3. The pump shaft is damaged, the rotor does not rotate, and the oil pump is repaired.
4. The suction pipe is blocked, check the suction pipe.
5. The fuel tank filter is blocked or replaced.
6. The capacity of the fuel tank filter is not enough to replace a larger capacity, which is more than twice the pump capacity.
7. The anti-wear hydraulic oil viscosity of the automatic waste paper baler is too high to replace the oil, and a heater is installed.
8. The motor speed of the automatic waste paper baler is not enough. Replace the motor speed adjusted by the oil pump.
9. The suction pipe of the oil pump is poorly sealed, and the suction pipe for gas detection.
10. The fuel tank filter is refueled on the oil level at one time or the oil level is newly designed.
