11. Never weld or perform any operation involving heat near the oil system. Oil tanks must be completely
purged, e.g. by steam-cleaning, before carrying out such operations. Never weld on, or in any way modify,
pressure vessels.
12. Whenever there is an indication or any suspicion that an internal part of a machine is overheated, the
machine shall be stopped but no inspection covers shall be opened before sufficient cooling time has
elapsed; this to avoid the risk of spontaneous ignition of the oil vapour when air is admitted.
13. Never use a light source with open flame for inspecting the interior of a machine, pressure vessel, etc.
14. Make sure that no tools, loose parts or rags are left in or on the machine.
15. All regulating and safety devices shall be maintained with due care to ensure that they function properly.
They may not be put out of action.
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, e.g. 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.
Also consult following safety precautions: Safety precautions during installation and Safety
precautions during operation.
These precautions apply to machinery processing or consuming air or inert gas. Processing
of any other gas requires additional safety precautions typical to the application which are not
included herein.
Some precautions are general and cover several machine types and equipment; hence some
statements may not apply to your machine.
