I am constantly at odds with the store owner about his "shop warranty" practices. We do not charge for estimates, chains are $7 regardless of length or damage, and he gives ALOT of stuff away. Just replaced a head on an FS-90 yesterday where the owner had obviously hit something and damaged the head. No charge said the shop owner. I do file warranty claims on new stuff if it fails, but we eat plenty of it too. We would not be charging to test run a new saw, and he probably would have just gotten a (free) new chain and some more instruction at our place. Maybe that is why we are exploding in size, even during a terrible economy.
Let it be known that the oilers on newer saws are stingy, so when things go awry it can get ugly. More on that later. Off to have a baby.
