As to ensure normal operation of the unit and to have longer service life,good maintenance is the key. Therefore,we must seriously implement the maintenance procedures of the screw air compressor.Before embarking on maintenance,we should prepare at least for the following:

1.Cut off the host power supply and  put up the sign near the power switch;

2.Close the stop valve to the air supply system in case of the compressed air flowing back to the part overhauled.Never rely on check valve to isolate the air supply system.

3.Open the manual venting valve，emptying the pressure inside the system,and keep the venting valve   open;

4.As to the water cooling machine, we must turn off the water supply system and release the pressure of the water;

5.Make sure the screw air compressor units has cooled to prevent empyrosis and burns;

6.Wipe the grease marks, water stains to prevent slippery.
