10.13.1 Venting the Machine (depressurizing)
The oil circuit vents automatically as soon as the machine is stopped.
Venting takes place in three stages:
■ Isolate the compressor from the compressed air system.
■ Vent air from the oil separator tank.
■ Vent air manually from the air cooler.
WARNING
Compressed air!
Compressed air and devices under pressure can injure or cause death if the contained energy is
released suddenly or uncontrolled.
➤ Vent all pressurized components and chambers completely.
Isolate the machine from the compressed air system
➤ Close the user's shut-off valve between the machine and the compressed air system.
If no shut-off valve is provided, the complete compressed air system must be vented.
