Mounting the Opener
Step 11
Attach the opener to the securely bolted post bracket assembly and gate bracket using clevis pins, washers, and hairpin clips,
or optional Pin Locks (see Accessory Catalog). Verify that the opener is level and adjust the post bracket assembly if
necessary.
Installation of the Positive Stops
The positive stops hold the gate firmly in the open and closed positions. The positive stops also form the
boundaries of the gate operating arc and help stabilize the gate. Moreover, a stable gate maintains the long life of
your automatic gate opener system. To further enhance the stability and security of your gate, install the optional
Mighty Mule Automatic Gate Lock
®
(see Accessory Catalog).
Step 12
With the gate at its maximum open position, measure the
distance from the gate hinge to the end of the gate. At
approximately
2
/
3
of this distance (using the hinge as your
starting point), place a mark on the ground directly under
the gate. Install the open position stop at this mark (see
illustration). The open position stop post may be made of
wood, metal, or concrete and should be firmly secured in the
ground (we recommend setting it in concrete). When the
open position stop post is in the ideal position, the gate will
strike the post just as the opener motor shuts down.
Step 13
Remove hairpin, clevis pin, and washer from front mount
and close the gate (remember to support opener). Fasten the
closed position stop plate to the end of the gate frame on the
gate centerline, but
do not
tighten it completely. Slide the
stop plate toward the fence post until they touch (see
illustration). Once you have moved the stop plate to the
correct position, tighten its hardware completely.
Use the appropriate hardware for your type of gate (use
U-bolts if you have a tube or chain link gate; wood or lag
screws for wood gates; etc.). This hardware is not provided.
