Howdy Fella’s.
After a day of festivities it was time to get back to work on the Christmas present I was building.
I went t to use my Porter Cable BN 200 brad nailer and I was stopped dead in my tracks.
The plunger will come forward and shoot one brad but will not retract back into the gun and load the next brad.
I can manually push the plunger back into the gun but there is quite a bit of resistance.
I have disassembled the gun, as far as I feel comfortable, and I cant seem to find the reason for the misfire.
Everything was nice and oily. The small gasket on the plunger seem to be in good condition.

Any ideas?

Many thanks,

Bill

Check the bore of the plunger mechanism for crud, corrosion, etc.
What air pressure are ya using?
Is the driver free of burrs?

The plunger seems fairly smooth.
I have tried 70 psi all the way up to 120.
Same results.
It’s the recoil action that is failing.
