(E5 pos. 4) using a CH7 hexagonal wrench.
Fit the protective sheath to the power supply cable
pos. 5) if necessary.
Caution
One drop of hydraulic oil coming out of the duct
created by the screw elimination (E5 pos. 4) is
normal.
Information
After installation, an appropriate warning sign must
be attached to the gate (E6 pos. 2.)
When completely assembled, the operator should
appear as shown in the fi gure

4.5.5 Bleeding

!
Warning
Before proceeding in setting the operator, bleed it.
Start the operator after having checked the setting of the
pressure relief valves and move it to stroke end either in
open or close position. Rotate on the key (see paragraph
6) and lock and unlock the operator a dozens of times.

CHECKS AND ADJUSTMENTS

5.0
CHECKING AND ADJUSTING THE THRUST
FORCE
With the gate leaf moving, measure the thrust force
at the end of the gate leaf, using a dynamometer
pos. 1).
The thrust force must never exceed
If necessary, adjust the working pressure of the
operator.
Using a broad, fl at-headed screwdriver, turn the control
valves clockwise to increase the pressure and counter-
clockwise to reduce it.
Adjust both opening (silver - E8 pos. 2) and closing
pressure (gold - E8 pos. 1).
Caution
• The opening thrust of the gate leaf should be set
slightly higher than the closing thrust.
• After making the settings, make another check
with the dynamometer to see if the thrust force
corresponds to the setting; if it doesn't, then the
setting needs to adjusted again.
• If the gate leaf requires an excessively high
pressure to move it, then make another thorough
check of the mechanical parts, the plumb and the
free movement of the gate leaf itself.

EMERGENCY MANOEUVRE - USE OF THE MANUAL RELEASE

In the event of a power failure, release the operator in order to open the gate by hand.
To gain access to the release valve, it is enough to loosen the screw (E9 pos. 2) and open the small cover (E9
pos. 3) by rotating it.
Unlock the operator by turning the triangular key provided (E9 pos. 1) counter-clockwise.
After the operation, re-lock the operator by turning the key clockwise.
