When the driving pin #9 won't stay up inside the tool, it's time to replace its o-ring. You'll find this procedure to be quite easy after you've been through it once.
To Replace O-Ring #507 on the Driver #9
Using the Allen wrench provided in the tool case, disassemble the tool in the numbered order shown in the diagram at right. Work on a clean surface, setting out parts in the order you remove them. Have a clean rag handy, because parts should be cleaned of dirty oil/grease before reassembly. Don't bother to separate part #5 from part #4:
part #8 will need help being removed. use a small, long-shanked screwdriver, a spike, or rod about 3/16" in diameter by about 5" long inserted into the nozzle of the tool. Push or tap the end of the rod until #8 is released. The drive pin number #9 also will be released. The o-ring #507 is on the piston bonded to the drive pin and probably will look worn flat. Replace that o-ring with a new one and check the inside of the smooth cylinder for dust or other debris, wiping it clean as necessary.
Liberally apply air tool oil to parts as they are reassembled.
Place the drive pin #9 into the cylinder. to get the end of the drive pin to slip down into the nozzle may take some perseverance.
Try rotating the top of the piston (the surface facing your). that often causes the drive pin to center itself and drop into the nozzle as is necessary.
Once the piston can be pushed down into the cylinder, add 2 or 3 more drops of the oil into the cylinder. Then replace each part in reverse order, PUTTING THE CORRECT SIDE UP. Be sure each is oiled liberally.
Parts 2 through 4 will need held down against the tool body while starting the screws. Don't tighten any one screw until all screws are finger tight. If a screw doesn't start easily, don't force it. Be sure it is aligned.
Connect the tool to air. it may leak air until fired one or two times. If it continues to leak air, you should repeat the disassembly and assembly procedure. Along the way, you may discover that the part number 6 is upside down, for example. If your efforts are unsuccessful, feel free to e-mail or give us a call.
Eventually, you may find that the other o-rings (there are 17 total) need replaced. We have o-ring kits available for purchase.

Nail Kicker O-Ring Wear
Some customers have expressed concern at how quickly o-ring #507 seems to wear out. It is the part that receives the most wear. The factory expects that o-ring to last 100,000 to 150,000 cycles. If the tool is used heavily, that number of cycles can be reached in as few as 3 weeks. We are working with the factory to get more cycles in future tools.
Also, we're discovering that the tool, when used heavily, probably should be oiled 4 to 5 times per day, not just 2. Each user will learn what's necessary for their operation. The dust cap should always be on the air inlet port when not connected to the hose. (Also, shake any dust from the dust cap before capping the air inlet port.)
We're here to provide the Deconstruction and Reuse industry with tools to make your work more productive and, frankly, easier. Please feel free to keep us informed of tools you'd like to see in the future.
