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.

This oil tank doesn’t appear to be sealed well enough. Dewalt company need to fix the poor oil tank design and give the folks who purchased it the fix too.
How do you remove the oil cap in order to install o-ring?
the oil leak is not just from the filler cap. It also leaks from all the orifices - vent, output tube,etc. Can't understand why Dewalt has not at least put a gasket sealer on all these openings - this is not a new problem. It would take them a matter of seconds during assembly to do this. For the home owner it's much more involved - tearing the entire maching apart, apply sealer, then reassemble the machine.
I just got one of these. Love it except whenever I set it down there's a little puddle of oil left behind. I've seen videos on how to repair this but if I tried those it would not get put back together proprerly. DeWalt should foot the bill for a fix.
The recommendation to remove the oil from the chainsaw every time you use it is an insult and should be removed. Anyone using a chainsaw frequently is just not going to do that. I don't do it to my Stihl, and I don't have any leaks. DeWalt needs to fix the leak problem. Reluctantly, I ordered another 20V Dewalt chainsaw (most of my other power tools use the same battery). Only this time, right out of the box, I took the entire saw apart. As indicated on a very good you-tube video, the seams in the oil tank are prime spots for leaking. I put gasket sealer around the vent, the output tube, and the fill assembly. Reassembled the saw and no leaks. Instead of me taking an hour to do this, Dewalt could have this done during assembly in about 10 seconds. I agree with Homer, Dewalt should foot the bill for this 'repair'.
How does Dewalt not know the leak is not from the oil cap? And there is an o-ring its just not on the cap its in the neck! A blowup of Dewalts own parts diagram shows the o-ring as #67 part number DWB-90618339. But somehow they don't know there own part excists. Now everyone running around putting in a second 0-ring on the oil cap wondering why there chainsaw still leaks! Store it with the oil cap facing down yes down because the oil leaks from the opposite side not from the o-ring thats already there! Stored mine on its side oil cap to the floor since I bought not a drop!
This issue is actually a huge safety problem. My saw leaked like a sieve form the first hour of use! This past weekend I was limbing about a dozen fallen trees that took about 6 hours all in. By the time I was finished my leather work gloves were saturated with bar oil so much so that the saw was moving all over in my grip or lack there of and even climbing in and out of my tractor was difficult and dangerous as I could not properly hold on. The tool box mounted to my tractor was coated in bar oil and by the end of my work session was covered in oil soaked wood chips. It took me 20 minutes to clean it and there was still a thick coating of oil in the bottom. This was my first Dewalt purchase and you can bet it will also be my last purchase from them.
I agree with earlier comments that the problem should be corrected by Dewalt since the oiler system has a design flaw that negatively affects the normal use of the saw. My saw leaks from the bottom area near the blade, not from the oil cap. Has leaked since I first got it, a real pain and messy. I agree that after purchasing numerous dewalt power tools, this may be my last if they don't stand behind their tools and take care of their problem.
Rod,
I agree with you 100%. Dewalt could remedy the problem in about 5 seconds during the manufacturing process with a little bit of permatex. (see my post from 2 months ago). The seam where the two halves of the oil tank are joined prevent the ports from sealing and that is where all the oil comes from . I completely disassembled a brand new saw, permatexed all 3 openings in the tank (filler, vent, and output), and have had no problems. Sad it took me an hour when Dewalt could have done it in 5 seconds.....
Thanks, I'll likely be trying that.
awful product design, I wish I could get a refund. Terrible customer service.
yes, very disappointed. a nice tool with a fault that makes it unusable. looks like ill be tearing it down. this problem needs to be rectified immediately.
Never buy any thing dewalt again
It’s surprising that Dewalt has been silent on this subject since putting out the BS about the cap and emptying the oil. Dewalt where are you?
