It is not uncommon for a chainsaw blade to stretch while you use it. Friction heats the blade and causes it to expand. Two bolts on the side are used to losen the blade so you can tighten it. My chain gets loose when the blade gets hot. I had to tighten the blade twice during about an hour of use. But I stopped when the blade got hot and let it cool. I also ran it while not cutting anything now and then to let the airflow cool it faster. I found that when I held the tip of the blade straight down and ran the motor, the oil would run down the blade. This seemed to be helping. It was a bother, but you have to realize it is one of the lowest priced saws you are going to find.

I had the same problem. Just loosen the two nuts on the bar and you should adjust it. Unfortunately chain saws do this because of heat expansion and will continue to loosen.

Loosen the two nuts with a socket wrench. Turn the tension screw clockwise with a small flat-head screwdriver. Check to see that the chain turns manually, then re-tighten the two nuts. Be careful not to hit branches and limbs with the nose of the blade.
