Porter Cable nailer problem

[rile]

My son has a Porter Cable brad nailer. He called me this afternoon to ask about a problem he's having. He says that air is leaking out of the top of it. I've not seen it but he says it is leaking out of some type of screen. I'm sorry I can't give any more details than that since I've never seen it. Any ideas?

It might need nothing more than a drop or two of oil -- try that first.

Yup.

Oil.

I put 1-2 drops of oil in my BN everyday of use. Bigger guns get 3-4 drops. These things need oil but it is not a good idea to flood it and forget it.

Thanks for the help. Is there a oil fitting?

Lay the gun down (prop it up) so that it is sitting on the front of the gun with the end of the magazine and the air coupling pointing straight up. If the gun is dry and that is the leak source, put 10 - 12 drops of oil in the air coupling and let it sit propped up for an hour or so. The oil has to work its way to the front of the gun, then it will get drawn into the piston and onto the "O" rings.

You didn't say how old it was, or how much it has been used, or if it received any routine maintenance. You may have blown a cylinder ring or even have a leaky head gasket.

If it is just a dry ring, you are lucky. If it is the oil required gun, then you should put a couple of drops in the gun at the start of each session, and if you are using it a lot, put that much in again after using it for a few hours. When trimming, I put oil in first thing in the morning, and again after lunch.

Good advice.

I got into the habit of a drop (or two) each time I load a new strip. I also put in a few drops if the gun has been sitting for a few days or more. I have a 20+ year old Paslode stapler and 16ga finish nailer which have been used a LOT in production etc...but neither has ever seen a service dept.
