tion, lubrication, adjustment and general preventive maintenance is followed. We recommend
the following schedule:

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 function-
ing load indicator or RCL, the designated lift supervisor must establish procedures for
determining load weights and load radii and conducting the lift safely
