3 Safety and Responsibility
3.5 Dangers
➤ De-pressurise all pressurised components and enclosures.
➤ Do not carry out welding, heat treatment or mechanical modifications on pressurised compo‐
nents (e.g. pipes and vessels) as this influences the component's resistance to pressure.
The safety of the machine is then no longer ensured.
Compressed air quality
The composition of the compressed air must be suitable for the actual application in order to pre‐
clude health and life-threatening dangers.
➤ Use appropriate systems for air treatment before using the compressed air from this machine
as breathing air and/or for the processing of foodstuffs.
➤ Use foodstuff-compatible cooling oil whenever compressed air is to come into contact with
foodstuffs.
Spring forces
Springs under tension or compression store energy. Uncontrolled release of this energy can cause
serious injury or death.
Minimum pressure / check valves, pressure relief valves and inlet valves are powerfully spring-loa‐
ded.
➤ Do not open or dismantle any valves.
Rotating components
Touching the fan wheel, the coupling or the belt drive while the machine is switched on can result
in serious injury.
➤ Do not open the enclosure while the machine is activated.
➤ Switch off and lock out the power supply disconnecting device and verify the absence of any
voltage.
➤ Wear close-fitting clothes and a hair net if necessary.
➤ Make sure all covers and safety guards are in place and secured before re-starting.
Temperature
High temperatures are generated during compression. Touching hot components may cause inju‐
ries.
➤ Avoid contact with hot components.
These include, for example, compressor airends or blocks, oil and compressed air lines, cool‐
ers, oil separator tanks, motors and machine heaters.
➤ Wear protective clothing.
➤ If welding is carried out on or near the machine, take adequate measures to prevent sparks or
heat from igniting oil vapours or parts of the machine.
Noise
The enclosure absorbs the machine noise to a tolerable level. This function will be effective only if
the enclosure is closed.
➤ Operate the machine only with intact sound insulation.
➤ Wear hearing protection if necessary.
The blowing-off of the pressure relief valve can be particularly loud.
