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 (fresh air reinforcement) and/or for the processing of comestibles.
➤ Use comestibles-compatible cooling oil whenever compressed air is to come into contact with
comestibles.
Spring forces
Springs under tension or compression store energy. Uncontrolled release of this energy can cause
serious injury or death.
Minimum pressure check valves, safety 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 service doors or panels while the machine is running.
➤ Prior to opening the service doors or the enclosure, switch off the engine, disconnect from
power source and secure against unintended reactivation.
➤ Wear close-fitting clothes and a hair net if necessary.
➤ Ensure that all covers and safety guards are in place and secured before re-starting.
Temperature
The operation of the combustion engine and the compression generate high temperatures. Touch‐
ing hot components may cause injuries.
➤ Avoid contact with hot components.
These include combustion engine, airend, oil and compressed air lines, coolers and oil separa‐
tor tank. Any objects in or near the flow of exhaust gas or discharged cooling air will become
very hot.
➤ Wear protective clothing.
➤ Wear protective gloves when connecting or disconnecting external compressed air hoses to
the outlet valves.
➤ Allow the machine to cool down before commencing any maintenance work.
➤ 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 body is closed.
➤ Operate the machine only with closed body.
➤ Check machines that are lined with sound insulation material for perfect condition of the sound
insulation material.
➤ Wear ear protection if necessary.
Safety valve blow-off results in high noise emission.
➤ Never generate compressed air without consumers being connected.
