4.2.2 BLEEDING PROCEDURE
The S800H operator kit comes with a field installable hydraulic
manual release, that can be conveniently mounted on top of
the load bearing box
1. Manually release the operator and make sure it is turned off
with the batteries disconnected
2. Remove the vent screws from each flange
3. Spin the set nut all the way onto the union bolt (Fig. 18)
4.Tighten the union bolt into the flange by hand and then snug
it down with a 13mm wrench to 20 Nm. This will set the flare of
the union bolt into the flare of the flange.
Do not overtighten the
union bolt as it can permanently damage the flange
5. Next with a wrench still on the union bolt, spin the set nut down
by hand and then snug it down to 20 Nm. Reference Fig. 20 for
the correct visual of the installed union bolt with set nut.
6. Continue installing the hoses and banjo bolts and then bleed
the system as shown in section 4.2.2. Inspect for leaks, if you find
any repeat the above steps.
7. Fasten the external release body to the load bearing box
system using the two supplied M8 screws (Fig. 19 ref. 1)

The installation of the hydraulic release could have let air in the
circuit, causing irregular operation like an incorrect movement
of the leaf and excessive noise during operation.
To correct this problem, operate as follows:
1) Command an opening movement of the gate.
2) During the leaf movement, loosen the opening bleed screw
(Fig.21 ref.1 )
Set nut
If the gate must be moved manually due to a power failure or
operator’s malfunction you can use the built in hydraulic release
device with the release handle (Fig.17):
1) Remove the cover from the load bearing box.
2) Turn the release handle:
- To release, turn the hanlde counter-clockwise by one turn. (
Do
not completely unfasten the screw to avoid oil spills
)
- To re-engage the hydraulic operation, turn the screw clockwise
up to the mechanical stop point. (
Do not overtighten
)
