Query: buyer Beware

This is the worst saw ever. The chain will not stay tight. As with other reviewers I can cut for about 10 min and then spend 10min adjusting the chain. It takes hrs to do a small job. If you do buy this saw make sure you adjust the chain with gloves because the muffler is right next to the chain ensuring you will add burning your hand to your frustration. I know this sound crazy but after putting the chain on a dozen times in an hr you get a little impatient and the next thing you know your hand is burnt. If you can keep the chain on the motor runs fine and is easy to start. This is a big If.
