Let's be honest: we men (and the women who guard the garden plots) are conservative. It seems to us that the louder the engine roars and the more the exhaust stinks, the more serious the work. But this is from the series "measuring ... with a ruler". Modern technology has gone so far that it can give you a thousand watts of pure, silent power powered by a small plastic box with lithium inside. And today we will analyze the very thing that turns cutting wood from a punishment into an almost meditative hobby.
Meet the hero of communal battles and suburban construction projects — the battery chainsaw BORT BKS-2112-LI. I warn you right away: this beauty is sold without a battery and charging. This is not a disadvantage, it's a deliberate move, which we'll talk about later, but it sounds like "a motorcycle is sold without gasoline." And it makes a devilishly pleasant economic sense.
A kingdom without sockets, or why wires are evil
Do you remember the iconic scene from "A Very scary movie" where the heroine runs away from a maniac, and the vacuum cleaner wire treacherously ends? It's the same story with wired tools, only you don't run away, but you try to reach the top branch of an old apple tree. An extension cable of 50 meters plus a carrier. You pull this electric "serpentine" through the strawberry beds, it clings to every currant bush, tries to throw it off the stairs and is sure to pull out of the socket at the most crucial moment, when the chain has entered the knot only half.
Battery technology is a breath of freedom. You just pick up a tool and go to war with the undergrowth. We parked the car in a wooded area, took a saw out of the trunk and sawed wood for the barbecue. Without searching for a generator, without cursing the country wiring, which "knocks out the plugs" if you turn on the kettle and the saw at the same time. Autonomy here is not just a characteristic, it is a philosophy.: You're not tied to anything except battery life.
Hungry beaver inside: disassembling the "flame engine"
The heart of this "toothy" is a 1000W brushless motor. Let's translate it from technical to human. What are brushes in old engines? These are small charcoal sticks that rub and spark, turning your drill into a mini fireworks show. Over time, they wear off, the tool loses its speed, and you go to the service. The brushless motor (in the engineers' slang — EC motor) is devoid of this drawback. Nothing is rubbing except your palms from pleasure. The energy from the battery does not go into heat and special effects with sparks, but directly into torque.
What does this mean in practice? And the fact that this unit bites into dry acacia or wet poplar as if it were a "Sliced" loaf. 7.8 meters per second is the speed of the chain. Imagine that this animal runs almost eight meters along the trunk of a tree in the time it takes you to take one breath. Idling — 3500 revolutions per minute — keeps the chain in good shape, ready to launch an attack at the first pull of the trigger. And most importantly, silence. Only the rustle of falling sawdust.
The magic of the platform: how I stopped worrying and fell in love with Makita
Now the key point about the configuration. The saw comes without a battery and charger. It sounds like "sugar-free coffee," but let's look at the benefits. This saw is compatible with the legendary Makita 18V LXT system. It is a standard, like USB Type-C among smartphones. If you or your colleagues already have a screwdriver, hammer drill, grinder, or jigsaw on this platform, you already have a ready-made power source.
You don't pay for an extra battery that will gather dust in the case. You buy a "naked" device (in English it is beautifully called "body only") and put on it the battery that you already have. Do you need to work longer? You have two or three batteries of different capacities. While one is sawing, the other is charging. This is an endless conveyor belt for turning roundwood into square firewood. BORT's related batteries range from lightweight BA-21Li for short cuts to monstrous BA-21U-93 to cut timber on an industrial scale. Choose according to your hand and task.

Why your back will thank you, or the art of being light
Gasoline monsters have one unpleasant feature — they are heavy. Even an empty chainsaw with a 12-inch tire pulls 4-5 kg. Add a full tank of fuel and oil here, and you already have a small weight in your hands. After an hour of handwork, you hug a tree not because you are an eco-activist, but because they simply refuse to rise.
BORT BKS-2112-LI weighs only 2.7 kg. This is the weight of two bottles of good wine, which is evenly distributed in the palm of your hand. You can use this tool at a height, standing on a stepladder, with your hand outstretched to a capricious branch, and not be afraid that you will be pulled down by centrifugal force. The balance is adjusted so that the weight of the tire and the body do not outweigh each other. The saw does not act like a rough tool, but like an extension of your limb. The light weight will be especially appreciated by those who are forced to "mow" the shoots vertically on a construction site or in public utilities, holding the device literally at shoulder level.
The brake, fractions of a second and the instinct of self-preservation
Safety is something we remember when it's too late. But the creators of this "shredding thing" took care of your fingers and limbs in advance. The saw has a instant chain stop. As soon as you release the trigger, the chain freezes in place. He doesn't run out by inertia, he doesn't crawl lazily, threatening to saw through your pants. No. Stop.
The second guardian of your health is the mechanical brake of the chain in the form of a front flap. It works the same way as airbags in cars. If there is a rebound and the saw sharply "pecks" upwards (this is called a kickback), your left hand instinctively hits this shield, and the chain goes into a "knockout" in 0.1 seconds. This is an escape from injuries that are described in very unpleasant words in logging textbooks. Here it works at the level of reflexes, as if Gandalf himself is shouting at you: "You won't get through!"
Lazy maintenance: lubrication and stretching without a hammer
Previously, the chain saw maintenance process resembled a shaman's ritual. A special key, an attempt not to drop the nut into the sawdust, adjusting the eye tension, skewing again. Here, engineers have clearly spied on lazy geniuses. A quick chain tensioning system has been implemented — a regular lamb on the body. You turn it without any tools, tightening the chain to the desired ring.
Have you run out of lube? You won't remember it by the smell of burnt metal. The saw itself supplies oil to the tire during operation. Your task is to top it up in a transparent tank with a volume of 0.11 liters and do not forget about it every half hour of intensive kneading. By the way, a recommendation for harsh Siberian everyday life or winter emergency work in housing and communal services: pour low-temperature oil, and no frost is terrible. The mechanism does not turn brown, the slurry does not freeze — an ideal layout for outdoor work in any season.

Hidden talents: a sawmill that fits in a closet
A 305 mm tire (12 inches in a non—metric coordinate system) is the golden mean. You won't go felling century—old redwoods with this baby (although who knows?), but it's perfect for building a country toilet, a sauna, a gazebo, or cutting neat logs for a fireplace. The diameter is up to 30 centimeters in her teeth. A chain with a 3/8 pitch and a 1.1 mm tooth is a real shark. Forty-five teeth simultaneously dig into the wood and spit out the shavings as if there were a lumberjack competition in the yard.
An interesting profit for Commerce: land clearing. Crews who leave for emergency felling or deadwood harvesting in city parks will appreciate the lack of wires and immediate readiness for work. You can carry it right in the cockpit of the Gazelle, because it doesn't stink of gasoline. The cover is included, so there are no oil stains on the seats. They took it out, pressed it, cut down the interfering branch, threw it in the trunk, and went on to fix the world.
Instead of a conclusion: the precepts of a seasoned sawyer
This text is not a purchase instruction, but rather a story about how technology allows us not to suffer. BORT BKS-2112-LI is a representative of a new school of tools that do not require you to have an engineering degree to launch and a weightlifting sports category to carry. It's just a damn powerful, quiet, and instant-to-use device. It won't replace the gym, but it will give you a head start on any cardio in the fresh air.
And yes, when you go out to the site next weekend, pick up this tool and start turning a pile of branches into a neat woodpile with a light whoosh, do not forget to smile at the neighbor who is looking out of the window. Smile at him. Now his dog sleeps peacefully, his children have not learned new words, and you are a hero who handles wood as elegantly as a sommelier with a corkscrew. Just make sure that all your batteries of the Makita 18V LXT system are charged. That's the only thing you should worry about now. Well, and about where to get more trees for such pleasure.
