I have 3 Hitachi benders VB 16Y and works only when it wants too. I plug in and press trigger and some times works and other times does not work , also checked the brushes and there is plenty left.

I know nothing about these tools but Hitachi produce quality gear that isn't usually prone to intermittent faults. If I was faced with your situation I would check the power cord for internal breaks and check the internal connections and then investigate the functioning of any safety device that might be incorporated into the design - such a powerful tool would surely have safety built in or modern legislation would never allow them to be used on site. It was just a sort of gut feeling as it seems to be the built in safety that fails on many tools...

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.

Hi I have a hitachi gas strip nailer it doesn’t fire I have changed the spark plug and checked the adapter the adapter is ok the spark plug is new but still not firing is ther anything else I can do any information would be appreciated Thank you Danny

The number one issue is bad fuel - even if you just purchased it, turn the cell over and check the date stamped on the bottom (often stores don't rotate their stock) If the fan starts when the nose is depressed but there is no spark then I would investigate the spark wire (make sure there are no nicks or cuts that may short to ground) and the ESU (Electronic Spark Unit).

I cant get my hitachi nr90ae nail gun to fire

Have you kept it properly oiled? It might be jammed because it's too dry.

HITACHI NT65MA4 When not used for a few minutes, doesn't want to fire. Holding trigger down for a few minutes and eventually fires. Then works fine? What causes long pause?

Sounds like it's overly dry; needs oiling. Or there is something clogging the air lines or the air chamber inside the gun.

My brand new Hitachi roofing nailer emits a mini whoosh of air (from the ball the trigger pushes on, I think) as I depress the trigger, but stops when it it fully depressed. Is this normal?

It sounds like you're producing difficulties yourself by attempting to solve this problem rather than seeking at why their can be a difficulty inside very first place https://www.fliptite.com/

Hitachi ng90c2 won't fire , full gas and battery.it goes through the normal procedure but nothing happens when I press the trigger to fire a nail.

Check the date code on the bottom of your fuel - it doesn't matter if it feels full or that you just bought it, many stores don't rotate their stock. The #1 issue with these is bad fuel.

My hitachi nt50ae2 will not work with 2" nails no matter what brand I use.

1. Have you adjusted the air pressure to at least 100 PSI? 2. Have you cleaned and lubricated the gun per manufacturer's instructions? 3. Are you driving nails into hard wood (oak, walnut, etc.)? Some guns are simply not powerful enough to handle extremely hard woods.

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.

My hitachi 2nd fix nailer isn't charging, I put the batteries on charge and after about 2mins the light turns off and they stop charging. How can I fix this. Cheers

how old are the batteries. how old is the charger. if one or the other is too old or defective, the bad part will "fail safe"the system. shut down so it doesnt explode or burn if it does it with multiple batteries its probably the charger.be sure to check your electrical source too. bad outlet?? be careful these batts can be dangerous. ,
