I spent seven years at two dealerships. The first (Stihl/Echo) wouldn't warranty anything themselves; they were mostly a lawn and garden shop that sold some saws, mostly smaller and mid-sized saws. The second shop (Stihl/Jonsered/Husqvarna) I worked at- we warrantied many things and took it in the shorts quite a few times to make customers happy. That shop was owned by a large logging company and we were the premier dealer for the area loggers and falling contractors. My experiences with Stihl have been a mixed bag. On a couple of occasions, they requested the customer's equipment for "research" and then never gave the equipment back or issued a refund. I have seen them go out of their way quite a few times but I've also had them tell me no on many simple, low-cost warranty fixes.
