Question: Porter Cable BN125

My brad nailer won't fire. I hear air escaping when I press the trigger and there is no resistance in the trigger pull.

Hello sacs64,

The problem may be with worn or torn o-rings in the trigger assembly. Part number 903754 will replace all the o-rings in that assembly plus other o-rings in the gun to get it tuned up and firing like new.

Hope this helps,
-WJA

Question: Porter Cable Bn125

My brad nailer does not retract each time I drive a nail. I have to push the piston up each time to drive another nail. Whats the problem?

Reply: Porter Cable Bn125

Usually that's due to low air pressure. Increase your pressure a little but make sure you don't go over the recommended pressure- I rarely go over 110 psi for any of my nail guns. Your gun need air to retract as well as to drive.

Question: HOW TO FIX

My brad nailer shoots one brad without jamming but it won't pickup the next brad. I can slide the driver up and it shoots one again. What is the problem?
