STEP 6 Attach the Emergency Release Rope and Handle
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
l
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.
l
NEVER use handle to pull door open or closed. If rope knot becomes untied, you could fall.
l
1. Insert one end of the emergency release rope through the handle. Make sure that "NOTICE" is right side
up. Secure with an overhand knot at least 1" (2.5 cm) from the end of the rope to prevent slipping.
2. Insert the other end of the emergency release rope through the hole in the trolley release arm. Mount the
emergency release within reach, but at least 6 feet (1.83 m) above floor, avoiding contact with vehicles to
prevent accidental release and secure with an overhand knot.
NOTE: If it is necessary to cut the emergency release rope, seal the cut end with a match or lighter to prevent
unraveling. Ensure the emergency release rope and handle are above the top of all vehicles to avoid entanglement.
