6.6 LUBRICATION OIL ADJUSTMENT
To adjust the dripping of oil in the Rotary blades vacuum pump with forced lubrication, turn the regulator ring nut "A" (see Figure
8) after loosening ring nut "B".
Tighten ring nut "B" again when adjustment has been completed.
The adjustment of oil delivery, in automatic lubrication, is carried out at our factory during final testing of the Rotary blades vacuum
pump.
If for a particular reason a different setting is required, proceed as follows: remove the pin cover (see Figure 9), loosen the nut "C"
and then act on the "A" adjustment pin.
By rotating clockwise lower oil delivery is obtained (-), and by rotating anticlockwise higher oil delivery is obtained (+). When
adjustment has been completed tighten lock nut "C" and screw cover.
