Never mix different types of oil.

Close the user’s shut---off valve between the machine and the air main.
If no shut---off valve is provided, the complete air system must be vented.
The hose coupling, shut---off valve and maintenance hose lie beneath the
oil separator tank.

Check that the oil separator tank pressure gauge (2) reads zero.
After automatic venting the pressure gauge does not read zero?
Make sure that the shut---off valve is closed.
If manual venting does not bring the oil separator tank pressure gauge
to zero, call KAESER service.
Manually venting the oil separator tank
With the shut---off valve closed, insert the male hose fitting (6) into the hose coupl-
ing (3).
Open the shut---off valve (7) slowly to release pressure.
Withdraw the male hose fitting and close the shut---off valve.
