This is more likely to be a problem with lubrication than anything else. Check to be sure that the main housing is well lubricated. You should be adding pneumatic oil to the gun periodically with the air. It is possible that the o-rings have a leak as well. Remove the top cover and check for lubrication and the condition of the o-ring seals. Replacement o-ring kits are available for around $40.

Roofing coil nailer will not advance nails


The feeder piston should be very hard to retract by hand and should move back and forth as quickly as driver piston moves. With nails removed and side door open, activate gun on rubber surface (old coiled up air hose or water hose ) and make sure driver and feeder move quickly. If not check for debris within feed piston or air passage to feedpiston. The spring straddles the feeder with the slightly bent part of the spring arms contacting the upper surface of the feeder (little grooves cut into feeder). When installed correctly, the tip of the spring arms will be pointing upwards and the back part of the spring between the two loops will be contacting the feeder shaft. Good luck.

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

It will shoot first nail but won't feed the next nail


could be a few problems, the feed piston might be sluggish, the spring might be missing off the feed pawl, the collation of the nails or a bad coil of nails, the driver might not be retracting fully. Now for the way to check some of these. First look at the coil of nails and the adjustment on the magazine, the nails should pull freely off the coil. Next remove all the nails and using a block of wood "dry FIRE" the tool with the feed door open to check the movement of the feed piston, it should snap back and forth and if it doesn't that would probably be your problem, could be dirty/worn orings or debris in the air chamber. UNPLUG air hose and check for the finger spring that holds the feed pawl tight and check the pawls for wear and asphalt not allowing it to catch the nails. Lastly fire the tool and check the piston, did it retract fully allowing the next nail to advance? if not you would need to probably replace the o rings in this tool. Let me know if you need more assistance. And if I have helped you would you please vote accordingly, thanks

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

My N12 stops feeding after every 2 or 3 nail.


could be a few problems, are you using the right nails with the proper collation. is the magazine set correctly for the nail size, is the piston retracting fully to advance the next nail, and is the feed pawl spring broken and or is the feed pawl moving freely, to check the last one remove all nails and open the door that would guide the nails and fire the tool and look at the feed mechanism to make sure working properly, sometimes the bumper starts to disintegrate and pieces get stuck in the air hole controlling the feed. Let me know if you need more clarification or help

I have Bostitch RN45 coil nailer. It sometimes does not feed nails. When I open the magazine the driver blade has not retracted. Gun does not leak, o-rings in drive section look to be in good shape and...


Causes of piston not retracting are as follows. Cracked /worn bumper, if cracked air will leak between piston and bumper. Try test, remove nails and dry fire gun against rubber or soft wood; depress trigger push gun against wood/rubber and hold in this position. Piston should stay down and no air should leak past nose. Worn piston oring, piston should not slide down cylinder under its own weight. Loose or missing check seal, remove cylinder and look for black rubber band around series of holes. Band should be in place and fit snuggly. Good luck

I have a Bostitch BT200 that is dry firing. It seems that the "hammer" is not retracting after it fires a nail. I have to push it back manually and even then it seems to dry fire a few times before a nail...


The check seal is what causes the piston to retract. Remove cylinder and examine check seal. It is a small band that covers a series of holes and should fit snuggly around cylinder. Other factors that have effect on piston retraction are, split/cracked cylinder, bent driver and lack of lubrication. This gun is tricky to rebuild. Make shure that all the parts in the head are placed correctly. The kit does contain all the parts that you need. Good luck

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.

Nails dont always feed 1 out of 2


could be feed pawl problems e.g. broken spring, restricted movement or the piston is not retracting fully, either way I would probably try and rebuild (new o rings, thorough cleaning) this tool. You can buy a replacement o ring kit from Nailgundepot.com you will need to give them your model number for this kit. Let me know if you need more help.

Paslode im350 piston will not return


It sounds as if the piston o ring is worn. Does the piston drop if you just give it a slight bump with no nails in the magazine, if so that is the problem and would need replaced. Let me know otherwise and I will dig deeper
