   I don't have any Bostich guns, but all guns need a little maintenance now and then.  Some cleaning and a light lubrication usually clears up the nail feeding problem.

   The first thing I did was remove the protective cover around the tip and emptied a can of carb cleaner on it and used small brush to remove any deposits. Hosed it down with WD 40 continued to brush off any deposits..........still won't feed nails.

   thanks though

   Hey, worth a try.  Will it feed if you manually force the nails up?  Like the spring is gone?

   Its a coil nailer. I've tried the archives not much is said about when the nailer breaks. When the piston comes down another smaller piston moves the nails. My guess is the gismo that grabs the nails (fixed to the smaller piston rod) isn't grabbing the collated nails when it cycles. If I open the latch to the piston area, the nails are bunching up at the bottom

   Once you've cleaned the crud from the nail advance pawls, check/clean/rebuild the advance piston. This small piston is behind the nose, on the right side. It pushes the pawls to advance the coil.

   Would a rebuild on the advance piston also include gismo at the end of the advance piston rod that actually moves the colated nails???.  It looks like the advance piston is moving

   Probably. A pro nailer shop fixed this particular problem. They told me what they'd done. ;)

   The gizmo looks like a short pivot link, with a removable lynch pin. I think I see a release clip there, under the crud. An advance piston kit might include this link and lynch pin.  ;)

   Spray the *.* out of that area, wipe, oil, then cycle the gun without nails in the mag. 1. Do the pawls move? 2. Does the piston take a stroke? 3. Does it return to its position? The driver blade will cycle when you do this test.

   I have the magazine off. The front/right cover off so I have a clear view of the advance piston and everything looks fine. Piston moves back to its orginal position etc. I can take a screw driver and push on the piston rod and it moves smoothly.

   I don't suppose a bad batch of nails would cause this. Example- the spacing between the nails isn't right? The nails are bostitch 3 1/4 galvanised ring shank. You'd think they'd be ok.Thank you for the tip

   So the advance piston moves back and forth, and I presume the pawls do as well.

   Try this: Make sure the plane of the nail heads feeds in the slot between the two positioning ramps. It is easy to misfeed them in the lower of the two grooves.And make sure the coil is not deformed. A deformed coil will mess the nail-to-nail spacing. Sometimes, one of the nails pins itself into the coil. This prevents nail advance.

   curious...

   How 'bout the piston for the driver itself? Does it cycle? Any air leaks? I never gave much thought to what drives that little piston in the first place but seems logical it would be air driven as well. Bostitch uses air recycled from the driver piston to return the piston so it could be something wierd like that.

   In other words I don't know either but am curious.
