9.
Switch off the system as soon as the oil level reaches the
mark
in the hydraulic tank. Move the
cylinder into the marked initial position and top it off with
oil up to 2/3 full.
If necessary, repeat the step several times until the whole
hydraulic system is filled with sufficient oil.
10. Once the hydraulic system has been filled and adequately bled of air,
close the breather fitting (B.22) on the unit.
Remove the hoses that were attached for the filling procedure, move
the selector valve (4.7) on the valve block to position (a) and start the
OLF 5 bypass flow fluid filtration unit (2.1).
11. To bleed the OLF 5 bypass flow filtration unit (2.1), mount a 1602
measurement hose to the gauge port (2.7) on the cover of the OLF 5
bypass flow filtration unit (2.1).
Insert the other end into the unpressurized external oil container.
Switch the filtration unit (2.1) on. If oil escapes at the open hose end
but no air or air bubbles, unscrew the measurement hose and switch
the OLF 5 bypass flow filtration unit (2.1) off.
12. The free air trapped in the hydraulic tank will be suctioned off at the
start with the aid of the degassing unit. This will cause the oil level in
the hydraulic tank to rise. Depending on the size of the hydraulic tank
and its design and geometry, the suctioning off of the free air will take
≈ 1 hour or longer.
Once the free air has been removed, the degassing of the air that is
dissolved in the oil begins. The diaphragm is now completely up
against the walls of the diaphragm cage. The pressure displayed on
the pressure sensor then drops below the 500 mbar limit.
13. Slowly increase the nominal flow and the system pressure up to the
required operating conditions.
Note that the oil level in the fluid level indicator (7.24) must be within
the markings
