2. Jamming or Misfeeding:

• Solution:

• Unload the nail magazine and visually inspect for any jammed nails. Remove any obstructions or damaged nails.
• Examine the magazine spring and pusher to ensure they’re functioning correctly. Replace them if needed.
• Lubricate the magazine and firing mechanism with brad nailer oil to prevent future jams.

3. Worn or Damaged Parts:

• Solution:

• Inspect the O-rings, seals, and gaskets for signs of wear or damage. These components play a crucial role in maintaining air pressure and proper firing. Replace any worn parts.
• Check the condition of the driver blade and replace it if it’s bent or damaged.

4. Regular Maintenance:
