The RYOBI 40V HP Brushless 18" Chainsaw Kit delivers more power than a 40cc gas chainsaw, making it a true gas replacement. 40V HP Technology combines a powerful brushless motor, advanced electronics, and high performance lithium technology to provide more power, runtime, and durability. With over 90 cuts per charge and a premium full house chain, the saw delivers longer runtime and faster cutting. Experience gas performance with just the pull of a trigger, without the hassle of gas, cords or maintenance. The 18” bar and chain tackles cuts up to 32”, making it ideal for felling, bucking, and limbing. Using the combination wrench conveniently stored on the tool, precisely adjust the chain to the desired tension. This chainsaw has an automatic oiler to keep the chain lubricated for longer chain life and an added mechanical chain brake for kickback protection. The variable speed trigger gives you maximum control during any application. Best of all, it is part of the RYOBI 40V system where any 40V battery works with any 40V product. This 40V HP Brushless 18” Chainsaw Kit is backed by the RYOBI 5-Year Manufacturer's Tool Warranty, 3-Year Manufacturer’s Battery Warranty, and includes RY40HPCW01 40V HP Brushless 18” Chainsaw, OP4060A1 40V 6Ah Lithium Battery, OP406A 40V Rapid Charger, Scabbard, Combination Wrench, Carry Case, & Operator’s Manuals.
