Common faults of foot cutter
<1> Short circuit phenomenon: the material is located on the plug-in head, when the START button is pressed, the plug-in head will go down and come up again, but the machine will not move. The detection circuit causes the detection circuit to be in a closed state, which has caused the machine to fail to work normally.
Causes of short circuit:
(1) The distance between the fixed knife and the insulated pin is too small, causing contact between the fixed knife and the insulated pin, causing a short circuit
Solution: Adjust the gap between the fixed knife and the insulating pin to be 2-3 thousandths of an inch
(2) The elastic top wire of the foot clipper is too short or loses elasticity: The elastic top wire of the foot clipper is too short or loses elasticity, and cannot lift the fixed knife, causing contact between the fixed knife and the insulation pin. Even if the fixed knife and the insulation pin are not in contact at first, after completing a foot shearing action, it will still make contact between the fixed knife and the insulation pin, and the elastic top wire cannot lift the fixed knife, causing it to be in contact with the insulation pin, causing a short circuit
Solution: First, determine whether the elastic top wire is elastic or too short. If the elastic top wire loses elasticity, replace it; If the elastic top screw is too short, tighten it to the end with a wrench and then reverse it by 3/4 turns (i.e. 270 degrees)
(3) The insulation layer of the insulation pin is damaged: The insulation layer of the insulation pin is damaged, causing its conductive part to come into contact with the foot clipper body, even if it comes into contact with the fixed knife, causing the detection circuit to remain closed for a long time, resulting in a short circuit
Solution: Replace the insulation pin. If it is not visible to the naked eye whether the insulation pin is worn, remove the two detection wires and use an electric meter on the machine to measure whether there is continuity between the insulation pin and the foot clipper body. If there is continuity, it indicates that the insulation is worn and broken, and replacement is sufficient
(4) The detection line is damaged and comes into contact with the foot clipper body, causing the detection line to remain closed for a long time, resulting in a short circuit
Solution: Wrap the damaged area with insulating tape and prevent it from coming into contact with the foot clipper body or replace the detection wire
(5) The connection between the detection line on the base and the base is conductive, which also means that the entire line is in a closed state, causing a short circuit
Solution: Use a multimeter to measure whether there is continuity between the base and the joint. If necessary, replace the joint
(6) The two detection wires located under the base are short circuited, which is equivalent to the entire circuit being closed, causing a short circuit
Solution: Use a multimeter to measure whether the voltage between two detection wires is 12V. If it is not and 0, it indicates that a short circuit has occurred. Replace the detection wire
(7) There is a problem with the detection circuit at the end of the machine, such as a short circuit or something else Solution: This type of situation has not been encountered yet, and we cannot provide a specific solution here. Please feel free to give us your advice
