(4) Safety measures 
● When working with two or more persons, make it clear who is to be in charge 
and communicate well with each other to ensure safety. 
● When the product is operating or in the ready mode, take safety measures 
(such as the installation of safety/protection fences) so that nobody can enter 
the area within the robot's movable range. Contact with an operating robot may 
lead to death or serious injury. 
● Be sure to install an emergency stop circuit so that the unit can be stopped 
immediately in an emergency during operation. 
● Take safety measures such that turning the power ON alone will not start up the 
unit. Otherwise, this may cause the product to start unexpectedly, leading to 
injury or product damage. 
● Take safety measures such that emergency stop cancel or recovery after 
power failure alone will not start up the unit. Otherwise, this may lead to injury 
or equipment damage. 
● When installation or adjustment operation is to be performed, display signs 
such as "Operating: No Power ON!" etc. Sudden power input may cause 
electric shock or injury. 
● Take measures to prevent workpieces, etc. from falling during power failures or 
emergency stop. 
● Wear protection gloves, goggles and safety shoes, as necessary, to secure 
safety. 
● Do not insert fingers or objects into the openings in the product. Otherwise,  
this may lead to injury, electric shock, product damage, or fire. 
● When releasing the brake on a vertically oriented actuator, be careful that it 
does not fall under its own weight, catching the operator's hand or damaging 
workpieces. 
5  Teaching  ● When working with two or more persons, make it clear who is to be in charge 
and communicate well with each other to ensure safety. 
● Perform teaching operation from outside the safety/protection fence,  
if possible. If operation must be performed within the safety/protection fence, 
prepare "Work Regulations" and make sure that all the workers acknowledge 
and understand them well. 
● When operation is to be performed inside the safety/protection fence,  
operators should have emergency stop switches available at hand so that the 
unit can be stopped at any time if abnormalities occur. 
● When operation is to be performed inside the safety/protection fence,  
have a monitor standing by in addition to the operator(s) so that the unit can be 
stopped at any time if abnormalities occur. Also, keep watch on the operation 
so that a third party cannot operate the switches carelessly. 
● Place a sign indicating "Operating" where it can be seen easily. 
● When releasing the brake on a vertically oriented actuator, be careful that it 
does not fall under its own weight, catching the operator's hand or damaging 
workpieces. 
* Safety/protection fence: If there is no safety/protection fence, the movable 
range should be indicated.
