7.1 HYDRAULIC RELEASE OF THE OPERATOR
If the gate has to be moved manually due to a power cut or
fault of the automated system, use the hydraulic release device
with the release key (Fig.26 ref.
b
):
1) Remove the cover from the bearing case.
2) Turn the release screw (Fig.26 ref.
a
) inserting the triangular
recess of the supplied key (Fig.26 ref.
b
):
- To
RELEASE
, turn the screw anti-clockwise by one turn. (DO NOT
COMPLETELY UNFASTEN THE SCREW TO AVOID OIL COMING OUT.
- To
SHUT-DOWN
again, turn the screw clockwise up to the
mechanical stop point.
7.2 MECHANICAL EMERGENCY RELEASE
(OPTIONAL)
For the S800H operator, a manual mechanical emergency
release is available as an optional item.
If the gate has to be moved manually due to a power cut or fault
of the automated system, use the release key device.
The device is inserted on the gate support bracket (Fig.27 ref.
a
) and enables you to release the system from both inside and
outside the premises.

RELEASE LEVER
Procedure for manual leaf operation:
1) Open the protective hatch (Fig.28 ref.
b
).
2) Insert the release key in the lock (Fig.28 ref.
c
) and turn it clock-
wise sense up to its stop point.
3) Pull the release lever toward you (Fig.28 ref.
a
).
4) Move the leaf by hand.
Procedure for restoring the system to normal operation:
1) Move the release lever back to its rest position (Fig.27)
2) Insert the release key in the lock (Fig.28 ref.
c
), turn it in the
opposite direction up to the stop point and remove it.
3) Close the protective plug of the lock.
4) Move the leaf manually until it hooks on the shut-down
bracket.

The presence of air in the hydraulic circuit causes the automated
system to operate incorrectly, i.e. a faulty movement of the leaf
and too much noise while operating.
Procedure to avoid this problem:
1) Command the gate to open.
2) While the leaf is moving, loosen the opening bleed screw
(Fig.29 ref.
a
)
8.1 BLEEDING OPERATIONS
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 TOPPING-UP OIL LEVEL.
8 MAINTENANCE
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 perfect
operation of the gate hinges.
The safety devices installed on the system must be checked
every 6 months.
