9.1 OIL LEVEL CHECK
Check oil level periodically by unscrewing the filling plug (Fig.1
ref.
g
), check if the oil is just below the plug and, if necessary,
top up.
Topping-up operations must be done only with FAAC HP OIL.

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.24 ref.
a
)
3) Using the bleed screw, allow the air to come out from the
hydraulic circuit until non-emulsified oil appears.
4) Tighten the bleed screw before the operator finishes the
opening cycle.
5) Command the gate to close.
6) While the leaf is moving, loosen the closing bleed screw
(Fig.24 ref.
b
)
7) Using the bleed screw, allow the air to come out from the
hydraulic circuit until non-emulsified oil appears.
8) Tighten the bleed screw before the operator finishes the
closing cycle.
9) Repeat these operations several times.
10) Top up oil level, referring to the instructions in this chapter.
9.2 BLEEDING OPERATIONS
THE S700H 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.
9 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.
Also, periodically check quantity of oil inside the tank.
The safety devices installed on the system must be checked
every 6 months.
