3. Use only genuine spare parts for maintenance or repair. The manufacturer will disclaim all
damage or injuries caused by the use of non-genuine spare parts.
4. All maintenance work shall only be undertaken when the machine has cooled down.
5. A warning sign bearing a legend such as "Work in progress; do not start" shall be attached
to the starting equipment.
6. Persons switching on remotely controlled machines shall take adequate precautions to
ensure that there is no one checking or working on the machine. To this end, a suitable
notice shall be affixed to the remote start equipment.
7. Close the compressor air outlet valve and depressurize the compressor before connecting
or disconnecting a pipe.
8. Before removing any pressurized component, effectively isolate the machine from all
sources of pressure and relieve the entire system of pressure.
9. Never use flammable solvents or carbon tetrachloride for cleaning parts. Take safety
precautions against toxic vapors of cleaning liquids.
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.
