Was chain sawing a Monterey Pine today and have a few basic questions:

My main question is about the chain:

I was stupid, it seems, and I had been buying chains from Home Depot, who
only sells the Y62 chain for my 18-inch Husky 445, which I only recently
found out, really takes an H72 (which Lowes sells) chain:

So *maybe* that's why my chains kept falling off while cutting?

What damage could I have done by running at least two chains (maybe 3)
that were, in effect, the wrong chains because Home Depot sold me a Y62
instead of what Lowes sold me, which is the H72 for that Husqvarna 445
chainsaw.

You had to stop and put the chain on many? times.
