I know! I'm really kicking myself over it - but hear the story - it's almost reasonable.
The city was taking down an oak tree in the park across the street from my house. I asked them for the wood, and they agreed. So I grabbed my truck, trailer, saws and everything. I was waiting in my truck for them to drop it so I could go in and get the wood.
They have a rope around the top hooked up to a truck, and he cuts the notch, but just as he finishes, his chain breaks before he can start the back cut. Run to the shop to get another chain, while I continue to wait. I'm in a bit of a hurry since I have other things to do that day, but I sit patiently. He comes back with another chain, puts it on, and starts the back cut and it falls off right away. Well, he has the exact same saw as myself, bought from the same store even. He has ONE STINKING CUT TO MAKE, and he's about to run somewhere and get another saw or chain or something, so I figure that:
A) he's a professional
B) he has the exact same saw
C) it's ONE stinking cut and I'm standing right here
Yes, I did it - I offered my brand new MS660 with a 3' bar. He can't possibly screw it up with one cut.
Well, I was wrong, and I'll never loan out a saw to anyone again (except for my Craftsman which somebody gave to me and it actually runs).
Let this be a lesson to the rest of you as well - Never give in on your resolve to never loan out a good saw!
Yes, it's only a piece of equipment and therefore replacable, but it's also a tool of the trade, and easily messed up, unlike most every other tool I own. I'll gladly loan out a drill, circular saw, reciprocating saw, pressure washer, cement mixer, etc. But not a chainsaw.
