Husquarvana 560xp problems cutting out

[Cass8861]

I bought a 560xp about 4 months ago and just recently it has become a bit of a nightmare for cutting out then an absolute pain to start after it. Also I have went through 2 air filters as they keep melting to the top cover has anyone else had the same problems or have some sort of incline as to what the problem could be? 

 

Kind regards

the fact you say it’s melting air filters says it’s running to hot. Are the cooling fins clear and not coated in sap? First thing I would be doing is removing the exhaust and having a look at the cylinder and piston.

The only time I saw anything like melting air filters was on 372 this was traced to an ignition unit fault, it would back fire through the inlet and in doing so melt the filter screen, could be a similar fault, as for over heating cylinder, no way.

Hi Sveriges

All seems to be ok with the fins they are all clean. I will take the exhaust off after work today and have a wee look. What should I be looking for. I’m pretty new to the chainsaw world so everyday is a school day ?

That looks more like friction melting, is the air filter housing correctly fixed into the rubber mounts, or sitting on top of them, this could cause the filter to contact the the cover and the vibrations of the saw cause some melting.

Still thinking about this, is it possible the spark plug is loose and hot gasses are escaping causing the filter to melt?

Dave did a test on the 550 and a bit with the 572 in another video. The new 572 comes with more vents cut in to the top cover than the 560 used to. The newer top covers on all their saws appear to all have more vents to help reduce the issues from over heating.

 

Also of note, after looking at the most recent photos there, it appears there really should be a partition between the two areas there, the intake and the cylinder. The new 572 has one, I dunno how the 560 and 550 go about this, or whether he is simply missing it or if it was never there to begin?
