Terms of Use 1. The nail clamping action of the sealing machine is too slow or the nail clamping stroke is insufficient: the bolt is loose, the front buckle or the inner plate of the trigger is worn. At this time, the bolt can be tightened, paying attention to the correct position of the front buckle shaft. You can also replace the front buckle or the trigger inner film. After completing the above actions, test its function. If the stroke is too short, fine-tune the front buckle shaft upwards, and fine-tune the front buckle shaft downward if the movement is slow; 2. Air leakage at the piston rod: the bottom ring of the main body is damaged. The ring should be replaced at this time. 3. Air leakage at the exhaust port: the switch valve ring or switch seat ring is damaged or the piston ring is damaged. Replace the ring. 4. Air leakage at the trigger: the switch valve ring or switch seat ring is damaged. Replace the ring. 5. The transmission ring is loose and cannot be positioned: the plastic steel strip and the transmission spring are inelastic. Remove the trigger assembly and reinstall the spring pin or replace the plastic steel bar and drive spring
