There are many reasons for rivet gun failures, and we need to choose appropriate methods to solve them based on different situations.

1. Replace the spring of the gun head, clean the impurities in the middle of the three claws, and then discharge all the water vapor in the water vapor separator and air compression pump.

2. The power of the rivet gun decreases, check if the air pressure is within the specified range, otherwise the parts need to be replaced. When replacing, ensure that the gap between the parts is maintained at 0.015 to 0.3 millimeters.

3. The rivet gun piston or movable valve is stuck, and it needs to be cleaned or the rough edges repaired at this time.

4. The rivet gun lubrication is abnormal and needs to be cleaned.

5. The air consumption of the rivet gun has increased, and it is necessary to replace the movable valve, abnormal air block, or punch.

6. If the rivet gun components fail, replace the O-ring or valve stem, but the specific response method depends on the type of rivet gun.

7. The rivet gun cylinder head is leaking. Open the cover and check the flat washer and outer ring of the cylinder head to ensure that there are no aluminum scratches or sand holes on the inner ring.
