CHECKS AND ADJUSTMENTS

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
(E6 pos. 1).
The thrust force must never exceed 15 Kg (147 N).
If necessary, adjust the working pressure of the operator.
Using a broad, flat-headed screwdriver, turn the control valves clockwise to increase the pressure
and counter-clockwise to reduce it.
Adjust both opening (silver - E7 pos. 2) and closing pressure (gold - E7 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.
5.0 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 (E8 pos. 2) and open the small
cover (E8 pos. 3) by rotating it.
Unlock the operator by turning the triangular key provided (E8 pos. 1) counter-clockwise.
After the operation, re-lock the operator by turning the key clockwise.
