Porter Air Tools & Compressors - Recent Questions, Troubleshooting & Support

The trigger is broken.You should buy a new one.

The nailer is made in Taiwan. Taiwan makes many hand tools. Their success lies in use of industrial clusters. I cannot narrow the producers there. It has no associaton with Cable and Porter, headqueartered in Tennessee. The price of a replacement for this widely varies. Here are a couple of links that may or may not be of service to you in terms of parts: https://mastertoolrepair.com/air-compressor-parts-c-25.html?osCsid=0f2shgpimf2pi0vit26tj7jphn https://www.amazon.com/Central-Pneumatic-Tool-Parts/s?k=Central+Pneumatic+Tool+Parts https://www.manualslib.com/manual/959009/Harbor-Freight-Tools-Central-Pneumatic.html?page=18

check and lube the triggers--and ram rods --

Two part answer - "jumps over the nails" does your model have "select fire"? If yes, check the switch and make sure there is no play or that it's not gunked up or anything like that. Some contact cleaner should help. Make sure it's on the right option for the way you are using the gun... "bump fire" is cool and fast, but risky. If no, check to make sure that your available PSI is what your model needs. "use it over your head and nails fall out" are you using the right size/type for the gun you are using? Clipped? Round? Length may play a factor as well. ** without the model number, I'm answering in broad strokes because I can't give you a specific answer, sorry.

what you are doing is not right take it to an air tool repair shop and have it fixed proeprly

It sounds like you have a bad seal or O-ring. without takeing it apart and looking at it myself i cant tell you witch one is bad.if take it apart look the orings and seals over reall well and se if you can find any distorted places on them and then you can find a breakdown of the nailer and buy the seals or O-rings on this site.http://www.ereplacementparts.com/

Hi Charles & Floyd: Just a couple of thoughts that may assist. First. This is an air tool so it is DANGEROUS! Treat it like a LOADED GUN. Here's what I would do: - Disconnect from air supply - point away from anything I don't want to hurt, and squeeze trigger. Press safety against block of wood and squeeze trigger. - Now that I know it is safe, I would remove the nails from the magazine and check that none is stuck in breech mechanism. - Check that feed spring/latch has released. Sometimes if loaded too full it can catch. - Load some nails, check that they are the correct fit, and are sliding in the magazine. - check air supply pressure. Should be between 80 and 100 psi. - reconnect air supply and try again. - If it does not fire it may be that the piston is not fully retracting. Since it is new, I would be returning it to the store where it was purchased. Hope this helps.

the piston is probably dry and jammed or the hammer is stuck in a position that is not allowing air into the chamber have it inspected by a tool repair shop and make sure that there is an oiler in the air line

pound out the trigger rocker switch and see if its that. press the trigger valve button without the trigger in place. could be your trip is not engaging the trigger far enough to make sufficient pressure to push the trigger down .

Is it on warranty? Return it. Past warranty? Ask at shop where you bought it if they have some repair service, ask for diagnosis and evalate is worth to repair or by a new one.

have you oiled this tool .and if so are you sure this tool uses oil.because some nailers do not use oil and if you oil it they will most likely stop working .if this is the case you will need to take it apart and clean it with a mild cleaner .we use a water base cleaner to keep it from damaging the orings. if this doesnot fix it you will probbly need to put a Oring kit in it.you shoul be able to get this a ereplacement.com .i hope this helps you out.

It sounds like the nail gun might need a lower end seal/repair kit.

suspect that the carburettor will be gummed up or corroded from the fuel drying out over the non use period.
