3. Piston Assembly: This component drives the nails into the material and is powered by compressed air.

4. Trigger Assembly: The trigger controls the firing mechanism of the nailer.

5. Air Inlet: This is where the compressed air source is connected to power the nailer.

6. Depth Adjustment: Hitachi nailers often have a depth adjustment feature that allows you to control the depth to which nails are driven.
