Brad Nailer Under Water

If it were mine, I’d take it apart as much as possible… then clean and spray down everything in sight with some WD-40 to displace any remaining moisture. Then a good long session running extra pneumatic oil through it just for good measure. What you did was probably sufficient – I just like taking things apart :)

Cheers,
Brad

Mind you, I have never opened the top of one of these, but I just did…should i see any moisture of any kind in that “chamber?”

They aren’t too complicated to disassemble. Just to be safe it wouldn’t be a bad idea to have a schematic handy if reassembly gets tricky. Wipe down everything with a dry rag or towel and apply a little air tool oil to everything before putting it back together. I’d cycle it several times before doing any work that could be damaged or stained by a little oil mist in the exhaust. Beyond that, just using it will help to get any water out that you can’t readily get to.

As mentioned, they aren’t complicated but the metal
parts inside are not made of stainless steel so rust
is likely if you leave it wet for too long.

They are designed to handle condensed water in
the air lines. It happens. Name brand nailers
are pretty robust in my experience.

I would fill it with WD40 and see if it will shooting.
After shooting about 50 nails I would put quite a bit of oil in it and keep using it every day for a few days.

But to do it right you’ll have to take it apart and dowse everything in WD40.

They really aren’t that complicated. I’ve fixed a couple and was surprised how simple they are.
Have a parts diagram handy! Take pics when you break it open.

Yup WD-40. This is what the stuff is actually meant for.

When disassembling anything, I always use my phone to take pics so I can put it back together. Saved my bacon more than once.

The greatest use for a phone is taking pics as you take something apart. Can not take enough pictures.
