Let me preface this by saying, this is my first big boy chainsaw. I made do for my previously (more limited) needs with an el-cheapo electric one of the sort where you just buy a new one if it breaks.
I picked up a used 440 Magnum. Seems to run fine, except that the tensioner isn't working correctly. I can turn the screw forever and it never moves forward. If I apply sideways pressure on the nub while turning the screw, it will slide forward, but not smoothly, it sort of jumps and skips. And then once the tensioner is at maximum extension, if I push it backwards with a finger, it takes very little pressure and it will slide all the way loose.
I'm going to assume something is either broken or disconnected. I'm also going to assume this part is commonly subject to breakage.
Question 1: Would anyone like to speculate from my lay-person description of the problem as to what part may be broken?
Question 2: Assuming you think you know what part needs replacing, is this a DIY job or am I likely to break other stuff and I should bring it to a shop?
Thanks in advance.
