Stuart - this sounds like an air problem - you should perform the following test. With the air nailer close to the compressor you must monitor the airpressure after the gun fires. it sounds like the air is not gettting through diapram fast enough or there is a blockage in line. Blockage in line is not suspected for the following reason . It sounds like the air hose is holding enough air to fire 2-4 nails and then you must wait for the line to fill up again and then it fires ok. The pressure regulator out to the line controls this and they do fail. try this test and report back to me - I know I can solve this for you as I have extensive background in compressor and the like.

Where does the air leak out from? If it leaks from the trigger DeWalt makes a trigger valve assembly part # 641006-00 list 8.89 BUT if it leaks from other areas we have to look into it deeper. If it is just the trigger valve let me know and I will give you instructions how to remove and install the new one.

I have worked on many sfn1 with the problem that you describe. Here are a few things to check. Driver/piston too tight or too loose in cylinder or bent. It should be relatively easy to move the driver piston up/down the cylinder. Usually it should hold it's own weight and not drop down the cylinder. There is a washer that should be at the bottom of the gun under the bumper (washer part# bf0070). This washer must not be worn to the point that too much air will leak past or missing. Finally there is an oring that controlls return of piston (part # lb0077). Pull out the cylinder and find it located on the outer part of the cylinder close to bottom. Clean the port holes under the oring and make sure that the oring fits snuggly. Do not use oil in this gun. Oil will swell the rubber parts. I use silicone lube available form Lowes in the plumbing department. The grease is used to lube faucet orings. Good luck with your repair and email if you have questions.

Any time these guns become intermittent or stop firing but the fan still runs, the first the to check is the expiration date on the gas cartridges. The do expire and this will make the gun work inconsistently or not at all.
