Saw could be improved by speeding up chain or adding more teeth to limit bucking.
After buying a battery powered pole saw that I was extremely pleased with I bought this as a light weight replacement for a gasoline powered trim saw. I was really disappointed when out of the box it cut really slow and bucked like a banshee. I inspected the chain and realized it had twice as much distance between the cutting teeth as my other saws as well as some anti kickback limiters. I realized that is why it was cutting slow and bucking so bad that it was causing pain to my body. I ground down the kickback limiters and shortened the depth gauges on the teeth and that helped tremendously with bucking as well as speeding up the cutting action. I am going to replace the factory chain with a commercial chain with twice as many teeth and see if that further limits the bucking action and improves the cutting action. The saw really needs to spin the blade faster in my opinion as well.

Easy To Use
Amazingly useful tool for yard and garden work
Amazingly useful tool for light to medium trimming and cutting down brush, small trees, etc. Not having a gas engine or power cord to hassle with makes it far easier to use. It being a chain saw, albeit only 12", it does draw a lot of power so I recommend the 146WH battery.

Great tool for cutting small branches.
So far the chainsaw has worked just great. Have not run out of power well trimming bushes with branches up to 2 inches in diameter.

I use this little saw all the time saves time & gas
Always have to cut and pick up branches around my fence line. saves having to carry gas and the bigger
chainsaw. Never had a problem starting either.

awesome cordless chainsaw
I purchased this saw to bring on jobs to trim limbs from trees, remove dead branches and to clear brush for new planting areas. Works just as well as a gas powered saw but with no fumes, no fuss with bringing gas and not worrying about in not starting or flooding out. I was surprised how long the charge would last on the battery after using it non stop for about 6 hrs without giving the battery an extra boost. Still have one dot left and one dot will still cut down a 12 ft tree with a 10" caliper and cut everything up into 4 ft peices. I think I will at some point purchse the 16" blade to cut some larger material. Love the fact that it has the built in chain tensioner. Wish all chainsaws had that. I previouly owned the Black and Decker chainsaw and it is like a child's toy and now it is junk after using it for a few months. No comparison what so ever.

Chainsaw has plenty of power
First time use revealed a lot of torque for a 40V battery. Furthermore, very light weight allows for less arm fatigue. This is a very good light duty chainsaw for small jobs. I was able to go through 5" limbs with little effort. I had to tighten chain only once during job and it was easy.

Good power and run time !
I was a bit skeptical about a "battery" chainsaw, as earlier ones were a joke with battery life for only one or two cuts. This one is clearly of the "next generation" and has adequate power for it's 12 inch bar size. It is handy for dealing with "slash" from downed trees, but is too small to fell anything over 4 or 5 inches diameter. Run time with the 40 volt battery is good for 100 cuts or more. The only issues I have with the saw are: 1.) the trigger safety lock is a bit inconvenient compared with similar ones on gas powered saws (but this is probably because the saw can start so quickly), and 2.) as delivered from the factory the saw chain was installed backwards (which does not inspire confidence in how well the rest of the saw was assembled) So far, however, no problems.

does this item come with charger & batteries?
Joe on Dec 25, 2013
BEST ANSWER: This is a Bare Tool - Batteries and Charger Sold Separately.
I ordered this saw and when it arrived the factory box does NOT have the words GMAX on it. There is a paper sticker on one end of the box that does have GMAX on it. Which is correct? Which saw do I have? I did not want to open the factory sealed box in the event I had to return the saw. I also bought GMAX Hedge trimmer (40 vt) and expected to use the charger and battery on the saw.
