replace them with "Garage Door Opener" bulbs.
• Slide lenses into guides as shown. Snap bottom
tabs into lens slots.
• For convenience, the lenses may be installed

Attach the Manual Release
Rope and Handle
Do not use the red handle to pull the door
open or closed.
The rope knot could become
untied and you could fall. Use the manual
release only to disengage the trolley and, if
possible, only when the door is closed.
Garage doors are heavy. If the door is open
when the handle is pulled, the door could
close inadvertently if it is not properly
balanced. Serious injury may result to persons
under the door. Make sure the doorway is clear
of persons and obstructions before pulling
handle when door is open.
• Thread one end of the rope through the hole in the
top of the red handle so "NOTICE" reads right side
up as shown. Secure with an overhand knot.
The knot should be at least 1" from the end of the
rope to prevent slipping.
• Thread the other end of the rope through the hole in
the release arm of the outer trolley.
• Adjust rope length so the handle is 6 feet above the
floor. Secure with an overhand knot .
If it is necessary to cut the rope, heat seal the cut
end with a match or lighter to prevent unraveling.
