Note: If you are installing the 760 Operator with
an extension arm, some of the constraints do not
apply to your gate leaf. See the section
"Installing an Extension Arm" for more
information (page 25).
Manual Release
Note: The 760 CBAC provides a Manual Release
for manually operating the gate. Although the
760 SB and the 760 SBS come with this release
mechanism, it is not necessary to use this feature
to release the gate. The SB and SBS have no
internal locking and can be pushed manually at
any time.
The Manual Release mechanism on the Standard
models is a built-in release device of the 760 Operator
(see Figure 6). This device is accessible from both
sides of the gate. You disengage the hydraulic
operation of the operator by opening the access door
(there is one on either side of the manual release
housing), inserting the triangular key, and turning the
key toward the gate post one full turn. Then you can
move the gate by hand to open or close the gate.
Operating the gate by hand is necessary during
installation and is useful during power failures.
To re-engage the hydraulic operation of the gate, turn
the key away from the gate post until resistance is met.
Open the access door
to the release device 1.
2. Insert the key and turn
it one full turn toward the
gate post for release.

Installing the 760 Operator
Installing the 760 Operator consists of the following
steps:
•
Install the load bearing box, electrical
conduit, and drain pipe
•
Secure the load bearing box
•
Install the gate leaf shoe
•
Install the gate leaf
•
Install the operator in the load bearing box
•
Install the control panel
•
Adjust the hydraulic pressures for the
operator
•
Check the motor rotation
•
Fine-tune the bypass valve pressures
Install the Load Bearing Box
You need to excavate a cavity for the load bearing box
of the 760 Operator according to the dimensions
shown in Figures 4 and 7. (Your soil conditions will
also determine the size of the cavity.) Accurately
positioning the splined shaft of the pinion (inside the
mounting box) beneath the gate hinge is critical.
Proper alignment will ensure a full swing without
binding.
Note : You need to insure that the load bearing box is
well drained by means of pipes, gravel drainage, or
both, whatever is appropriate for your soil conditions.
Use one of the access holes in the load bearing box for
the drainage pipe leaving the box.
Install your electrical conduit through another hole in
the load bearing box. Use conduit of sufficient size
and quality to accommodate the high-voltage wiring
that must run between the operator (in the load bearing
box) and the control panel.
Caution : Be sure to conform to all applicable
electrical codes.
