    A:  I recommend Oregon or Echo chains for that reason... My Ryobi chains did the exact same thing...

            lots of power
            [This review was collected as part of a promotion.] This will replace my gas saw. Very impressed with the power and the battery life. The battery also charges really quick. No fumes and low noise compared to gas saw.

              Wish I had done this sooner
              [This review was collected as part of a promotion.] I tend to cut small to medium trees on our property, along with the odd larger one. My lawn mower died, and based on recommendation from my brother, purchased the Ryobi 20 inch 40V HP. I was so thrilled with it that I sold my gas trimmer and bought another Ryobi. Then my wife asked me to cut down a couple of trees on the side of the house. I immediately put my 2 gas chain saws up for sale and purchased this, the 40V HP 18 inch. Hindsight is 20/20, I should have done this long ago. It may only be a bit lighter than my gas model, but makes working in the woods so easy. I was able start and stop at will, as I cut branches in order to fell the tree. It is so much quieter and generates no fumes. With no engine vibration, I had a better feel of the tree. I no longer need to store containers of fuel, and mix in oil, nor drive to the gas station 15 minutes away. As I am trying to stay in the 40VHP ecosystem, I have several batteries to pull from, so one can be on charge while another is at work. All that remains is to try larger trees, but I must say that at present, I am thrilled. Ryobi seems to suffer from a lack of respect by many tool users. It is highly unjustified. I have a more expensive brand in the city, and am not sure that it is any better in either build quality or function. To quote Mando, "This is the way."

                Great on small diameter trees
                [This review was collected as part of a promotion.] I bought this saw after we had a couple bad storms that knocked down trees and limbs. It does great on 3 to 4 inch limbs and trunks anything bigger and it wears battery down fast. One Sugar Maple about 18 inches in diameter and a fresh battery charged overnight barely makes it through one cut.

                  Plastic Junk
                  This chainsaw worked great until the other day when the chain slightly got stuck while cutting a tree. The chain came off the bar, so I opened it up to check out what was going on. After about 2 minutes I realized the only thing holding this entire chain and bar together is a bunch of tiny pieces of plastic. When the tree caught, the cheap plastic holding it together exploded and is not repairable. There's almost zero warranty on these things after the first 90 days and good luck finding parts.

                    Awesome saw.
                    [This review was collected as part of a promotion.] Bought this chainsaw back in the fall(oct) of 2022. This guy is a beast. Cuts thru logs with no problem. I even had some logs around a 24”-26” diameter. No problem cutting thru one side, then rolling the log and cutting thru the other. The saw has some nice weight to it, pretty balanced, and doesn’t clog up with the sawdust. Keep the blade sharp, and you’ll have no trouble cutting thru even the hardest wood.

                      spend more, buy better.
                      bought this saw with high hopes, but can't run for more than 3 minutes without the battery overheating. I bought this for hurricane season so I did not have to mix fuel anymore. very disappointed. Might spend the money and buy the Milwaukee.

                          Good but fatal flaw…
                          Third 40v Ryobi chainsaw. This one is much better than the previous version, that had a flaw in sprocket design. This one is powerful, balanced and well built, except for the under-designed chain tension bolt plastic casing. The plastic housing cracked/broke after tightening the chain while the housing’s lockdown nuts were semi-tight, the typical way. This breakage allows the bar to side and thus the saw is mostly unusable until fixed. Ryobi should make this saw ‘tool-less’ too.

                            Love it
                            Unboxed and immediately charged the 5AH battery which took less than an hour. Grabbed my 4AH battery as well that i use for my string trimmer. Filled up with bar oil. The cap does need to be tight to help prevent leakage that everyone complains about. It's a chainsaw! They will get dirty with oil and grime. Yall need to get over it. I have an extremely large oak tree trunk that needed to be cut in 18" segments. The trunk measures 30" to 36" diameter and 22' long. The 5Ah battery was able to get through one side cut before hitting the thermal cut-off. Battery got too hot. Jumped to the other side of the long with the 4Ah battery. 1 full cut both sides complete. The 4Ah battery did struggle a bit but got through it. That battery overheated as well. Not upset about it. Two hot batteries and now im waiting for them to cool. Threw em in the freezer for 10 min and i was back in business. The 5Ah battery is now showing 3 bars and the 4Ah battery has 2. Batteries are warm so i made another cut on the massive log. Saw cuts and powers through with ease on the 5Ah. The 4Ah doesn't drive the chain as fast. Smaller battery. So the minimum AH battery needs to be 5Ah. Im going to buy the 6Ah battery soon. I do know the saw isnt designed to cut logs near 3' foot diameter but why not try right? I was burying the bar in the trunk too. I was able to completely cut up that huge trunk. I was impressed really. Pop in a battery and fill with oil and your cutting! That fast and easy. I did cut normal 16" diameter logs and was able to get a good 10 cuts in before the 5Ah battery hit the thermal cutoff. That was ok because i have an extra battery. Cut some more. Too be honest, the cordless battery saw lasts about as long as i want to before i want to stack wood and keep my work area tiddy. Take a break! Not a bad deal here. I have over 2 acres and i forecast that this saw will treat me well. Hope this review helps yall.

                            Great saw but....
                            [This review was collected as part of a promotion.] The saw worked great,however, all 3 saws (after exchanging each) leaked lube oil badly if left filled overnight. I will purchase again when the issue is resolved.

                            Hello, Altadutch - We are disappointed to learn that you were not pleased with this saw! Given the nature of chainsaws, it is normal for oil to seep from the saw when not in use. To prevent seepage, empty the oil tank after each use. When storing the unit for a long period of time (three months or longer) be sure the chain is lightly lubricated; this will prevent rust on the chain and bar sprocket. We hope this helps! And if you'd like to discuss your experience further, then please feel free to email us anytime at Reviews@RYOBItools.com.
