4. Venting of the cylinder lubricating system
A function control must be carried out after every assembly of the lubricating quills,
tightening lubricating oil pipes 13 and pipe brackets 21. The lubricating oil pipes
must be vented at angle union 12 and the lower union nut.
⇒
Select the respective cylinder number on context MANUAL LUBRICATION
ON CYLINDER shown on the operator interface or manually operate 4/2-way
solenoid valve 15.
⇒
Hold the position of the angle union with an open-end spanner while loosening
the lower union nut by about 1 to 2 turns.
⇒
Push with pin 17 (diameter 3.5 mm) on top of sink plunger 16 of the 4/2-way
solenoid valve. This must be repeated until the cylinder lubricating oil is flow-
ing bubble-free out of the loosened connection.
Remark: As described above the lubricating module can also be operated with the
operator interface of the control system. Further information and adjustments
about the lubricating pumps are given in the Operating Manual 7218−1.
Venting valve 20 to lubricating pump 2 may be opened by max. three turns only.

If all cylinder lubricating oil pipes are vented and afterwards properly tightened
again, actuate the cylinder lubrication module until bubble-free cylinder oil
emerges from all lubricating points in the respective cylinder liner. This visual
inspection of the lubrication process is carried out through the scavenge ports
at piston underside and the piston is therefore at T.D.C. position.
