CHAPTER 5 Periodic Inspection
(3) Adjustment and parts replacement
1) After inspection, if you notice any adjustment or parts replacement is
needed, first turn off the controller and then enter the safeguard enclosure
to perform the necessary work. After adjustment or replacement is fin-
ished, again review the checkpoints outlined in (1) and (2) above.
2) If repair or parts replacement is required for the robot or controller, please
contact your YAMAHA dealer. This work requires specialized technical
knowledge and skill, so do not attempt it by yourself.
