z Be sure to select the rear one and lock it, making it unavailable to perform
any operations on the front operation panel.
If someone else can easily switch over to his or her desired panel, it is very dangerous
because he or she can operate the machine any time even though you are not ready for
it.
Be sure to lock the operation panel to avoid any major injuries.
z When more than one person are working, ensure good communication by
giving loud verbal instructions for safety purposes.
When several people are engaged in maintenance work, all of them cannot keep the
same observation (observer's eye) and the same way of thinking.
Whenever a person activates the machine, he or she should give a clear signal such as
"Power ON" to the others and the others should give a clear response such as "OK" to
the operator. No confirmation will result in a major injury.
It is important to have good timing between verbal instructions and responses, paying
attention to the intervals. People working should not get too much accustomed to this
signal exchange and no one should operate the machine without the best timing for
each other.
It will be most regrettable if an accident is caused by wrong operations.
z Before work, it is advisable to discuss whether or not it is surely required to
enter a moving area of the machine for repair work.
It is, of course, better to keep away from any moving area of the machine as long as
some other ways (even if a way might be somewhat troublesome) are possible for
repair.
Remember "Consideration leads to safe and efficient results!".
z Be sure to check the pattern program data for a test run by actually making
the machine perform a series of actions (from "Start" to "Stop"). After the good
performance is confirmed, proceed to your work in the safe range.
The machine works in various ways, depending on the executed pattern program and
the results of detection in execution.
It is required to carefully confirm that the [PAUSE] button works correctly and the
pattern program data for a test run does not have any deficiencies in addition to the
confirmation to a series of actions based on the pattern program data for a test run.
It should also be understood that safety is accredited only with the results, not with
the confirmation.
If you don't have a confidence, do not hesitate to ask another one repeatedly if the
steps (procedure) selected by you is correct or not.

z The machine must be operated by the person who made the pattern program
data and no one else should work as his/her substitute.
Every movement of the machine is determined by the pattern program data specified
as a current one.
If an operator who does not fully understand this data operates the machine as a
substitute of the data creator, there is a possibility to cause various misunderstandings.
This is something like asking someone else in place of you to drive a car in
darkness on a road that has no traffic signs.
z Be sure to turn off the power before leaving the machine unattended in the
middle of a test run.
Although you intend to leave the workplace for a short period of time, you may not be
able to come back for many hours. This happens frequently in our daily life.
After you have left the workplace, it cannot be avoided that someone else may operate
the machine.
Never leave the machine along with the power being turned ON, the safety doors
being unlocked, and the sensors being deactivated.
Be aware that you are charged with some responsibility not only for your co-workers
but also for the others.
z When some safety area sensors, safety covers, etc., must be detached
inevitably from the machine for servicing work, the machine and the
hazardous areas must be kept inaccessible to any person on the customer
side.
We never know when a person on the customer side enters the hazardous areas of the
machine (with the safety doors being open and the sensors being deactivated) during
our servicing work.
Keep the hazardous areas inaccessible, using a barricade tape, etc.

z Before performing a test run, it is required to set parameters to control the
variations in the movement based on the results of detection during the
operation.
Execute a test run for the running-in and performance check of the machine.
Before performing a test run, make the following settings in the "Test Mode" window
to prevent the machine from being activated in an unexpected way.
z Tick the "Missing Cmpnt Det Disabled", "Vertical Cmpnt Det Disabled", and
"Cmpnt Recog Pseudocomm" check boxes in the "Test Mode" window.
z Set parameters to prevent the machine from being set in the "Component
Replenishment", the "Recovery", or the "Alternate" mode.
Special caution should be paid to your maintenance work when test run
is performed with the covers being opened or the sensors being
deactivated.
z Be sure to keep your body away from the movable range of the machine
during operation.
z Do not disable the interlock unless absolutely necessary.
It is very dangerous if your work requires you to disable the interlock of the machine.
If the interlock has been disabled then always return it to enable as soon as possible.
z Confirm that no current is flowing in the power cable (to be connected to the
machine) with a tester at the delivery, the installation, or the transfer of the
machine.
