NOTE
It is important that the oil level stays within the range MIN and MAX that is
indicated by the level gauge on the side of the pump.
Carry out the first filling up through the plug (E) up to the half of the
sight glass (F) and close the plug (E) (see following figure).
Figure 12
Start the pump and take it to the maximum vacuum level for at least
2 minutes. Stop the pump, check again the oil level and add the
lacking oil, if necessary, in order to get the correct oil level.
Tips for using
When the room temperature is lower than 18°C, it is a good practice
to let the pump operate at the ultimate pressure (Inlet port closed,
without load) for about 15 minutes..
During this period the pump may not reach the stated pressure
limits.
