Bostitch f21pl nail gun leaking air from exhaust

SOURCE: air coming out the trigger of a stanley air gun

Go to the Stanley Bostitch website. Click on schematics & parts. Find your model number in the drop down list. There is a list of parts and pricing. Just above the parts is a link for the schematic. Honestly, I worked on these things for years. It is best to replace the entire trigger valve. It comes as a kit with instructions grease, and a little tool to hammer your pins out. Lemme know if this helps. Please rate me

SOURCE: contact head won't retract...seems to be stuck

Two things come to mind, both require disassembly.

First i would clean the area, and then relube the contact head. While cleaning that area and relubing, check the o-ring and the surrounding seals, they may be not properly alligned or sitting perfect.

I don't have a lot to go on here. Can you describe what does happen? Is there any release of air at all? You can try checking the o-rings for leaks. There are o=ring kits available for under $20 that contain all of the o-rings. Also, proper lubrication is required for operation. If the main plunger chamber does not have enough lubrication, the plunger won't move properly and not set the nail.

Please update this with any details you can.

Thanks,
Dan
