In addition, for cutting ring unions:
After tightening the cutting ring union, a visible gap must
remain between the union nut and the adaptor fitting. This
gap becomes smaller every time the cutting ring union is
loosened and tightened again. If a gap is no longer visible
during tightening of the cutting ring union, the union can no
longer be sufficiently tightened and will leak. The cutting ring
union and the pipeline must then be replaced.
After completion of all maintenance work:
n Remove "Attention! Maintenance work!" sign.
n T
urn on the power supply to the Sauer-Compressor.
n Perform an inspection 50 operating hours after all maintenance work.
Check all screws affected by maintenance work to see if they are tight.
