1. Identify the Source of Air Leakage:

Air leakage can occur for several reasons. Before attempting any fixes, it’s crucial to determine where the leakage is coming from. Common sources include:

• Hose Connection: Check the connection between the nail gun and the air hose for any visible damage or loose fittings.
