EMERGENCY DISCONNECT SYSTEM

TO DISCONNECT DOOR FROM OPERATOR
The door should be in the fully closed position 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.
