WARNING Mechanical CAUTION WARNING WARNING Electrical WARNING CAUTION 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. Read the warnings carefully. WARNING WARNING WARNING WARNING When you see this Signal Word on the following pages, it will alert you to the possibility of damage to your garage door and/or the garage door opener if you do not comply with the cautionary statements that accompany it. [. . . ] · 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 one-inch high object (or 2x4 laid flat) on floor. CAUTION 1. The trolley will reconnect and the door will open between 4 and 5 feet. 2. Use the two buttons (1), (2) on the control panel to place the opener into limit setting mode: Press and hold the "Learn" button (2) while you press the "Limit" button on the left (1), then release both buttons. Press the left button (1) until the door travels up to the desired limit. If the door goes above the desired up limit, press the right button (2) to lower it. Place a one-inch board (or a 2x4 laid flat) on the floor, centered under the garage door. The door will travel down, touch the board, then reverse and stop in the up limit position. During step 5, if the door reverses before touching the board, increase the down force (See "Force Adjustment"), then repeat steps 1-5 above. If the door stops before reaching the up limit, increase the up force by small adjustments until it reaches the up limit. Repeat step 5. WARNING CAUTION To prevent damage to vehicles, be sure fully open door provides adequate clearance. Force Adjustment Antenna Limit Button (1) (Left) Indicator Light (3) Learn Button (2) (Right) (4) LOCK LIGHT 24 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. 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. Test the DOWN (close) force · Grasp the door bottom when the door is about halfway through DOWN (close) travel. Reversal halfway through down travel does not guarantee reversal on a one-inch obstruction. If the door is hard to hold or doesn't reverse, DECREASE the DOWN (close) force by turning the control counterclockwise. · If the door reverses during the down (close) cycle and the opener lights aren't flashing, INCREASE DOWN (close) force by turning the control clockwise. After each adjustment, run the opener through a complete travel cycle.
