Product Description: If air is leaking from your nail gun exhaust, you may be in need of a new piston head valve. The head valve is what regulates the air flow into the cylinder. This OEM head valve is sold individually. Over time, the seals on this plastic part can harden and break, and the valve body itself can also break. For this simple repair, start by removing the head from the nail gun, and then remove the worn valve from the head. There will be O-rings on the valve, which should be inspected and removed, this is a good opportunity to assess their condition, and replace them if needed. They are sold separately. You will then remove the steel washer located in the bottom of the head valve. The O-rings can now be reassembled back onto the new part, and you can begin to reinstall everything.

I do not know how to get the head cover off this nailer. Most Bostitch nailers have 4 Allen screws holding it in place. This appears it just snaps on, but to not want to remove it as I don't want to break it.

For model number N66c-1

Hi Vaughn, thank you for contacting us. We have researched your model and found that four screws keep the head cover in place. You need to unthread the screws to remove the head cover. We hope this helps.
