c) Main pump flow: 10 L/min (2.64 gal/min).

d) Working media: N46 hydraulic oils.

e) Oil cleanliness: NAS1683 standard 11 to 12 grade.

3.3.2 Special elements and adjustment parameters

a) Hydraulic system pressure adjustment: hydraulic system pressure was established by variable

piston pump bolt in the system.

b) System pressure adjustment: Clockwise adjustment vane pump PVF-12 regulator handle or

regulator bolt. At this time the pressure gauge will rise slowly until the pressure gauge pointer to

3MPa, lock the locking nut. These are hydraulic station conditions when the machine is under

working, the other actions do not affect above adjustment.

c) Hydraulic system flow adjustment: Hydraulic system flow was established by the vane pump

screw in the system.

d) Adjust the system flow: Clockwise adjustment vane pump PVF-12 flow adjustment bolt handle.

At this point the flow becomes smaller, counter-clockwise adjustment, flow increases; it will be

fully flow when completely open.
