The door should be fully closed 
if possible. Pull down on the 
emergency release handle (so 
that the trolley release arm 
snaps into a vertical position) 
and lift the door manually. The 
lockout feature prevents the 
trolley from reconnecting 
automatically, and the door can 
be raised and lowered manually 
as often as necessary.

Pull the emergency release 
handle toward the opener at an 
angle so that the trolley release 
arm is horizontal. The trolley 
will reconnect on the next UP or 
DOWN operation, either 
manually or by using the door 
control or remote.

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.
