In this guide, we will provide a concise overview of the key parts and their functions.

1. Nosepiece:

3. Magazine:
4. The magazine is where nails are loaded for firing. It typically holds a strip of nails and features a follower that pushes nails into the nosepiece as they are used.

5. Trigger and Safety Mechanism:
6. The trigger controls the nail gun’s firing. The safety mechanism prevents accidental discharges. Familiarize yourself with their operation to ensure safe and controlled firing.

7. Air Inlet:
