To Open the Door Manually

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.
DISCONNECT THE TROLLEY
1
The door should be fully closed if possible.
2
Pull down on the emergency release handle so the trolley release arm
snaps to the vertical position. The door can now be raised and
lowered as often as necessary.
RECONNECT THE TROLLEY
1
Pull the emergency release handle toward the garage door opener
so the trolley release arm snaps to the horizontal position.
The trolley will reconnect on the next UP or DOWN operation, either
manually or by using the door control or remote control.
