3. MANUAL OPERATION
If the gate must be moved manually due to a power outage or
other failures use the manual release device as follows:
- Insert the triangular key on the release screw located in the lower
part of the flange (Fig.15).
- Turn the release key counter-clockwise for about two turns.
- Open or close the leaf manually.
To re-lock the operator turn the key clockwise until it stops.
4. MAINTENANCE
Run a functional check of the system at least every 6 months.
Pay special attention to the efficiency of the safety and release
devices (Including the thrust force of the operator), and the
perfect operation of the gate hinges.
Checking oil level:
Periodically check the oil level inside the tank
• Cut power to the system.
• Position the operator vertically, with the rear flange high up.
• Remove the oil filling plug.
• Insert a screwdriver until it comes into contact with the electric motor
as shown in Fig. 16.
• Remove the screwdriver and check oil level as shown in Fig. 16.
USE ONLY FAAC HP FLUID OIL
Periodically check the correct adjustment of the anti-crushing
safety device (BY-PASS) and the efficiency of the release system
to allow manual operation.
The safety devices installed on the system must be checked
every 6 months.

Fig. 14
The 402 operator has an anti-crushing safety device which limits
the operator’s force if an obstacle is encountered while the gate
is moving.
To adjust the intervention threshold of the anti-crushing system,
turn the By-Pass screws on the flange (Fig.14).
OPEN screw (green) : gate opening direction.
CLOSE screw (red) : gate closing direction.
(the opposite applies in case of outward opening)
To reduce pressure, turn the screws anti-clockwise.
To increase pressure, turn the screws clockwise.
After the adjustment is complete attach the protective plastic
cover over the by-pass screws using the supplied self tapping
screws.
