Manual Operation

This operator has provisions for manually operating the door in case
of emergency or power failure. These operators are equipped with a
manual hoist. An electrical interlock will disable the electrical controls
when the hoist is used. Turn off power to the operator BEFORE
manually operating your door.
Electrical Interlock with Hoist
To operate the hoist, pull the disconnect chain (small chain) to
engage the hoist mechanism. The disconnect chain may be locked
in position by slipping the end through the keyhole of the chain
keeper mounted on the wall. Operate the door in the desired
direction by pulling on one side or the other of the continuous loop
hoist chain (large chain). The disconnect chain must be released
from the chain keeper before the door will operate again electrically.
