[. . . ] 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 Do not make any limit adjustments until the safety reversing sensors are completely installed. 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 unless the reversing test fails (See page 26). Repeated operation of the opener during adjustment procedures may cause the motor to overheat and shut off. Read the procedures carefully before continuing on to Adjustment Step 2. Use a screwdriver to make limit adjustments. WARNING 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. Left Side Panel Limit Adjustment Screws Adjustment Label 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. (See 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. See Adjustment Step 2. 24 Adjustment Step 2 Adjust the Force WARNING Too much force on the door will interfere with the proper operation of the safety reverse system. The door might not reverse properly when required and could seriously injure or kill someone under it. Do not increase the force beyond the minimum amount required to close the door. Do not use the force adjustments to compensate for a binding or sticking garage door. Test the safety reverse system following all adjustments to force levels.
