To release the operator, remove the plastic cover, insert the key
and turn the release lock counter-clockwise for about one turn.
(Fig. 23 ref. 1)
To re-lock the operator, turn the release lock clockwise until reach-
ing the stop point, do not force (Fig. 23 ref. 2)

3) Let air come out from the hydraulic circuit through the bleed
screw until non-emulsified oil comes out.
4) Tighten the bleed screw before the operator ends the opening
cycle.
5) Command a closing movement of the gate.
6) During the leaf movement, loosen the closing bleed screw
(Fig.21 ref. 2)
7) Let air come out from the hydraulic circuit through the bleed
screw until non-emulsified oil comes out.
8) Tighten the bleed screw before the operator ends the closing
cycle.
9) Repeat the operations, if necessary.
10) Restore the oil level until it is just under the cap, using the oil
supplied (Fig. 22 ref.1).
The presence of air in the hydraulic circuit causes the automa-
ted system to operate incorrectly, i.e. a faulty movement of the
leaf, encoder faults and too much noise while operating. Please
refer to the procedure illustrated in paragraph 4.2.2 to correct
this problem
THE S800H OPERATOR IS SUPPLIED WITH THE HYDRAULIC
CIRCUIT ALREADY AIR FREE. DO NOT BLEED. BLEEDING IS
ONLY NECESSARY IN THE EVENT OF MAINTENANCE OF THE
HYDRAULIC SYSTEM, OR INSTALLATION OF THE HYDRAULIC
MANUAL RELEASE
Run a functional check of the system at least every 6 months,
with special attention to the efficiency of the safety and release
devices (including the thrust force of the operator), and to the
smooth operation of the gate hinges.
