To Open the Door Manually
DISCONNECT THE TROLLEY:
The door should be fully
closed if possible. Pull down
on the emergency release
handle (so that the trolley
release arm snaps into a
vertical position) and lift the
door manually. The lockout
feature prevents the trolley
from reconnecting
automatically, and the door
can be raised and lowered
manually as often as
necessary.
TO RE-CONNECT THE TROLLEY:
Pull the emergency release
handle toward the opener at
a 45° degree angle so that
the trolley release arm is
horizontal. The trolley will
reconnect on the next UP or
DOWN operation, either
manually or by using the
door control or remote.
