D4DL
Locking the Door
The D4DL may eventually break if the door opens accidentally due
to the weight of the door, the vibration of the machine, or the bounc-
ing of the door against the rubber bumper.
Furthermore, the door may not unlocked if force is imposed on the
operation key.
Do not use the casing of the D4DL as a locking mechanism for the
door in such cases and be sure to prepare a special lock within the
lock range of the D4DL (i.e., 0.5 to 3 mm).
