Bob at the worst all you would have to do is change the sprocket and bar to use a more standard chain. I do not know what a "Special 80 dgl" is and why it would be different than a normal chainsaw chain. IF the drag thickness is the same as common chain then all you would have to do is maybe change the sprocket.
I looked on line an all I could find out that as "special" about the chain you have is that it is a low kick back type chain. You should be able to replace it with a normal chain easily.
I am not real familiar with Husky chain saws but the chains are not any different than the other brands.
You just need to know the following things to replace the chain: 1) The pitch of the chain to match it to your drive sprocket. 2) The width of the drag to match the bar.
3) The length of the chain to match your bar.
With that information you can easily find a more common type of chain.
Personally I hate the low kick back chains. They really just have the drags set to cut a smaller chip. Therefore less kick back. That usually makes them less aggressive. I don't want to have to lay on the saw to make it cut.
Also remember that things you buy at Lowes can be oddball as they just buy/sell on price. I have found much of their stuff to be of lesser quality even under major brand names.
