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.
