    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.

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.

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 Bostitch N80S stick framing nailer that leaks air from the trigger area. I replaced the entire trigger valve with a new single fire trigger to see if the old bump fire trigger was the problem


Remove the nails and take off the trigger to expose the trigger valve (usually part # tva6). Connect air and spray soapy water on the valve to determine if the air is leaking from the center of the valve or around the outer edge between the body and valve. If leaking from the center, could be defective valve or debris under oring. Pop out the valve and examine internal parts for cut oring or defect. If leaking from between body, you could have cut orings installing the valve. Make sure that there are no rough edges in the body of the gun. Bump fire or single fire happens with the trigger type not the valve. Bump fire trigger is usually black metal and single fire trigger is light color plastic. Good luck

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

Gun will not shoot nails completely;no matter what wood,thickness,etc.they drive all but 1/2"


May be due to broken tip. Easy to check. Remove nails and leave door open. With door open, lightly tap the nose of the gun against coiled rubber hose or soft wood. The driver should stay at top position. If driver falls to bottom of the cylinder, replace piston oring. Now press nose of the gun against old coiled up air hose or soft wood and squeeze and hold trigger. The gun will fire and the driver should stay in the down position untill you release the trigger (if not single fire trigger, if single fire trigger remove trigger and press the trigger pin with finger). While the driver is down, make sure that the tip extends past the nose about 1/4 inch (if air leaks past the nose in this position, replace lower bumper). If the driver does not extend past the nose, replace driver. Good luck

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

Air leaks arond trigger when depressed, but no nail fires.


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.
