At the end of your video when you were talking about the saw and you demonstrated cutting down the small tree, your chain was waaay too loose and hanging down below the bar. With the battery off the saw for safety...when you grab the chain with your thumb and index finger and pull down on it to check it, it should only pull down about 3mm or 3/16". Any looser than that wears the chain out faster and it will eventually cause the chain to come off and it might even cause the chain to break. You probably had the chain close to tight enough when you started testing it cutting things, but all new chains get hot and stretch quite a bit and they have to be tightened up again a couple of times (and oiled every 15 - 20 mins of use with vegetable or mineral oil which is normal tool maintenance) dribbled on with a handy little plastic bottle, a recycled little mustard bottle with a nipple on top works well.
