I have a 6400, and although I bought it a couple years ago there has literally been about a tank of fuel through it, everything I've run into since has only required small saws...Its running carlton chain 3/8" .050 and an 8pin sprocket, and a 20" Total super bar.
Anyway to the question, on my other saws (echo cs450/homelite 33cc cheapo) when the saws are off and the chain brake is not engaged, I can rotate the chain in both directions. On my Dolmar I can rotate the chain in its cutting direction no problem, but when I go to spin it backwards it only moves an inch or two and then something feels like its binding and stops the chain from going further. What/why is that?
Its seems like who cares if it spins backwards-when the chain jams on the bar and you throttle up but the chain doesn't spin, I always just put the bar on some wood and pushed/pulled to free it up. I don't want to screw something up if its binding.
One other thing, when adjusting the chain tension, If I ever tension it a little too much, and then want to slack it up a little, its like the adjustment screw binds up and I need to force it to get to turn back to slack up the tension. Seems kind of a not so great tensioning system...
