Probably not enough air through the regulator to the gun. Is the tank rated enough for the gun? Is the regulator set high enough to allow the air into the gun's air feed line? Are the feed line or any of the connectors or the air passage inside the gun blocked? Any or all of these could be the problem.
Hope that helps. Best of luck! :-D

My 601 won't shoot any spikes it just leaves a 1/4 '' indent were nail should be?


If you're getting an indent in the wood from the driver, the gun is working properly. If the gun isn't driving fasteners/nails it's because the nail isn't under the driver when it's activated. Several things could cause this: Having the wrong angle nails in your gun. There is something in the feed path of the nails preventing them from feeding fully into the nose piece. The feed shoe is jambed or feed shoe spring is broken.

The gun won't work right


As a safety precaution, nailers have incorporated a safety foot that will prevent the gun from firing unless you push down hard. Some guns also have a system where the gun will not fire at all if there are no nails in the gun. To dry fire this type of gun you must pull back the pusher or open the side door. If nails do not feed properly, check for wrong nails, bent rails or weak pusher spring. If all is good with rails and pusher, suspect that the driver/piston is not at top of cylinder and lower part of driver blade is preventing nails from advancing. Remove airline and push the driver to top and retest. If driver is slipping down the cylinder under its own weight, replace oring. Good luck

Nails fail to feed


Without knowing your model number here are some things to check, in order of difficulty:
1. First make sure you're using the proper nails for your gun. If your gun isn't specifically listed on the box of nails as compatable make sure they are seating in your gun properly. Some brands of angled nails are a couple degrees off from others and won't work in competetor's guns.
2. Check the entire feed path of the nails in the magazine all the way up to where the driver catches the next nail. Sometimes dirt builds up in the track or there could be a peice of nail stuck in there preventing the nails from getting under the driver. Also the spring on the feed shoe should have strong pressure on the shoe all the way up to the head and the shoe has to ride freely in the magazine.
3. If the gun is making holes in the wood the driver isn't broke but it must be straight and true and the tip square. If not it will miss or slip off the nail before driving it. The only way to check the driver is to remove the head on the gun and take the driver out. The piston & driver should travel from the top to the bottom of the cylinder without binding anywhere. Correct any problems you find or replace any damaged parts and your gun should work.

I'm trying to figure out why my PC FN250A won't fire nails. I don't see one jammed. What else can I try?


If the driver is not returning to top of cylinder, the nails will not feed into position. Remove nails from the gun and Insert thin tool into nose to verify that the driver is all the way up. If the driver is already at the top of the cylinder, then nails are not feeding correctly (check for debris in rails or for proper nails). If the driver was not all the way up, check for bent driver blade, loose or too tight piston ring or restriction in the headvalve (upper bumper cracked). Good luck

I have an Hitachi NV83A2 it won't feed nails anymore. Everything else seems to work properly. After about 20 or so hits on the trigger it will feed the odd nail? I am puzzled as to which course of...


could be a couple areas to look at. First lok at the coil of nails and possibly try another one. Check the adjustment of the coil for proper feeding. If all ok there, remove the coil and get a block of wood and safety glasses. Open the door and "TAP" the nose on the block of wood and look at the driver does it fall down into the lower area without the trigger, if so the piston o ring is worn not allowing it to fully retract and advance the next nail. If not apply air and DRY fire the nailer while looking at the feed piston/pawl, it should snap back and forth, if not there is either a worn oring or debris in the air passage. Also the pawl should have resistance if you push outwards on it. Sounds like a lot but only takes a couple minutes to see where issue is. Let me know if I can help

Remove nails and use thin tool to push driver all the way up to top of cylinder. If the gun fires one nail then skips, the driver is not returning to top of cylinder. If no nails fire, then nails are not feeding into proper position. Driver must return to top to allow nails to feed into position. Most common problems are bent driver, worn piston oring and bad batch of nails(head too large). 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

Do I need to lubricate my Bostitch F21PL nailer from time to time? The reason I asked is, I got this new nailer. Installed Galvanized 2.5 inches nails from Bostitch and with the metal connector installed....


This is a fantastic nailer, very powerfull. Information about your nailer can be found below.

http://www.bostitch.com/default.asp?CATEGORY=BOS_FRAM_NAILER&TYPE=PRODUCT&PARTNUMBER=F21PL&SDesc=21%26%23176%3B+Industrial+Framing+Nailer+System

You should not need to lube the rails for the nails to feed. Your nailer uses plastic collated nails and should travel very easily inside the rails. I would remove all the nails and check for broken pieces of plastic from nail strips. Feeder should feel snug within rails and not wobble and spring should pull tight. When you install the nails do not release feeder against the nails with force as this could break the plastic strips and cause jam. Nail not feeding is usually caused by wrong nails, weak pusher spring or pusher guides broken /missing. Simple test for proper nails.
Place a strip of nails on the outside of the rails aligned with the edge of the rails and see if the first nail is perfectly aligned with the path of the driver. If the head of the first nail is angled back slightly from the path of the driver, the nails will not feed properly. Good luck.

Feed issues


This is usually caused by a dirty nailer. If you don't have the instructions on how to clean it you can download them from Porter Cable.
