The chain oil tank on my HOmelite C-9 is leaking. Last nite I had the fuel tank off working on that, and tightened the oil tank screw up on top by where the bolt goes into the housing for the handle. HOw do I tighten the other oil tank screws? Does I have to split the whole saw to get to them or what do I do. THere's got to be an easier way. I think they just vibrated loose and need to be tightened. Please help!!!!! Email is [email protected] if anyone has suggestions. Thanks a million!
