W A R N I N G
When the Rated Capacity Limiter is inoperative or malfunctioning, it must be repaired as
soon as reasonably possible. When a lift must be made without a properly functioning
load indicator or RCL, the designated lift supervisor must establish procedures for de-
termining load weights and load radii and conducting the lift safely.
