What to do if nails clog the mechanism of my Hitachi NR 90AE Nail Gun?
If nails are clogging the mechanism of your Hitachi Nail Gun, ensure you are using the specified nails. If not, use only specified nails. Also, check the magazine for issues. The driver blade might be worn, so replace it if necessary. Furthermore, the nail feeder (A) could be damaged, requiring replacement.
How to troubleshoot when my Hitachi Nail Gun cannot drive nails?
If your Hitachi Nail Gun isn't driving nails, the magazine might not be loaded with the specified genuine nails; use specified nails and remove any abnormal nails. The magazine itself might be deformed or damaged, or the nail feeder or ribbon spring could be defective; repair or replace any defective parts. Also, the nail rail could be abnormal, or there might be adhesive fragments or foreign matter present; remove any debris and apply oil to the nail feeder, ribbon spring, and nail rail. Finally, the nail inlet groove of the nose might be deformed or have adhesive fragments; repair or replace the defective part and remove any adhesive fragments.
Why does the head of a nail protrude from the wood surface when using my Hitachi NR 90AE Nail Gun?
If the head of a nail protrudes from the wood surface when using your Hitachi Nail Gun, it could be due to several reasons. First, ensure that the adjuster is properly adjusted. Second, check that the air pressure is within the range of 5 to 8.5 kgf/cm2. Also, avoid using very hard workpieces. If the issue persists, the driver blade may be worn and require replacement, or the piston O-ring might be damaged, necessitating replacement.
What to do if nails are bent when being driven with my Hitachi NR 90AE?
If your Hitachi Nail Gun is bending nails, it might be because, for short nails, the adjuster is raised too high; turn the adjuster to the lower position to decrease the pressure. Also, make sure nails are fully fed into the injection port. Other potential causes include a worn driver blade (replace it), using very hard workpieces (avoid unspecified workpieces), or a worn or damaged nail feeder (A) (replace nail feeder (A)).
Why is single actuation mechanism not possible with my Hitachi NR 90AE Nail Gun?
If your Hitachi Nail Gun's single actuation mechanism isn't working, it could be due to a worn O-ring in the plunger or valve piston, an abnormal plunger sliding surface of the valve piston, or damaged components like the plunger, trigger arm (C), pushing lever (C), or body. Replace any worn or damaged parts. Also, ensure the switching device is set to the correct position.
