Operation To Open the Door Manually 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. DISCONNECT THE TROLLEY 1 The door should be fully closed if possible. 2 Pull down on the emergency release handle. RECONNECT THE TROLLEY The lockout feature prevents the trolley from reconnecting automatically. 1 Pull the emergency release handle down and back (toward the opener). The door can then be raised and lowered manually as often as necessary. 2 To disengage the lockout feature, pull the handle straight down. The trolley will reconnect on the next UP or DOWN operation, either manually or by using the door control or remote control. 8
