      Q:The chains on both my 40V 14" Chainsaw and 10" pole saw have already stretched to the point where I cannot use them. bought an extra chain for each, can a Link be removed so I can keep using them or do I have to keep buying new chains for both.

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

            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.

              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.

                Outstanding Performance and Value
                [This review was collected as part of a promotion.] This saw is exceptional. I have been cutting 16” diameter limbs and the saw never struggled. The power and torque is better than on my previous gas powered units. I would highly recommend this saw.

                  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.

                    Perfect for a home owner but not a firewood saw
                    I have cut a lot of wood with it and also own 3 gas saws. This is an impressive saw but not ready to replace gas saws for firewood (and not referring to the run time). The narrow kerf chain allows this to cut efficiently but keeps stretching a LOT under heavy work and sometimes it jumps off and gets bent quite a bit (being so thin) and that could be the end of it unless you work on it to restore. You could possibly replace bar/chain but at a power loss. I hope the next version is more powerful.

                      I'll never use gas again
                      Another great Ryobi tool!! I made one mistake, out of the box, I did not tighten the chain bar bolts before use and the chain came off the bar, ruining the chain. I ordered new chains, set the tensioner and tightened the bar bolts and now all is good. This saw is amazing! The battery has plenty of power to work for about 45 minutes to an hour (see photo). I purchased an extra battery. So, do yourself a favor: 1. Read the manual 2. Verify that all bolts are tight before using

                        Powerful and well built
                        Saw runs great! Has more power than my 18inch gas Poland saw. I mainly use it for cleaning up branches or cutting up small to medium logs for firewood. Nice not to mess with pulling a cord to start the saw when you only have 1 or 2 cuts to make.

                          great for small projects
                          bought the saw tonight to do some clean up on a few trees that we fell. the saw cut great. I thought the battery would've lasted longer but got through what is shown in the picture in one charge. my only complaint is that the bar oil reservoir leaked pretty bad. I thought maybe it wasn't seated correctly. I unscrewed and made sure to put it on straight but still had problems with the leaking. I'll try popping and extra o-ring in it tomorrow and see how it does.
