The operator has to make sure that the machine is stopped and that the isolating switch is open and locked before any
maintenance or repair. As a further safeguard, 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 start equipment.
10.
Air-cooled machines must be installed in such a way that an adequate flow of cooling air is available and that the
exhausted air does not re-circulate to the compressor air inlet or cooling air inlet.
11.
The electrical connections must correspond to the applicable codes. The machines must be earthed and protected
against short circuits by fuses in all phases. A lockable power isolating switch must be installed near the compressor.
12.
On machines with automatic start-stop system or if the automatic restart function after voltage failure is activated, a sign
stating "This machine may start without warning" must be affixed near the instrument panel.
13.
In multiple compressor systems, manual valves must be installed to isolate each compressor. Non-return valves (check
valves) must not be relied upon for isolating pressure systems.
14.
Never remove or tamper with the safety devices, guards or insulation fitted on the machine. Every pressure vessel or
auxiliary installed outside the machine to contain air above atmospheric pressure must be protected by a pressure-
relieving device or devices as required.
15.
Pipework or other parts with a temperature in excess of 80°C (176°F) and which may be accidentally touched by
personnel in normal operation must be guarded or insulated. Other high-temperature pipework must be clearly marked.
16.
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.
17.
If the ground is not level or can be subject to variable inclination, consult the manufacturer.
4.2. Safety precautions during operation
General precautions
1.
The operator must employ safe working practices and observe all related work safety requirements and regulations.
2.
If any of the following statements does not comply with the applicable legislation, the stricter of the two shall apply.
3.
Installation, operation, maintenance and repair work must only be performed by authorised, trained, specialised
personnel.
4.
The compressor is not considered capable of producing air of breathing quality. For air of breathing quality, the
compressed air must be adequately purified according to the applicable legislation and standards.
5.
Before any maintenance, repair work, adjustment or any other non-routine checks, stop the compressor, press the
emergency stop button, switch off the voltage and depressurise the compressor. In addition, the power isolating switch
must be opened and locked.
6.
Never play with compressed air. Do not apply the air to your skin or direct an air stream at people. Never use the air to
clean dirt from your clothes. When using the air to clean equipment, do so with extreme caution and wear eye
protection.
Precautions during operation
1.
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.
2.
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.
3.
Never operate the machine when there is a possibility of taking in flammable or toxic fumes, vapours or particles.
4.
Never operate the machine below or in excess of its limit ratings.
5.
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.
6.
People staying in environments or rooms where the sound pressure level reaches or exceeds 90 dB(A) shall wear ear
protectors.
7.
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
•
There are no leaks
•
All fasteners are tight
