If you're having trouble with your chainsaw chain getting stuck, there are a few things that could be causing the problem. First, make sure that the bar and chain are properly lubricated. If they're not, the friction can cause the chain to get hot and sticky, which will cause it to seize up. Secondly, check to see if the bar and chain are properly aligned. If they're not, the teeth on the chain will catch on the wood and cause it to get stuck. Finally, make sure that the saw is properly tensioned. If the chainsaw is too loose, it will sag and cause the chain to get caught on the wood.
