5 Periodic Inspections

WARNING

Always turn the controller power OFF before starting periodic inspec- tions. Serious accidents could occur if the robot starts moving during the periodic inspection.

The inspection periods and general precautions are described in Chapter 4 Peri- odic Inspections. Always refer to that Chapter before starting this work.
