Got a good sample of what a clueless homeowner can put a saw through on Sunday. Was helping a friend out at his cabin when I noticed one of his paths was blocked with a fallen tree. I knew his little Stihl ms170 should be up to the task so I volunteered myself to clean it up.
First thing I noticed was the blue scorch marks and missing paint all around the rails of the bar, it had gotten very hot. The chain had been run too tight and was still this way, no doubt contributing to the situation. The pico chain was also dull, but I thought "how bad could it be?"
Well I found out, I couldn't even get halfway through a three inch piece of wood without it starting to smoke! Well that was enough, I managed to scrounge a hobby file that was about the right size and went to sharpening the chain. And then set chain tension where it was supposed to be and tried cutting again. Now it was cutting like it should, throwing chips and going through effortlessly, at least for the first 5 inches when I found out it was cutting crooked because the rails had worn uneven!
I managed to clear the path at least, and then later that day found a cheap replacement bar and chain for him.
We take it for granted that we know what we're doing when it comes to saw use, but this makes me wonder if we are actually in the minority. What percentage of saw owners actually take the time to learn how to use the tool properly? Maybe this is why we find so many small saws in the garbage dump, they are treated like a disposable commodity, beat to death and thrown away.
