➤ 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 foodstuffs.
➤
Use foodstuff-compatible cooling oil whenever compressed air is to come into contact with
foodstuffs.
Spring force
Springs under tension or compression store energy. Uncontrolled release of this force 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 access doors and cover panels while the machine is running.
➤ Switch off and lock out the machine and check that no voltage is present before opening the
access doors or canopy.
➤ 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
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, for example, engine, compressor airend, oil and compressed air lines, coolers
and oil separator 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 compressed air hoses.
➤ Allow the machine to cool down before commencing any maintenance work.
➤ When welding is taking place on or near the machine take adequate measures to ensure that
no parts of the machine or any oil vapours can ignite because of sparks or heat.
Noise
The enclosure absorbs the machine noise to a tolerable level. This function will be effective only if
the bodywork is closed.
➤ Operate the machine only with closed bodywork and intact sound insulation.
➤ Wear hearing protection if necessary.
The pressure relief valve blowing off can be particularly loud.
Operating fluids/materials
The used operating fluids and materials can cause adverse health effects. Suitable safety meas‐
ures must be taken in order to prevent injuries.
➤ Strictly forbid fire, open flame and smoking.
