The Ryobi RY40HPCW01B is a 40V HP brushless 18 in. chainsaw designed to replace a 40cc gas saw without the fumes, pull-cord, or fuel mixing. The brushless motor drives an 18 in. bar and delivers roughly 90 cuts per charge when paired with a 6.0 Ah 40V battery (sold separately). An automatic oiler with a translucent reservoir lets you monitor oil level at a glance, and the tool-free chain tensioner and bar tightening knob make field adjustments fast. A chain brake provides an added safety margin during kickback events. As a tool-only SKU the RY40HPCW01B is the right pick for owners who already have 40V HP batteries on hand.
What bar length does the RY40HPCW01B use?
The RY40HPCW01B uses an 18 in. bar, which is suitable for felling small-to-medium trees and limbing larger ones. It is the mid-size option in the 40V HP chainsaw lineup, sitting between the 16 in. RY40HPCW02B and the 20 in. RY40HPCW03B.
Which batteries are compatible with this chainsaw?
The RY40HPCW01B is compatible with all Ryobi 40V HP lithium-ion batteries. Ryobi rates approximately 90 cuts per charge with a 6.0 Ah 40V HP battery. Larger packs such as the 8.0 Ah will extend runtime further.
