Why is my chainsaw leaking oil?

    Emptying the oil tank after using is not very practical - for one thing, the fill hole is not really designed for dumping the oil out. 
    2) A primary reason I bought this saw was for convenience - I don't have to spend time with messing with gas/oil mixture, etc. And it is quick and easy to use for small, occasional cutting jobs.  But if I have to drain the bar oil after using and then refill it prior to each use, so much for convenience. 
    I am generally a big fan of Dewalt tools - and I've loved the chainsaw in general, until I discovered it leaking oil all over. So, needless to say, I am disappointed.

    I found the reason that mine is leaking oil and it has nothing to do with the tank. I took mine apart after being fed up with the deluge of oil coming from mine as well. On mine, the o-ring on the end of the emitter is too small to create a tight fit into the recess in the housing. Thus, the oil leaks into the housing instead of being fully emitted onto the blade, and then leaks out slowly over time. I'm going to try and retrofit a larger o ring or sleeve it with a piece of tubing for a nice tight fit. That should cure the delayed leak, as the rest of the system is well sealed and doesn't leak.

    Steve Barnett and James Crockett are pointing out a major problem that all chainsaw users face, and should be addressed when new saws are being designed.

    But an incorrect o-ring size can be corrected without a design change. Dewalt should check whether this is a one-time manufacturing mistake, or common, and if common immediately correct.

    I agree completely with Steve Barnett about the convenience of a battery powered chainsaw.  Having to drain the bar oil after each use is not practical and very messy.  I like the saw for its intended use but I really do not like the leaky bar oil issue.

    I also agree with James Crockett that DeWalt should fix the problem.  I have a Makita battery powered chainsaw that works well and does not leak bar oil.

    Additionally - DeWalt should make a chainsaw bag for each of their battery powered chainsaws.

    I absolutely agree with the above.  Recently purchased both the 20V chain saw and the pole saw.  Both leak miserably.  Not convenient or practical to drain oil - that is not an option. I sent the chain saw back, thinking the pole saw was only leaking around the filler-cap; nope -it's leaking from below also.  First DeWalt tools I've been disappointed in.....

    That is a cop out response for a chainsaw, obviously there is a oring / design SNAFU.  Ironic from a generally great tool maker.. emptying oil or release what ever trapped pressure ( when lol, the weekly season change, here in TX), get serious...

    I agree with all of the previous comments.  Dewalt obviously has a design flaw that they need to address.   It's that simple.  Problem is that they need to receive sufficient negative feedback or chainsaw returns for them to make it profitable to make a design change.  As long as we keep buying their tool with the leaking chain oil reservoir, nothing will be done....or it will take another few years for them to fix it in their next, newest design (...MAYBE)...   This is a frustrating, messy design problem for customers to deal with that tarnishes the otherwise very good Dewalt product name.
