designed and tested to offer safe service provided it is installed, operated, maintained and tested in strict accordance with the instructions and warnings contained in this manual. When you see these Safety Symbols and Signal Words on the following pages, they will alert you to the possibility of serious injury or death if you do not comply with the warnings that accompany them. [. . . ] · Open door adjustment: decrease UP travel limit - Turn the UP limit adjustment screw counter-clockwise 4 turns. - Manually raise the door to the open position (parallel to the floor), and lift the door arm to the trolley. The arm should touch the trolley just in back of the door arm connector hole. Refer to the fully open trolley/door arm positions in the illustration. · Closed door adjustment: decrease DOWN travel limit - Turn the DOWN limit adjustment screw clockwise 4 complete turns. Door Bracket Ring Fastener Lock Washers 5/16" Nuts 5/16"-18 Clevis Pin 5/16"x1-1/4" Straight Arm Bolts 5/16"-18x7/8 Curved Door Arm Figure 4 - Press the Door Control push button. 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. 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. NOTE: When setting the up limit on the following page, the door should not have a "backward" slant when fully open as illustrated below. A slight backward slant will cause unnecessary bucking and/or jerking operation as the door is being opened or closed from the fully open position. Figure 5 Inner Trolley Outer Trolley Door Arm Connector Hole Door Arm Emergency Release Handle Closed Door Inner Trolley Outer Trolley Correct Angle Door Arm Open Door Door with Backward Slant (Incorrect) 22 ADJUSTMENT STEP 1 Adjust the UP and DOWN Travel Limits Limit adjustment settings regulate the points at which the door will stop when moving up or down. · 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 (Adjustment Step 3, page 25). NOTE: Repeated operation of the opener during adjustment procedures may cause the motor to overheat and shut off. If anything interferes with the door's upward travel, it will stop. If anything interferes with the door's downward travel (including binding or unbalanced doors), it will reverse. HOW AND WHEN TO ADJUST THE LIMITS · If the door does not open completely but opens at least five feet (1. 5 m): Increase up travel. NOTE: To prevent the trolley from hitting the cover protection bolt, keep a minimum distance of 2-4" (5 cm - 10 cm) between the trolley and the bolt. · If door does not open at least 5 feet (1. 5 m): Adjust the UP (open) force as explained in Adjustment Step 2. If door still won't close completely and the trolley bumps into the pulley bracket (page 4), try lengthening the door arm (page 21) and decreasing the down limit. · If the opener reverses in fully closed position: Decrease down travel. Without a properly installed safety reversal system, persons (particularly small children) could be SERIOUSLY INJURED or KILLED by a closing garage door.
