The Bostitch rn46 is a very good nailer however suffers from the problem that you are experiencing. Easy to fix. Remove the nails and connect to air pressure (100psi). With side door open and trigger depressed, cycle the gun against old coiled rubber hose or soft wood. As you cycle the gun, check that the feeder is moving back and forward with speed and the driver is moving down then up again. If the feeder seems to move in slow motion back and forth the air passage that feeds air to the feed piston is restricted or oring/spring to feed piston is worn. If the feeder moves very fast then suspect worn driver oring. To check driver oring, remove nails and air supply and leave open side door. Point nose of gun up then down to see if the driver seems loose and is moving up and down the cylinder. When the driver oring is good, the driver will stay at the top of the cylinder. If the driver oring seems ok and the feeder moves very fast then suspect feeder spring weak or missing. I usually find that debris from lower bumper and driver piston oring shavings have entered/clogged the air passage to feed piston. Replace parts as needed. Good luck.

SOURCE: Leak inside Bostitch N80 Nailer, won't drive nails

If the unit is leaking it most likley need a rebuild kit. Go to a Bostitch service center and ask for an ORK-11 kit. That is all the o-rings needed to do an over haul. Or just have them do it.

SOURCE: How do you safely remove jammed nail gun?

Not sure exactly what Bostitch framer model you have, but if it is powered by compressed air, as long as you remove the air hose from the nail gun, there should be no risk of the nail gun firing while you remove the jammed nail. There should be a way to access the driver area from the top of the nail gun, even via a latch or a couple screws. Remove the top part of the driver area and that should give you access to the jammed nail, which you can remove. Use long nose pliers or something similar if the nails are really stuck.

SOURCE: will bosch nail guns operate with Paslode brand nails?

The F28WW takes 28Deg nails that are collated with wire, so your nails won't work in that gun. The N80SB is also a 28Deg nailer so your 30 Deg nails won't work in that gun either. Sorry about the bad news but it looks like your going to have to spring for new nails

SOURCE: bostitch n80 does not feed nails

make sure that the feeder spring is not broken this stops nails or can jam them or cause them to skip. Some nail gun types work bette if you buy their brand of nails, but it could possibly just be dirty or maybe check the nail size. You should also have a way to adjust how far your nails are in the bucket where you put your nails, it should go up or down by spining it.

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.

My nail gun miss fires. seems there is not enough tension pushing the nails forward

Could be that the driver is not returning to top of the cylinder. Easy test, when the gun miss fires, remove air line, with thin metal, insert thru nose and push driver up. Retest gun. If driver was down a bit then nails will not feed. Remove head and check that driver oring is making good seal, lubed, and is not too tight or bent. Also check that lower bumper is not cracked or missing pieces. Replace parts as needed. If driver was all the way up, clean rails and pusher assembly with wd40 and follow with good cleaning with air. If pusher and rails working properly, must be problem with bad batch of nails, slightly thicker or wider head not allowing nail to easily slide. Open nose latch and check that nails slide thru easily.

I hav a coil nailer the problem coming is it fires double nail right after one blank shot , i hav tried everything by replacing its all types of O rings also changed the piston but the problem still...

Remove nails from the canister and test fire the gun very rapidly with side door open against hard rubber (old tire or coiled up rubber hose ) to absorb the energy. Look for driver and feeder to move in time together and driver should return to top each time. If feeder appears to lag behind, check feeder orings and air passage to feeder piston. If driver appears to come out out nose too far or if it does not go back to top every time suspect problem with bumper or cylinder check seal. Look at feed check built into the side door. These must make contact with nails to prevent miss fire. If all appears to look normal, replace the TVA6 valve if the firing pin fits/feels loose in body of the valve. Miss fire occurs when nail checks do not hold nails in place (feed checks on door and feed piston) and or the piston does not go all the way back up so the nail can not feed into place. Less often, miss fire is caused by lower bumper missing pieces /cracking and the crumbeling bumper pieces enter the feed piston chamber preventing the feeder from making full travel forward. One more area to check is the head /headvalve. Remove head and pull out headvalve. Remove fine scratches on surface of head where orings make contact (use 400 grit paper) and lube with silicone paste lube (sold at Lowes in the plumbing department). Finally check the cylinder seal sitting on top of the cylinder. It should fit very snugly against the cylinder and not turn. If it can be turned, replace with new or remove and apply RTV sealant and replace, then wait 24 hours before use. 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

I have a bostich m3 airnailer for hardwood floors and i dont know how to load it, i put the nails in, i smack the firing mechanisim it appears to go off but i pul it away and theres no nail? what am i...

The driver must be all the way up for nails to feed properly into place. Remove air and nails from gun. Examine the gun for driver neer bottom of gun. Driver could be broken or missing. If driver is neer bottom, push driver all the way up and test for proper action. If it only shoots one nail, time for oring kit or driver is bent. If it continues to work add only a few drops of oil as needed during use. If oil is coming out of nose, you have added too much oil. Parts are at www.bostitch.com. Good luck

Nail gun is miss fireing sometimes might only fire 1 in 4 nails fired

remove all the nails and remove the air hose. BUMP the tool on something and does the driver come down on its own if so it needs new o rings. also take a look at the feed pawl for a broken spring that would prevent it from feeding nails and lastly look at the coil of nails to make sure they pull freely. Let me know if you need more assistance.

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.

D51844 Won't Fire Nails

The Dewalt D51844 uses a full round head 20 degree nail. Sometimes the generic brand nails are not made exactly to the stated degree. They do this so their nails will work on a variety of nailers. Best to check the nails angle in relation to the angle of your nailer. Place a strip of nails on the outside of the rail. Align the heads of the nails to a convenient straight edge on the rail then check that the head and shaft of the first nail is aligned with the barrel. If the lower part of the nail projects out further than the head, then the driver will miss the head. If the head of the first nail appears close enough to barrell for the driver to hit it then place a new strip of nails into the mag and slide the pusher foward. Fire one nail, if success, remove the nails from the mag and check if the plastic holding the nails together is projecting in front of the first nail. Sometimes the plastic is not right, too stiff, and will not let the next nail align with the barrell. If the next nail appears ready and slides forward then the driver may not be going all the way up after shot. Check by inserting a metal rod into barrell and push driver up till it stops. If the driver is in the uppermost position, then most likely brand of nails. Use Dewalt nail. Good Luck
