The D4BL is provided with a shock-absorbing damper to protect
the D4BL from damage that may result from dropping the D4BL
during transportation. Be sure to remove the damper after
mounting the D4BL.
The mounting tolerance of the Operation Key is
±
0.3 mm vertically
or horizontally. Be sure to mount the D4BL correctly without leaning,
or the D4BL may soon break or wear out.

Do not drop the D4BL with the Operation Key inserted, otherwise
the Operation Key may deform or break.
Drop
The head is constructed so that it cannot be operated with
tools such as screwdrivers. Always use OMRON’s Operation
Key to operate the head in order to ensure the safety of the
machine and protect the D4BL from damage.
The Operation Key provided for the D4BL is not compatible
with that of the D4BS.
Mount the Operation Key and only secure it with screws that
will tighten when turned clockwise or counterclockwise.

Door Security
The D4BL may break soon if the door opens accidentally or
a space is present between the set zone of the Key and the
D4BL as shown below. This may be due to the weight of the
door, vibration of the machine, or bouncing of the door
against the rubber bumper. Be sure to apply appropriate
parts, such as hooks, so that no such space will exist.
