Appendix D: Preventative Maintenance
Every 1 to 2 years, the following preventative Maintenance procedures should be performed. For robots
that are continuously moving 24 hours per day, 7 days a week at moderate to high speeds, a one-year
schedule is recommended. For robots with low duty cycles and low to moderate speeds, these
procedures should be performed at least once every two years.
