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.
NOTE: Handle should hang 6 feet (1.5 m) above floor.
Ensure that the rope and handle clear the tops of all
vehicles to avoid entanglement.
