Hitachi Wh18dl 18v Liion Cordless Impact Driver - Page 2 Questions & Answers
My hitachi nt50ae2 will not work when I try to use 2 nails.
1) Oil it per the operating instructions.
2) Use only high-quality fasteners. I recommend Hitachi or Bostitch, although those from Harbor Freight Tools are largely trouble-free.
3) Make sure nails are properly inserted in the gun.
4) Check to confirm that your gun is receiving adequate air pressure. With that nailer, I'd suggest 95-105 psi.
My hitachi nr83a nailer cycles one time when the air is attached. After the initial cyle the nailer operates normally.How do I repair it?
This is not a common problem for your nailer. Indicates a small leak in air path from triggering valve to head cap assembly. Assuming that there are no external air leaks, I would clean and lube the cylinder. Try to smooth all the fine scratches that you see on the cylinder where orings make contact. I use very fine sandpaper and turn the cylinder with a drill attachment. (you can be creative with an attachment, like a round piece of wood 2-3 inches in length that fits snugly into the cylinder find center and screw in a 1/4 in diameter screw, cut off head of screw.) Place your homemade attachment onto drill and slip into cylinder, the wood attachment will not damage the cylinder. I use a variable speed drill and turn slowly while I hold a strip of sandpaper against scratched area. Just a light even sanding is all that is needed. If not too scratched just leave as is. Replace oring number 877316 for cylinder plate (outer) and 877327 packing and lube with white grease. You do not have to replace any other orings unless they look damaged. If you replace all the orings, the cylinder will be too tight and my not work at all. Make sure that the three bolts on top of head are tight (no need to remove them, just make sure they are tight). Good luck.
Hitachi nr83a leaks air at new g.asket between head cap and body. screws are tight
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.

How do I get the cap top of a Hitachi framing nailer back on.
NV65AD3 or that kind of ?
NV90AB2
on the biggest transparant plastic part that will fitt on the upper part and the squill will fitting in. with a well-fitting pipe wrench that fits just in the rounding so you can control it somewhat fix the upper part in a bench vise then push with the pipe wrench around 20 mm or maybe some bigger it to its place and with both hands you can push it on place, a plastic hammer is not allways necessary .
