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.
TO RE-CONNECT 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.
