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.
Using the Wall-Mounted Door Control
Press the push button to open or close the
door. Press again to reverse the door during
the closing cycle or to stop the door while
it's opening.
