Hi! I have got one of these chainsaws. I am not sure if the same fault you are having, but it comes from the fact that this chainsaw burns gas very quickly. I notice that when I was in the forest, in one hour, my chainsaw's meter almost full, just to saw four trees with the length of two meters. After that, I took my chainsaw to the service, and teh mechanic told me that this chainsaw is just like that, it burns the gas very quickly, but when I took my chainsaw back, I checked it by myself, and again, in one hour, the meter was full. I don't know if you have the same problem. �I hope it helps.
