Ryobi 40V HP Brushless 18 in. Chainsaw (Tool Only)

Model number
RY40HPCW01B

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.

§ FAQ

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.

Does this chainsaw have an automatic oiler?

Yes. The RY40HPCW01B features an automatic bar and chain oiler with a translucent reservoir so you can check the oil level without stopping work. Ryobi recommends using bar and chain oil and refilling before each session.

Is there a chain brake on the RY40HPCW01B?

Yes. A front-mounted chain brake is included. It activates automatically in kickback situations and can also be engaged manually, meeting standard safety expectations for chainsaws in this class.

How does the RY40HPCW01B compare to a gas chainsaw?

Ryobi rates the RY40HPCW01B as equivalent to a 40cc gas chainsaw in cutting performance. It eliminates the need for fuel mixing, produces no direct emissions during use, requires less maintenance, and starts instantly with the trigger rather than a pull cord.
