Beast Mode
I have a large hickory tree down on our property, large enough I cannot wrap my arms around it. This chainsaw ripped right through it. I can't wait to tackle the fallen oak tress as well.

It starts very well by following the instructions. Very responsive throttle. Next day starts even faster. Great build quality.

    This saw is the real deal! Baddest in it's class!
    Great saw with tons of power! I picked this up after some research and reading reviews. From what I have read and actually seen first hand. It by far, is best in its class compared to the Boss or Rancher. Alot of commercial features also helped me with my decision. Like the magnesium case instead of plastic. This saw is heavy and will definitely wear you out if your working with it for awhile. Better keep a smaller saw for limbing and this bad boy for the big stuff. Haven't had any issues with starting like some of the other reviews. If you have used 2 stroke equipment before, its a no brainer. I have been using the pre-mix gas/oil from Echo. Its expensive, but worth it. Don't even fool with the decompression button as its basically a joke. Other than that, the saw rips. I have already done a muffler mod and it cuts through thick wood in seconds. Definitely recommended this saw for anyone with larger trees or big jobs around the farm/house.

      Another good echo product
      I took down quite a few trees to decide whether or not I actually want to use it milling slabs out. It does it and it does it reliably. I did end up putting a 28in. Bar with a skip tooth considering it is only 60ish cc's. It seems to do well with a longer bar so for the price and not having to spend over a grand on a decent saw, echo made this pretty achievable.

          Hard to get running out of the box but once it runs, it's a beast.
          It took me a bit of time and some swearing to get this saw running out of the box. Once I got it running, nothing could stop it. I ran it for about two hours and put it away until today. It fired right up with the suggested start up procedure and I was able to do another few hours of work with it. This saw is meant to work.

            Works great! I added an aftermarket aluminum base plate and an additional Echo bucking spike, and it has had no problems cutting through 30" fir trees. After doing some research online, I decided to just bite the bullet and buy the Echo 50:1 premix fuel to run the saw. It costs five times what it would if you just mixed it yourself, but from what I've read, the additives in it will help over time to keep your saw running strong.
