Because of its design, the DCCS620 is normal, however there are a couple of things that you can do to prevent oil leakage.
- Empty the oil after using it. Store this chainsaw without any oil in it, so it won't leak while not in use/stored.
- Use an O-ring on the oil cap:
- Remove the oil cap completely from the chainsaw.
- Use a 5/8 or 3/4 o-ring and put it into the indentation of the cap. You might need some pliers to stretch the o-ring
- Once it fits perfectly into the indentation, lubricate it a little bit with some oil and put the cap back onto the chainsaw. Please make sure that it fits all the way in, as it should.
Please notice that lubricating the o-ring with some oil after it's into the indentation can help to put the cap in place without forcing it too much.

Agreed, that’s why I stated this string. The leaking is awful messy!
Yes, thanks much for the YouTubers who included great videos. It is also a shame that DW suggest using an o-ring when there is already an o-ring in place. It you put your finger into the oil filler, you will feel the o-ring. What BS from a reputed brand - well, I thought they were.
Based on the YouTube video, you can see the poor manufacturing quality of the oil tank. Baffles me that DW simply does not address that issue and release a rev1 model - like what any other manufacturer worth its salt would do?
So here's a thought… buy it from Home Depot or Amazon. When it leaks, just return it. The returns go back to DW. When the units start to pile up, either DW will have to address the issue and/or the resellers will not carry them until DW takes action.
The really annoying thing is that it would take DeWalt about 5 seconds to fix the problem during the manufacturing process. All the assembly guy would have to do is squirt permatex (or similar) around the ports on the tank when he is putting the saw together and problem solved…
I did send the first one back. Right out of the box, I had filled it with oil and put it in the back of my Gator, for work the next day. The next day I came out to find the Gator bed full of oil…..
Only because of the battery compatibility issue (uses the same as many of my other tools) did I order a second one. That's the one that I disassembled right out of the box and permatexed the ports…There's a raised seam where the 2 halves of the tank are fused together, so the connectors do not seal properly. Just takes a little permatex to fix it (and an hour to take it apart and put it back together)….
So, I had to get a chainsaw and given my investment in batteries, and the fact that I found a good deal going, I ended up with this chainsaw. However, in line with all the comments provided here, prior to putting any oil in, I followed the YT instruction and sealed all the potential leak spots. Result NO LEAKS! So, here some concluding comments:
1. If you buy this unit, follow the YT (https://m.youtube.com/watch?v=DOcs38FmNJw) instructions and seal the crappy oil tank (before having to deal with the mess with oil). The instructions are great. Yes, it would have only taken DW 5 minutes to resolve but it will take you about an hr., esp. when doing it for the first time and tube of gasket sealer (from HD - $8).
2. Shame on Dewalt (DW) that they have not addressed this issue esp. when there has been so many comments on their own website. Double-shame on DW as the guidance Dewalt provides about using an o-ring to stop this leak is false. There is already an o-ring provided as part of the design of the cap. The oil does not leak from the cap! Not sure what Dewalt's objective here is but it is misleading and not what one expects from DW.
3. Massive thanks to Papermoongarage for doing the YT video
4. DW should track down the YouTuber who provided the video (@peppermoongarage) and pay him a handsome amount of $s for preventing a whole bunch of chainsaws being returned to DW.
Finally, once again, thanks to Papermoongarage!
AJ - great comment and suggestions. DeWalt's “solution” is to drain the oil after every use……hurts my head..
Yeah..This thing leaks ALL the oil out if you store it with oil in. Draining the oil is a ridiculous suggestion. What, are these people stupid??? Their suggestion to put an O ring in does not work. There is no room for one even with the slot, unless it is some special type of dimension Oring…In which case…WHY DOES IT NOT COME WITH ONE???? And not only that, the plastic retaining clip breaks when you take it out of the oil tank!!!!!
Do not buy this tool. Made in CHINA, so say no more.
Nigel Smith it does come with an Oring. Its just not on the cap its in the neck of the oil tank. Dewalts own parts diagram shows this and even has a part number. But yet there own tech says put an Oring. Take the oil cap off and look into the neck where the oil cap goes you will see the Oring. The neck is black and so is the Oring buts its there. Which is kind of useless because it does not leak from the oil cap anyway. I have told others you literally store it with oil cap facing down because it leaks from the opposing side. I have been doing this since I bough as someone else had suggested. Mine is full off oil and I have had it for a year and it does not leak. The occasional drop or two but I store it cap down on a rag. The is dry!
AS I posted before, mine leaked from ALL the ports on the oil tank. Disassembling the chainsaw and putting a little permatex on all the ports fixed it. DeWalt could have done that during the assembly process in about 10 seconds. Instead, I had to spend an hour or so to fix THEIR problem. The problem is that the oil tank has a seam where the 2 halves are bonded together. That seam prevents a good seal (without permatex), so you get leaks.
Just joined this group. DEWALT DCPS620B 20V MAX* XR® Brushless Cordless Pole Saw just over a year ago and because of back problems I only just started using it (September 2024). It works great. But I immediately ran into this problem of the oil leaks you all are talking about.
I have had to prune back a tree both because it was growing tall enough to shade my solar panels and because in California the insurance companies are looking for any excuse to cancel our policies. But when I stood it up between cuts, when I laid it down on one side or the other, it did what you all have experienced. Strangely, when I prop the motor/chain part on a 4x4 block of week and keep the oil reservoir level, it does not leak.
I have read all your comments and I am prepared to disassemble the head area to use Permatex to make the repairs, but there are several Permatex products out there. And I have tried to find a YouTube video for this pole saw without success. It would be really helpful if any of you would 1. ID which Permatex product to buy and use and post a link to the YouTube video you say that shows how to make this repair.
I too have been buying only two brands since the bloody batteries are so expensive. I have been really happy with Dewalt products for their performance from my Dewalt “Skill” saw to an off brand small vacuum stick that nevertheless uses Dewalt batteries. Since the pole saw is over a year old, I am happy to make repairs, I just need to be shown how to make them. Thank you all for your help and suggestions.
Peter D'Aprix AJ's post from 1 month ago has the link to the video. Looks like 5 posts above yours. The video poster shows the tubes he uses.
Hi, If you are still looking, I got my Permatex from Home Depot. There was a couple of option but I got the black Permatex that works with Oil. https://www.homedepot.com/p/Permatex-3-oz-Ultra-Black-Maximum-Oil-Resistance-RTV-Silicone-Gasket-Maker-82180/308852434
Follow the video and you will be fine. It takes about an hr. to do. All the stuff the DW gives about replacing o-rings is BS. I did it new and there has been no oil leaks since I put oil in the saw. Good luck.
Junk. Save the frustration and just dont buy it. Any other brand is better. I returned a number of these because of the mess they make in the trucks. Bought another brand. I’ve owned several chainsaws from electric to gas and none leak this bad. Terrible design.
Mine performed well for a few years of light use. Then the leak, plus flinging oil off the bar while sawing. The dealer sent it to a DeWalt “certified” service center. 60 days and $75 later I had a saw that worked fine for a couple minimal-use months. Then the flinging and leaking resumed.
I really wanted to keep these saws. We have a ton of dewalt tools and batteries. But ended up buying the Greenworks 80v saw since we have that brand of yard care stuff. But it is heavy.
I hope someday they make a new version that doesn’t leak all its oil out in 24 hours. The first one leaked inside the truck carpet, then I started putting it in a thick garbage bag. That got messy and gave up. Returned it.
Please note that the recommended fix to put an O-ring on the cap doesn't work. I tried that with many different sizes, but the leak always persisted because it is between the tank and the saw body. I also tried replacing the existing O-ring that is between the tank and the body and that didn't work either.
Wish I could have returned it but it was a gift. My solution was to get a used gas stihl ms250, lots more power and no leaks.
Sadly, it is a decent little saw, IF you fix the oil leak. As I posted earlier, tear the whole damn thing apart, put a little permatex on all the ports of the oil tank, and reassemble. The leaks happen because of the oil-tank manufacturing process - they seam the two halves together, and that seam interferes with the ports. Permatex or similar will fix it for good.
I also said before that it's sad that DeWalt doesn't do this during the manufacturing process - would take about 10 extra seconds. Instead, I had to take an hour to tear it all apart…
I am going to try to fix this thing as I have gifted it to my wife and she likes using it. My solution was to spend like $2500 bucks and give up on Dewalt and go Red instead, solved most of my Dewalt issues including DOA tools and terrible support when they die.
Robert, it's a pain in the butt, but if you like the saw, tear it apart and permatex all the ports on the oil tank. Someone posted a youtube video of the process. Takes about an hour, but worth it.
Dumb question: how do you loosen the 10-mm chain drive bolt? The drive just turns along with both ratchet and drill.
It's ‘left-hand’ threads - you should be able to hold the sprocket and break it loose with nut-driver drill. Here's a video that I found helpful. https://www.youtube.com/watch?v=DOcs38FmNJw&t=790s
No dice.
Pretty terrible design… very disappointed in dewalt for not doing anything to correct the issue. Did you guys do any quality testing before releasing this product? But thinking about it more, thay would cost money… which then the execs wouldn't get as big of bonuses.. I'll be exploring other brands for the rest of my tools.
What is sad is there own support tells you to put in an o-ring when there is already an o-ring that is why adding a second one does nothing. Second of all that is not even where it leaks from! I will say it again you don't need an o-ring on the cap because there is already an o-ring about an inch down into the neck. Everytime you put the cap on you are literally pushing it through that o-ring!
Pretty sure dewalt doesn’t look at these comments.
I had (2) and threw both of them in the garbage due to being tired of cleaning up the oil mess on my garage floor and the saws themselves. When I first noticed the problem, I took one of them into the Dewalt repair facility to get it fixed only to find out it leaked right after I used it. These should be discontinued as Dewalt doesn't care and are clearly selling a defective product which at some point, someone will sue and possibly do a class action which will cause this company a lot of cash and cause Donald Allan Jr to lose more hair!
Actually just based on this experience, I would NEVER buy DeWalt again. The problem is, I have already got a bunch of other stuff and batteries, which are pretty decent and too expensive to dump. But for those considering going in new / for the first time, suggest considering the RED brand (Milwaukee).
DeWalt, just hear what you are doing to your customer base.
