Automatic Garage Door Opener OWNER INSTALLATION AND USER MANUAL

Step 26: Connecting Door Arm to Door

Door Mounted Bracket

Visually align cushion arm connecting hole with middle

hole of door bracket by rotating tube section in appropriate

direction.

Release trolley (cushion arm attached) with manual

release cord and pull trolley a few inches toward motor.

Now rotate cushion arm tube section 2 turns

counterclockwise to provide a cushion when door is closed

or encounters an obstruction. Align connecting hole in

cushion arm to middle hole in door

bracket; insert 3/8” dia. bolt and

tighten locking nut, allowing for free

pivoting of arm.

Note: Do not over tighten locking

nut, as this will cause binding

between cushion arm and door

bracket.

WARNING: Failure to secure door

arm to door bracket with locking nut can cause door arm to become disengaged from

the trolley and fall, resulting in possible damage or personal injury.

Step 27: Setting Door Close Travel Plus “Contact Obstruction Sensing” Test

With wall control up/down button, activate door to

full open position; reactivate to close position. The

door should stop on the floor with the cushion arm

and the bottom door seal slightly compressed. If the

door reverses off the floor, turn close travel knob 1/4

turn “less”. If door is not completely closed, turn

travel knob 1/4 turn “more”. Repeat if necessary.

IMPORTANT! Test “Contact Obstruction Sensing Feature”

IMPORTANT: After installing opener, the door must reverse when it contacts a 1 inch high object on the floor.

Activate the door to the full, open

position and place a 1” (25mm) solid

test obstacle on the floor under the

garage door. Activate the door to the

closed position. The door should

reverse upon contact with the 1”

obstacle.

If door stops on the 1” obstacle, adjust

the close travel knob 1/4 turn “more”

until door reverses upon contact with

obstacle. Repeat if necessary.

When the door reverses, remove the test object and run the full cycle of open and close of the door. Door should not

reverse when it comes to the fully closed position.

Note: If opener fails to pass this test, repeat Step 27. Also see Adjustment #2, page 28, (Contact Obstruction

Sensing Adjustment).
