Really hope this will save time for someone else having similar problem. Once you have found the wedged nail inside your nail gun, try to pull it out. Lesson #2: stick to original parts when possible and not something fishy from ebay Lessons learned: never try to fix something which is not broken. Ironically this part was the only one missing at DeWalt dealership, so I left the ebay one in (it was still new so why not lol!) when replacing the o-rings the second time.Īfter I put in the original o-ring back where it was, the nailer is working as new. Nail Capacity 110 Built-In Light Yes Features Micro Nose, Tool-Free Jam. Hence the air found its way out through the exhaust instead of moving the piston. These cordless nailers are made by DEWALT and are powered by a compatible 20V. Apparently the new o-ring caused the cylinder sease and not allow the air in when trigger is depressed. Tool-free jam release mechanism for easy nail removal Rear exhaust to keep contaminates away from work Drives 18 gauge nails from 5/8 in. I though the original just extended and worn out, but I was wrong. So when I installed the ebay O-ring kit I did not pay attention that the oring which seals the cylinder to the bulkhead (the black plastic piece between the cylinder and the nailer body) is somewhat beefier and thicker than the original. With its brushless motor powered by a DEWALT 20V MAX Lithium-Ion battery the DCN650 is ready to go to work. I spent hours looking at all nailer parts while assembling and disassembling it until I found this. The DEWALT DCN650 15 Gauge Angled Finish Nailer drives 15 Gauge angled finish nails from 1-1/4-inch to 2-1/2-inch which makes DEWALT finish nailer ideal for fastening crown molding, casing, baseboards, and hardwood floor installation.

Here is what was the problem, hopefully it will be of use for someone. On the other hand, if you are a new user of Dewalt, definitely you should buy the DCN692M1 framing nailer. Because this nail gun can compatible with all DeWalt 20V MAX batteries. Sure thing I do disconnect the air house while not using the nailer, sorry if I forgot to mention that. If you already have a Dewalt battery and charger, you can buy a DCN692B framing nailer.
