3.15 Affixing the warning
label
Never modify the robot unit, robot controller, teach pendant or
other devices.
If your robot uses welding guns, paint spray nozzles, or other
end-effectors requiring cleaning, it is recommended that the
cleaning process be carried out automatically.
Sufficient illumination should be assured for safe robot operation.
If there is any risk of workers being injured in the event that the
object being held by the end-effector is dropped or thrown by the
end-effector, consider the size, weight, temperature and
chemical nature of the object and take appropriate safeguards to
ensure safety.
Place the warning label packaged
with the robot on the exit/entrance
of the safety fence or in a position
where it is easy to see.
