Answer: (1) Before maintenance, the unit should be stopped, the exhaust valve should be closed, the power supply of the unit should be disconnected and a warning sign should be hung. The pressure in the unit should be vented (each pressure gauge should display "0") before maintenance work can be started. When removing high-temperature components, the temperature must be cooled to the ambient temperature before proceeding.
(2) Use the correct tools to repair the air compressor.
(3) It is recommended to use special oil for screw air compressors. Lubricants of different brands are not allowed to be mixed after maintenance.
(4) The original spare parts of the air compressor are specially designed and manufactured. It is recommended to use authentic spare parts to ensure the reliability and safety of the air compressor.
(5) Without the permission of the manufacturer, do not make any changes to the compressor that affect safety and reliability or add any devices.
(6) After maintenance and before starting the machine, confirm that all safety devices have been reinstalled. After the initial startup or after the electronic control system is overhauled, before starting the compressor, you must first confirm that the direction of rotation of the motor is consistent with the specified direction and that all tools have been removed from the compressor.
