To Open the Door Manually
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 push bar.
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, either manually or by using the
door control or remote.
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.
