INSTALLATION STEP 7
Install the Lights and Lenses
Install a 75 watt maximum light bulb in each
socket. The lights will turn ON and remain lit for
approximately 4-1/2 minutes when power is
connected. Then the lights will turn OFF.
Slide lenses into guides. Snap bottom tabs into
lens slots.
Reverse the procedure to remove the lenses.
If the bulbs burn out prematurely due to vibration,
replace with a Garage Door Opener bulb.
NOTE: For convenience, the lenses may be installed
after Adustment Step 4 on page 26.
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" 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.
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 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.
