day.
Ugh, sorry to hear.
Any ideas out there / new filters to help improve the function of the air filter?
