This sounds like it might be a problem with the nails themselves. Have you tried another brand? If the place you got the nailer is nearby, ask them about the problem. Also look if the carrier strip MIGHT not be clearing and preventing the advancement of the nails. I would also try a light spray on the coil of CRC226 available at Home Depot in the electrical dept.

SOURCE: My RN175 shoots you think it shot the nail, but when you move the gun to shoot the next nail the nail you just shot falls out the end of the gun. What could cause this?

The driver is coming down far enough to break the nail off the strip but not far enough to drive it in. This could be caused by any of the following:
- The driver is broken off and too short to drive the nail
- The driver is bent and doesn't travel all the way down
- The seal/o-ring on the piston is damaged and air is leaking past it
Any of the above will require you to remove the head and inspect the driver, piston and o-rings or have a service center check it out.

Stop using it and take it in for service. If it is leaking air then an o-ring or seal may have failed (most likely guess) and it needs to be replaced.

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.

Senco fram pro 602 nail gun firers but no nail just a hole from firing pin


First, check that you are using the proper nails. The FP602 needs Full Round Head nails with plastic collation. If you are using Clipped Head nails with the paper tape collation the angle of the nails not let the driver catch the next nail and drive it into your work.
If you have the correct nails, check the magazine to make sure the nails are feeding all the way up to the driver. If there is anything blocking the way or if the spring on the feeder isn't taught enough to pull the clip all the way up the driver won't be able to catch the next nail and drive it in.

Did you rebuild the tool? If not remove all the nails and unplug air, BUMP nose on piece of wood and does driver fall down? If so the pistion o ring needs to be replaced. Also if this is not the case look for a jammed nail in the magazine/nose area. Next check for a bent driver blade. All the above could cause your problem

Nail feeder on this gun is both air and spring controlled. Air pressure retracts the feeder and a strong spring pushes the feeder back to front. Remove nails and leave side door open. Dry fire gun very rapidly against thick rubber pad and watch the feeder retract and return. It should move very rapidly all the way back and front again. If it appears to move slower than piston is moving then follow next step. Pull the feeder back manually with tip of screwdriver. It should be very hard to overcome spring. If spring feels strong then suspect feedpiston oring or air supply to feedpiston chamber is restricted with debris from inside of the gun housing or air is leaking where body of gun mates with lower nose. There is a small white oring that seals between body and nose base. Sometimes this oring will be over-compressed thus restricting air flow into feed chamber. Remove two allen screws at front of base to split body from base and reveal this oring. Parts are available at www.toolpartsdirect.com. Good holidays

This is an easy fix luckily usually it means that the chamber is dirty and all you have to do is open the top front of the gun so that you can see the piston then take a q-tip and clean the area really well sometimes it requires a degreaser and then when you think that you have it clean make sure to lubricate the chamber really well with the paslode lubricant that came with the gun or they sell it right next to where you get the nails. Then the gun should work fine with no problem if this does not work then this means that the piston might be bent and that could turn into a big problem but is still fixable just harder.

Hope that this works for you

Bostitch nail gun loss of pressure, won't fire nail


Hello. I can help you. The nail gun you have uses 18 gauge brads. I would use only original Bostitch 18 gauge.

The one MM of difference you mention is the reason why you do not have the pressure you did have. Get rid of those 31MM brads and get the 18 gauge. Home Depot carries the Bostitch line. I would go there or to homedepot.com

Feeding nails


Your nailer shares design features with Milwaukee and Ridgid. All three brands experience the same issue. Lets go thru a series of simple tests to determine the problem. First and most simple test, manually load the nails and fire the gun untill miss-fire. Upon mis-fire disconnect air, open latch and check if the driver is all the way up into the cylinder or is partially down blocking next nail. If driver is down blocking next nail, replace the driver oring and retest. If driver is up all the way, remove nails, reconnect airline, leave latch open and fire gun against rubber (old tire or coiled up waterhose/airhose) this time holding the gun down and keeping the trigger depressed. In this position, the driver will remain down and feeder will remain retracted. With feeder retracted and screwdriver in hand carefully check the spring tension on the feeder (should be rather firm tension on spring and the feeder must retract with good force). If no tension or weak, replace feed spring. When you finally release the trigger, the driver will retract and the feeder should return with good force. If feeder does not return with force, replace orings and spring behind feed piston. If all tests are ok, remove head, check lower bumper in gun for cracks or missing pieces. Replace as necessary. Lube all orings with silicone lube available at Lowes in the plumbing department. (Danco brand) Good luck on your repair and email your questions.
