Before starting the electric compressor, check that the airend is rotating correctly. Monitor the oil level daily and drain water from the drain glass regularly. Check electrical connections weekly and test the safety valve. Perform more thorough maintenance every 250 hours by checking the oil and air filters, and change the filters if needed every 500 hours. Conduct an oil analysis at 1000 hours and change filters if not already done at 500 hours, in addition to lubricating the electric motor.
