Parts List – Opener and Mounting Hardware 2. Check Direction of Gate Swing The Mighty Mule 272 is designed for PULL-TO-OPEN installations. PUSH-TO-OPEN installations require two Push-To-Open brackets [FM148]. Push-to-Open Installation Instructions begin on page 21. ! WARNING Moving Gate Can Cause Injury Or Death Your Property 3. Prepare the Gates • • Gates must be plumb, level, and swing freely on their hinges. Wheels must NOT be attached to the gates.
Tools and Materials Installation Overview for Pull-To-Open Gates Tools Needed: Example of an installation on a chain link fence: PUSH-TO-OPEN installation instructions begin on page 21.
Install Post Bracket Assembly and Gate Bracket IMPORTANT: Determine which side of the driveway you will mount the control box. From this point on, the gate and gate opener on the same side as the control box will be referred to as the FIRST gate and gate opener. The gate and gate opener on the opposite side of the driveway from the control box will be referred to as the SECOND gate and gate opener.
Step 5 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 closed position. This mounting position will give the opener the most efficient leverage point for operation and provides the least possible pinch area.
Install the Closed Position Stop Plates The closed position stop plate is attached to the FIRST gate to help stabilize the gate leaf in the closed position. An optional low profile ground stop, when used with the closed position stop plate, provides a secure point for the SECOND gate to close against. To further enhance the stability and security of your gate, install a Mighty Mule Automatic Gate Lock [FM143] page 28).
Mount the Control Box Connecting the Battery Screw Placement Guides Step 1 Mount the Battery Box using the screws (provided) or another secure mounting method. The battery/control box must be mounted at least 3 feet above the ground to protect it from rain splash, snow, etc., and at least 3 feet from an AC power source to prevent electrical interference. Step 4 Battery Verify that the ON/OFF switch is in the OFF position.
Control Box Connect Opener Power Cables Step 3 Step 1 STATUS Bring FIRST power cable into the control box through a strain relief slot, leaving enough wire to reach the FIRST OPR. terminal block. Insert the individual power cable wires into appropriate terminals on the FIRST OPR. terminal block (white to WHT; green to GRN; red to RED; black to BLK). Tighten the set screws. A dab of petroleum jelly on each terminal will help prevent corrosion. 2nd OPR. PWR. MIN 120 SEC.
Step 6 At the AC outlet, strip 1/2" of insulation from the ends of the low voltage wire. Attach these stripped ends to the transformer terminals. A dab of household petroleum jelly on each terminal will help prevent corrosion. We suggest adding crimp on fork lugs to the end of each wire before attaching it to the transformer. Make sure the exposed wires do not touch each other! Set the CLOSED Position Limit for PULL-TO-OPEN Installation Your transmitter must be able to operate the gate.
Setting Dual Sense Detection and Auto Close Timer MMT103 Transmitter Learning the MM103 With system off, press and hold the transmitter button you want to use, then turn on the system and keep holding the button until the system "beeps" once.

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 7. A.
Connecting Additional Devices Solar Panel Instructions Mighty Mule strongly recommends the use of additional obstruction detection devices however we do not endorse any specific brand names. Only use products that are listed to be in compliance with any applicable UL safety standards and national and regional codes. NEVER USE TRANSFORMER AND SOLAR PANEL(S) AT THE SAME TIME! It will damage the control board! PLEASE NOTE: Contact sensors, non-contact sensors, shadow loops, etc.

Maintenance Monthly, test the obstruction and entrapment protection systems. Monthly, service the gate operator (make sure the power switch is OFF). Clean extended operator arm with a soft, dry clean cloth. After cleaning, apply a high quality silicon spray to a soft dry cloth and wipe the push/pull tube. DO NOT directly spray the tube!
