[. . . ] Closed Door Adjustment: Decrease DOWN limit · Turn the DOWN limit adjustment screw clockwise 5 complete turns. · Manually close the door and lift the door arm to the trolley. The arm should touch the trolley just ahead of the door arm connector hole. Refer to the fully closed trolley/door arm positions in the illustration. One full turn equals 2" of trolley travel. Connect the door arm to the trolley. · Close the door and join the curved arm to the connector hole in the trolley with the remaining clevis pin. If the door has a slight "backward" slant in full open position as shown in the illustration, decrease the UP limit until the door is parallel to the floor. 23 Adjustment Section: Pages 24 ­ 26 Adjustment Step 1 Adjust the UP and DOWN Limits Improper adjustment of the travel limits will interfere with the proper operation of the safety reverse system. The door might not reverse when required and could seriously injure or kill someone under it. Test the safety reverse system following all adjustments to the travel limits. See page 26. WARNING Limit adjustment settings regulate the points at which the door will stop when moving up or down. The door will stop in the up direction if anything interferes with door travel. The door will reverse in the down direction if anything interferes with the door travel (including binding or unbalanced doors). · Does the door stay closed and not reverse unintentionally when fully closed?If your door passes both of these tests, no limit adjustments are necessary. Left Side Panel INCREASE INCREASE UP DOWN TRAVEL TRAVEL INCREASE INCREASE DOWN UP TRAVEL TRAVEL Limit Adjustment Screws Limit Adjustment Label Limit Adjustment Label Adjustment procedures are outlined below. Repeated operation of the opener during adjustment procedures may cause the motor to overheat and shut off. Use a screwdriver to make limit adjustments. How and When to Adjust the Limits If the door does not open completely but opens at least five feet Increase up travel. If door does not open at least 5 feet: Adjust the UP (open) force as explained in Adjustment Step 2. If door still won't close completely, try lengthening the door arm. (Page 22. ) If you have adjusted the door arm to the maximum length and the door still will not close completely, lower the header bracket. If the door reverses when closing and there is no visible interference to travel cycle If the opener lights are flashing, the Safety Reversing Sensor is obstructed. If the door is not binding or unbalanced, adjust the DOWN (close) force. [. . . ] Model 81LM "Smart" Remote Control: Includes visor clip.
