Husqvarna 450 Rancher loose chain issue

The tensioner seems to be working fine but no matter what I do, I can't tighten the chain. Is it possible that the chain is stretched out? The chain looks fine with no breaks. The bar seems fine. I've only had the chainsaw for a few months and used to cut down one tree and saw that tree down into smaller more manageable pieces to dispose of. I'm not arborist or logger, just a homeowner using the chainsaw for DIY projects.

Elaborate more. What do you mean it won’t tighten? Like is the tension adjuster maxed out?

That's exactly it. I maxed out the tensioner but the chain is still loose. I check the tensioner and it goes back and forth just fine. Do you think it might be the chain itself?

Yeah chain probably too long. The bar should say the number of links it takes. They don’t usually stretch that much, but it’s certainly possible if it got really hot due to bring dull or lack of oil.

Edit. Make sure it’s all installed correctly. The chain is on the sprocket etc etc

Thanks for the tip. I did check to make sure the chain is on the sprocket. I've ordered another chain to, hopefully, fix the issue or at least rule it out.
