c. Inspect all sling hooks for spreading apart and/or wear. If hooks should become significantly
worn through normal use, the employ of a local weld shop should be enlisted to make
necessary replacements and/or repairs.
d. Warning labels should be kept clean and legible. If they should become worn, damaged, or
otherwise illegible replacements should be ordered.

e. Inspect all splice plate bolted connections for tightness. A gap between the adjoining places of
two adjacent load bar sections could be indicative of bolt loosening. Replacement bolts can be
ordered from Jaypro or procured at any local hardware store. Important: Replace only with
Grade 8 or better hex head bolts (higher grade numbers are better – higher strength steel).

f. Tighten bolts if necessary using the outline below for proper tightening sequence of the bolts.
