The press feed line vibrates a lot when it works:
Reason:
1. The raw material is too curved.
2. The raw material is not chamfered.
3. Center dislocation.

Solution:
1. Try to buy straight materials.
2. Material tail chamfering.
3. Re-calibrate the center.

The press feed line does not alarm (backwards)/early alarm when the material is finished.
Reason:
1. The pressure is not enough.
2. The position of the material pipe is not correct.
3. Whether the motor works normally.

Solution:
1. Check the oil level.
2. Move the material tube slightly.
3. Check the wiring.
