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. Maintenance EVERY MONTH • Manually operate door. If it is unbalanced or binding, call a trained door systems technician. • Check to be sure door opens and closes fully. Adjust if necessary, see page 24. • Test the safety reversal system. Adjust if necessary, see page 25. THE REMOTE CONTROL BATTERY EVERY YEAR • Oil door rollers, bearings and hinges. The garage door opener does not require additional lubrication. Do not grease the door tracks. • Test the battery and consider replacing the battery to ensure the garage door opener will operate during an electrical power outage, see page 26 to test the battery backup. EVERY TWO TO THREE YEARS • Use a rag to wipe away the existing grease from the garage door opener rail. Reapply a small layer of white lithium grease to the top and underside of the rail surface where the trolley slides.
