Answer This Question

the btl has a speed of 22 which is about 50% more ( speed 14.2) than the w02k. so maybe a more powerful motor or geared differently

By|Nov 8, 2025

    Hello, Kevin - The RY40HPCW02 is a newer model than the RY40505. It is more powerful than the RY40505, and you will get more cuts per charge with the RY40HPCW02. It also features metal bucking spikes for kickback protection and an improved automatic oiler to reduce oil leakage. If you need further support, then feel free to ask another question.

            I'm doing 10-12" pine and about 12 cuts uses 1/2 of a 4 amp battery. Not sure what that 80 cut tree species is or it's diameter. If you are going to do much cutting have two batteries and time to cool them down. The charger enforces cool down.

                      Powerful, Easy to Use, and Great for Homeowners
                      This was my first chainsaw, so I was looking for something that was powerful but also easy to use. After using it for several months, it's exceeded my expectations and has given me a lot of confidence tackling tree maintenance around my property. I've used it to remove large branches from a lilac tree that had grown over my garage, trim thick limbs from a dogwood tree to open up the walkway to my front door and make mowing easier, and cut up fallen trees in my backyard into manageable pieces. It has handled every job without any issues and has had more than enough power for everything I've needed it to do. One of the things I appreciate most is how convenient it is. I don't have to deal with mixing gas, pull-starting an engine, or routine maintenance. I can install a battery, pull the trigger, and get right to work. The chainsaw also feels well-balanced and easy to control, which helped me feel comfortable using it even though I was new to chainsaws. Overall, this has been an excellent addition to my 40V collection. If you're a homeowner looking for a dependable chainsaw for storm cleanup, pruning larger trees, or general property maintenance, I would definitely recommend this model.

                        [This review was collected as part of a promotion.] I was unsure about buying a battery powered chainsaw but I’m glad I did. This chainsaw is a beast.

                          Returned the first saw since it leaked ALL of the oil out, all over my floor, the first night. After the replacement arrived, I studied the Users Manual WITH A MAGNIFYING GLASS. (Yes, it is very small type.) I found a reference to an "oil adjustment" screw. It is not prominent on the bottom of the saw. I recommend that you find it and be ready to adjust it, if the oil leaks out when not being used.

                          [This review was collected as part of a promotion.] Worked great for pruning my two large maple trees and cutting the branches down for firewood. The chainsaw cut through everything with ease. Only used half of a 6ah battery in 4+ hours of work.

                            Great to use but quickly leaks oil everywhere
                            I have other Ryobi 40V tools and needed a larger Chainsaw to clean up some large tree debris. I own another chainsaw and understand they leak, but not like this one. I purchased this after reading reviews. I should have searched "leak".There are lots of reports of oil spilling out of the reservoir, regardless of the amount or how tight the cap is. It's like there is a breach in the oil reservoir. I am interested in getting support from Ryobi to see what I am missing.

                              It's always nicer to have a larger chainsaw for bigger pieces!! This Ryobi 40-volt, 16 inch is more than enough to get the job done!! This chainsaw is lightweight compared to my 14 inch and is very well made!! This one cuts a lot of wood fast!!

                              Chain won’t stay on.
                              I was so excited to get this. I used it 4 times. Each time I drove almost 2 hours each way to my camp for nothing. I could not get this chain to stay on longer than 3-5 mins. No matter how many times I take it apart clean it and adjust the screw. Most the time it falls off even before I can use it. Never had that issue with my gas stihl. Leaks oil bad too and mines stored in My house. Less than hour used. I wasted $600 on this machine I would stay away if reliability matters. It cut pretty decent but I’m definitely going back to gas. I wish I had my receipt.

                                Best Decision Ever
                                [This review was collected as part of a promotion.] I bought this about a month ago and I am so happy that I did. I had a few trees that I needed to take down that were dead, and this thing just kept going. With a 6ah battery, I was able to cut down 1 tree and completely chop it up. It was completely flawless. I did upgrade to an 18" Oregon chain and bar, which was a perfect fit. No more messing with gas, no more pulling a string and messing with the choke. This thing works well and I highly recommend it.
