Enter the RYOBI 40V System with the 40V HP Brushless 18" Chainsaw Kit. 40V HP technology delivers more power than a 38cc gas chainsaw, making this chainsaw a true gas replacement. This chainsaw gets up to 168 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 18” bar and chain tackles cuts up to 32”, making it ideal for felling, bucking, and limbing. This chainsaw has an adjustable automatic oiler to keep the chain lubricated for longer chain life and an added chain brake for kickback protection. Adjust your chain for controlled, clean cuts using the tooled chain tensioning with on-board tool storage. Recharge your 40V 5Ah battery in less than 50 minutes with the included 40V Rapid Charger. Best of all, it is part of the RYOBI 40V system where any 40V battery works with any 40V product.
