TABLE OF CONTENTS Introduction 2-5 Adjustment 23-25 Safety symbol and signal word review . . 25 Operation 26-31 Assembly 6-7 Attach the rail to 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 1-1/2" (3. 8 cm) 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. Do not increase the force beyond the minimum amount required to close the door. Test the UP (open) force · Grasp the door bottom when the door is about halfway through UP (open) travel. If the door is hard to hold or doesn't stop, DECREASE UP (open) force by turning the control counterclockwise. After each adjustment, run the opener through a complete travel cycle. · If the door doesn't open at least 5 feet (1. 5 m), INCREASE UP (open) force by turning the control clockwise. After each adjustment, run the opener through a complete travel cycle. Without a properly installed safety reversal system, persons (particularly small children) could be SERIOUSLY INJURED or KILLED by a closing garage door. · Too much force on garage door will interfere with proper operation of safety reversal system. · NEVER increase force beyond minimum amount required to close garage door. · NEVER use force adjustments to compensate for a binding or sticking garage door. · 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.
