• Position opener on garage floor below the header bracket. Use packing material to protect the cover. Raise
rail until holes in the header sleeve and holes in the header bracket align. Join with clevis pins. Insert ring
fasteners to secure.

support. The opener must either be secured to a support or held firmly in place by another person.

INSTALLATION STEP 4
Position the Opener
Follow instructions which apply to your door type as illustrated.
SECTIONAL DOOR OR ONE-PIECE DOOR WITH TRACK
A 25 mm board laid flat is convenient for setting an ideal door-to-rail distance.
• Raise the opener onto a stepladder. You will need help at this point if the ladder is not tall enough.
• Open the door all the way and place a 25mm board laid flat on the top section beneath the rail.
• If the top section or panel hits the trolley when you raise the door, pull down on the trolley release arm
to disconnect inner and outer sections. Slide the outer trolley toward the motor unit. The trolley can remain
disconnected until Installation Step 12 is completed.
To prevent damage to garage door, rest garage door
opener rail on 25mm board or equivalent placed on top
section of door.
