BLACK+DECKER 40V Max Cordless Chainsaw, 12"

I've been cutting wood, most of my life and for primary heat source. I've only ever used a very high quality gas saw, starts with an S. I've cut many trees, as large as they come, all for firewood, - fell, then took all including the tops; nothing left. I've been considering a Batt Saw for a few years and now looks like they reached a level of "real tool". I've only had B+D Batt tools for a while now, - they just seem to work and remain that way; e.g. Screw Gun 20v, Weed Wacker 40v, and not this 40v. I wondered why not 60v, but this is what it is. So, I got the one with the Batt and Charger. Right off they annoyed me since provide the Trickle Charger 400ma output, so it WILL take 4 hours to charge the 40v. The String Trimmer came with the 36-40 1.35a out which is more than 3x's this and yes, would likely re-charge in about an hour. So, plan ahead with time to re-charge or if have another Batt if needed? The quality, upon initial inspection is as - okay/good, "real - tool". (For quick jobs I have an AC Electric other which does well, lots of torque, but the 50ft extension chord unwrapping and wrapping just puts me off sometimes and then let stuff go. And for pruning, e.g. mature Plumb Tree - I thought this would work since a tight space (as trees go), lighter and not Chord pulling. A gas saw of any size, again, just a disincentive to prune. (A "Saws-all" was another option, if not for the chord, and don't want a Batt version of one of those, presently.) So, it's pretty straight forward and the booklet explains it well; and the online support I checked out for the PDF and "other" if there. "Registering" is just giving a Model and Email, - likely verified with receipt if contact directly for support, parts, etc. So, more spam I guess. After waiting 4 hours for the discharged Batt to fully charge, I popped it in and it "runs". Do check the chain tension and know that first. For me, it was to tight. You just don't want sag, firm but not tight. It will hang, stretch pretty quick, so tight - tight makes no sense for the wear on it. I was *not impressed with the "running" part, the spin seems a tad moderate speed for me, and in comparison the AC/electric or 2-stroke Gas. - However, I have not yet cut with it. I realize there's many safety issues with something like this, and no bar brake, but stops spinning when release the trigger. Eh, nevertheless a brake bar that disconnects the juice flow/off switch or actual conventional brake would be appropriate imo. So, cut properly, and to the side of "you". If have no idea, ask someone first or try a online video, etc., or call B+D for some advice. So, with that all said, I'll know in less than a minute if it properly cuts. And again, while the spin speed is a tad moderate, for "pruning" or say, 6-8" "trees", branches, it probably won't matter. I'll assume they thought that all out, and could have made it to any spec. I *will amend/edit this once I've cut with it and see it holds charge. I would be surprised if didn't allow for an hour or so of cutting. And I mean cutting, not looking at the tree for 10 min smoking a cigarette, -- cutting for an hour (like the String Trimmer). For the price, I could just as well have purchased an smallest 2-stroke Gas saw, - so price was no incentive here, - same price. I do like that they mention the preferred vegetable oil for chain lube. I'd prefer the Manual Oiler on the 40v, since may not "leak" when stored? But, it is what it is. They cite 30 weight which in the summer is "like" as one reviewer said, any cooking oil. It's not spinning fast enough to do as I've seen, - "blue" the steel bar if even properly oiled (just plain hot from 8 hour day use. So, I'll give that a shot. Otherwise your regular non-detergent general 30 weight, nothing special oil is all one needs. So, that's it for now. I'll be back, and you'll see an "edit" at the top. Far more brief - then. I hope that helps folks. Again, - don't think this is a toy, - ask someone how to cut stuff. That no chain bar brake bothers me, as commented. I've seen folks "hold on" tight, when you'd think they'd just let go, and do not. The trigger is pretty stiff with no "Lock-on" and I see why, so expect your finger to get tired! hahhh! Always a compromise.
