    This saw has less then one hour on it. During its first use, ten minutes or so, the saw chain came off and damaged it to the point I had to replace it. (I'm sure it was properly tensioned.) After replacing the chain, I used it today and again, within a few minutes, the new one came off, damaging it where it will not fit into the bar. I did talk to Echo and they said the saw chain is not covered under warranty. Any help would be appreciated.

    What size bar is on this? Are you sure it is being lubricated properly? Hope ya got it from a dealer if so take it back.

    check you roiler turn it up so more oil comes out sounds like not enough is coming out it gets hot dry stretches ruins chain. plus to properly tension loosen the bar then turn the tensioner then tighten the bar.

    How do you adjust the oiler? Thanks for the response.

    I dont know much about the little echos, but I doubt you have adjustable oiler. For chain break in, make sure your bar oiler is working first, then run chain at proper tension for about 3 mins. You will see that it will stretch even doing this under no load. The chain will stretch even more under load and will be even worse with oregon chain. When the chain is new tighten and adjust more often. Also make sure the chain matches the bar and sprocket.

    Oh, just in case. Dont hold it at full throttle for the 3 mins. On and off at full throttle ok. Just dont know how some people would take the 3 min run and lock the sucker up at wot. lol

    if you turn the unit upside down there should be a hole on the bottom with a little screw in it, just turn the screw to adjust you oiler output--it is located about the center of the unit, on the same side as the chain sprocket, and almost in line with it. there is a picture of an oil can with an arrow and a + & - ..adjust accordingly.

    I doubt his oiler is adjustable on that little echo.

    Remove the cover and bar/chain and look into the oiler, start the saw and run just above idle speed to where the clutch engages and see if there is any oil comming out.
