My 305 will not allow the blade to track in the middle of the upper wheel. I usually use a 1/4" blade but it does the same with a 3/8"blade. If I attempt to track the blade, the back of the teeth, in the center of the wheel the wheel will tip/flip forward and you know what the blade does. So I start over again and again. I have tried three different sets of tires including new OEM rubber tires that Makita sent me free, and the results are the same. If I want to use the saw I have to keep the blade on the back of the wheel with the front edge of the teeth barely making it to the center. And if I think the tension is a little low during use and tighten it it will frequently cause the wheel to tip forward. And yes I have tried new blades etc. The only thing that I can see is that there does not appear to be any crown on the tires when installed. But on a half inch wheel that could be hard to see.
So is this normal for this saw or am I doing something wrong or is this saw(the one I have) a POJ?
