NOTE: Installation requirements vary with garage construction. Hanging brackets should be angled to provide rigid support. Not all hanging material is provided. Diagonal supoport for added stability. For finished ceilings use an angle iron cross piece, secured into ceiling joist with 5/16” x 1-1/2” lag screws.
ATTACHING DOOR BRACKET CAUTION Fiberglass, aluminum or lightweight steel doors WILL REQUIRE reinforcement before installation of door bracket. If your door doesn’t have a reinforced mounting support built in, contact door manufacturer or garage door professional for instructions on reinforcement or reinforcement kits for using automatic door openers.

Secure with the 5/16” x 1-1/8” clevis pin and hitch pin. 3 Rotate the curved door arm upward to meet the straight door arm connected to the trolley. Align the two door arms so that the holes in both arms overlap.
INSTALLING PHOTO BEAMS WARNING • Photo beams MUST be installed on the garage door to prevent serious injury or death. • This required safety reversing sensor MUST NOT be disabled at any time. • Install the photo beams no higher than 6” above the floor. NOTE: The photo beams infrared light must not be obstructed by the door, or by any part of the door hardware. Use wooden spacers between the beam brackets and wall if necessary to create proper clearance.
5 Photo beam wires IMPORTANT: Be careful to route the photo beam wiring away from any moving parts of the door or opener. DO NOT route wires along the rail. 1/2” DO NOT pierce wire with staples 3J For non-prewired installations, route the wires from the photo beams using insulated staples supplied, up the wall above the door hardware, over to the center of the door, then along the ceiling, and back to the opener head. Cut the wires about 6” longer than needed to reach the opener terminals.
INSTALLING THE WALL STATION The Mighty Mule MM9545M and MM9434K come with the MMW200 WiFi wallstation and the MM9333H comes with the MMW100 wallstation without WiFi capability. Installation is the same but functions are different. Illustrations below will highlight the differences.
Mount and Wire the Wall Station Mount the wallstation to the wall or existing electrical gang box using one of the methods shown.
SMART CONTROL Wi-Fi WALL STATION (if applicable) This Smart Control© Wall Station allows operation of the light and door using the buttons, but it does much more when paired with our Android or iOS application. It can operate your garage door, manage your family’s access, control lights and inform you of people coming and going, all while you are on the go.
INSTALLING or REPLACING THE BACK-UP BATTERY (if applicable) The 12 Volt, 5.4 Amp hour battery (Model MMB100) provides power to the opener in the event of power outage. IMPORTANT: Always make sure the opener head unit’s AC power cord is not plugged in before installing or changing the battery. 1 2 12 Volt, 5.4 Amp hour Battery Loosen the 4 housing screws (no need to completely remove them) and remove the housing.
CONNECTING POWER WARNING • To prevent electrocution or fire, installation and wiring must be in compliance with local electrical and building codes. • To reduce the risk of electric shock, this equipment has a grounding type plug, that has a third (grounding) pin. This plug will only fit into a grounding type outlet. If the plug does not fit into the outlet, contact a qualified electrician to install the proper outlet. Do not change the plug in any way.
ALIGNING PHOTO BEAMS NOTE: If the door remains idle for 5 minutes, the beam LED will turn off to save power. The beam power turns on for 5 minutes when door moves down to the fully closed position. The beam power can be restored for 5 minutes by pressing the light button on the wall station. The photo beam has two components, a sender and a receiver. The sender produces a narrow infrared beam that travels across the bottom of the door opening to the receiver.
PROGRAMMING OPENER AND CONTROLS PROGRAMMING TRAVEL LIMITS Adjusting the Open and Close Limits The limit settings control how far the door will open and close. Set the limits so the door opens just short of any door stops, and closes at the floor level. Use the wall station or a transmitter to test operate the door. If required, use the following steps to adjust the limits. NOTE: If the door does not open or gives an error, adjust the force factor as shown on page 25.
SAFETY REVERSAL SYSTEM TEST WARNING Always perform the Safety Reversal System Test after making any adjustments to the opener. PERFORM THE SAFETY REVERSAL SYSTEM TEST MONTHLY! The opener determines that there is an obstruction if a higher than expected amount of force is detected during a door cycle. If an obstruction is encountered during a closing cycle, the opener and door will stop then fully open. If an obstruction is encountered during an opening cycle, the opener and door will stop.
INSTALLING AND PROGRAMMING KEYPAD (if applicable) DESCRIPTION: To activate the garage door opener, the user enters their unique 1 to 6 digit long code on the unit’s keypad and presses the up/down ( ) button. For up to 30 seconds after the last activation, the keypad can be re-triggered by simply pressing the up/down ( ) button again. This allows the user to stop or reverse the opener quickly, without having to re-enter their code. The keypad has built-in lighting for use at night or in dark areas.
Adjusting the Force Factor (Installation Option, Normally Not Used) The opener uses the peak force measured during each of the last four complete cycles plus a “force factor” to calculate the maximum allowed force setting for the current door cycle. If the calculated maximum force setting is exceeded during the current door cycle, the opener reacts to the obstruction.
USING THE GARAGE DOOR OPENER Opening the Door 1 With the door in view, press the wall station’s UP/DOWN button or the button assigned to the opener on the remote control, or enter a valid access code and press ( ) on a wireless keypad. 2 When the opener is activated, the opener’s light will turn on and the door will begin to open. Remote Transmitter 3 The door will open until the open limit is reached.
USING THE WALL STATION Vacation Lock for Additional Security 1 Open the wall station’s cover to access the Programming Buttons. Press the LOCK ( ) button on the MMW200 and slide the LOCK SWITCH to ( )on the MMW100 to prevent remote controls from opening the door after the door is completely closed. When the Vacation Lock is activated, the remote controls can close the door, but not open it. The door can still be opened or closed by using the wall station’s UP/ DOWN pushbutton.
Mighty Mule Smart Control APP After you complete the opener installation and everything is working correctly, use your smart phone to Download, Register and Activate the Mighty Mule Smart Control APP. Use your smart phone to download and install the “Mighty Mule Smart Control” app. On initial use you’ll be asked to register and create an account. Once complete, sign in with your new account information.
PHOTO BEAM TEST 1 Check that the opener has power. The green LEDs on the sender and receiver should be lit. PHOTO BEAM INDICATOR TABLE GREEN ON POWER ON 2 If the receiver’s green LED is on, but the red LED is off, GREEN OFF POWER OFF the receiver has power but is not detecting the infrared RED ON BEAM OK - NO BLOCKAGE beam from the sender. The red LED might flash when RED OFF BEAM BLOCKED OR MIS-ALIGNED the beam is partially detected.
REPLACING REMOTE BATTERY: When the red light on the remote glows dimly, or fails to light at all when the remote is activated, the batteries need replacing. REPLACING THE REMOTE CONTROL BATTERY 1 Open the remote’s case. USE COIN OR VISOR CLIP IN SLOT TO OPEN CASE 2 LIFT OFF TOP OF CASE 3 CARFULLY REMOVE THE BOARD Remove the circuit board. Replace old battery with new Type CR2032 battery. Re-assemble the remote.
MAINTENANCE AND ADJUSTMENTS Garage Door Opener Maintenance Weather conditions may affect the door operation which could require some re-setting of the opener’s adjustments. Doors may swell and become heavier during wet periods, door hinges and rollers might bind during cold periods. To insure safe operation of the door, perform the following tests, including any additional test steps described. Every Month 1 With the door closed, pull the red release handle to disconnect the opener from the door.
TROUBLESHOOTING Door Operation Troubleshooting These conditions occur when the door is in motion or while attempting to move the door. Feedback is given via light flashes and an audible alarm once the door stops travel. WARNING If a battery backup is used, the opener may start moving the door even with AC power disconnected.
