paint brush
It is the use of a dry paint brush that is the point. Mine has the "o" ring seal and I use a brush to dust it off, that way I don't have to change the fuel filters but once a year whether they need it or not. I put the ribbings (ribbons) in the post so you could explain to the novice who read this that a sharp chain cuts ribbons in green wood but expect dust in old wood. While I don't like the new design, it does work, it takes some getting used to I did put some smilies in there to see if you were as sharp as your chains. Geuss you saw those. I talked a lot of guys cutting firewood into buying the stihl saws but have not heard so many b*ing about the o-ring problem. I know it's there, I don't like it but I do something about it other than just whine like some.
