If no shut-off valve is provided, the complete gas network must be vented.
Vent the oil separator tank.
The oil circulation vents automatically as soon as the machine is stopped.
➤ Check that the oil separator tank pressure gauge reads 0 bar.
After automatic venting the pressure gauge does not read 0 bar?
➤ Make sure that the shut-off valve is closed or that the complete gas network is vented.
➤ With the shut-off valve closed, insert the male hose fitting

Replenishing the cooling oil
A sticker on the oil separator tank specifies the type of oil used.
1. WARNING!
Compressed gas!
Compressed gas and devices under gas pressure can injure or cause death if the contained
energy of the gas is released suddenly or uncontrolled.
➤ Vent all pressurized components and chambers completely.
2. NOTICE!
The machine could be damaged by unsuitable oil.
➤ Never mix different types of oil.
➤ Never top up with a different type of oil to that already used in the machine.
3. Slowly unscrew the filler plug
