Inspection of the hooka and their operating limit
Inspection of the opening, inspection for cracking and wear, and the operation limit
If any of the following conditions is found during the inspection of the hooks, never use them as
they are, but replace them.
The opening is extended to a degree that can be visually judged. The dimensions are different
from the specified dimensions.
Deformed or cracked.
In particular, pay attention to any bends or cracks in the shank of the hooks.
The wear amount in the section that contacts with the sling exceeds the operating limit.
The latch is damaged and or not functioning properly.
Check whether the bottom hook can rotate smoothly.
If it cannot rotate smoothly (rumbles when rotated by hand), the hook has reached the
operation usage limit.

For dimensions A, B, D, and E of the opening of the hooks, to be accurate, measure the actual
dimensions of the hooks of your product and record the values for later use as the references in
the inspection.
