1. If the cylinder fails to work when the circuit is good, please check if the muffler throttle valve is completely checked so as no air can be exhausted. If yes, please readjust the valve. If not, please check if there is disconnection of electromagnetic valve loop by multimeter. If there is no disconnection, the result may be damage in electromagnetic valve, please replace it.
2. If the cylinder is not in a constant speed, it may caused by excessively low air pressure or leakage of the obstructing ring.
3. The iconicity of workpiece after turning may due to loosening of V-shape clamp or wrong position of the leading rail of the V-shape clamp.
4. If the rotor fails to rotate, it may caused by the two reasons. The loose belt of the main motor is loose. Or the contact angle of rotor belt is too small.
