7.2 EMERGENCY MECHANICAL RELEASE
(OPTIONAL)
The S800H ENC operator has an optional manual emergency
mechanical release.
If you need to move the gate by hand due to a power failure
or a malfunction in the automation, act on the key-operated
release device.
The device is installed on the support bracket of the gate (Fig.27
ref.
) and makes it possible to release the system both from
inside and outside the property. NO BUSHES OTHER THAN THOSE
SUPPLIED ARE NECESSARY.

Proceed as follows to move the leaf by hand:
1) Open the protective cover (Fig.28 ref.
).
2) Insert the release key in the lock (Fig.28 ref. ) and turn it
clockwise to the stop.
3) Pull the release lever towards you (Fig.28 ref.
).
4) Move the leaf by hand.
Proceed as follows to restore the system to normal operation:
1) Put the release lever back to its home position (Fig.27).
2) Insert the release key in the lock (Fig.28 ref.
) and turn it an-
ticlockwise to the stop and remove it.
3) Close the protective cap of the lock.
4) Move the leaf by hand until it hooks the locking bracket.
The presence of air in the hydraulic circuit causes the automation
to malfunction. This can be seen when the leaf moves abnormally
and makes too much noise while operating.
Proceed as follows to solve the problem:
1) Command the gate to open.
2) While the leaf is moving, loosen the opening bleed screw
(Fig.29 ref.
).
3) Allow air to exit the hydraulic circuit through the bleed screw
until non-emulsified oil seeps out.
4) Tighten the bleed screw before the operator finishes the open-
ing cycle.
5) Command the gate to close.
6) While the leaf is moving, loosen the closing bleed screw (Fig.29
ref.
).
7) Allow air to exit the hydraulic circuit through the bleed screw
until non-emulsified oil seeps out.
8) Tighten the bleed screw before the operator finishes the clos-
ing cycle.
9) Repeat these operations several times.
10) Restore the oil level so that it is just below the filler cap (Fig.
30 ref.
).
8.1 BLEED OPERATIONS
The S800H ENC operator is supplied with the hydraulic
circuit without air. It does not need to be bled. It is only
necessary when performing maintenance on the hydrau-
lic system or when topping up the oil level.
8 MAINTENANCE
Perform a functional check of the system at least every six
months, paying special attention to the efficiency of the safety
and release devices (including the operator's thrust force) and
to perfect functioning of the gate hinges.
The safety devices installed in the system must be checked every
six months.
