side or the other of the continuous loop hoist chain.

The disconnect chain must be released from the chain keeper
before the door will operate again electrically.

door from the door operator.

disconnect chain with manual hoist to electrically disable the
operator controls.

The disconnect chain may be locked in position by slipping
the end through the keyhole of the chain keeper mounted on
the wall.

To prevent possible SERIOUS INJURY from a moving chain:
• DISCONNECT electric power to the operator BEFORE manually
operating your door.
• If possible, use emergency disconnect ONLY when door is
CLOSED. Weak or broken springs or unbalanced door could
result in an open door falling rapidly and/or unexpectedly.
• NEVER use emergency disconnect unless doorway is clear of
persons and obstructions.
