Sorry, we couldn't find any existing installation instruction that matched.

Tool is an RN46 bostitch roofing nailer. The nailer leaked air and would not fire.

I removed the 4 screws at the head, removed the top sleeve seal and two o rings and replaced with new. the gun works as new now. It is amazing how little wear on the seals can cause pneumatic air nailer to not function.
