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 starting equipment.
7. Close the dryer air outlet valve 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 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.
17. Protect the motor, electrical and regulating components, etc. to prevent moisture from entering them,
e.g. when steam-cleaning.
18. Make sure that all sound-damping material and vibration dampers, e.g. damping material on the
bodywork, 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 desiccant:
• Take precautions not to inhale desiccant dust.
• Check that the working area is adequately ventilated; if required, use breathing protection.
• Do not overfill the dryer when replacing desiccant.
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.
