Pressure builds correctly and it is sending air thru gun but won’t shoot nails.

Nothing jammed….every once in a while it will send a nail out.

Not knowing the compressor make and model makes helping you more difficult.

The tank pressure reaches the normal cut out and the compressor stops?

You pull the trigger on the nail gun, and sometimes, but not always, the nail is driven?

That’s typically a flow problem, and I would surmise that your air regulator is impeding sufficient flow.

What pressure does the nail gun need to receive to work properly, and what is the regulator setting on your compressor, please?

6 gallon 160 psi tank. FN250C finish nailer.

Porter Cable FN250C finish nailer

Porter Cable FN250C finish nailer

 

Regulator pressure at 80 and tank pressure at 120.

When operating, gauges correct…when I pull trigger, it sounds normal with air coming thru hose and gun, but nail not coming thru.

There is no jam in nailer.

Set up the nailer, pull the trigger with nails in it, and while pulling the trigger, watch the regulator gauge.

It should blip a bit, but not drop way down.

It sounds as though the regulator is impeding flow.

Has this particular setup worked OK in the past, or did something change?

Turns out the nail gun needed a few drops of oil…it now works fine.

Sometimes it’s the little things that are overlooked.

Thanks for the update.
