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.
The door should be fully closed if
possible. Pull down on the emergency
release handle and lift the door
manually. To reconnect the door to the
opener, press the door control button.
The lockout feature prevents the trolley
from reconnecting automatically, Pull
the emergency release handle down
and back (toward the opener). The
door can then be raised and lowered
manually as often as necessary. To
disengage the lockout feature, pull the
handle straight down. The trolley will
reconnect on the next UP or DOWN
operation.
