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 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 or 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.
➤ Ensure that all covers and safety guards are in place and secured before restarting.
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.
➤ If welding is carried out on or near the machine, take adequate measures to prevent sparks or
heat from igniting oil vapors or parts of the machine.
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 blowing-off of the safety relief valve can be particularly loud.
➤ Never generate compressed air without air consumers being connected.
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.
➤ Follow safety regulations when dealing with fuel, lubricants, antifreeze, and chemical substan‐
ces.
➤ Avoid contact with skin and eyes.
➤ Do not inhale fumes or vapors from fuel or oil.
