Start
(4) Safety Measures
● When the work is carried out with 2 or more persons, make it clear who is to
be the “leader” and who to be the “follower(s)” and communicate well with
each other to ensure the safety of the workers.
● When the product is under operation or in the ready mode, take the safety
measures (such as the installation of safety and protection fence) so that
nobody can enter the area within the robot’s movable range.
When the robot under operation is touched, it may result in death or serious
injury.
● Make sure to install the emergency stop circuit so that the unit can be
stopped immediately in an emergency during the unit operation.
● Take the safety measure not to start up the unit only with the power turning
ON. Failure to do so may start up the machine suddenly and cause an injury
or damage to the product.
● Take the safety measure not to start up the machine only with the
emergency stop cancellation or recovery after the power failure. Failure to
do so may result in an electric shock or injury due to unexpected power
input.
● When the installation or adjustment operation is to be performed, give clear
warnings such as “Under Operation; Do not turn ON the power!” etc.
Sudden power input may cause an electric shock or injury.
● Take the measure so that the work part is not dropped in power failure or
emergency stop.
● Wear protection gloves, goggle or safety shoes, as necessary, to secure
safety.
● Do not insert a finger or object in the openings in the product. Failure to do
so may cause an injury, electric shock, damage to the product or fire.
● When releasing the brake on a vertically oriented actuator, exercise
precaution not to pinch your hand or damage the work parts with the
actuator dropped by gravity.
5 Teaching ● When the work is carried out with 2 or more persons, make it clear who is to
be the “leader” and who to be the “follower(s)” and communicate well with
each other to ensure the safety of the workers.
● Perform the teaching operation from outside the safety protection fence, if
possible. In the case that the operation is to be performed unavoidably
inside the safety protection fence, prepare the “Stipulations for the
Operation” and make sure that all the workers acknowledge and understand
them well.
● When the operation is to be performed inside the safety protection fence,
the worker should have an emergency stop switch at hand with him so that
the unit can be stopped any time in an emergency.
● When the operation is to be performed inside the safety protection fence, in
addition to the workers, arrange a watchman so that the machine can be
stopped any time in an emergency. Also, keep watch on the operation so
that any third person can not operate the switches carelessly.
● Place a sign “Under Operation” at the position easy to see.
● When releasing the brake on a vertically oriented actuator, exercise
precaution not to pinch your hand or damage the work parts with the
actuator dropped by gravity.
* Safety protection Fence : In the case that there is no safety protection fence,
the movable range should be indicated.

6 Trial Operation ● When the work is carried out with 2 or more persons, make it clear who is to
be the “leader” and who to be the “follower(s)” and communicate well with
each other to ensure the safety of the workers.
● After the teaching or programming operation, perform the check operation
one step by one step and then shift to the automatic operation.
● When the check operation is to be performed inside the safety protection
fence, perform the check operation using the previously specified work
procedure like the teaching operation.
● Make sure to perform the programmed operation check at the safety speed.
Failure to do so may result in an accident due to unexpected motion caused
by a program error, etc.
● Do not touch the terminal block or any of the various setting switches in the
power ON mode.
Failure to do so may result in an electric shock or malfunction.
7 Automatic
Operation
● Check before starting the automatic operation or rebooting after operation
stop that there is nobody in the safety protection fence.
● Before starting automatic operation, make sure that all peripheral equipment
is in an automatic-operation-ready state and there is no alarm indication.
● Make sure to operate automatic operation start from outside of the safety
protection fence.
● In the case that there is any abnormal heating, smoke, offensive smell, or
abnormal noise in the product, immediately stop the machine and turn OFF
the power switch. Failure to do so may result in a fire or damage to the
product.
● When a power failure occurs, turn OFF the power switch. Failure to do so
may cause an injury or damage to the product, due to a sudden motion of
the product in the recovery operation from the power failure.
