NOTICE
Lubricating a dry running machine (compression chamber).
Risk of damage to the machine!
• Do not lubricate the compression chamber of the machine with oil or grease.
• Make sure that the installation conditions (see Installation Conditions [►7]) are met.
• Switch on the machine.
• Make sure that the maximum permissible number of starts does not exceed 6 starts
per hour. Those starts should be spread within the hour.
• Make sure that the operating conditions comply with the Technical Data [►22].
• After a few minutes of operation, perform an Oil Level Inspection [►15].
As soon as the machine is operated under normal operating conditions:
• Measure the motor current and record it as reference for future maintenance and
troubleshooting work.
6.1 Compression Chamber Flushing
Depending on the process type (very demanding application), flushing through the com-
pression chamber (cylinder + lobes) might need to be performed. Seek advice from your

Flushing without barrier gas.
Risk of damage to the machine!
• The flushing process can pass over into the bearings and the oil chambers!
Do not perform flushing without using the barrier gas.
