Filter is on the weight in the fuel tank. Whatever you do, don't run it lean. That is too nice a saw to burn up on a lean burn.
Some of my guys have complained about the weight of our 3120, but it never bothered me. I used to occasionally pop the 24" bar on it and use it as a ground saw. It ripped up trees so fast you didn't get tired from carrying it, you got tired from moving around so much from cut to cut.
I quit using it as a ground saw, because it costs too much for common use. I save it for the big cuts. That, and it literally sucks down the fuel & oil.
