Proceed as follows to connect the scavenging holes:
1. Remove the protective plugs of the scavenging gas holes on the
motor.
2. Fasten the scavenging lines in the appropriate connection threads on
the motor.
When connecting the scavenging lines, pay attention to the correct
flow direction.
3. Tighten the connection firm.
Only inert gas or cleaned and dried industrial air is permitted to be used
as scavenging gas. In any case, a filter must be installed upstream if the
quality in terms of foreign particles cannot be ensured.
