To Open the Door Manually
DISCONNECT THE TROLLEY:
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.
TO RE-CONNECT THE TROLLEY:
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.
