    whe i push trigger it just pops at the trigger and nothing happens ? When it quit i was using it and the push rod stopped at the full out position and the trigger started popping when i pushed it. I checked o rings in the body and they looked okay. I pushed the rod back down, oiled it well and still had the same problem.

    I have a craftsman framing nailer that leaks air from the trigger when depressed and does not fire a nail. I borrowed the gun and it worked for two days when this issue occurred. I bought the "trigger kit" from Sears parts direct and installed the new trigger plunger and o-rings. The gun worked for two days, maybe fired 150 nails and then the same issue has occurred again. Is this gun just a POS or is there some fundamental issue I have?

Where does the air leak out from? If it leaks from the trigger DeWalt makes a trigger valve assembly part # 641006-00 list 8.89 BUT if it leaks from other areas we have to look into it deeper. If it is just the trigger valve let me know and I will give you instructions how to remove and install the new one.

My 18 gauge Bostich brad nailer would not fire, and air came out around the trigger. Even though the gun is advertised as oil less - this is what remedied my problem - a drop of oil. I put one drop of oil in the slot where the brads come out [realizing that is where the driver is located] and left the gun upright for some time. The next time I used the gun it worked just fine. A drop of oil can also be added into the gun where the air hose is hooked up. Do not over-do the oil process, but don't ignore it.

The trigger on my senco 502 nailer will not compress, ie will not fire. Why and what parts if any do I need.


Check the manual if you have a safety switch. Also check for any bent nails inside the gun. Make sure all is OFF before investigating.

I pull the trigger and you get a air sound but no firing of nails . You get air release from top of gun


Could be just a lack of lubrication in the headvalve /orings or the safety foot is not pushing in the trigger pin all the way. Easy to check. Remove the head and pull out the head-valve. Apply plenty of white grease or silicone paste to the orings and the surface where the orings make contact. Install the head and test. If the gun fires then you are done. If the gun does not fire, make sure that the safety foot is depressing the trigger valve all the way in when attempting to nail. Simple test is to remove the trigger exposing the firing pin. With nails removed and air connected, with quick motion depress the firing pin all the way in. If the gun fires make adjustments to safety foot. If the gun still does not fire (with headvalve lubed) replace the firing valve core part # ca0108. Good luck

I have seen this on dewalt and p/c guns. Usually caused by trigger valve but you mention that trigger valve is new. If the headvalve does not seat correctly on the top of the cylinder, the in-rush of air will leak past cylinder seal and push down the piston (feels like you fired the gun ) . Difficult to pin down the problem but could be headvalve is sticking slightly open. I would suspect headvalve orings too tight or spring in head is weak or cylinder in head is worn. Easy to check. Remove the head and push in the headvalve with thumbs. The valve should be stiff to depress but return freely. Check that the cylinder in the head where the outer headvalve oring makes contact is not scratched or worn. If scratched, sand with fine sandpaper till smooth. If worn and depressed, replace head. If spring feels weak, stretch it a bit pulling it apart. Lube cylinder /orings with white grease. Untill you find the problem, do not load nails untill after airline is connected. On the dewalt guns, firing when air is connected is due to the trigger firing pin orings worn. You could check this on your gun by spraying soapy water on the trigger valve under the trigger then connect the airline. If air is blowing out the trigger when you connect air, most likely faulty valve. Good luck and let me know what you find out on the unusual problem.

I have a hitachi nr90ae that will not fire. Depress nose and trigger and gets nothing. What's next?


Remove nails and air supply. Firmly depress safety foot against work with trigger depressed and make sure that firing pin is pushed all the way in. If firing pin is being activated by safety foot most likely problem is stuck cylinder or head valve. If the gun has been dropped the cylinder my jam. Remove the head and make sure that the cylinder and or headvalve moves and that the driver is not stuck in place. Good luck

Hitatchi nv45b2 trigger leaking


Air leaking around the trigger area could be caused by vinyl ball / gasket under trigger valve bushing or orings within the gun. Easy test, remove nails and connect air (assuming that air is now leaking around the trigger area). Depressing the trigger stops the leak, replace vinyl ball. Depressing trigger does not stop leak, move plunger b (plunger B, small shaft under bubber bushing next to the trigger valve) with your finger in then out to determine if air leak changes tone. If air leak changes sound or tone, then air is leaking past orings of the cylinder guide and/or cylinder plate and/ or the cylinder itself is scratched by debris where the orings make contact. Pull out the cylinder and examine the contact areas. If scratched, use 300 grit paper to smooth, if smooth, however, suspect the orings of cylinder guide (or cylinder guide is cracked). The cylinder guide is difficult to remove and install without causing damage to guide or cutting new orings when installing. Do not remove the guide unless all the other options have been checked. One last bit if information, I have noticed that some guns will leak air if the orings on the feeder piston do not fit snuggly. Make sure that leaking sound is not coming from feeder area (remove the basket and feeder/feeder pin/spring and pull out the feed piston, making sure that the largest oring is making good contact within the cylinder). Good luck with repair.

Remove the nails and air supply. With side door open notice position of driver. Driver should be at top position with tip not visible. If driver is down and it moves within cylinder when you tilt nose up then down again, time to replace orings. If driver is down, it should extend past the nose about 1/4 inch (if driver is broken at the tip the end will look rough and nail will not drive in all the way). If driver extends past the nose more than 1/4 inch then lower bumper may be breaking up /cracked. Easy test for proper function. With nails removed and side door open, connect air to gun and dry fire gun against hard rubber or old coiled air-hose (with air connected and trigger depressed, no air should leak from trigger area, if air leaks when trigger is depressed, look for fault at trigger pin). Feeder should move back then forward in quick motion almost matching speed of driver and driver should not creep down between shots. No air should leak from nose of the gun (push nose against hard rubber and depress trigger and hold in this position, driver should stay down with very little or no air leaking out of nose, when you release trigger, driver will return). If air leaks out of nose while holding in this position, replace lower bumper. If a quantity of air leaks from valve in front of trigger, cylinder orings may need replacing or outer part of cylinder has fine scratches (remove scratches with 400 grit paper). Parts are available at www.toolpartsdirect.com. Good lucki

Paslode nail guns won't shoot


piston is probably jammed

This happens sometimes try holding it up against a board with the trigger depressed and then inset the battery.

The goal is to try to force the firing sequence to get the piston back to the right position with corded units this is simply done by attaching the air hose with the trigger pulled this causes air to rush into the gun chamber pushing the piston back and firing a nail out.

The cause of this is a misfire or jammed nail that stopped the piston in the wrong location so air will not build in the chamber correctly.

Hope that helps

Once trigger is depressed, air leaks and no nail is fired....


Sounds like the trigger o-ring is damaged, either because of not being oiled frequently, or the pneumatic tool has not been used for a while. O-rings will harden up if not used. Look for a place that sells fasteners, or nails and see if they can put a new o-ring in the trigger asm. for you. If you take the gun to a place where you purchase your nails, they should repair for little or no cost. it is an easy repair if you have the tools, parts, etc.
