Mighty Mule 362-D Installation Instructions

PUSH-TO-OPEN
gates open out from the property (opener arms
extend
to open). Push-To-Open Brackets are required
for this type of installation, one for each gate [FM148] page 26).). In a Push-To-Open installation, the opener is installed
while the gate is
in the closed position and the opener fully retracted
.
Swinging gates MUST NEVER open into public access areas!
Step 1: Read "Installation of the Gate Opener" on page 7.
Step 2: Determining The Mounting Position of The Post Bracket Assembly
A. Insert the
3
/

" x 1
1
/
2
" bolt through the center hole of the post
brackets and post pivot bracket. Secure with a
3
/
8
" washer
and
3
/
8
" lock nut. DO NOT
overtighten
the lock nut (the post
pivot bracket will have to be adjusted later).Attach post bracket
assembly to the rear mount of the opener with a clevis pin and
a
3
/
8
" washer. Secure the clevis pin with a hairpin clip. Attach
gate bracket to the front mount of the opener with a clevis pin
and a
3
/
8
" bushing. Secure the clevis pin with a hairpin clip.
B. With the gate in the closed position (up to 110º from its open
position), and the opener fully retracted, adjust the post
bracket assembly and gate bracket until the opener is level.
While holding the opener level, use C-clamps to temporarily
keep the post bracket assembly and gate bracket in their
respective positions on the fence post and gate.
IMPORTANT:
Be sure the position of the gate opener and
brackets allows for 1" of clearance between the gate and the
opener in both the open and closed position, while at the same
time maintaining a maximum distance of 13" from the end of
the opener arm to the gate bracket with the gate in the
open
position. This mounting position will give the opener the most
efficient leverage point for operation and provides the least
possible pinch area.
C. After verifying that you have the best position for the post
pivot bracket in the closed position, insert the
5
/
16
" x 1
1
/
2
" bolt
through the aligned holes of the post bracket and post pivot
bracket to hold it in place. Remove the clevis pin from the front
mount and
while supporting the gate opener
, swing the
gate and gate opener to the
open
position. Again, check the
clearance and be sure that the gate opener is not binding at
the post pivot bracket.
IMPORTANT:
If you don't have the required clearance, or if
the gate opener is binding, remove the
5
/
16
" x 1
1
/
2
" bolt and
readjust the post pivot bracket. TIP: Turn the post pivot bracket
over for more hole alignment options.
D. When the post pivot bracket assembly is in the optimum
position, reattach the opener to the gate bracket (gate in the
closed position); recheck the gate opener level; make sure the
brackets are clamped securely. Mark reference points for bolt holes on the post through middle of post bracket
slots. Mark reference points for bolt holes on the gate cross member through middle of gate bracket slots. After
marking your reference points, remove the opener and brackets from the post and gate.
E. Drill
3

" holes through post as marked. Fasten post bracket assembly to the post using two
3
/
8
" x 8" bolts,
washers and lock nuts
.
You must use bolts that completely penetrate the post.
