➤ Do not carry out welding, heat treatment or mechanical modifications to pressurized components
(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
➤ Never directly inhale compressed air.
➤ 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 food‐
stuffs.
Spring tension
Springs under tension or compression represent contained energy. Uncontrolled release of this en‐
ergy can cause serious injury or death.
Minimum pressure/check valves, pressure relief valves and inlet valves are powerfully spring-loaded.
➤ 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 switched on.
➤ Switch off and lock out the power supply disconnecting device and check that no voltage is
present.
➤ Wear close-fitting clothes and a hair net if necessary.
➤ Make sure all covers and safety guards are in place and secured before starting.
Temperature
➤ Avoid contact with hot components.
These include, for example, compressor airends or blocks, oil and compressed air lines, coolers,
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
➤ Operate the machine only with full soundproofing.
➤ Wear hearing protection if necessary.
The pressure relief valve blowing off can be particularly loud.
Operating materials
➤ Strictly forbid fire, open flame and smoking.
➤ Follow safety regulations when dealing with lubricants and chemical substances.
➤ Avoid contact with skin and eyes.
➤ Do not inhale oil mist or vapour.
➤ Do not eat or drink while handling cooling and lubricating fluids.
