Question about Tools & Hardware - Others
After using my nail gun for about 30mins, it stops firing out nails even though it fires as normal but no nails come out?
If gun firing but nails not being driven could be one of two basic problems:
1. Nail jammed in magazine not allowing nails to move up.
Empty magazine, does follower move to top of magazine. Push gun against work piece, does fan motor start? Yes - jam in magazine or lock out bar not operating. (this would allow nail un to fire when out of nails)
2. Piston/driver not returning fully after firing, hence driver blade on top of next nail instead of behind it. This could again be caused by a jammed nail or just a nail head. Another case of not returning is the combustion chamber not making a good seal, check O rings on framer (they are steel rings on bradders) it may just need a good clean it is surprising how dirty they can get and if not cleaned a build up of dirt could break a seal. If not been cleaned for a long time worth checking piston rings, worst case scenario dirt builds up around the rings and stick fully in requiring new piston if the rings will not come out.
Nail guns work on the principle that an explosion pushes the piston driver forcing a nail into the work piece, after the explosion a vacuum is created and it is this that 'sucks' the piston/driver back up the cylinder.

SOURCE: bostich gun problem
If the piston/driver is broken, the gun will fire however nailing will not take place because the piston will jam in the cylinder. Sometimes the cylinder will also crack when the driver goes. If the piston is not broken but stays down, then check the cylinder check valve, worn lower bumper, bent driver or cracked cylinder. 18 guage nailer has a very thin driver which will easily bend or break. Parts however are not expensive.

Hello. I can help you. The nail gun you have uses 18 gauge brads. I would use only original Bostitch 18 gauge.
The one MM of difference you mention is the reason why you do not have the pressure you did have. Get rid of those 31MM brads and get the 18 gauge. Home Depot carries the Bostitch line. I would go there or to homedepot.com

i found this happening to me and i oiled (light oil like 3 in 1) the driver (hammer) in the tip. that way it could retract and drive the next brad.
