I would recommend going to Senco.com and you will find a complete parts diagram in their discontinued tool section.

The driver should not move from the top of cylinder position. If driver is moving up then down replace the driver oring. If driver oring seems ok then connect air supply and bump fire the nailer without nails against soft wood and door open so that you can see the driver and feeder moving. Bump fire the gun and make sure that the driver is moving all the way back up to top of cylinder and the feeder is moving rapidly back and forward. If movement seems ok then hold the nose down on soft wood and depress and hold the trigger. This will fire the gun but driver will stay at the bottom position and not return until you release the trigger or lift the gun. When holding the gun with the driver down position, no air should leak out the top or bottom of the gun.

If air leaks out bottom, replace lower bumper, if air leaks out the top replace the upper bumper. Good luck Mar 19, 2015. 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. 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. May 10, 2011. A nail gun works on compressed air.

When you hook the air hose to the gun it fills a cylinder with air pressure. When you pull the trigger. The cylinder pressure is released onto a firing pin that shoots the nail. The air pressure line is also connected to the trigger and therefore the trigger has to be sealed.

When ever using a nail gun, you add a bit of gun oil in the back of the gun (not 3-in-1motor oil, it has to be non-detergent gun oil) If you haven't used the gun in a while, it is best to oil up the gun and let the oil run down into the gun. If you use anything but gun oil, the seals will give out. Your trigger seal has given out. It is probably an 'O' ring. You can access it by taking it apart. Look for the O ring. Bostich makes re-build kits for the different guns that you can buy on-line.

Back when I was in construction, there were several nail gun shops that sold and serviced nail guns, and sold nails to the contractors. I don't know if that business model is still active or if you have to send the guns to Bostich service center. Oct 18, 2010. Stuart - this sounds like an air problem - you should perform the following test.

With the air nailer close to the compressor you must monitor the airpressure after the gun fires. It sounds like the air is not gettting through diapram fast enough or there is a blockage in line. Blockage in line is not suspected for the following reason. It sounds like the air hose is holding enough air to fire 2-4 nails and then you must wait for the line to fill up again and then it fires ok.

The pressure regulator out to the line controls this and they do fail. Try this test and report back to me - I know I can solve this for you as I have extensive background in compressor and the like. Oct 22, 2008.
