16. Before clearing the machine for use after maintenance or overhaul, check that operating pressures, temperatures and
time settings are correct. Check that all control and shut-down devices are fitted and that they function correctly. If
removed, check that the coupling guard of the compressor drive shaft has been reinstalled.
17. Every time the separator element is renewed, examine the discharge pipe and the inside of the oil separator vessel for
carbon deposits; if excessive, the deposits should be removed.
18. Protect the motor, air filter, electrical and regulating components, etc. to prevent moisture from entering them, e.g.
when steam-cleaning.
19. Make sure that all sound-damping material and vibration dampers, e.g. damping material on the bodywork and in the
air inlet and outlet systems of the compressor, is in good condition. If damaged, replace it by genuine material from the
manufacturer to prevent the sound pressure level from increasing.
20. Never use caustic solvents which can damage materials of the air net, e.g. polycarbonate bowls.
21. The following safety precautions are stressed when handling refrigerant:
• Never inhale refrigerant vapours. Check that the working area is adequately ventilated; if required, use breathing
protection.
• Always wear special gloves. In case of refrigerant contact with the skin, rinse the skin with water. If liquid refrigerant
contacts the skin through clothing, never tear off or remove the latter; flush abundantly with fresh water over the
clothing until all refrigerant is flushed away; then seek medical first aid.
22. Protect hands to avoid injury from hot machine parts, e.g. during draining of oil.
