Product Manual

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 any 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 to avoid spontaneous ignition of the oil vapour (if
applicable) 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. Protect the motor, air filter, electrical and regulating components, etc. to prevent moisture
from entering them, e.g. when steam-cleaning.
18. 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.
19. Never use caustic solvents which can damage materials of the air net, e.g. polycarbonate
bowls.
20. 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.
21. Protect hands to avoid injury from hot machine parts, e.g. during draining of oil.
22. Be aware of eventual sharp edges on certain parts of the machine.
Also consult following safety precautions: Safety precautions during installation
and
Safety precautions during operation.
