5.4 About Overhaul

Robots which have been in operation for an extended period of time can suffer from wear and other forms of
deterioration. In regard to such robots, we define overhaul as an operation to replace parts running out of speci -
fied service life or other parts which have been damaged, so that the robots may be put back in shape for contin -
ued use. Overhaul interval for robots presumably varies with their operating conditions and thus with the degree of
the equipment's wear and loss of performance. As a rule of thumb, however, it is recommended that overhaul be
carried out before the total amount of servo-on time reaches the predetermined levels (24,000 hours for the robot
body and 36,000 hours for the controller). (See
timing of overhaul, contact your local service representative.
