Hitachi WJ200-015SF AC Drive, 1 Phase Questions & Answers
Hi, I have been stumped! I rebuilt a Hitachi
This is the Cars and Trucks section of Fixya. You might get more answers listing in another area of Fixya which more closely matches your device.All things considered, maybe apply air pressure and stick the unit under water in a utility sink or big wash tub. Air leaks would bubble like a hole in a tire tube.
Hitachi nailer doesn't fire, it has no leaks. When trigger is pulled there is no back pressure from trigger
I've had that happen before and what I found was one of the Staples or nails had misfired and wedged before leaving the gun. read the manual on how to get to it for that particular model and also it might be a good idea to adjust your pressure accordingly to keep it from happening again. If the force isn't set proper then a nail could Jam , block the mouth and not allow any other nails to exit. It's very easy to do and not that hard to fix once you've done it at least once. Good luck.
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.
