4.1 CHECKS AND SETTINGS
With the gate leaf moving, measure the thrust force
at the end of the gate leaf, using a dynamometer (
D2
pos.
1
). The thrust force must never exceed 15 kg
(147 N). If necessary, adjust the working pressure
of the operator.
Using a broad, fl at-headed screwdriver, turn the control
valve clockwise to increase the pressure and anti-
clockwise to reduce it.
The settings are made both on the opening control
valve (silver -
D3
pos.
2
) and the closing control valve
(gold -
D3
pos.
3
).
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.

When completely assembled,the operator should
appear as in the illustration (
D4
pos.
2
).
Caution
To gain access to the release key, it is enough
to slide back the hatch (D4 pos. 3); after locking
or releasing operations, remember to close the
hatch again.
After installation, an appropriate warning sign must be
attached to the gate (
D4
pos.
4
).
