Re: Airy ATK 0250S nailer Can you send a trigger kit to fit this tool

You just need an O-ring kit. It is letting air past the trigger and valve.

Sounds like the head valve. Remove the head cap take out the head valve, clean, re-fit and give it a few drops of air line oil. Then give it a try. Good luck.

Usually, rebuild kit has a replacement trigger valve. However if you are attempting to rebuild the valve, pay close attention to the fit of the orings where they make contact. The valve has four parts. End cap, lower body, inner spool and trigger pin. The critical orings are on the pin and spool. Replace all the orings, making sure that parts fit snuggly. The trigger pin orings should fit snug against end cap and inner spool. The inner spool should fit snuggly into end cap and lower half of the valve. Good luck with your repair.

FOLLOW closely, take a small pin punch and knock out the pins holding the trigger in place and then the 2 pins for the valve, one is probably longer. Next get a shop rag or good glove and holding back the collar that locks the air fitting to the tool push the chuck on the air inlet while holding your gloved hand or rag under the valve assembly. It will POP out make sure not to lock the chuck to the tool. Loghtly grease the o rings and make sure that you align the slots on the new one with the holes where the pins go. reassemble in reverse order.

Sounds like you need a repair kit or take to a tool company that installs the kit.

ereplacementparts.com. see if they have a schematic for this gun. Good luck sound like a head cap seal.

You should be able to find a local Dewalt/Black and Decker service/repair shop and they will be able to sell you all the parts you need, I would recommend getting a full upper rebuild kit and replacing everything, while you have it open already

Airy no longer has a home base in the USA. E-bey might be your best option
