Every Month

  1. With the door closed, pull the red release handle to disconnect the opener.
  2. Manually open and close the door fully. Check for binding, sticking, or rubbing. The door should move smoothly in both directions.
  3. Raise the garage door about halfway up. Carefully release it to see if it balances. It should stay in place. Close the door.
  4. Reconnect the opener by flipping the release lever up and manually moving the door until it reconnects.
  5. Perform the Safety Beam Test (Section 4).
  6. Perform the Safety Reversal System Test (Section 6, Steps 4-6).

Visual Description: The document includes a visual demonstrating the door balance test: the door should remain stationary when released halfway open.

Visual Description: The document shows how to disconnect the opener using the red release handle and how to reconnect it by flipping the lever up and moving the door.

After Servicing the Opener

  1. Perform the Safety Beam Test (Section 4).
  2. Perform the Open and Close Limit Adjustments (Section 5).
  3. Perform the entire Door Force Safety System Test (Section 6).

Every 6 Months

Check the belt or chain tension.

  • For belt-drive rails: Examine the tension spring in the traveler; it should be about 1" long.
  • For chain-drive rails: Examine the spacing between the turnbuckle and the rail; the turnbuckle should be slightly above the rail.

Note: Too much or too little chain tension can cause excessive sprocket noise.

Chain Adjustment
  1. Hold the turnbuckle with a flat blade screwdriver and loosen the two locknuts with a 7/16" end wrench.
  2. Twist the turnbuckle to adjust chain tension until the turnbuckle is slightly above the rail.
  3. Hold the turnbuckle and tighten the two locknuts.

Visual Description: The document shows a diagram for adjusting a chain drive, illustrating the turnbuckle, locknuts, and the action of loosening, twisting, and tightening.

Belt Adjustment

The tension spring in the traveler keeps the belt taut. The factory setting for the tension spring length is 0.9" long. If the tension spring is longer than 1", adjust the belt.

  1. Hold the traveler so the adjustment wheel is visible through the large slot.
  2. Use a flat blade screwdriver to turn the adjustment wheel to compress the tension spring until its length is between 0.9" and 1" long.

Visual Description: The document shows a diagram for adjusting a belt drive, highlighting the traveler and the adjustment wheel used to set the tension spring length.

Every Year

Check door hardware for lubrication needs. Lubricate door hinges, rollers, and bearings according to the door manufacturer's recommended procedures.

WARNING: Always perform the entire Door Force Safety System Test (see Section 6) after making any adjustments to the opener.

4. Testing the Infrared Safety Beam

The safety 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. If an object blocks the infrared beam while the door is closing, the door will stop, then reverse and fully open (the opener's light will flash three times).

As a safety feature, the opener will ignore signals from all remote controls if the door is open and the infrared safety beam is blocked or out of alignment. In this case, the door can be forced closed by pressing and holding the wall station's up/down arrow pushbutton (ensure the door area is clear).

WARNING: With the door closed, disengage the trolley from the chain during these alignment tests by pulling the red release handle.

Serious injury or death from a closing garage door may result from failure to test and adjust the safety reverse system. Repeat this test monthly and adjust as needed.

Safety Beam Test

  1. Check that the opener has power. The green lights on the sender and receiver should be lit.
  2. If the receiver's green light is on, but the red light is off, the receiver has power but is not detecting the infrared beam from the sender. The red light might flash when the beam is partially detected. This can be caused by mis-alignment or an obstruction. Adjust the safety beam sender and receiver while watching the receiver's red light (stay out of the beam while aligning it). When the red light stays on, the beam is aligned.
  3. With the door closed and the opener disengaged, press the wall station's UP/DOWN ARROW button to move the traveler to the up position (away from the door).
  4. Push the UP/DOWN ARROW button again. While the traveler is moving down (toward the door), block the safety beam. THE TRAVELER MUST STOP, THEN REVERSE TO THE UP POSITION. The opener's light should flash three times.
  5. Place an object in the path of the safety beam. Check that constant pressure is required on the wall station's UP/DOWN ARROW button to cause the traveler to move down. Release the pushbutton before the opener stops; the traveler should return to the up position.
  6. Note: The garage door opener will not respond to a CLOSE command from a radio transmitter if the safety beam is blocked.
  7. Reconnect the opener by flipping the release lever up and manually moving the door until it reconnects.

Visual Description: The document shows safety beam indicators: GREEN LIGHT (ON = Power On, OFF = Power Off) and RED LIGHT (ON = Beam Aligned, No Obstruction; OFF = Beam Blocked or Mis-aligned; BLINKING = Beam Aligned Poorly). It also shows a table summarizing these indicators.

Visual Description: The document illustrates adjusting the beam by aligning the sender and receiver until the red indicator light is solid.

Visual Description: The document shows checking for reversal by blocking the beam while the traveler moves down, confirming it reverses. It also shows checking the forced closure feature by placing an object in the beam's path and verifying constant pressure is needed on the wall station button for downward travel, and that the traveler returns up when the button is released.

Note: If the receiver's red light remains off, check for dirt on the lens, sunlight shining into the lens, or a short in the safety beam wiring.

5. Adjusting the Open and Close Limits

The limit adjustments control how far the door opens or closes and are located on the side of the opener. Limits should be set so the door opens just short of any door stops and closes right at the floor level. Each full turn of a limit adjustment equals about 2-1/2 inches of door travel.

CAUTION: Set the open and close limits carefully. Setting the limits beyond the door's travel distance could cause damage to the door, its hardware, or the opener.

Setting the Open Limit

  1. Start with the door in the closed position.
  2. Activate the remote control. Wait for the door to move to the open position and stop.
  3. Examine the door's position.
    • If the door needs to open more, turn the OPEN LIMIT adjustment clockwise 1/4-turn (towards UP) to raise the open limit.
    • If the door needs to open less, turn the OPEN LIMIT adjustment counterclockwise 1/4-turn (towards DOWN) to lower the open limit.
  4. Note: On jamb doors, set the open limit so the door stops just short of level.
  5. Activate the remote control. Wait for the door to move down a few feet, then activate the remote control again to stop the door.
  6. Repeat Steps 2-5 until the open limit is properly adjusted.

Visual Description: The document shows how to check where the door stops opening and how to set the open limit on a jamb door, illustrating the OPEN LIMIT ADJUSTMENT screw and the direction of turns.

Note: Setting the open limit too high can cause the opener to "buck" when starting down.

Setting the Close Limit

  1. Activate the remote control. Wait for the door to move to the closed position and stop.
  2. Examine the door's position.
    • If the door needs to close more, turn the CLOSE LIMIT adjustment counterclockwise 1/4-turn (towards DOWN) to lower the close limit.
    • If the door needs to close less, turn the CLOSE LIMIT adjustment clockwise 1/4-turn (towards UP) to raise the close limit.
  3. Activate the remote control. Wait for the door to move up a few feet, then activate the remote control again to stop the door.
  4. Repeat Steps 6-8 until the close limit is properly adjusted.

Visual Description: The document shows how to check where the door stops closing and how to set the close limit, illustrating the CLOSE LIMIT ADJUSTMENT screw and the direction of turns.

Note: If the door stops during opening or reverses during closing before reaching the limits, the door force adjustment needs to be set first (see Section 6).

6. Testing & Adjusting the Door Force Safety System

Door force adjustments are located on the side of the opener and must be properly set. The CLOSE FORCE adjustment controls the force required to reverse the door if an obstruction is encountered during closing. The OPEN FORCE adjustment controls the force required to stop the door if an obstruction is encountered during opening.

WARNING: Too much door force will interfere with the safety system's proper operation. Someone could be seriously injured or killed if the door force is set too high. A closing door might not reverse properly when required, and someone could be pinned under it. An opening door might not stop when going up, and someone hanging on the door could get pinned between the door and the header. Do not increase door force beyond what is required to move the door. DO NOT USE THE DOOR FORCE ADJUSTMENT TO COMPENSATE FOR A BINDING OR STICKING GARAGE DOOR. PERFORM THE SAFETY REVERSAL SYSTEM TEST (STEPS 4-6) MONTHLY!

Note: Read the following directions carefully before changing door force adjustments.

WARNING: Always perform the entire Door Force Safety System Test after making any adjustments to the opener.

Door Force Safety System Test

  1. Start with the door open. Use the remote control to cycle the door during this test.
  2. Adjusting the Close Force

    1. Turn the CLOSE FORCE adjustment 1/8-turn at a time in the DECREASE direction (counterclockwise) until the door stops and reverses mid-travel while going down.
    2. Turn the CLOSE FORCE adjustment 1/8-turn at a time in the INCREASE direction (clockwise) until the door fully closes without reversing.

    Safety Reversal System Test

    1. Lay a 2x4 board flat on the floor where it will be struck by the center of the door as it closes.
    2. Verify that the door reverses when it strikes the board. The door must reverse within two seconds after striking the board.
    3. Note: If the door stops after encountering the board and does not reverse, the CLOSE FORCE needs to be DECREASED.
    4. Repeat the Safety Reversal System Test until the door reverses within two seconds of striking the board.

    Visual Description: The document shows diagrams for adjusting close force: decreasing it until the door reverses mid-travel, and increasing it until the door closes fully without reversing. It also shows the safety reversal system test with a 2x4 board.

    Adjusting the Open Force

    1. Turn the OPEN FORCE adjustment 1/8-turn at a time in the DECREASE direction (counterclockwise) until the door stops mid-travel while going up.
    2. Turn the OPEN FORCE adjustment 1/8-turn at a time in the INCREASE direction (clockwise) until the door fully opens without stopping.

    Visual Description: The document shows diagrams for adjusting open force: decreasing it until the door stops mid-travel while going up, and increasing it until the door opens fully without stopping.

7. Replacing the Opener's Lamp

If the opener's safety lamp fails to light manually or when the opener is cycled, the light bulb needs replacing.

  1. Swing the light cover open to expose the light bulb and lamp socket.
  2. Replace the light bulb with a 100-watt maximum rough service bulb (sometimes called a garage door bulb).
  3. Swing the light cover closed, snapping it shut.
  4. Press the wall station's lamp button to test the lamp.

Visual Description: The document shows a diagram for replacing the lamp, illustrating swinging the cover open and installing a new bulb (up to 100 watts).
