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.

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.
EVERY YEAR
• Oil door rollers, bearings and hinges. The garage door opener does not require additional
lubrication. Do not grease the door tracks.
• (If applicable) 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.
