This saw is absolutely amazing. I’ve cut oak whose diameter is larger than the length of the saw and the saw didn’t hang up.

Saw really cuts great, powerful and easy to handle. Using the ARC 8AH Batteries. The speed set feature I thought would be worthless, turned out to be great. What I found is a lower chain speed actually cut through certain logs faster (probably from preventing the teeth from bouncing over the wood). I had no trouble with the batteries overheating. This was probably due by having the chain properly sharpen and not forcing saw (very little downward pressure needed).

I do like the saw. It had plenty of power,and with a new chain, it cut right through 18” red oak rounds. But I would say , after about 15 minutes of continuous use the 10 ah battery did overheat. I popped in another 10 ah battery and it happened again. I have the 18” saw also, and I don’t have the same problems,and that’s using the same 10 ah batteries. Any feedback on why the batteries overheat would be appreciated…

I just got done cutting down a 20" choke cherry. I used the CS2000 to cut the tongue and groove notch. Then I finished felling with a CS1800. Both saws performed admirably.
THEN I started cutting up the trunk with the CSX5000; and I didn't get very far before the 12ah battery overheated. So I swapped it out with the 8ah battery that came with the saw.
I didn't get very far when the saw itself overheated!
It was now out of commission. Luckily I had the 2000 with me to finish up the trunk; although still overheating the battery.
