In order to ensure the normal operation and long service life of the unit, good maintenance is the key. Therefore, the maintenance procedures of the screw air compressor unit must be carefully implemented. Before starting maintenance, make at least the following preparations:
1. Cut off the power supply to the host and hang a sign on the power switch.
2. Close the stop valve to the air supply system to prevent the compressed air from flowing back to the repaired part. Never rely on a check valve to isolate the air supply system;
3. Open the manual vent valve to drain the pressure in the system and keep the vent valve in the open state;
4. For water-cooled machines, water supply system must be closed to release the pressure of water pipes;
5. Ensure that the screw air compressor has been cooled to prevent burns and burns;
6. Wipe oil and water marks on the ground to prevent slipping.
