SOURCE: CRAFTSMAN NAILER

Generally, if your nailer is not leaking air, the orings are probably ok. Remove the head and check for stuck headvalve or stuck driver/piston. Make sure that you can press the headvalve into the head with your thumb and that it returns. If your driver/piston is down when you pull the head, remove the cylinder and check for damage to it or the bumper. Some cylinders have an oring or strip of rubber about med section which acts as a check valve causing the piston to return to top. Check for bent driver or broken tip causing driver to jamb. Use silicone lube to assemble. Enjoy

you probably have a trigger valve that is green. if so then it will have to be replaced, the valve runs about $ 20 but you can put it in your self.

SOURCE: Senco SN4 nailer not feeding

ther isn't a spring, it works on air to pull the driver back up. Have you tried oiling the tool as recommended (about 6 drops a day) If not then you have a problem with either o rings that are dried out or worn so they cannot keep the suction required for the tool to operate properly. Might also be a bent driver (doubtful). Go to Senco.com and type in your model number and they list rebuild kits for this tool. If you need more assistance let me know and if I have helped with your request would you please rate this accordingly.

SOURCE: Porter cable finish nailer won't work. Not jammed

On the front nosepiece, unlatch the nose cover and see if you can push or pull on the driver pin. If you can push it into the housing all the way and feel the resistance from the driver piston it is not your driver. You may find that you can pull the driver but it will not go into the housing all the way. In this case you have a broken driver and will need to replace it. Note the driver pin should not lean sideways at all when you are pushing it into the housing. It sounds to me like a driver problem. Remove the four backhead screws and take the head off, be carefull not to damage the gasket. Remove the press ring (looks like a round cage) Then you can remove the cylinder. If it is the problem I think it is you will see the driver piston cocked sideways in the cylinder and a broken driver pin sitting at the bottem of the housing. You will have to replace the driver and the cylinder. along with any seals in this assembly. If you have any questions please post and I will try to answer.

SOURCE: air blows thru the trigger on both my finish nailer and staple gu

there is an o ring in the trigger valve referred to as a Purple o ring that is probably split. If you can find a air tool center that has them you will save a lot of money versus replacing the trigger valve. Let me know what you are going to do and I will help you with the removal of the valve.

F28WW-fire gun. piston doesn't retract back, trigger is good gun is clean & oiled what could be the problem. nailer year old


Check band # 175520 (black rubber band around the outside of the cylinder) is what causes the piston to retract. If the check band is in place, then problem could be caused by cracked lower bumper, worn piston oring or cylinder seal on the headvalve. IF the cylinder seal is bad, air will leak between seal and the top of the cylinder and could push piston down cylinder. If piston oring is too loose, the piston will not stay at the top of the cylinder. If you point the nose of the gun up then down again and the driver moves within the cylinder, replace the oring. Good luck

I have a porter cable roofing nailer model # RN175 that does not advance the nails everytime what causes this?


Some causes, in order of probability:
Roofing nailers get a lot of tar build up on them, especially around the nose safety and nail feed pawl area. Cleaning off this buildup will usually take care of most problems with roofing nailers.
On the side of the gun away from the side you load the nails on there is a small cylinder with a piston inside that attaches to the feeder pawl. If air isn't getting to the piston or the piston's o-ring or spring is damaged, it won't cycle properly to advance the nails.
If the driver doesn't retract fully, the next nail won't be able to advance properly for the next shot. This can be caused by o-rings in the head that are worn or out of their proper place.

Wont shoot nail every time pin wont return all the way up


Some reasons the driver/piston assembly won't retract fully:
- damage to the o-ring (LB1003) around the piston
- cylinder (BA0165) is scored badly
- driver (EA0167) is bent, twisted or warped
- o-ring (LB1023) around bottom of cylinder (in groves & covering small holes) is stretched out or out of place.
- Seal (BC0492) at bottom of cylinder & under bumper is damaged or gone

N12 nailer doesn't retract completly,changed all orings,trigger valve,cylinder/piston looks good and lubricated, whats wrong?


For nailer to retract properly the lower bumper should not be missing any pieces or cracked. The upper bumper should be pliable and complete. Pull the cylinder and check for a groove cut into cylinder with a series of holes. This groove should have a snug fitting oring. It should not take much force to move the piston within cylinder. If all seems good, re-assemble using silicone paste lube available at Lowes or swimming pool supply. Easy test. With air connected and nails removed, dry fire gun against coiled rubber hose. Keep holding the trigger and keep the gun against hose. The piston should stay down and no air should leak from gun while holding in this position. Lift up gun and the piston should retract. If air leaks from bottom while holding in this manner, lower bumper is not sealing, if air leaks from top, then upper bumper is allowing air to leak from head valve. Good luck

I have a Senco pro 35 18 gauge finish nailer been working fine now I just get air when I pull the trigger


could be a jammed nail in the nose/magazine area or a driver problem. is the driver fully retracted or stuck partially down in the nose. UNPLUG the air before checking. If the driver is partially down I would think a jam and fully retracted you might have an issue with the piston/driver assembly.

first make sure you are using the right guage nails. then I would look at the condition of the driver to make sure not bent, also look for a broken nail in the magazine area which will also cause this, lastly does the piston/driver "fall" in the cylinder?? there should be some resistance against the o ring, if not then it could also cause your described problem,

Hammer doesn't retract


Assuming there is no air leaking from the gun, the check seal (part #175520) causes piston to retract. It is a band that fits around the cylinder and covers vent holes in cylinder. You can use orings in place of band (or be creative). Other reasons for piston not returning to top include bent driver, worn piston oring, or cylinder/ oring lacking oil. Good luck

Hello My PC 18ga brad nailer its piston wont retr...


Check the regulator gauge on your air compressor to make sure you have enough air pressure going to your nailer. After replacing my nailer because the driver wouldn't retract, I discovered, when the replacement nailer had the same problem, that I had somehow turned the regulator and decreased the pressure. Now I have two fully operational nailers.

Piston not retracting


First does it retract after unplugging the air and if so I would look at the trigger valve assembly for a sticking plunger. If not then I would look at the firing valve in the cap. Let me know if I can help further.

Senco finish nailer, drive pin doesn't retract up to take another nail...


Senco nailers are very reliable however could suffer from several issues that would cause your problem. Here are a few things to check that may solve your problem. Bent driver, worn parts, broken check valve. Main problem with all finish nailers is bent driver blade. Easy to check, remove and examine. The driver should travel length of cylinder without jaming. Driver oring/plastic ring should fit snug into cylinder. Remove cylinder and check the oring neer the bottom of the cylinder. This is a check valve. There are small holes that should be cleaned. If oring is loose or broken just use any oring that fits snuggly. Next, check that lower bumper is not chipped or cracked and that washer under bumper is not too worn or missing. Replace parts as necessary. (www.toolpartsdirect.com)
