RY40HPCW03K

The Ryobi RY40HPCW03K is the top-of-the-line 40V HP chainsaw kit, combining the 20 in. brushless chainsaw with an 8.0 Ah 40V battery and charger. The brushless motor is rated equivalent to a 52cc gas engine and delivers the fastest chain speed in the lineup at 25 m/s, enabling roughly 100 cuts per charge with the included 8.0 Ah pack. A metal top handle adds structural durability for demanding sessions, while the automatic oiler with translucent reservoir and front chain brake maintain safety and convenience. This is the complete solution for homeowners and property managers who want maximum battery-powered cutting performance without compromise.

§ FAQ

What is included in the RY40HPCW03K kit?

The kit includes the RY40HPCW03B 20 in. chainsaw, one 40V HP 8.0 Ah lithium-ion battery, and a 40V charger. No additional purchases are needed to start cutting.

How many cuts does the RY40HPCW03K deliver per charge?

With the included 8.0 Ah battery, Ryobi rates approximately 100 cuts per charge through 4 in. white oak — the highest cut count in the 40V HP chainsaw lineup.

Why does this kit include an 8.0 Ah battery instead of a smaller pack?

The 20 in. bar draws more power than the 16 in. and 18 in. models, so Ryobi pairs it with the high-capacity 8.0 Ah battery to maintain competitive runtime. The larger pack also provides more reserve for tougher hardwood species.

Does the RY40HPCW03K have a chain brake and auto oiler?

Yes. A front-mounted chain brake activates automatically during kickback and can be manually engaged. An automatic bar and chain oiler with a translucent reservoir is also standard, consistent with all 40V HP chainsaws.

How does the 20 in. kit compare to the 18 in. kit (RY40HPCW01K)?

The RY40HPCW03K offers a 20 in. bar vs. 18 in., a higher gas equivalent rating (52cc vs. 40cc), faster chain speed (25 m/s), a metal top handle, and ships with a larger 8.0 Ah battery vs. 6.0 Ah. It is the more capable and more expensive option, suited for larger trees and heavier workloads.
