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.
