10. Scrupulously observe cleanliness during maintenance and repair. Keep dirt away by covering the
parts and exposed openings with a clean cloth, paper or tape.
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 vapor 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 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. Only if applicable, the following safety precautions are stressed when handling refrigerant:
• Never inhale refrigerant vapors. 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.
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.
