HI, if it happens when you press the trigger the top valve is sticking & your gun needs servicing.
If it is just leaking by itself the trigger assembly needs serving or you can replace the trigger unit. They are not expensive & come as a complete unit (depending on the model).
Moselikely the orings are worn out or dirty
cheers

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

Bostitch framming gun sticking?


Most likely the headvalve is sticking. An easy fix would be to remove the head and lubricate the headvalve orings with white grease or silicone paste. The upper bumper should not have any cracks. If the problem continues replace the trigger valve (tva6). The trigger valve can be bostitch or generic sold on ebay for usually less then $20. The trigger valve has an inner valve that can stick due to swolen or hard orings.

Hi i have a problem with my stanly bostitch nail gun .i was using it ok for a little while then the nail stop coming out ,now all i hear is a putting sound only ,sounds like no air ,but my compressor and...


Your nailer model number is N75C-1 shares design features with many other bostitch coil nail guns. Usually, when you only hear a puff of air coming from the trigger area or within gun, the driver or headvalve is stuck. Usually easy to fix. First check the driver by removing air supply and inserting metal rod into nose of gun pushing the driver all the way up to top of cylinder (open latch and note position of driver, should not be visible). If driver is stuck due to debris, clear and retest gun. If driver is all the way up then remove head and see if the driver moves down (should move with light pressure). Headvalve should move inward with strong thumb pressure and move back out. Repair as needed and lube with silicone paste lube (sold at Lowes in plumbing department and swimming pool supplies). If both driver and headvalve look ok, then suspect trigger valve under the trigger. Good luck

Instructions to install trigger assembly in n60fn air nailer


Easy to do. Use 3mm roll pin punch to remove pins at trigger and one or two pins just above the trigger valve in the body of the gun. With pins removed and trigger out, nails removed and with a gloved hand, apply air pressure to gun to pop out the valve. Use caution because the valve will come out with force if air pressure is too high (reduce air pressure at compressor). Make note of grooves cut into the old trigger valve in relation to how the valve was aligned and held in with roll pins. New tva6 valve is sold on ebay for under $20. Good luck

Trigger problems


I have repaird hundreds of nail guns with a problem similar to yours. Depending on the brand and model, the problem can be repaired by checking the following. Headvalve orings should be checked for wear and any surface that the orings contact must be smooth and free from scratches. If the surfaces are scratched try to smooth with fine sandpaper and use light grease instead of oil when assembling. The safety contact foot may not be reaching high enough into the trigger to properly push in the trigger button. Check for worn spots on the trigger that may be filled in with epoxy, loose fitting trigger caused by worn roll pin or retaining pin. Some of the trigger valves as used on many bostitch nailers (tva6 valve) used a plastic pin which contacts the trigger. If this pin is loose or worn the valve should be replaced. Some tva6 valves have a vinyl looking sort of oring that fits too loose on the spool. This vinyl oring in not available by itself but if the oring fits too loose the gun will not fire and leak air. On bostitch remove the trigger and the rollpins holding the trigger valve and apply air to gun to eject valve. (use heavy glove to catch valve as it will come out with force)
