If the foot pedal fails on the high-speed overlock machine model, the maintenance personnel can check and troubleshoot the fault through the following inspections: 1. Check the machine head/system problems. 2. After eliminating the machine head/system problem, the problem cannot be solved. At this time, check whether the tight ring of the pneumatic switch on the pedal connecting rod is loose.
Adjust the up and down positions of 1, 3 to ensure that switches 4 and 5 can work normally when stepping on and down the pedal; adjust the upper and lower positions of 2 to make the spring pressure moderate to ensure that switches 4 and 5 work normally.
