1. Open the reservoir on the vacuum oil-filling machine and pour in the oil;
2. Secure the reservoir cap and switch on the vacuum pump to begin evacuation;
3. Once the vacuum pump has evacuated the air to the required level, turn off the pump and open the oil-filling valve;
4. With the valve open, the oil will automatically flow into the machine until it overflows from the filling port;
5. Close the oil-filling valve and disconnect the filling hose to complete the process.
Refilling oil in this manner not only ensures effective lubrication and prevents the adverse effects of overfilling on the machine, but also reduces the manual workload and improves operational efficiency.
