17. For water-cooled machines, the cooling water system installed outside the machine has to be protected by

a safety device with set pressure according to the maximum cooling water inlet pressure.

18. If the ground is not level or can be subject to variable inclination, consult the manufacturer.

Also consult following safety precautions:

Safety precautions during operation

and

Safety

precautions during maintenance

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.

1.4

Safety precautions during operation

All responsibility for any damage or injury resulting from neglecting these precautions, or
non observance of the normal caution and care required for installation, operation,
maintenance and repair, even if not expressly stated, will be disclaimed by the
manufacturer.

Precautions during operation

1. Never touch any piping or components of the compressor during operation.
2. Use only the correct type and size of hose end fittings and connections. When blowing through a hose or

air line, ensure that the open end is held securely. A free end will whip and may cause injury. Make sure
that a hose is fully depressurized before disconnecting it.

3. 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.

4. Never operate the machine when there is a possibility of taking in flammable or toxic fumes, vapors or

particles.

5. Never operate the machine below or in excess of its limit ratings.
6. Keep all bodywork doors shut during operation. The doors may be opened for short periods only, e.g. to

carry out routine checks. Wear ear protectors when opening a door.
On compressors without bodywork, wear ear protection in the vicinity of the machine.

7. People staying in environments or rooms where the sound pressure level reaches or exceeds 80 dB(A)

shall wear ear protectors.

8. Periodically check that:

• All guards are in place and securely fastened
• All hoses and/or pipes inside the machine are in good condition, secure and not rubbing
• No leaks occur
• All fasteners are tight
• All electrical leads are secure and in good order
• Safety valves and other pressure relief devices are not obstructed by dirt or paint
• Air outlet valve and air net, i.e. pipes, couplings, manifolds, valves, hoses, etc. are in good repair, free

of wear or abuse

• Air cooling filters of the electrical cabinet are not clogged

9. If warm cooling air from compressors is used in air heating systems, e.g. to warm up a workroom, take

precautions against air pollution and possible contamination of the breathing air.

10. On water-cooled compressors using open circuit cooling towers, protective measures must be taken to

avoid the growth of harmful bacteria such as Legionella pneumophila bacteria.
