(Caution) 1. When using the AK device, set whether to use the AK device after conrming how to select the
auto-lifter function. (Refer to “
III-11. Setting of the auto lifter function” p.39.)
2. Be sure to securely insert the respective connectors after checking the inserting directions since
all connectors have the inserting directions. (When using a type with lock, insert the connectors
until they go to the lock.) The sewing machine is not actuated unless the connectors are inserted
properly. In addition, not only the problem of error warning or the like occurs, but also the sewing
machine and the control box are damaged.

(Caution) Be sure to turn OFF the power before con-
necting the connector.
