Follow any specific installation instructions issued by the supplier and the general requirements given overleaf. Try the block to ensure that it operates correctly and that the brake is effective. Ensure the chain is not twisted; it must move freely. The bottom hook must reach the lowest position required without the chain running fully out.

Before lifting load, check for twists in the load chain. A twist can occur if the lower hook block has been capsized
between the strands of chain. Reverse the capsize to remove twist.

capsized lower hook block


Explanation:
I can't access your file from work, but if it's talking about hooks, I'm pretty sure it's referring to capsized lower hook block. This might cause a twist in the chain, so the instruction is to check for it before operation. The linked file is one of many examples you will find by searching for "capsized hook block" (the relevant passage is on page 6, under "Checking for twist in load chain").

Here "tombo" is a printing jargon=paper margin to trim out --> hook tombo --> hook burr. See: http://www.google.co.th/search?hl=th&biw=1280&bih=605&q=”トンボ...

disagree  Raitei: Sorry. Search again.

  -> Did you work with hook "tombo"? I did it 3 years at a Yokohama steel mill. We had no Google search functions in those days (year 1975-8).

disagree  Julian Rippon: Sorry to disagree, but if you look at the picture in the document attached to the original message you will see that this relates to a hook on a chain, not to a burr.
