Step 5
After verifying that you have the best position for
the post pivot bracket in the open position, insert
the 5/16" x 1-3/4" 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 closed position.
TIP: Turn the post pivot bracket over for more hole
alignment options. You can also move the entire
post bracket assembly to different positions on the
post.
Step 6
Be sure the position of the gate opener and brackets
allows for 2” of clearance between the gate and the
opener in both the open and closed positions (A),
and maintaining a maximum distance of 15” from
the clevis pin opening of the retracted opener arm to
the gate bracket with the gate in the closed position.
(B) see graphic to right. This mounting position will
give the opener the most efficient leverage point
for operation and provides the least possible pinch
area.
Again, check the clearance and be sure that the gate
opener is not binding at the post pivot bracket.
If you don't have the required clearance, or if the gate opener is
binding on the post pivot bracket, remove the 5/16" x 1-3/4" bolt and
readjust the post pivot bracket.
Step 7
When the post bracket assembly is in the optimum position for clearance and freedom of movement,
reattach the opener to the gate bracket (gate in the open position); recheck the gate opener level; make
sure the brackets are clamped securely. Secure the 5/16” x 1-3/4” bolt with a 5/16” washer and 5/16” nut.
Step 8
Mark reference points for bolt holes on the post through middle of
post bracket assembly 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 fence and gate.
