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.
WARNING
The motor and speed reduction gear casing are extremely hot after auto-
matic operation, so burns may occur if these are touched. Before han-
dling these parts, turn OFF the controller, wait for a while and check that
the part has cooled.
The inspection periods and general precautions are described in Chapter 4 Peri-
odic Inspections. Always refer to that Chapter before starting this work.
