Enter the RYOBI 40V System with the 40V HP Brushless 20" Chainsaw Kit. 40V HP technology delivers more power than a 50cc gas chainsaw, making this chainsaw a true gas replacement. This chainsaw gets over 100 cuts per charge and is equipped with a premium full complement chain. 40V technology combines a brushless motor, advanced electronics, and high performance lithium technology to provide more power, longer runtime, faster cutting, and greater durability. The 20” bar and chain tackles cuts up to 36”, making it ideal for felling, bucking, and limbing. This chainsaw has an automatic oiler to keep the chain lubricated for longer chain life and an added mechanical chain brake for kickback protection. Adjust your chain for controlled, clean cuts using the tooled chain tensioning with on-board tool storage. Best of all, it is part of the RYOBI 40V system where any 40V battery works with any 40V product. This 40V HP Brushless 20” Chainsaw Kit is backed by the RYOBI 5-Year Manufacturer's Tool Warranty, 3-Year Manufacturer’s Battery Warranty, and includes RY405011 40V HP Brushless 20” Chainsaw, OP4080A 40V 8Ah Lithium Battery, OP406A 40V Rapid Charger, Scabbard, Combination Wrench, Carry Case, & Operator’s Manuals.
