Mechanical 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. [. . . ] 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. 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. NOTE: 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 5 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. · Incorrect adjustment of garage door travel limits will interfere with proper operation of safety reversal system. · If one control (force or travel limits) is adjusted, the other control may also need adjustment. · After ANY adjustments are made, the safety reversal system MUST be tested. Door MUST reverse on contact with 1-1/2" high (3. 8 cm) object (or 2x4 laid flat) on floor. To prevent damage to vehicles, be sure fully open door provides adequate clearance. Cover Protection Bolt 2-4" (5-10 cm) Left Side Panel Limit Adjustment Screws ADJUSTMENT LABEL · If the door reverses when closing and there is no visible interference to travel cycle: If the opener lights are flashing, the Safety Reversing Sensors are either not installed, misaligned, or obstructed. If the door is binding or unbalanced, call for a trained door systems technician. If the door is balanced and not binding, adjust the DOWN (close) force. See Adjustment Step 2. 23 ADJUSTMENT STEP 2 Adjust the Force Force adjustment controls are located on the back panel of the motor unit. Force adjustment settings regulate the amount of power required to open and close the door. If the forces are set too light, door travel may be interrupted by nuisance reversals in the down direction and stops in the up direction. Weather conditions can affect the door movement, so occasional adjustment may be needed.
