chains that come loose that fast , and is not a cause of a weak bar bolt slipping , for sure is caused by improper oiling of chain and its overheating , heat makes metal expand so chain goes slack if it gets hot
The only time I saw this was when the saw was run with the chain too loose. The chain should be snug al the way around the bar. If it is run loose for too long the chain will develop burs on the driver links. Now the driver link will not fit in the groove on the bar so the chain is tossed off. Replace with a new chain
If the chain keeps coming lose it can be down to a number of things, inadiquate oil to the chain, incorrect type of oil in the tank, poor quaility chain, worn sprocket and or guide bar.
Hi luvmylife63.
If you have the proper tension on the chain against the bar and the chain is coming loose right away then you need to replace your chain and/or the bar for your chainsaw.
Please take time to rate me
The chain adjuster does not actually hold the guide bar, that is done by the bar nut/nuts, the main reason for chains coming lose is inadiquate chain oil to the bar/chain, does the chain look dry? it can also be the result of what you are cutting, if it is very dirty timber or railway sleepers.
Your chain is too loose or it is worn out. Adjust the tension on the chain. The chain should not hang away from the bar but should be loose enough that you can pull it away from the bar with not much effort. Adjust the tension until it is set correctly.
The most likely cause is a loose chain. Chain Adjustment
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.
Continue holding the nose of the bar up & tighten up the bar nuts / bolts / quick-release system.
The inside part of the chain are called drive links. I think when the chains came off the first time (loose chain?) some of these links were slightly deformed (burred). Take a flat file to the burrs on the sides of the drive links. Once repaired keep your chain properly tensioned.

Lou If no burrs please repost. This has piqued my interest. I think a brand new chain will operate correctly.

If necessary, loosen the nuts that are clamping the guide bar in place (or whatever your saw uses to hold the side plate and bar on with). We don't need these really loose - just finger tight will do.

Now, while holding the nose up, adjust the tension so that the chain just touches the underside of the bar.
