Inspection
Inspection Schedule
Inspection items are divided into five stages (daily, 1-month, 3-month, 6-month, and 12-month), with additional items added at each stage. However, if the Manipulator is powered and operated for more than 250 hours in a month, add inspection items every 250, 750, 1,500, and 3,000 hours.

KEY POINTS
An overhaul should be performed after every 20,000 hours of Manipulator operation. Assuming an operation time of 8 hours per day and 250 hours per month, an overhaul should be performed every 80 months.
