Push-To-Open 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 29). 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 First Opener" on page
Step 2: Determining The Mounting Position of The Post Bracket Assembly
3 1
A. Insert the / " x 1 / " bolt through the center hole of the post brackets and post pivot bracket. Secure with a
8 4
3
lock washer and / " nut. DO NOT overtighten the nut (the post pivot bracket will have to be adjusted later).Attach post
8
bracket assembly to the rear mount of the opener with a clevis pin. Secure the clevis pin with a hairpin clip. Attach gate
bracket to the front mount of the opener with a clevis pin. Secure
the clevis pin with a hairpin clip. For pictorial reference see Steps
1, 2 and 3 on page 8.
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. For pictorial reference see Steps 3 on
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 stroke distance of 7" to 13" from center of hole in the end of the
retracted opener arm to the center of the hole in 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 / " x 1
16
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.
IMPORTANT: If you don't have the required clearance, or if the
5 1
gate opener is binding, remove the / " x 1 /
16 4
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 / 8 " holes through post as marked. Fasten post bracket assembly to the post using two
lock washers and nuts. You must use bolts that completely penetrate the post. Drill
member as marked. Mount gate bracket using two
NOTE: For mounting examples, see page 10.

A. Make sure the control box power switch is OFF.
B. Use small pliers to move the JUMPER for PUSH-TO-OPEN
applications.
C. Turn power switch ON. The control board is now configured to push
the gate open. (Keep the jumper, as it is necessary if there is ever a
need to convert the opener for Pull-To-Open).
Step 11: Set the Open Position Limit (Push-to-Open)
NOTE: Must have a transmitter that operates the gate. If not see Personalize Your Transmitter Setting on
The CLOSED limit is when the opener is fully retracted and the gate is in the closed position. The closed limit setting can only be
adjusted by moving the gate bracket. To achieve the optimum open position, you must adjust the OPEN Limit setting:
A. If not already ON slide the ON/OFF switch on the Control Box to the ON position and make sure the arms are in the
CLOSED POSITION (fully retracted).
B. Press and HOLD the FIRST Opener OPEN button on the control board and be prepared to RELEASE the button when
the gates reached the desired open position/limit. Use the JOG OPEN and CLOSE buttons to "fine tune" the gate position
if necessary.
C. Press and HOLD the SECOND Opener
OPEN button on the control board and
be prepared to RELEASE the button
when the gates reached the desired open
position/limit. Use the JOG OPEN and
CLOSE buttons to "fine tune" the gate
position if necessary.
D. NOTE: The opener arms must be
extended more than 7 inches to set
limits. With the gates in the desired open
positions PRESS and HOLD the SET
LIMIT button until the alarm and RED
Light come on. Then release the button.
E. NOTE: When the control box cover is removed the receiver range is reduced to less than 5 feet. Press the transmitter
button once and allow the gates to fully close. The alarm will beep once when both gates reach the CLOSED LIMIT.
This indicates the LIMITS for both arms are learned and stored in memory.
NOTE: If the gate stops and reverses you may need to adjust the Stall Force (see
F. Press the transmitter button and allow the gates to fully open to verify that they stop at the desired positions. Repeat
Steps B – E if correction is needed.
