Why does the head of a nail protrude from the wood surface when using my Hitachi NR 83A2?
- Z
  Zachary BautistaJul 27, 2025
  If the head of a nail driven into a workpiece protrudes from the wood surface when using your Hitachi Power Tool, the adjuster might be improperly adjusted, so adjust it to the proper position. Also, the air pressure could be too low; adjust it for 5 to 8.5 kgf/cm2. A worn driver blade or abnormal piston ring (worn or damaged) can also cause this issue, so replace the defective part.

What to do if nails are bent when being driven with my Hitachi NR 83A2 Power Tool?

  If nails are bending when driven by your Hitachi Power Tool, it could be due to several reasons. If using short nails, the adjuster may be raised too high; turn the adjuster to a lower position to decrease the pressure. Also, make sure the nails are fully fed into the injection port (refer to item 1). A worn driver blade can also cause bending, so replace it. Finally, the workpiece may be too hard; avoid using unspecified workpieces.

  If nails cannot be driven with your Hitachi Power Tool, ensure that the magazine is loaded with specified genuine nails. Remove any abnormal nails and load the magazine with normal nails. Check the nail groove of the magazine for abnormalities (too wide, too narrow, deformed, or damaged); repair or replace the defective part, remove any adhesive fragments, and apply oil to the nail feeder, ribbon spring, and the nail rail. Also, inspect the nail inlet groove of the nose for abnormalities (deformed, burrs, or damaged); repair or replace the defective part and remove any adhesive fragments.

Why does the piston actuate just by pulling the trigger on my Hitachi NR 83A2?
- D
  David GlassAug 16, 2025
  If the piston actuates just by pulling the trigger (when single actuation is selected) on your Hitachi Power Tool, the O-ring (inside dia. 10.7) at the outside of the valve bushing may be abnormal (worn, damaged, or broken). Replace the defective part. Additionally, the gasket (G) may be abnormal (improperly mounted, worn, or damaged); mount it properly or replace the defective part.
