To prevent possible SERIOUS INJURY or DEATH from a
falling garage door:
• If possible, use emergency release handle to disengage
trolley ONLY when garage door is CLOSED. Weak or
broken springs or unbalanced door could result in an
open door falling rapidly and/or unexpectedly.
• NEVER use emergency release handle unless garage
doorway is clear of persons and obstructions.
• NEVER use handle to pull door open or closed. If rope
knot becomes untied, you could fall.

INSTALLATION STEP 8
Install the Lights and Lens
• Install a 100 watt maximum light bulb in each
socket. Light bulb size should be A19, standard
neck only. The lights will turn ON and remain lit for
approximately 4-1/2 minutes when power is
connected. Then the lights will turn OFF.
• Insert bottom lens tabs into slots on chassis. Tilt
towards chassis to engage top tabs, then drop
down gently into place (see illustration).
• To remove, depress both top lens tabs. Tilt lens
slightly outward and down, then pull out to clear
bulbs. Use care to avoid snapping off bottom lens
tabs.
• Use A19, standard neck garage door opener bulbs
for replacement.
NOTE: Use only standard light bulbs. The use of
short neck or speciality light bulbs may overheat the
endpanel or light socket.
INSTALLATION STEP 9
Attach the Emergency Release
Rope and Handle
• 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 at
least 1" (2.5 cm) 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 (1.83 m)
above the floor. Ensure that the rope and handle
clear the tops of all vehicles to avoid
entanglement. Secure with an overhand knot.
NOTE: If it is necessary to cut the rope, heat seal
the cut end with a match or lighter to prevent
unraveling.
To prevent possible OVERHEATING of the endpanel or
light socket:
• DO NOT use short neck or specialty light bulbs.
• DO NOT use halogen bulbs. Use ONLY incandescent.
To prevent damage to the opener:
• DO NOT use bulbs larger than 100W.
• ONLY use A19 size bulbs.
