I have the CN350 - not sure how it and the 350B differ.
There are several possibilities that I've experienced.
Nails other than Duofast. Causes a jam that does not allow the driver to return.
Not enough oil.
Not enough air.
Worn O rings.

I have a 2003 dodge durango 4.7 and it is overheating which i already r&r the thermostat. fixed the problem a lil but not 100%. also check engine light turned on for second time both same code P0308...


yes... overheating can cause issues in your piston/cylinder head. if your cylinder head is made from aluminum and not metal, overheating can cause cracks and bends in your cylinder head. if this cracks occur inside the combustion chamber, then proper compression cannot be attained. you need to rebore then resleeve your combustion chamber and change the pistons to fix this issue. this will also require resurfacing of cylinder head to ensure that it does not create leaks against crankcase.

I have got a second hand Duo-Fast CN350B Nail Gun. It is new to me, and I dont have a operating manual for it. I have heard they accept multipule guage nails, is this true? Also can the nail driving depth...


They use 20 degree, full round head, plastic coalated nails. You can shoot nails ranging in guage from .099 to .131 and I believe from 2 3/8" to 3 1/4" length. It is a heavy but well built and powerful tool. It's not made anymore because Duo-Fast has long been sold to ITW which also owns Paslode. The owner of Duo-Fast (third generation, family owned) got very ill with cancer and ended up passing away quite a few years back. I worked as a sales rep for Duo-Fast in the early 1990s. I can not find an owners manual link for you. They don't have an adjustable depth but they do have a flush adapter. Here is a link to a parts diagram. The flush adapter is part number CN-133 and is held on with a screw.

I have a duo-fast n350 ant it sets the nail to deep . any adjustment


Three methods to adjust how deep nail will set. On nose of gun is fine adjustment, move contact claw by backing off screw and moving up/down. Replacing the lower bumper with new part will prevent driver from driving too deep into work (new bumper is more firm and probably thicker). Finally, adjust piston on driver blade by turning then re-apply lock tite (adjust piston head closer to work). Good luck

I have a duo fast CN 350 nailer and it works ok but it don't seem to let the driver blade to come up high enough to get on nail head


You will need to pull the top off to get to it to check it out, If the drive pin is bolted on, make sure the bolt didn't loosen up, most are one piece, welded on, If you don't find anything in there preventing it from coming up, I would grind off the tip, nice and square and flat, then put it back together. I have a feeling you will find a piece of white plastic holding the piston down, part of the head there, It will need to be replaced. Check it out, hope this helps.

My Porter Cable FN250A only shoots nails sporadically. When I lift up the nose piece, it appears that the "hammer" is not fully retracting.


Piston not retracting is caused by several issues. Bent or broken driver, worn piston oring or loose or broken check seal. Remove head and examine driver for bent or broken, adjust as needed. Check that piston oring fits snug, piston should not drop down cylinder under its own weight. Pull cylinder from body and check that black band (check seal) is in place around holes in cylinder. Good luck

Paslode nail guns won't shoot


piston is probably jammed

This happens sometimes try holding it up against a board with the trigger depressed and then inset the battery.

The goal is to try to force the firing sequence to get the piston back to the right position with corded units this is simply done by attaching the air hose with the trigger pulled this causes air to rush into the gun chamber pushing the piston back and firing a nail out.

The cause of this is a misfire or jammed nail that stopped the piston in the wrong location so air will not build in the chamber correctly.

Hope that helps
