manually or by using the door
control or remote.

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.
