6.
Secure the operator to the rear bracket using the supplied
bolt, as indicated in Fig. 15.
7.
Move the gate leaf to the closed position.
8.
Bring the operator, together with the front bracket,
alongside the leaf.
9.
Check that the operator is horizontal using a level
on the
bottom side of the operator as indicated in Fig. 16
,
and temporarily secure the front bracket with clamps or
two welding spots.
NOTE:
The axis of the holes of the front bracket must be
aligned with the axis of the holes of the rear bracket,
as shown in Fig. 17.
If the structure of the gate does not allow reliable
mounting of the front bracket it must be reinforced with
plates or similar.
10.
Disengage the operator’s manual release (see Par. 3) and
move the leaf manually, checking that it completes the
entire swing, stopping at the mechanical stops.
If during this test the operator hits the leaf of the gate, the
value
E
may be increased, (see Fig. 4), up to a maximum
of 4
½
inches, using appropriate spacers placed between
the front bracket and the gate's leaf.
11.
Make all the necessary corrections and repeat the
procedures from step 9 if needed.
12.
Permanently secure the front bracket, using a suitable
system as indicated in Fig. 18.
if the front bracket will be welded directly to the leaf,
the operator must be temporarily removed. Wait for the
bracket to cool before reattaching the operator.

Wiring The Operator
The operator is supplied with the cable already connected.
If the cable has to be replaced, use a UL rated cable for
outdoor use.
2.5
Mechanical Stops
The S418 operator is supplied with mechanical stops on
opening and closing as standard. These may be used in place
of mechanical stop-points for the leaf. For adjustment of the
stops, proceed as follows:
2.5.1 Mechanical Stop at Opening
1.
Disengage the operator’s manual release (see Par. 4).
2.
Manually move the leaf into its opening position.
3.
Loosen the bolt, Fig. 19 ref. 1. The bolt does not need
to be completely removed.
