Quantity of Lubrication Oil
When the Rotary blades vacuum pump is running, check that the quantity of oil indicated in Table 4 is dripping from the
special regulator tap. These quantities are valid for both Forced and Automatic Lubrication. When necessary, add only
unused clean oil to the tank.
PTO Versions: make the first oil change in the gearbox after approx. 100 working hours and subsequent changes
approx. every 300 working hours.
Adjusting the Lubricating Oil
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 any reason, a different setting is required proceed as follows: remove pin cover “B” (see
Figure 9), loosen lock nut “C” and then turn regulator pin “A”. 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.
