Question about Hitachi Tools & Hardware - Others
If its constant leaking inside the nailer (not between cap and body to outside feeling an airstream in front or on one side )then there is an problem between top seals VALVE and seals o-rings on top of the piston cilinder the parts on the top of the cilinder Seals and in the top in high priority must all be replaced because of the building up heat overtime the gaskets seals and o-rings are getting hot and hardened out over time there are only separate parts selled one by one to get I have not seen hitachi gasket/o-ring kits for nailers there where only complete kits for the older range of demolition hammers , but in the new models not anymore outside the States m,aybe but in Europe not. replacing the piston bumper could sometimes help extra because of the little height difference of the cillinder .
If leaking between cap and body with a palpable airstream and before the seal was closed tight , retapping the treaths some greater in the magnesium body and place helicoils inside it could be bad treath in one of them , it must put firmly fixed that will not fasten enough that was with the Brand Dutack Pro a high priority problem for a few years ago exact the same a few years now its modificated and that problem is gone.
