12 Inch Brushless Chainsaw - JEXUGK has upgraded the brushless motor to make the medium-sized chain saw more portable and henceforth replace the bulky and noisy mini chainsaw. With a brushless motor that delivers up to 1000W of power, it can handle large trees, logs and small trees with ease. Perfect for ranchers who need to make heavy cuts in the garden, farm or forest, all providing a smooth and precise cutting experience to meet your professional needs 2x4.0Ah High Capacity Battery - JEXUGK decided to ditch the 2.0Ah battery for the sake of continuity in outdoor work and peak power of the electric chainsaw. The 4.0Ah battery doubles the battery life to over 30 minutes (over 120 cuts per charge), the power indicator on the battery keeps track of the power level, the quick charger helps to restore the battery quickly, and the motosierra is compatible with Makita batteries Upgraded Faster And Easier Chain Tightening - JEXUGK has upgraded the moto sierra tightening mode to be more convenient and quicker, which saves up to 70% of the overall time compared to the older models on the market that require an wrench tool to tighten the chain! Three steps to change the chain: 1, loosen the yellow knob counterclockwise. 2, tug the chain outward and tighten the black knob clockwise. 3, tighten the yellow knob clockwise. Tool-less chain tightening will be the future of chain saws 5 Safety Protections - JEXUGK has upgraded its small chain saw with 5 safety protections: 1) U-shape grip handle makes it easier to hold the chain saw during use. 2) Chip guards keep wood chips from splashing. 3) Non-slip textured grips allow for a tight grip. 4) Non-slip, cut-resistant gloves protect your hands. 5) Locking system prevents the tree saw from being opened inadvertently.The ultimate goal of the JEXUGK is for you to feel safe Automatic Oil Filling System - JEXUGK cordless chainsaw with battery and charger has an automatic chain lubrication system, before use, just pour the lubricant or oil into the machine oil storage device, tighten the cover and start the motosierra de bateria, let the mini saw rotate to make the oil fully lubricate the chain, the life of the use of a longer period of time (Tip: every time you finish using the machine inside the oil poured out!)
