8 Maintenance
8.1 Preventive maintenance schedule
Warning
Always apply all relevant Safety precautions.
Before carrying out any maintenance, repair work or adjustments, proceed as
follows:
• Stop the compressor.
• Close the air outlet valve and open the manual drain valve until the air system
between air receiver and outlet valve is fully depressurized.
• Press the emergency stop button.
• Switch off the voltage. Open and lock the isolating switch.
• Depressurize the compressor by opening the oil filler plug one turn.
Only pressing the emergency stop button is not sufficient to make the compressor
voltage free.
If the machine is equipped with an automatic restart after voltage failure function and if
this function is active, be aware that the machine will restart automatically when the
power is restored if it was running when the power was interrupted.
