WARNING
To prevent possible SERIOUS INJURY or DEATH from a
falling garage door:
CAUTION
• 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 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.
