   Solution:
2. Disconnect the power source (remove the battery or unplug the air hose).
3. Open the nail gun’s magazine and carefully remove any jammed nails.
4. Examine the nails you’re using; they should be the right size and gauge for your nail gun.

   Solution:
7. First, check that the power source is connected and working correctly.
