Most PFAFF machines are self-lubricating machines and do not require additional lubrication (with the exception of the PowerQuilter p3, powerquilter 16.0, GrandQuilter 18.8 and GrandQuilter.
In addition to these, the select 4.2 requires oiling by the consumer as does the SMARTER BY PFAFF C1100 Pro).  We recommend taking your PFAFF machine to your local authorized PFAFF  dealer once a year for a cleaning and tune up.
