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.
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.
