IMPORTANT SAFETY INSTRUCTIONS Entrapment Zones for a proper Pull-To-Open installation: Zone 1 – leading edge of the gate and the fence post. Zone 2 – between the gate and the gate post. Zone 3 – the path of the gate. Zone 4 – the space between the gate in the open position and any object such as a wall, fence, tree, etc. Zone 5 – pinch points between the opener and gate. II. During Installation 1. Install the gate opener on the inside of the property and fence line.
PAGE 8
IMPORTANT SAFETY INSTRUCTIONS III. After Installation 1. Attach the warning signs (included) to each side of the gate to alert the public of automatic gate operation. It is your responsibility to post warning signs on both sides of your gate. If any of these signs or warning decals become damaged, illegible or missing, replace them immediately. Contact GTO for free replacements. 2. The gate is automatic and could move at any time, posing a serious risk of entrapment.
PAGE 9
IMPORTANT SAFETY INSTRUCTIONS Secondary Means of Protection Against Entrapment As specified by Gate Operator Safety Standard, UL 325 (30A.1.1), automatic gate openers shall have an inherent entrapment sensing system, and shall have provisions for, or be supplied with, at least one independent secondary means to protect against entrapment. The Mighty Mule® utilizes Type A, an inherent (i.e., built-in) entrapment sensing system as the primary type of entrapment protection.
PAGE 10
IMPORTANT SAFETY INSTRUCTIONS Required Safety Precautions for Gates Install Warning Signs Warning signs alert people of automatic gate operation and are required when installing the Mighty Mule® E-Z Gate® Opener.

Installation Overview Pull-to-Open Gates (Gate Opens into the Property) The diagram shown below is an example of a pull-to-open installation on a chain link fence and dual gates. Mounting the openers on a masonry column requires special procedures; see Column Installation Information on page 38 if you intend to mount the openers on columns. Furthermore, if you have push-to-open gates, you will need to purchase two (2) pushto-open brackets (see Accessory Catalog) to properly configure your system.
PAGE 16
Installation of Mounting Hardware The position of the post bracket determines the leverage and efficiency of the opener. The post bracket position also sets the clearance between the opener and gate in the open and closed positions (minimum 2 inches). The curved design of the post bracket works well for installations on round and square fence posts. Because the post bracket carries the entire thrust of the active opener, bolts that completely penetrate the fence post must be used.
PAGE 17
Determining the Mounting Position of the Post Bracket Assembly and the Gate Bracket Post Bracket Assembly Step 3 IInsert the 3/8" x 2" bolt through the center hole of the post brackets and post pivot bracket as shown. Fasten a 3/8" lock washer, 3/8" washer and 3/8" nut on the end of the bolt. DO NOT overtighten the nut because the post pivot bracket will have to be adjusted later. NOTE: The following steps are intended for pull-to-open gate installations.
PAGE 18
IMPORTANT: While determining the mounting point for the post pivot bracket assembly, be sure that the position allows for minimum 2 inches of clearance between the gate and the opener in both the open and closed positions, as shown in the diagrams below. This clearance will give the opener the most efficient leverage point for opening and closing the gate and more importantly provides the least possible pinch area.
PAGE 19
Installing the Post Bracket Assembly and Gate Bracket Step 7 Mark reference points for bolt holes on the fence post through middle of bracket slots. Marking reference points in this manner allows room for adjustment when mounting the post bracket assembly and gate bracket. After marking your reference points, remove the opener and brackets from the fence and gate. EXAMPLES Mark fence post through TOP VIEW middle of bracket slots Step 8 and drill 3/8" holes Drill 3/8" holes into fence post as marked.
PAGE 20
Mounting the First Opener Step 11 Attach the opener to the securely bolted post bracket assembly and gate bracket using clevis pins, bushings, and hairpin clips, or optional Pin Locks (see Accessory Catalog). Verify that the opener is level and adjust the post bracket assembly if necessary.
PAGE 21
Installation of the Closed Position Stops The Mighty Mule® Gate Openers firmly hold the gates in the closed position using positive stops. The positive stops help stabilize the gate leaves in the closed position. To further enhance stability and security, we strongly recommended using an optional Mighty Mule® Automatic Gate Lock (see Accessory Catalog) with your dual gate.
PAGE 22
Step 2 Install a low profile ground stop (not provided) beneath the SLAVE gate stop plate. Closed Position Stop Plate mounted on the gate leaf that CLOSES FIRST Mount Vertically The ground stop needs to be positioned near the end of the gate as shown in Illustration A and may be made of metal or concrete and should be firmly secured in the ground (we recommend setting it in concrete).
PAGE 23
Mounting the Control Box Step 1 Mount the control box using the screws (provided) or another secure mounting method. The 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. Use mounting holes and screws provided to mount control box to a secure surface.
PAGE 24
Connecting Opener Power Cables MASTER Operator Step 4 Insert the stripped power cable wires into the appropriate terminals on the MASTER CABLE terminal block. The green wire should be inserted into the GRN terminal, the white wire into WHT, the blue wire into BLU, brown wire into BRN, and the orange wire into the ORG, terminal.
PAGE 25
Powering the System Installation of the Transformer IMPORTANT: • The transformer is designed and intended for indoor use. If the transformer can be plugged only into an outside electrical outlet, a weatherproof cover or housing (available at local electrical supply stores) must be used. • All low voltage wire used with the Mighty Mule® Gate Opener must be 16 gauge dual conductor, multi-stranded, direct burial wire (see page 22 and the accessory pages). Do not run more than 1000 feet of wire.
PAGE 26
IMPORTANT INFORMATION ABOUT LOW VOLTAGE WIRE The only wire acceptable for use with GTO products is 16 gauge multi-stranded, low voltage, PVC sheathed wire. This particular gauge enables the transformer to provide an adequate charge through the control board to the battery at distances up to 1000 ft. DO NOT use telephone wire or solid core wire. Unlike multi-stranded wire, these types of wire are inadequate for use with your gate opener system.
PAGE 27
Step 6 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. Transformer Step 7 Plug the transformer into the electrical outlet. (Use of a surge protector with the transformer is strongly recommended.) HINT: Keep a few mothballs in the control box to discourage insects from entering it and damaging the control board.
PAGE 28
CONTROL BOARD SETTINGS DIP Switches NOTE: Leave DIP Switch #3 in the OFF position until installation is complete, to prevent gate from automatically closing during installation. DIP DIP Switch #2 - Warning Buzzer ON - Buzzer warning enabled (factory preset). OFF - Buzzer warning disabled. The Warning Buzzer alerts you when the gate opener is beginning to either open or close the gate. It sounds for the first 2 seconds in each direction.
PAGE 29
Setting the Closed Position Limits for Pull to Open Applications TURN CONTROL BOX ON Your Mighty Mule® has two Limit Settings 1) OPEN Limit setting: (Gate in the OPEN POSITION / FACTORY SET NOT ADJUSTABLE) The open limit setting is the fully open position. 2) CLOSED Limit setting: (Gate in the CLOSED POSITION) To achieve optimum closed position, you are required to complete the following SEVEN STEPS: Step 1 Confirm that the power switch is in the ON position, and the gates are in the OPEN POSITIONS.
PAGE 30
TESTING YOUR CLOSED LIMIT SETTING: Press your entry transmitter and allow your gates to close. If CLOSED positions are not correct or need to be changed, you will need to CLEAR your CLOSED LIMIT settings and follow Steps 1-7 again. CLEARING PROGRAMMED CLOSED LIMIT SETTING: If you make a mistake and set the limit at the wrong position – press your transmitter to return the gates to their fully opened positions, then press and hold the 'LEARN MAST LIMIT' or 'LEARN SLV LIMIT' button for 5 seconds.

Push to Open Installation Swinging gates shall not open into public access areas! A "Push-to-Open" gate opens out from the property. A Push-to-Open Bracket is required for this type of installation (see Accessory Catalog). If you have a pull-to-open gate (gate opens into the property), return to page 13; step 3. In a PUSH-TO-OPEN installation the openers are installed while the gates are in the closed position.
PAGE 37
Step 3 With the gate in the fully closed position and the opener retracted, swing the opener to the gate. Mark reference points for bolt holes on gate cross member through middle of gate bracket slots. The opener must be level. (Some vertical adjustment is possible by sliding the post bracket assembly up and down.) Drill 3/8" holes into the gate cross member as marked. Fasten gate bracket to cross member using (2) 3/8" x 3" bolts, washers, lock washers, and nuts.

Column Installation Information IF THIS OPENER WILL BE USED WITH GATES THAT ARE MOUNTED ON MASONRY, BRICK, OR ROCK (etc.) COLUMNS: READ THE FOLLOWING CAREFULLY BEFORE PROCEEDING A. The simplest solution is to install the opener in a push-to-open configuration (requires Push-To-Open Bracket, see Accessory Catalog). The minimum clearance is easier to achieve and clearance is no longer a problem, since the opener will be pushing the gate away from the column instead of pulling it toward the column.
