Usually when you hear the pop of the compressed air and the driver does not move indicates that the driver blade is bent, broken, or stuck due to debris. Remove head and pull cylinder to examine. Parts are not expensice and are available as kit including driver and cylinder with related parts or just the driver. from WWW.bostitch.com or even ebay. If driver is bent, you can probably make adjustment and get more life. Good luck

How do I replace the trigger valve assembly on a Porter Cable DA250C nail gun


There is one pin with a retaining o-ring that must be removed holding the trigger arm in - then there are 2 roll pins that must be driven out with a small punch that hold the trigger valve. Once the 2 pins are removed the trigger valve can be pulled straight out.
When you install the new trigger make sure the recesses in the trigger line up with the holes for the retaining pins.

Bostitch F28ww nail gun does not cycle. There is no air leak or any sound when I press the nose down and pull the trigger. It is like it has no air at all. I was using it, it fired 2 nails at the same...


It sounds like your drive pin is jammed in the barrel. Can you see that moving freely? One of the two nails it fired may have lost a piece and is jammed in the barrel between the drive pin and barrel.
If this is the problem, You'll need to take a sturdy "drift pin punch" and hammer to drive the drive pin back down into the nailer. (I use an old drive pin from a discarded nailer as a drift pin punch)
Once the piston and drive pin are free again, the nailer should work fine.

Only shoots out one nail for every 4 or 5 trigger pulls


The gun will miss fire if the driver does not return to top position allowing nails to move into position. Could be bent driver, faulty trigger, cracked lower bumper or check valve not in place. Easy to check if trigger. Remove air supply, and remove the pin holding the trigger. Fire the nailer by depressing the firing pin with your finger. If the gun works ok, single fire trigger is faulty or safety foot is out of adjustment. If still miss fire, remove head and pull out cylinder and piston. Check for bent driver, cracked lower bumper or black band (check valve) is out of place on outer part of cylinder covering a row of holes.

The hammer in the gun is stuck in down positon, the gun is only 8 mos old. It also shoots sparks out when it nailed, thanks


No you need to oil these things even if you don't use them a lot you see condensation from the compresser gets in the gun if you don't have an moisture trap on the air line and even if you do you still put oil in the air fitting everytime you use it. So put oil in the front and back and hook it up to air and if you work it enough it will start working again

If the trigger still works to fire the single shot, then the o-ring kit should be sufficient. If the trigger area continues to leak air, then the trigger should be replaced as well. Keep the gun well lubricated as well.

The nailer shoots a nail when the trigger on the handle is pulled irreguardless of the hammer being used to strike the head


I found a broken retainer ring in the head of the nailer. It had the striker head jammed in the down position so when you pulled the trigger to arm the head with air pressure, the flooring nailer shot a nail.
Thanks ..
