Questions & Answers

Nail gun does not pick up the next nail. It makes an impression in the wood as if it is firing fine, but no nail. No air leaks noted. I have reloaded with different nail. The ones I am using have worked numerous times before so its not a nail issue. I opened the nose piece and don't see anything unusual. What would be the most probable cause? Thank you.
David for model number FN250A 16GA Finish Nailer
Hi David, Thank you for your question. If the gun is firing weakly or not at all, check the compressor. This is the power source for the gun and is where the air comes through. Consider tightening the air pressure. I hope this helps. Thank you and have a great day!
Nail gun stopped firing after shooting several nails. Now all the air blows out of the end cap and pulling the trigger does nothing.

Gasket - 886114
Piston Stop - 886113
Urethane Retainer - 890725
Repair Difficulty:
Medium
Time Spent Repairing:
1-2 hours
Tools Used:
Wrench Set, Allen Wrenches, Needlenose Pliers, Air Tool Lubricant.
Pneumatic nailer intermittent fire, sticking.
In addition to a new piston bumper and manifold gasket I installed an O-ring kit. I started with the firing mechanism valve assembly which unscrews from the body using a box wrench. I cleaned the valve and fitted new O-rings the lubricated and reinstalled. When there was still a problem I disassembled further and found that the piston bumper had been dissolved after someone had tried to clean the tool with solvent. I removed the manifold cap, piston and cylinder and flushed the unit with WD-40. I wiped and dried all pieces then lubricated all O-rings and reassembled. The most important thing to remember is to properly reinstall the neoprene band that covers the small holes in the middle of the cylinder. The band acts as a one-way valve allowing the pressure charge to vent into the outer cylinder chamber where it then forces the piston back up completing the firing cycle. Everything else is step by step except for the band since it will slide out of position during disassembly and unless you know where it goes back your tool will fail to cycle. A little study and you can figure it out if you don't know.

Porter Cable finish nailer was missing every other nail, and then every nail. Took it apart and piston bumper was falling apart.
Clean all the pieces out from the broken piston bumper, and clean muffler. Install new bumper, make sure when installing top portion of piston not to dislodge o-ring, I did and it leaked air when I put it back together, took back apart and saw it had pulled out, just take time and align piston when installing, goes in easy and properly. Put back together, and shooting like new. Hope this helps anyone.

Pin fell out and trigger fell off during operation. Urethane retainer on pin came off and was lost.
Lined up trigger with pin hole and inserted pin and retainer. eReplacementparts phone operator identified the urethane retainer on list, but it was not shown on the manufacturers schematic nor on my list that came with the tool. Good job by eReplacementparts. Nose cushion wore out and was easy to replace.

Original pin on my nail gun lost the retainer clip then the pinon the trigger.
Simply inserted the new pin and placed the retaining clip on the end.

The biggest challenge was finding a replacement part. Your site made it simple.

    Nail Gun Trigger
    I found the part easily on the site diagram and was easily installed. I thought I had lost the c clip but by watching the video I saw that it was this urethane retainer that needed replaced. Ordering was easy, shipment was relatively quick, and my nail gun’s trigger is again in place.

    Better quality than I was expecting and installation was easy as it gets. Nail gun fires fine now.
