PREVENTIVE MAINTENANCE
In addition to the inspection procedure on page
12, a preventive maintenance program should be
established to prolong the useful life of the hoist
and maintain its reliability and continued safe use.
The program should include the periodic and fre-
quent inspections with particular attention being
paid to the lubrication of the various components
using the recommended lubricants (see page 15).
