Maintenance
and Inspection
Ɣ 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.
Ɣ Perform the work out of 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.
Ɣ When the work is to be performed inside the safety protection fence,
basically turn OFF the power switch.
Ɣ 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.
Ɣ 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.
Ɣ Place a sign “Under Operation” at the position easy to see.
Ɣ For the grease for the guide or ball screw, use appropriate grease
according to the Operation Manual for each model.
Ɣ Do not perform the dielectric strength test. Failure to do so may result in a
damage to the product.
Ɣ 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.
Ɣ The slider or rod may get misaligned OFF the stop position if the servo is
turned OFF. Be careful not to get injured or damaged due to an
unnecessary operation.
Ɣ Pay attention not to lose the cover or untightened screws, and make sure
to put the product back to the original condition after maintenance and
inspection works.
Use in incomplete condition may cause damage to the product or an injury.
