Extending or modifying the compressor station
If dimensioned appropriately, safety relief valves reliably prevent an impermissible rise in pressure.
New dangers may arise if you modify or extend the compressed air station.
➤ When extending or modifying the compressed air system:
Check the blow-off capacity of safety relief valves on air receivers and compressed air lines
before installing a new machine.
➤ If the blow-off capacity is insufficient:
Install safety relief valves with larger blow-off capacity.
3.5.2 Safe machine operation
The following is information supporting you in the safe handling of the machine during individual
product life phases.
Personal protective equipment
When working on the machine you may be exposed to dangers that can result in accidents with
severe adverse health effects.
➤ Wear protective clothing as necessary.
Suitable protective clothing (examples):
■ Safety workwear
■ Protective gloves
■ Safety boots
■ Eye protection
■ Ear protection
Transporting
The weight and size of the machine require safety measures during its transport to prevent acci‐
dents.
➤ Use suitable lifting gear that conforms to local safety regulations.
➤ Allow transportation only by personnel trained in the safe movement of loads.
➤ Attach lifting gear only to suitable lifting points.
➤ Be aware of the center of gravity to avoid tipping.
➤ Make sure the danger zone is clear of personnel.
➤ Do not step onto machine components to climb up the machine.
Assembly
➤ Only use only electrical cables that are suitable and approved for the surroundings and electri‐
cal loads applied.
➤ Never dismantle compressed air pipes until they are fully vented.
➤ Only use pressure lines that are suitable and approved for the maximum working pressure and
the intended medium.
➤ Do not allow connection pipes to be placed under mechanical stress.
➤ Do not induce any forces into the machine via the connections, so that the compressive forces
must be balanced by bracing.
