1. Slow clamping action or insufficient clamping stroke of the coil nailer: the bolt is loose, the inner plate of the front buckle trigger is worn. At this time, you can tighten the bolt, paying attention to the correct position of the front buckle. You can also replace the front buckle or the inner plate of the trigger. After completing the above actions, test its function, if the stroke is too short, fine-tune the front buckle shaft upward, if the movement is slow, fine-tune the front buckle shaft downward;

 

2. The exhaust port air leakage: switch valve ring or switch seat ring damaged or piston ring damaged. Replace the ring.

 

3. Air leakage at the piston rod: the bottom ring of the main body is damaged. The ring should be replaced.

 

4. Air leakage at trigger: switch valve ring or switch seat ring is damaged. Replace the ring.

 

5. The transmission ring is loose and cannot be located: plastic steel bars and transmission springs are inelastic. Remove the trigger assembly, and reinstall the spring tip or replace the plastic steel bar and transmission spring.
