Make sure the chain brake is off (gloves will protest your fingers).
If necessary, loosen the bar nuts that are clamping the clutch cover in place (or whatever holds the clutch cover and bar on). They do not need these really loose - finger tight will do.
Ease the tension adjustment until the chain is obviously loose.
Using one hand, hold the nose of the bar up.
While holding the nose up, adjust the tensioner so that the center of the chain just touches the underside of the bar, add a touch more (1/8 or less).
Continue holding the nose of the bar up & tighten up the bar nuts / bolts / quick-release system.
The heading says this is an AV, is it actually an AVX? (tool-less)? If yes, contact Poulan there may be an unannounced repair. If not post back, I will help you you turn it into a tried and true bar adjustment system for less $ than you can repair what you have. ALL problems with the adjuster will disappear once modified.

I am confused, you say Husqvarna but it is listed as a Poulan. We need make, model and serial numbers clarified to provide ant real help, please. Lou I am confused, you say Husqvarna but it is listed as a Poulan. We need make, model and serial numbers clarified to provide ant real help, please. Lou
First, if the chain is getting hot it will get longer making it seem like it is loosening up, if this is the case turn up the chain oil adjustment, and make sure that you loosen it up before you store it as the chain will shorten as it cools and can put a lot of stress on the engine bearings.
Next, If it is a new chain they can stretch as they break in, you will have to keep adjusting it for a while as this happens.
Finally, the two nuts that hold the bar on the saw should be plenty to keep the chain tight. if the bar is moving inwards you might be putting too much stress on the chain, try getting your chain sharpened by a pro at a saw dealer or cutting a bit slower if it is sharp, you know let the saw do the work.
Be careful, the chain coming off can really ruin your day.
