Either the blades are incorrectly installed causing the head to jam or the safety cover is not installed properly - there is a safety mechanism that locks the cutter head when the cover is removed.

Typical cause is low voltage - but can also be a bent driver or something jammed in the nail track. Is this a finish nailer or framing nailer?

That symptom usually indicates a low voltage issue - not sure how the adapter may affect this, I've never run them with a 20v battery. Try it with a standard 18v and see if you have the same issue - please comment back with the results, I'm curious.

From your description it sounds like the bearings on the armature seizing up . Mainly the bearing on the bottom towards the pad. I see it a lot . It'll seem ok when turned on but under a load it can stop , slow down , smoke ....I'd start by checking the bearings. If it was the cord power would cut in and out completely. It doesn't have a variable speed switch or any speed sensors on that model. .if you have any questions feel free to ask and give as much detail as possible plz.

reading the user manual reveals that it requires oil before using and regular oiling during use that is simply attained by disconnecting the air line and putting a few drops of machine oil in the connection and reconnecting the air back up that oil then lubricates the seals and piston of the machine do that and it most likely will work again

find out what thread direction the screws are before going brutal---an impact driver may have to be use to remove screws---don't know if they used lock tight on them or not from factory---impact driver is a tool that you insert in to the screw then rap the end of the driver with a mallet/hammer---this action keeps the screw bit buried in the screw and twists at the same time after being hit----this will work only if there's no lock nuts opposite the screw (other end).----GL

Trigger may be stuck try a little singer oil or sewing machine oil only a few drops should do it... trigger switch may not be working properly either
