ECHANISM
For installation of the locking cap cover see page 10. To
access the keyhole, slide the key-hole cover in the
direction of the arrow (see Figure 3). Insert the key and
turn it counterclockwise one full turn to disengage the
operator’s hydraulic system. You can now move the gate
leaf slowly by hand to open or close the gate.
Operating the gate leaf by hand is necessary during
installation and is useful during power failures.
You re-engage the hydraulic system by turning the key
clockwise one full turn. Remove the key and slide the
cover closed.

Modification of the rear bracket may be
necessary to achieve these dimensions (I.e.,
cutting or extending the bracket provided)
If you have a steel gate post, weld the rear bracket
directly to it. If the gate post is made of any other
material, attach the optional mounting plate, with lag
bolts or anchors, and weld the bracket to it.
