NOTICE
Risk of damage to property!
The operation of the rotary modules with oil-lubricated compressed air causes
the factory primary lubrication to be washed out. Therefore, it is absolutely
essential that the rotary modules continue to be operated with oil-lubricated
compressed air in order to avoid damage to the rotary modules.
Once the rotary modules have been operated with oil-lubricated
compressed air, they
may never
be operated without oil-lubricated
compressed air.
