INSTALLATION STEP 7
Install the Light
• Install a 75 watt maximum light bulb in the socket.
The light will turn ON and remain lit for approximately
4-1/2 minutes when power is connected. Then the light
will turn OFF.
• If the bulb burns out prematurely due to vibration,
replace with a “Garage Door Opener” bulb.
NOTE: Use only standard light bulbs. The use of short
neck or specialty light bulbs may overheat the endpanel or
light socket.
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.
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.
INSTALLATION STEP 8
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" (2.54 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 fl oor. 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.
